 # Gravity Monitor for Beer Brewing
 
-This software can be used with iSpindle hardware and utilizes the same hardware configuration. No code has been reused from the iSpindle project. 
+GravityMon is a replacement firmware for the iSpindle firmware. It's 100% compatible with the iSpindle hardware design so it does not require any hardware changes.
 
-I started this project out of curiosity for how a motion sensor is working and since I like to brew beer this was the result. 
+Installation can be made using https://www.brewflasher.com
 
-After 6 months of testing I believe this is working as planned. It give accurate readings same as the orginal iSpindel software. 
+The main differences:
+---------------------
 
-Version history
-* v0.4 First official version with 5+ brews on record. 
+* Operates in two modes gravity monitoring and configuration mode (simplify calibration)
+* Modern web based UI for configuration (in config mode)
+* REST API
+* Send data to multiple endpoints when pushing data (2xhttp, brewfather, influxdb v2, mqtt supported)
+* Automatic temperature adjustment of gravity reading
+* OTA support from local webserver
+* Built in function to create gravity formulas, no need for additional software, just enter tilt/gravity. 
+* Visual graph showing how formula will be interpreted
+* Using the temperature sensor in gyro instead of DS18B20 (faster)
+* Built in performance measurements (used to optimise code)
+* SSL support in standard HTTP and MQTT connections.
 
-Lower priority
-* Add support for Plato in device (today it assumes that formula is in SG). 
-* Add support for converting between SG/Plato in device.
-* Add support for Blynk as endpoint
-* Add support for https connections (push) - [need to reduce memory usage for this to work, gets out of memory error]
-* Add support for https web server (will require certificates to be created as part of build process)
-* Add support for WifiManager Secure access, depends on support in library.
+No code has been reused from the iSpindle project. 
 
