Hi all, i would like to add to my “growing” openhab2.0 installation a few of this little (and cheap) devices in order to create a basic energy monitoring system capable of avoid power outage.
After reading here and there i ended buying 4 S20 Smart Socket (that i will connect to my dryer, washing machine …) and 2 Sonoff Pow (in order to check the total power absorbed on plug and light lines).
Before i start to patch the SonOff devices i’m still a little bit confused on the steps i need to follow in order to install the Arendst firmware: as far as i could understand i need only to temporarily solder the USB-TTL wires to the Sonoff board, like for the “basic” sonoff. Is it right or i need to do something else?
I’m asking this because all the documentation i found on the net always refer to the “basic” sonoff device, not the smart plugs or the POW.
Thanks in advance
