Hello,
I created a first app, just as a fun project. It reads the homewizard P1 values and publishes them over the network by multicasting UDP packets that mimic an SMA Energy Meter. That way, my SMA Inverter webpage can show me also how much energy the house is using, without having to buy a real SMA Energy Meter.
Check it out here: GitHub - metalMajor/com.metalmajor.p1sma: Homey App to convert P1 meter values to SMA Energy Meter
Let me know what you think, any tips/tricks/issues/improvements are most welcome!
Bye
