 # Gravity Monitor for Beer Brewing
 
-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. 
+![GravityMon Logo](src_docs/source/images/gravitymon_logo_s.png)
 
-Now also works with ESP32, either an ESP32 d1 mini or ESP32 c3 mini which both are compatible with ESP8266.
+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.  
 
-Installation can be made using https://www.brewflasher.com or https://web.brewflasher.com
+Now also works with ESP32 d1 mini, ESP32 c3 mini, ESP32 S2 mini which both are pin compatible with ESP8266.
 
-The documenation can be found here: https://mp-se.github.io/gravitymon/index.html
+Installation can be made using https://www.brewflasher.com or the web version at https://web.brewflasher.com
 
-Note! If Brewflasher being flagged as malware by your antivirus software, try the web version.
+The documentation can be found here: https://www.gravitymon.com/docs.html
 
-The main differences:
----------------------
+Visit the gravitymon homepage here for more information about the project: https://www.gravitymon.com
 
-* 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.

+# 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.

+Serial debugging on battery
+===========================

+  :alt: Serial output
+
+On the ESP32 builds the serial output can be  written to UART0 which is connected to the RX/TX pins on the chip. This way the serial output can be viewed 
+without a connection to the USB port, convinient when running the device on battery power. In order to get this to work you need to compile the sofware 
+with the option **DUSE_SERIAL_PINS** and attach as USB to TTL cable to the correct pins. 
+
+You connect the USB to TTL cable that you connect the TX, RX and GND pins. **Dont connect the power pin** if you are powering the device from USB or Battery.

 Battery life
 ------------
 
-The long term battery test has now been completed. Using a 2200 mA battery and sending data every 5 minutes to a local server on my network. The battery lasted 47 days which is excellent battery life. 
+For the 1.2 version I have been running some long term battery tests on a few of the boards and also comparing wifi vs Bluetooth. I was using a standard 2200 mA battery 
+that was fully charged at the start of the tests. All devices started with factory settings with only a change in push destination and sleep interval. 
 
-In another test I had a device running with an sleep interval of only 30s with ok wifi connection. The device lasted 12 days which i think is excellent considering the short sleep interval. 
+For the wifi tests, I was pushing data every 30 seconds to a local influxdb2 server to reduce errors connected to slow response on the server side. The devices 
+was placed 2 meters from the wifi AP to ensure a good and stable wifi connection (so ideal conditions). 
 
-From what I have discovered it's the WIFI connection or latency to internet hosted that has the most impact on the battery life. The typical runtime in the tests above was around 2 seconds. 
+For the Bluetooth tests I was pusing data every 10 seconds to a linux server. 
 
+To make this comparable I measured how many times the device was able to wake up and push data before the battery was dead. I theory the power consumption when in 
+deep sleep is to low it can almost be ignored for the calculations. So the impact on battery is mainly caused by how long the device is awake. In the most optimal case 
+this can be as low as 1.5-2.0 seconds but in reality its probably around 3-4 seconds. Wifi consumes a lot of power so Bluetooth is a better option for long battery life.

+this hardware platform as well but there are a few limitations:
+

+
+
+Hardware extensions
+===================
+
+GravityMon has implemented a few additions to the standard iSpindel hardware. It's possible to channel the serial console to the TX/RX pins on the chip (these position also applies to all the 
+ESP32 chips for iSpindel). You need a USB to TTL converter for this to work. This enables you to read the serial console even when on battery (newer chips dont have a diode to remove).
+
+.. note::
+  You need to compile the software using the -DUSE_SERIAL_PINS option to enable this feature.