-# Functionallity
-
-I have made a few different design decision compared to the standard iSpindle software. 
-
-* The device operate in two modes, __always-on__ or __deep-sleep__. Always on can be triggered in two ways: Connected to charger and the power is over 4.1V or the device is lying flat (angle is approx 90 degrees). 
-
-* Configuration options have been moved to a web gui and is accesible when the device is in __always-on__ mode. The Wifi portal only need to be used for changing WIFI network. 
-
-* The software also has built in OTA support so new versions can be downloaded from a local webserver and checks are done during startup and the device is in __always-on__ mode.
-
-* Temperature calibration has been added for the DS18B20 sensor so you can adjust the temperature sensor readings if there is a need. When the device is in __always-on__ mode the temperature will rise in the container so the value will increase and not reflect the temperature for the surronding the container.
-
-* There is an option to automatically correct the gravity calculation based on the temperature. Useful if you are fermenting at lower temperatures. It's possible to build this into the normal gravity formula but this is an easier option. Just make sure that the calibration is done at 20°C.
-
-* The software will read the motion sensor 50 times and use the average to calculate the angle. If the readings show that the device is moving it will wait a few seconds and retry the operation again to make sure that no invalid angles should be reported. If the device is unsuccesful to get a valid angle within 10s it will go to sleep for 60s and then retry again (TODO: This will be adjusted after more testing).
-
-## Configuration 
-
-Configuration is accessed by entering the URL for the device, this will be the mDNS name __device.local__ or the IP adress. The following chapter assumes the device name is __gravmon__.
-
-### Index page
-
-http://gravmon.local/
-
-The main page shows the device readings; gravity, angle, temperature and battery charge. If the checkbox is active then the device will never go into sleep mode. This is useful if you are collecting angle/tilt for calibration. If this is unchecked the device will change mode as explained before.
-
-![Status](img/index.png)
-
-### Device page
-
-http://gravmon.local/device.htm
-
-The device page shows the device settings and software versions. 
-
-![Device](img/device.png)
-
-### Config page
-
-http://gravmon.local/config.htm
-
-* This page is divided into several categories of settings. The first one contains device settings, mDNS name, temperature format, sleep interval and gyro calibration data. The interval setting is the amount of time the device will be in sleep mode between readings (interval is in seconds). To simplify this you can also see the conversion to minutes / seconds next to the input field.
-
-* The sleep interval can be set between 10 - 3600 seconds (60 minutes). 
-
-* Calibration needs to be done or the device will not work correctly. Place the device flat on a surface with gyro up and press the calibrate button when it's stable. If no calibration data exist the device will not enter sleep-mode.
-
-![Config - Device](img/config1.png)
-
-* The second section contains the push settings, two URL's for http posts, Brewfather and settings for InfluxDB v2. 
-
-### This is the format used for standard http posts. 
-```
-{ 
-   "name" : "gravmon",      // mDNS name
-   "ID": "2E6753",          // esp device id
-   "token" : "gravmon",
-   "interval": 900,     
-   "temperature": 20.5,     // C or F based on setting, adjusted value.
-   "temp-units": "C",       // C or F based on setting
-   "gravity": 1.0050,       // Raw or temperature corrected gravity (based on setting)
-   "corr-gravity": 1.0050,  // Temperature corrected gravity 
-   "angle": 45.34,
-   "battery": 3.67,
-   "rssi": -12,
-   "run-time": 230,         // ms, Runtime for this reading, this is an additional field not part of the standard format
-}
-```
-
-### This is the format for Brewfather
-
-```
-{ 
-   "name" : "gravmon",      // mDNS name
-   "temp": 20.5,
-   "temp-unit": "C",
-   "battery": 3.67,
-   "gravity": 1.0050,
-   "gravity_unit": "G",     // G = SG, Plato is not yet supported
-}
-```
-
-### This is the format for InfluxDB v2
-
-```
-measurement,host=<mdns>,device=<id>,temp-format=<C|F>,gravity-format=SG,gravity=1.0004,corr-gravity=1.0004,angle=45.45,temp=20.1,battery=3.96,rssi=-18
-```
-
-![Config - Push](img/config2.png)
-
-* The third section contains the gravity formula and also option for doing temperature compensation. The calibration formula uses two keywords, temp and tilt. Temperature is in the selected device format. 
-
-* Gravity formula is compatible with standard iSpindle formulas so any existing calculation option can be used. I use the tool fermentrack for controlling my fermentation and I use this tool for calculating gravity. The formula can handle two keywords, __tilt__ and __temp__. This is an example of a formula; __0.00145*tilt^3+0.1445*tilt^2+0.00179*tilt+0.9436__ 
-
-* This is the formula used for temperature calibration (temp is in F). Cal = 20C.
-```
-gravity*((1.00130346-0.000134722124*temp+0.00000204052596*temp^2-0.00000000232820948*temp^3)/(1.00130346-0.000134722124*cal+0.00000204052596*cal^2-0.00000000232820948*cal^3))
-```
-![Config - gravity](img/config3.png)
-
-* Hardware settings contain settings for temperature sensor adjustment, voltage factor (to calulate the battery level) and OTA URL.
-
-* For the OTA to work, place the following files (version.json + firmware.bin) at the location that you pointed out in OTA URL. If the version number in the json file is newer than in the code the update will be done during startup.
-
-Example; OTA URL (don't forget trailing dash), the name of the file should be firmware.bin
-```
-http://192.168.1.1/firmware/gravmon/
-```
-
-Contents version.json
-```
-{ "project":"gravmon", "version":"0.3.0" }
-```

-# Building a device
-
-See the iSpindle documentation for building a device. 
-
-I've included my 3d sled that I use for my builds that allows for easy adjustment of the default angle. The stl files can be found under the stl directory.
-
-![Spindle sled](img/spindle.png)
-![Spindle sled with weight](img/spindle-weight.png)
-
-# Compiling the software
-
-I recommend that VSCODE with PlatformIO and Minfy extensions are used. Minify is used to reduce the size of the HTML files which are embedded into the firmware or uploaded to the file system. When using minify on a file, for example index.htm the output will be called index.min.htm. This is the file that will be used when buildning the image. 
-
-By default the html files are embedded but there are options to upload them to the file system to reduce the size of the image if the size becomes to large for OTA. 
-
-You can set the SSID and PWD as presets through platformio.ini by adding the settings to the following definitions:
-```
--D USER_SSID=\""\""           // =\""myssid\""
--D USER_SSID_PWD=\""\""       // =\""mypwd\""
-```
-
-There are more options in teh platform.ini file that enable/disable additional functions for logging level, pushing performance data to InfluxDB and more. If i get the time I will add some documentation around these.

