:alt: User Inteface Walkthrough
GravityMon is used to measure gravity and temperature during fermentation of beer and report the progress. The graph below is
an example on how the fermentation process can be tracked. This is from my last brew that was over on a few days. The graph is rendered using
Fermentrack.

GravityMon is a replacement firmware for the iSpindle and uses the same hardware configuration and is 100% compatible. It
implements a lot of the features that has been requested in the orginal iSpindle project but has been rejected for
implements a lot of the features that has been requested in the orginal iSpindle project but never implemented for
various reasons. Here is a list of :ref:`main_features`.
From v0.9 the firmware now supports a iSpindle build based on an ESP32 d1 mini (pin compatible with esp8266). See :ref:`hardware`.
From v0.9 the firmware also supports a iSpindle built using an ESP32 d1 mini (pin compatible with esp8266). Currently this is an experimental
version but since it has more memory and processing capacity it could support more functions. See :ref:`hardware`.
I started GravityMon because I like to create software and wanted to do some low level programming. I had done a few
I started GravityMon because I like to create software and wanted to do some microcontroller programming. I had done a few
projects based on esp8266 and also started to brew beer so this combination was quite natural.
The hardware design comes from the fantastic iSpindle project so that is not covered in this documentation. For more
information on this topic and function please visit `iSpindel Homepage <https://www.ispindel.de>`_ .
My approach to this software is a little different from that the original iSpindle firmware. The github repository
can be found here; `GravityMon on Github <https://github.com/mp-se/gravitymon>`_

.. note::
I dont take responsibility for any errors or issues caused by the software. The software is provided as-is. I will however
try my best to fix issues that might occur.
I have tested this software over the last year on 20+ brews with good results.
I have tested this software on 40+ brews with good results.

Main features:
--------------
* Operates in two modes gravity monitoring and configuration mode (simplify calibration). Gravity mode
is comparable to how the iSpindle works.
* Modern web based UI when in configuration mode. No need to start the access point changing settings.
* 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
* Directly test all endpoints from user interface to simplify troubleshooting
* Complete format customization for all endpoints using templates
* Setup guides for how to send data to many popular services. Currently 8+ are documented.
* Automatic temperature adjustment of gravity reading
* 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 create the formula.
* 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 standard HTTP and MQTT connections.
* 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.
For a complete breakdown see the :ref:`functionallity`

This is a simple overview of the different components that the software contains. The green ones are only active during `configuration mode` in
order to save battery.
