 # 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)
 
-The documenation is now moved to https://mp-se.github.io/gravitymon/index.html
+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.  
+
+Now also works with ESP32 d1 mini, ESP32 c3 mini, ESP32 S2 mini which both are pin compatible with ESP8266.
+
+Installation can be made using https://www.brewflasher.com or the web version at https://web.brewflasher.com
+
+The documentation can be found here: https://www.gravitymon.com/docs.html

+# 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.

+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.
+
+Version 2.3:
+  Unknown chip fallback mode, Roger Clark
+  Teensy-LC compatibility, Paul Stoffregen
+  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
+  Improve reset timing, Mark Tillotson
+  Add const qualifiers, Bertrik Sikken
+  Add initial value input to crc16, Bertrik Sikken
+  Add target_search() function, Scott Roberts
+
+Version 2.1:
+  Arduino 1.0 compatibility, Paul Stoffregen
+  Improve temperature example, Paul Stoffregen
+  DS250x_PROM example, Guillermo Lovato
+  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
+-- Tom Pollard, Jan 23, 2008
+
+Jim Studt's original library was modified by Josh Larios.

+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::
+
+   If format templates are large this feature can be 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 formula 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.
