 # 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
+Installation can be made using https://www.brewflasher.com
+
+The main differences:
+---------------------
+
+* 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.
+
+No code has been reused from the iSpindle project. 
+
+The documenation can be found here: https://mp-se.github.io/gravitymon/index.html

+
+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

+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.

+
+* SSL support for HTTP targets
+* SSL support for MQTT targets
+* SSL support for OTA
+* Added support for Plato
+* Added error handling for calibration page.
+* Added experimental target ESP32 (using an ESP32 D1 Mini which is pin compatible with ESP8266). Not 
+  really usable since wifi connection is extreamly slow with current Arduino releases (3-8 seconds).
+* Added experimental format editor so users can customize their data format used for pushing data. 
+  This will reduce the need for custom push targets. As long as the service is supporting http 
+  or https then the data format can be customized.
+* Added check so that pushing data is not done if memory is low (this will avoid crashes)
+* MQTT topic has been removed from config (handled via format templates)
+* MQTT port port number added. Port over 8000 will activate SSL.
+
+* **Breaking change**: To simplify the internal structure the 
+  temp sensor adjustment is now stored in C. So if you have 
+  enabled this function using F you will need to go into 
+  the configuration and update the adjustment factor again (hardware config).

+This chapter contains a list of targets and what configuration is needed to interact with them.
+
+Brewfather
+++++++++++
+
+Brewfather is an all in one service that allows you to manage you recepies and brews. 
+
+Just enter the http adress found on brewfather, not other settings are needed. The endpoint has the following format:
+
+.. code-block::
+
+   http://log.brewfather.net/http://log.brewfather.net/stream?id=<yourid>
+
+
+The URL is found under settings.
+
+Fermentrack
++++++++++++
+
+`Fermentrack <https://www.fermentrack.com>`_ is a open source brewing software to monitor and control fermentation.
+
+GravityMon can be installed and used as an iSpindle. Just register the device as an iSpindle and use the defined endpoint which normally is:
+
+.. code-block::
+
+   http://myservername/ispindel
+
+
+UBIdots
++++++++
+
+`UBIdots <https://www.ubidots.com>`_ is a IoT service that display data collected various sources. 
+
+For this service there are two options to configure the integration. First you will need your default token which is found under `API Credentials` (<api-tokem> in the example below).
+Swap the text <devicename> with the name you want to show in ubidots. 
+
+**Option 1** - token as an URL parameter
+
+Enter the following as URL:
+
+.. code-block::
+
+   http://industrial.api.ubidots.com/api/v1.6/devices/<devicename>/?token=<api-token>
+
+
+Even though ubidots can handle the default ispindle format it probably better to just post the data you want. This is an example of a 
+format template that can be used. For information on customizing the format see :ref:`format-editor`.

+
+Home Assistant
++++++++++++++++
+
+`HomeAssistant <https://www.homeassistant.com>`_ is a platform for home automation and can collect sensor data
+from multiple devices. 
+
+This setup uses the MQTT integration with home assistant to collect values from the device.
+
+This part of the configuration goes into the home assistant configuration.yaml file. The example assumes that the
+device is named `gravmon2`
+
+::
+
+   sensor:
+   - platform: mqtt

+   - platform: mqtt
+      name: "gravmon2_rssi"
+      state_topic: "gravmon/gravmon2/rssi"
+
+
+Enter the name of the MQTT server in Home Assistant in the URL. You might need to install that option 
+first. This is the format needed to submit the data to the correct topics as needed above. You can add as 
+many sensors / topics as you want.