+
+The latest version of this library may be found at:
+  http://www.pjrc.com/teensy/td_libs_OneWire.html
+
+OneWire has been maintained by Paul Stoffregen (paul@pjrc.com) since
+January 2010.
+
+DO NOT EMAIL for technical support, especially not for ESP chips!
+All project support questions must be posted on public forums
+relevant to the board or chips used.  If using Arduino, post on
+Arduino's forum.  If using ESP, post on the ESP community forums.
+There is ABSOLUTELY NO TECH SUPPORT BY PRIVATE EMAIL!
+
+Github's issue tracker for OneWire should be used only to report
+specific bugs.  DO NOT request project support via Github.  All
+project and tech support questions must be posted on forums, not
+github issues.  If you experience a problem and you are not
+absolutely sure it's an issue with the library, ask on a forum
+first.  Only use github to report issues after experts have
+confirmed the issue is with OneWire rather than your project.
+
+Back in 2010, OneWire was in need of many bug fixes, but had
+been abandoned the original author (Jim Studt).  None of the known
+contributors were interested in maintaining OneWire.  Paul typically
+works on OneWire every 6 to 12 months.  Patches usually wait that
+long.  If anyone is interested in more actively maintaining OneWire,
+please contact Paul (this is pretty much the only reason to use
+private email about OneWire).
+
+OneWire is now very mature code.  No changes other than adding
+definitions for newer hardware support are anticipated.
+

+  Search bug fix, Love Nystrom
+
+Version 2.2:
+  Teensy 3.0 compatibility, Paul Stoffregen, paul@pjrc.com
+  Arduino Due compatibility, http://arduino.cc/forum/index.php?topic=141030
+  Fix DS18B20 example negative temperature
+  Fix DS18B20 example's low res modes, Ken Butcher

+  PIC32 (chipKit) compatibility, Jason Dangel, dangel.jason AT gmail.com
+  Improvements from Glenn Trewitt:
+  - crc16() now works
+  - check_crc16() does all of calculation/checking work.
+  - Added read_bytes() and write_bytes(), to reduce tedious loops.
+  - Added ds2408 example.
+  Delete very old, out-of-date readme file (info is here)
+
+Version 2.0: Modifications by Paul Stoffregen, January 2010:
+http://www.pjrc.com/teensy/td_libs_OneWire.html
+  Search fix from Robin James
+    http://www.arduino.cc/cgi-bin/yabb2/YaBB.pl?num=1238032295/27#27
+  Use direct optimized I/O in all cases
+  Disable interrupts during timing critical sections
+    (this solves many random communication errors)
+  Disable interrupts during read-modify-write I/O
+  Reduce RAM consumption by eliminating unnecessary
+    variables and trimming many to 8 bits
+  Optimize both crc8 - table version moved to flash
+
+Modified to work with larger numbers of devices - avoids loop.
+Tested in Arduino 11 alpha with 12 sensors.
+26 Sept 2008 -- Robin James
+http://www.arduino.cc/cgi-bin/yabb2/YaBB.pl?num=1238032295/27#27
+
+Updated to work with arduino-0008 and to include skip() as of
+2007/07/06. --RJL20
+
+Modified to calculate the 8-bit CRC directly, avoiding the need for
+the 256-byte lookup table to be loaded in RAM.  Tested in arduino-0010

+Format editor
++++++++++++++
+
+To reduce the need for adding custom endpoints for various services there is an built in format editor that allows the user to customize the format being sent to the push target. 
+
+.. warning::
+
+   Since the format templates can be big this function can be quite slow on a small device such as the esp8266. 
+
+.. image:: images/format.png
+  :width: 800
+  :alt: Format editor
+
+You enter the format data in the text field and the test button will show an example on what the output would look like. If the data cannot be formatted in json it will just be displayed as a long string.
+The save button will save the current formla and reload the data from the device. 
+
+.. tip::
+
+   If you save a blank string the default template will be loaded.
+
+These are the format keys available for use in the format.

