I’m running OH 1.83 on a Raspi with a Tellstick to read all the temperatures and control the switches in my house. Now I bought an efergy e2 ir wireless electricity monitor to read the pulses from my energy meter. To get the energy readings into my raspi I bought a DVB-T USB dongle with SDR support. I added RTL-SDR together with a decoder (RPI_Efergy) to read the energy data which will be send every 30 s. This value for the moment will be written into a text file. It looks like this:
Efergy Energy Monitor Decoder
Now my question, what will be the easiest way to get the energy value, in this case 1.079 kW, into openhab and show it as a live value and add as a persistence ???
Thanks for any advice.
