feat: add esp32 Sonoff devices support

docs/12.HardwareSONOFF.md

@@ -0,0 +1,23 @@
+BrewPiLess can run on [SONOFF Basic](https://www.itead.cc/wiki/Sonoff) and [SONOFF TH10/16](https://www.itead.cc/wiki/Sonoff_TH_10/16). You will need to solder the header pins for the first flashing and install temperature sensors. However, because of the small 1M byte flash memory, you will either sacrifice 
+* OTA web update for log storage, or
+* 500k log storage for OTA update
+* LCD is not available.
+
+SONOFF dual is not supported, because the Relays are controlled by Serial instead of GPIO.Instead, SONOFF Dual **R2** should work by specify correct PINs.
+
+Please note that some older SONOFFs, maybe before 2018, use ESP8266 while new ones use ESP8285. Right configuration must be used.
+
+### ESP32 SonOff devices (Sonoff TH Origin and Sonoff TH Elite)
+
+For Sonoff TH Elite the built-in lcd display can be removed and a OLED LCD screen can be connected in it's place.. Use electrical tape to make sure that the LCD pcb is not touching the main pcb. The front glass is a thin plastic be gentle with it. 
+
+#### Conntecting sensor
+The sensor that has the RJ9 connector comes with a controller in the wire that needs to be removed
+Option 1: Remove the controller and reconntect the wires (not tested).
+Option 2: Use  `Sonoff AL010 2.5mm Audio Jack to RJ9 Adapter` with the old sensor using the audio jack conntector.
+
+##### Connecting OLED LCD (optional)
+* Connect SDA to WR solder pad
+* Connect SCL to CS solder pad
+* Use hotglue over soldered contacts so that you don't ripoff the solder pads accidentally. 
+* Connect 3v and Gnd to corresponding solderpads