+Compiling the software
+######################
+
+Tools
+=====
+I use the following tools in order to build and manage the software:
+
+* Visual Studio Code
+* PlatformIO
+* Git for Windows
+* VSCode plugin: Minify (used to minimise the html files)
+
+Code Formatting
+===============
+I use pre-commit and their cpp style checks to validate the code. Plugin defintions are found in **.pre-commit-config.yaml**
+
+`Pre-Commit <https://www.pre-commit.com>`_
+
+.. note::
+
+  There is not yet any automatic checks since this does not work on Windows. It works if running under WSL2 with Ubuntu.
+
+
+Targets 
+=======
+In the platformio config there are 3 targets defined
+
+* gravity-debug; Maximum logging for trouble shooting, deep sleep is disabled.
+* gravity-release; Standard release
+* gravity-perf; Standard release but contains code for measuring performance 
+* gravity32-perf: Experimental version for ESP32.
+
+.. note::
+  There is an experimental ESP32 target but since platformio only supports SDK 1.0.6 and the WIFI connection is really slow compared to ESP8266, 
+  so the recommendation is to wait for support on 2.0.x branch. With the tested version an wifi connection takes 3-8s on a ESP32 compared 
+  to 0.5s on an ESP8266. There is also a bug in OneWire connected to ESP32 that has not been fixed in the main repository yet.
+
+.. warning::
+  The debug target can be unstable and crash the device under certain circumstanses. Excessive logging to the serial port can cause corruption and crashes. 
+  So only enable enough debugging to troubleshoot your changes.

+Configuration
+#############
+
+The device can operate in two modes and must be in ``configuration mode`` in order for the web server to be active.
+
+One of the following conditions will place the device in ``configuration mode``:
+
+- Gyro has not been calibrated
+- Sleep mode has been disabled in the web interface
+- Placed in horizontal mode 85-90 degrees
+- Charger connected >4.15V
+

+
+Configuration is accessed by entering the URL for the device, this will be the mDNS name *device.local* or the IP adress. The following chapter assumes the device name is *gravmon*.
+
+The main page shows the device readings; gravity, angle, temperature and battery charge. If the checkbox is active then the device will never go into sleep mode. This is useful if 
+you are collecting angle/tilt for calibration. If this is unchecked the device will change mode as explained before.
+
+.. tip::
+
+   If you are connected to the device via a serial console (speed: 115200) you can see the connection sequence and get the Unique ID and IP adress from there.

+   This is unique name of the device which is set in the configuration, also known as MDNS name.
+
+* **Device ID:** 
+
+   This is unique identifier for the device (ESP8266 id), this is required when using the API as an API Key to safeguard 
+   against faulty requests. This is the ESP8266 chip ID, so it should be unique.

+
+* **Device name:** 
+
+   This is unique name for the device. It will be used in pushing data as well as mDNS name on the network (<name>.local)
+
+* **Temperature format:** 
+
+   Choose between Celsius and Farenheight when displaying temperature. 
+
+* **Interval:** 
+
+   This defines how long the device should be sleeping between the readings when in `gravity monitoring` mode. You will also see 
+   the values in minutes/seconds to easier set the interval. 900s is a recommended interval.  The sleep interval can 
+   be set between 10 - 3600 seconds (60 minutes). 
+
+.. note::
+
+   A low value such as 30s will give a lifespan of 1-2 weeks and 300s (5 min) would last for 3+ weeks. This assumes that 
+   there is good wifi connection that takes less than 1s to reconnect. Poor wifi connection is the main reason for battery drain.
+   
+
+* **Calibration values:** 
+
+   These are calibration data for the gyro. Place the device flat on a table and press the button to save the default orientation values. Without this calibration we cannot calculate the correct angle/tilt.
+
+.. warning::
+
+   The device will **not** go into `gravity monitoring` mode unless calibrated

