 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.

 The main differences:
 ---------------------
 
-* Modern web based user interface for configuration when connected to WIFI
-* Efficient software, long lifespan (+45 days with 5min update frequencey)
-* Send data to multiple endpoints (http-post, http-get, influxdb v2, mqtt)
-* Instructions for service such as; Brewfather, Fermentrack, Ubidots, Home Assistant, Brewers Friend, Brewspy, Thingspeak, Blynk. 
-* SSL support for all remote endpoints
-* ESP32 support with Bluetooth push
-* Customize data format to be pushed
-* Automatic temperature adjustment of gravity when enabled
-* Use the temperature sensor in gyro instead of DS18B20
-* Built in function to create gravity formulas, no need for additional software, just enter tilt/gravity. 
-* Visual graph showing how gravity formula will be interpreted
-* OTA support or firmware upload via web interface
-* REST API for scripting
-
+* 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.

-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

+Work in progress...
+
+ESP32 d1 mini
++++++++++++++
+
+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.

 Schema for esp32 build
-----------------------
+++++++++++++++++++++++
 
 .. 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.

+Adding a reed (magnetic) reset switch
+=====================================
+
+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.
+
+The reed switch is the glass tube visible under the esp8266.
