Configuration
{"NAME":"Smarteefi NS11","GPIO":[2624,0,0,0,160,2720,0,0,0,2656,224,0,288,0],"FLAG":0,"BASE":18}
For more accurate energy consumption measurements this device requires power monitoring calibration.
- It is possible to make a backup copy of the stock firmware with esptool.py
- Soldering a small wire to the GPIO 0 which is easily accessible next to the switch connector ensures easy flash mode by shorting to ground
- power the module from 3.3v only. DO NOT CONNECT TO MAINS WHEN FLASHING / WORKING on the board
- can use Webserial to flash tasmota
- Requires power calibration after setup