+
+   When enabling SSL this will not validate the root CA of the remote service, this is a design decision based on two aspects. Enabling CA validation will take 3-4s extra on each connection which means way less

+
+* **Gravity format:**
+
+   Gravity format can be eihter `SG` or `Plato`. The device will use SG Internally and convert to Plato when displaying or sending data.
+
+* **Gravity formula:**
+
+   Gravity formula is compatible with standard iSpindle formulas so any existing calculation option can be used. You can also use 
+   the feature to create the formula by supplying the raw data. See :ref:`create-formula`
+
+   The gravity formula accepts to paramaters, **tilt** for the angle or **temp** for temperature (temperature inserted into the formula 
+   will be in celsius). I would recommend to use the formula calculation feature instead since this is much easier.
+
+* **Temperature correct gravity:**
+
+   Will apply a temperature calibration formula to the gravity as a second step after gravity has been calculated. It's also possible to 
+   build this into the gravity formula.
+
+.. warning::
+   This formula assumes that the calibration has been done at 20°C / 68°F.
+
+Formula used in temperature correction.

+
+* **Voltage factor:**
+
+   Factor used to calcualate the battery voltage. If you get a too low/high voltage you can adjust this value.
+
+* **Temperature correction:**
+
+   This value will be added to the temperature reading (negative value will reduce temperature reading). This is applied
+   when the device starts. So changing this will not take affect until the device is restarted.
+
+* **Gyro Temperature:**
+
+   Enable this feature will use the temp sensor i the gyro instead of the DS18B20, the benefit is shorter run time and
+   longer battery life (this is an experimental feature). The value used is the first temperature reading from when the 
+   device is activated, since the gyro should be cool this is reflecting the surronding temperature. After it has 
+   been running the value would be totally off.  
+
+* **OTA URL:**
+
+   Should point to a URL where the firmware.bin file + version.json file are located. 
+
+   For the OTA to work, place the following files (version.json + firmware.bin) at the location that you pointed out in OTA URL. If the version number in the json file is newer than in the 
+   code the update will be done during startup.
+
+   If you have the previx `https://` then the device will use secure transfer without CA validation.
+
+   Example; OTA URL (don't forget trailing dash), the name of the file should be firmware.bin

