 # 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 Logo](src_docs/source/images/gravitymon_logo_s.png)
 
-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. 
+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. From v1.2 you can also use GravityMon for the DIY Floaty Hardware with ESP32 Lite.  
 
-After 6 months of testing I believe this is working as planned. It give accurate readings same as the orginal iSpindel software. 
+Now also works with ESP32 d1 mini, ESP32 c3 mini, ESP32 S2 mini which both are pin compatible with ESP8266.
 
-Version history
-* v0.4 First official version with 5+ brews on record. 
+Installation can be made using https://www.brewflasher.com or the web version at https://web.brewflasher.com
 
-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.
+The documentation can be found here: https://www.gravitymon.com/docs.html
 
-# Functionallity
+Visit the gravitymon homepage here for more information about the project: https://www.gravitymon.com
 
-I have made a few different design decision compared to the standard iSpindle software. 
+If you want to support my work you can do that through these options
 
-* 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). 
+[<img src="https://gravitymon.com/images/buymecoffee.png" height=40>](https://www.buymeacoffee.com/mpse/) [<img src="https://img.shields.io/static/v1?label=Sponsor&message=%E2%9D%A4&logo=GitHub&color=%23fe8e86" height=40>](https://github.com/sponsors/mp-se)
 
-* 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. 
+# Supporters
 
-* 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.
+Thanks to the following persons for supporting me and this project:
 
-* 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

-```
-
-![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

-# 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.

+# Unit testing - Python Script
+
+I have moved my test scripts into this project now. They are mainly based on python scrips and validate the features from the API's.
+
+Create a virtual environment and install the needed dependecies
+```
+python -m venv .env
+pip install -r requirements.txt
+```
+
+Before you runt the script you need to update the IP adress to match the device that you have on your network.
+
+Running the ALL tests
+```
+cd src/test
+python3 -m unittest -v apitests.py -v

+
+Running the ONE test
+```
+cd src/test
+python3 -m unittest -v apitests.API.test_status -v
+```
+
+# Unit testing - Specific build
+
+I've added a specific build that uses the AUnit (https://github.com/bxparks/AUnit) testing framework so that we can test functions or classes on the device itself. I hope this will simplify the release and testing cycle.
+
+1. Select the build target (gravity-unit)
+2. Build/upload the code to an iSpindle device. 
+3. Check the output from the serial console.

+
+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.

+
+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
+-- Tom Pollard, Jan 23, 2008
+
+Jim Studt's original library was modified by Josh Larios.
