 # 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. 
 
-The documenation is now moved to https://mp-se.github.io/gravitymon/index.html
+Now also works with ESP32 (use ESP32 d1 mini which is compatible with ESP8266)
+
+Installation can be made using https://www.brewflasher.com or https://web.brewflasher.com
+
+The documenation can be found here: https://mp-se.github.io/gravitymon/index.html
+
+Note! If Brewflasher being flagged as malware by your antivirus software, try the web version.
+
+The main differences:
+---------------------
+
+* Operates in two modes gravity monitoring and configuration mode
+* Gravity mode is comparable to how the iSpindle works when collectintg data
+* Configuration mode has a modern HTML5 based web UI. No need to start the access point to change settings
+* Offloading some of the functionallity to run in the web browser, this allows for more advanced features.
+* REST API to enable scripted configuration
+* Send data to multiple endpoints and services at once (2xHTTP POST, HTTP GET, MQTT, INFLUXDB2)
+* Directly test all endpoints from user interface with feedback to simplify troubleshooting
+* Complete format customization for all endpoints using templates (dont really need to change the software to support new services)
+* Setup guides for how to send data to many popular services. Currently 10+ are documented
+* Automatic temperature adjustment of gravity (just tick a checkbox)
+* OTA support from webserver
+* Firmware update via web interface
+* Built in function to create gravity formulas, no need for additional software, just enter tilt/gravity and let GravityMon creates a formula
+* Visual graph showing how formula will be interpreted based on entered values
+* Using the temperature sensor in gyro instead of DS18B20 (faster)
+* SSL support in all endpoints (no certificate validation due to limitations on esp8266).
+* Built in performance measurements (used to optimise code)
+* Storage mode when placed on cap (indefinite sleep)
+* Customize various hardware parameters to opimize device functionallity.
+* 
+No code has been reused from the iSpindle project.

+Copyright (c) 2007, Jim Studt  (original old version - many contributors since)
+
+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.
+

+  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.

+
+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

+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. 
+
+You can also select a template from the list and copy that to the current endpoint. 
+
+Saving an empty formula will reset it to the default value.
+
+.. tip::
+
+   If you save a blank string the default template will be loaded.
+
+These are the format keys available for use in the format.

 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.

+If the sleep interval is 300s and MQTT is set to 0 and HTTP1 is set to 2 then MQTT will be sent every 300s while HTTP1 would be sent 900s. This is great if you want to send data to a local mqtt server often but brewfather will only 
+accept data every 15 min.

 Contributing
+############
+
+Anyone is welcome to contribute to this project or create their own variant of it. I would appreciate a PR if your feature would be of benefit other users. 
+
+In order to keep the source code in good condition I use `pre-commit <https://pre-commit.com/>`_ to validate and format the code using their standards for C++/C. 
+
+.. note::  
+
+  If you are using Windows as a base platform I would suggest that you install pre-commit under wsl (Windows Subssytem for Windows) and run it from there, I have found 
+  that this approach works fine. 
+
+
+The following command will run pre-commit on all the source files. Assuming you are inte project directory.

+Design goals
 ------------
 
-This section is under construction.
+My goals with this software has been the following:
 
+* Create an open software for the excellent iSpindle hardware platform that is open and available for anyone. 
+* Add user requested features that have not made it into the iSpindle project. 
+* Focus on long battery life and stability.
+* Explore new technologies and create the next generation gravity monitoring for home brewers. 
+
+I will do my best to assist users and respond to new features, pr and suggestions. But keep in mind I'm doing this on my spare time.

+When you submit the values the device will try create a forumla with increasing level of complexity. It will start

+This means that the angle 33.43 had a deviation of 5.8 SG and since the default threashold is 3, it will fail. You 
+can also see that it has failed on that point in both a order 2 and 4 formula.

+use the graph on the calibration page to identify angles that is probably not correct.

   sequence can be handled via the web interface without need for additional software tools.

-* **Build in function to create gravity formulas, so no need for using other tools for this part**
 
-  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. 
+  Under the :ref:`services` section you can find guides for how to connect GravityMon to these services. For a 
+  description of what data is transmitted you can see :ref:`data-formats`. 
+  
+  The software support SSL endpoints but currently without CA validation, this means that the data is encrypted 
+  but it does not validate if the remote endpoint is who it claims to be. 
 
-* **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. 
+  if you require CA validation please leave a comment on GitHub and I will make that a priority. Adding this function
+  will dramatically reduce the battery life of the device.
 
 .. note::
 
-  This feature needs more testing to be validated.
+  Using SSL on a small device such as the esp8266 can be unstable since it requires a lot of RAM to work. And running out
+  of RAM will cause the device to crash. So enable SSL with caution and only when you really need it. GravityMon will try
+  to minimize the needed RAM but the remote service might not support that feature.
 
-* **OTA support from local webserver**
+* **Create gravity formulas on the device**
 
-  When starting up in configuration mode the device will check for a software update from a local webserver. 
+  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. 
+
+  Currently the device can handle 10 data points which should be enough to get a accurate formula. At least 3 data points 
+  is needed to get an accurate formula.
+
+* **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 github repository and I will add it to the documentation 
+  for other users to enjoy. See the :ref:`format-editor` for more information. See :ref:`services` for a list of
+  services currently validated.

+  When starting up in configuration mode the device will check for a software update from a webserver. This is an easily
+  way to keep the software up to date. In the future I might add a hosted endpoint for providing updates. OTA can also be 
+  done over a SSL connection.

 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). 
+The long term battery test has now been completed. Using a 2200 mA battery and sending data every 5 minutes to a local server on my network. The battery lasted 47 days which is excellet battery life. 
 
-*More on this topics once my tests are done*
+In another test 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 or latency to internet hosted that has the most impact on the battery life. The typical runtime in the tests above was around 2 seconds.

+Hardware

+
+There are lots of resouces out there on how to build the hardware for an iSpindle so I will not go into details on that part. Here are two of my builds using the iSpindle PCB v4.
+
+.. image:: images/ispindel.jpg
+  :width: 500
+  :alt: Builds of iSpindel
+
+It's possible to use this PCB and mount an ESP32 on top of that. It must be an pin compatible ESP32 and the one I used was called *ESP32 d1 mini*. Since this is the same width as the PCB you need to 
+mount it really close to the PCB in order for it to fit in the PET tube/container. I also had to smooth the edge of the ESP32 in order for it to fit. 
+
+I would suggest that you try how it fits into the PET tube before soldering it to the PCB. Make sure that the battery is attached since this will be a really tight fit.
+
+You also need to desolder (remove) the RED ON LED from the ESP32 or the battery power will be reduced a lot.
+
+Final thing is to add a resistor between A0 (Analog PIN) and ground of 470k. The reason is that the esp8266 has a build in resistor which 
+the esp32 does not have. So in order to get a valid voltage (less than 3.2V) on the A0 pin this is needed. Once the modification is done you might
+need to adjust the voltage factor so the battery reading is correct.

+----------------------
+
+.. note::  
+  This schema assumes that an ESP32 D1 Mini (pin compatible with ESP8266 D1 Mini is used)
+  The ESP32 has two rows of pins but only the inner row is used. The main difference is the added resistor R3 so we 
+  get a voltage divider for measuring battery. The ESP8266 has a built in resistor thats not visible on the schema.

+A reed switch is a switch that reacts to magnetic fields. The ones I have tested are normally open and close in proximity to 
+a magnet.

+If this is connected to the reset button a magnet can be used to trigger a reset of the device. The image below shows how 
+I mounted the iSPINDLE PCB v4.0 just under the cap. The lower red circle shows the reset connection point for the reed switch.