+Functionallity
+==============
+
+The main features
+-----------------
+
+* **Operates in two modes gravity monitoring and configuration mode**
+
+  In ``gravity monitoring`` mode it behaves just like the iSpindle, it wakes up at regular intervals, measures 
+  angle/tile, temperature, calculates gravity and pushes the data to defined endpoints. 
+
+  In ``configuration mode`` the device is always active and the webserver is active. Here you can view the 
+  angle/tilt values, change configuration options and more. When in this mode you can also interact with the device
+  via an REST API so data can be pushed to the device via scripts (see API section for more information).
+
+  You can force the device into ``configuration mode`` while measuring gravity. This is useful when calibrating 
+  the device so you don't needs to wait for the device to wake up and push the data. The entire calibration
+  sequence can be handled via the web interface without need for additional software tools.
+
+  See the :ref:`setting-up-device` section for more information on how to trigger the configuration mode.
+
+* **Can send data to multiple endpoints at once**
+
+  The original iSpindle can only have one destination, this software will push data to all defined endpoints so 
+  in theory you can use them all. However this will consume more battery power so use only as many as needed. 
+
+  Currently the device supports the following endpoints: http (2 different), influxdb2, Brewfather and MQTT.
+
+  If you want additional targets please raise a feature request in the github repo.
+
+* **Create gravity formulas on the device**
+
+  Another big difference is that this software can create the gravity formula in the device, just enter the 
+  angle/gravity data that you have collected. You will also see a graph simulating how the formula would work. 
+
+.. note::
+
+  This feature needs more testing to be validated.
+
+* **Customize the data format beeing sent to push targets**
+
+  In order to make it easier to support more targets there is a built in format editor that can be used to 
+  customize the data that is to be sent. This way you can easily adapt the software to new targets without coding. 
+  If you have a good template please share it on the girhub repository and I will add it to the documentation 
+  for other users to enjoy. See the :ref:`format-editor` for more information.
+
+.. note::
+
+  This feature needs more testing to be validated.
+
+* **Automatic temperature adjustment of gravity reading**
+
+  If you want to correct gravity based on beer temperature you can do this in the formula but here is a nice 
+  feature that can correct the gravity as a second step making this independant of the formula. 
+
+.. note::
+
+  This feature needs more testing to be validated.
+
+* **OTA support from local webserver**
+
+  When starting up in configuration mode the device will check for a software update from a local webserver. 
+
+* **DS18B20 temperature adjustments**
+
+  You can adjust the temperature reading of the temperature sensor.
+
+* **Gyro Movement**
+
+  The software will detect if the gyro is moving and if this is the case it will go back to sleep for 60seconds. 
+  This way we should avoid faulty measurements.
+
+* **WIFI connection issues**
+
+  The software will not wait indefiently for a wifi connection. If it takes longer than 20 seconds to connect then
+  the device will go into deep sleep for 60 seoncds and then retry.
+
+* **Use gyro temperature sensor**
+
+  This works fine when the device has time to cool down between measurements and it saves up to 400 ms. 
+  My testing shows that this is quite accurate with a deviation of less than 0.3C. This  
+  reduces the run time by 20% (with optimal wifi connection). 
+  
+  The graph below compares from the temp from two different devices in the same bucket of water. One with 
+  gyro temp enabled and one with the DS18B20 sensor. The blue line is the gyro temperature and this clear
+  that the temperature will be higher after it has been running but cools down when in sleep mode. The interval 
+  has been set to 300s. A low delay of 30s will not allow the gyro to cool down and the temperature will 
+  be 0.5-1.0C higher.

+
+Other features
+--------------
+
+* Support for Celcius and Farenheigt as temperature formats.
+
+* Support SG (Plato is not yet supported)
+
+* Gyro data is read 50 times to ensure good accuracy
+
+Experimental features
+---------------------
+
+* **Performance measurements** 
+
+  I've also create a small library to measure execution code in some areas of the code that i know is time consuming. This way I can find a good balance between performace and quality.
+
+  See the :ref:`compiling-the-software` for more information.
+
+* **Power measurements** 
+
+  I've also create a project to measure the power consumption of the device, but more on this later.
+
+
+Battery life
+------------
+
+I'm currently measuring battery life of v0.5 but previous versions have been able to measure gravity for 
+a 2-3 weeks without issues (Using 900 seconds as interval). 
+
+I had a device running with an sleep interval of only 30s with ok wifi connection. The device lasted 
+12 days which i think is excellent considering the short sleep interval. From what I have discovered 
+it's the WIFI connection that has the most impact on the battery life. In a perfect scenario it 
+can take around 400ms but can in some cases take up to 8 seconds. 
+
+*More on this topics once my tests are done*
+
+Performance 
+-----------
+
+Since I have the possibility to measure the performance of different function in the code this is what I have been able to gather.
+
+The typical runtime in a measurement cycle is approx 2 seconds and in some cases it can take up to 6-8 seconds but this is mainly related to establishing the WIFI connection. So stable wifi is 
+essential for long batterylife. Out of the 2 seconds of run-time the major time is spent on gyro readings (1.3s) and temperature measurements of (0.6s) so using the gyro sensor for measureing 
+temperature would reduce the total runtime with 25%. Sending data over http takes less than 100ms (on my local network) so this is not drawing much power. 
+
+The image below shows how the run-time varies over time. The pink line is the wifi connection time and this is why the time varies. The orange is the total runtime for the awake period.
