 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. 
 
-Now also works with ESP32 (use ESP32 d1 mini which is compatible with ESP8266)
+Now also works with ESP32, either an ESP32 d1 mini or ESP32 c3 mini which both are compatible with ESP8266.
 
 Installation can be made using https://www.brewflasher.com or https://web.brewflasher.com

 The main differences:
 ---------------------
 
-* Modern web based user interface for configuration when connected to WIFI
+* Operates in two modes gravity monitoring and configuration mode
-* Efficient software, long lifespan (+45 days with 5min update frequencey)
+* Gravity mode is comparable to how the iSpindle works when collectintg data
-* Send data to multiple endpoints (http-post, http-get, influxdb v2, mqtt)
+* Configuration mode has a modern HTML5 based web UI. No need to start the access point to change settings
-* Instructions for service such as; Brewfather, Fermentrack, Ubidots, Home Assistant, Brewers Friend, Brewspy, Thingspeak, Blynk. 
+* Offloading some of the functionallity to run in the web browser, this allows for more advanced features.
-* SSL support for all remote endpoints
+* REST API to enable scripted configuration
-* ESP32 support with Bluetooth push
+* Send data to multiple endpoints and services at once (2xHTTP POST, HTTP GET, MQTT, INFLUXDB2)
-* Customize data format to be pushed
+* Directly test all endpoints from user interface with feedback to simplify troubleshooting
-* Automatic temperature adjustment of gravity when enabled
+* Complete format customization for all endpoints using templates (dont really need to change the software to support new services)
-* Use the temperature sensor in gyro instead of DS18B20
+* Setup guides for how to send data to many popular services. Currently 10+ are documented
-* Built in function to create gravity formulas, no need for additional software, just enter tilt/gravity. 
+* Automatic temperature adjustment of gravity (just tick a checkbox)
-* Visual graph showing how gravity formula will be interpreted
+* OTA support from webserver
-* OTA support or firmware upload via web interface
+* Firmware update via web interface
-* REST API for scripting
+* 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.

-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.

-* (beta2) Changes length of device name from 12 to 63 chars. 63 is the max limit according to mdns. 
 
 Features
 ++++++++
-* Added storage mode which is activated under hardware setting. When place on the cap (<5 degres tilt) the device will go into storage mode and sleep for the max allowed time. 
+* Added support for the ESP32 C3 mini board
-* Added ${app-ver} and ${app-build} to format template as new variables.
+* Serial output is written to TX/RX pins instead of the USB connection for the ESP32c3. This way the serial console can be viewed when running on battery power.
-* Added format templates for HA auto registration
+
-* (beta2) Improved error messages when creating formula so the meaasurement points can be identified.
+Issues adressed
-* (beta2) Changed defaule validation threashold from 1.6 SG to 3.0 SG, this should allow for some more variance when creating formula.

+Features
+++++++++
+* Added information to error log about abnormal resets (for instance crashes) to detect and fix those
+* Changed storage mode so that the device will go into deep sleep until reset (sleep forever)
+* Updated sensor types in home assistant for auto registration of device
+* Added ${app-ver} and ${app-build} to format template as new variables

+
+Known issues, not yet fixed
++++++++++++++++++++++++++++
+* When updating firmware and the feature `deep sleep` is active the device will activate deep sleep if the gyro is not responding. FIX: Reboot device
+
+Issues addressed
+++++++++++++++++
+* Refactored error logging function to reduce memory usage and crashes. Max size of error log is 2 x 4 kb
+* Refactored format template engine to reduce memory usage and crashes, can how handle slightly larger payloads than before. Increase from around 1100 chars to 1600 chars
+* BUG: Refactored format api to handle larger payloads
+* BUG: After manual firmware upload the device would crash and go into wifi setup mode.
+* BUG: After manual firmware upload the device will in some cases not be able to connect with the gyro, the symptom is that it will say, "Gyro moving" in the web UI. In this case the device needs to be reset (or powered on/off). I havent found a way to fix this from the code. The message after firmware update has been updated with this information
+* BUG: Temp corrected gravity was not used when pushing data to removed
+* BUG: Low memory in format api which resulted in mqtt template to be set to null
+* BUG: Large format templates could be saved but when loading it's only blank
+* BUG: Copy format templates used an old format for iSpindle and Gravmon where the token was not used
+* BUG: Gravity correction formula not calculating correctly
+
+User interface
+++++++++++++++
+* Updated format template with information on size and warning message if the template is too large
+* Added error message if gyro connection/initialization fails (before the message was Gyro Moving only)
+* Added error message if no temp sensor can be found
+* Added drop down menus in user interface to simplify navigation to sub pages (format, test and upload)
+* Added Assistant Device registration, this is only done when format template is saved, during normal operation only data values are posted on MQTT. If HA is restarted then the device will disappear
+* Calibration temperature (for temp adjustment) can now be set under advanced settings, default is 20C
+* Changed length of device name from 12 to 63 chars. 63 is the max limit according to mdns.
+* Under format options its now possible to select brewfather iSpindle format to avoid errors connected to using the wrong format template with the various brewfather endpoints
+* Added brewblox as format under format options
+* Added home assistant (with device registration) as format under format options
+* User can now edit the voltage level that forces the device into config mode (device detects charging)
