For those of us not using HomeAssistant, I’m using openHAB, I have set-up a Mosquitto broker which the Currently One now is sending topics to every 5s.
I can see this being reported:

currently/one/d0dd1e79cf58/state {"m":"HAN","W":1464,"Wh":801211,"t":"2024-02-03T16:12:10+0100","Ph":0,"Rh":197394,"Qh":11427,"P":0,"R":0,"Q":201,"L1":346,"P1":0,"R1":0,"Q1":178,"I1":1.900,"U1":233.600,"L2":1106,"P2":0,"R2":17,"Q2":0,"I2":4.900,"U2":231.400,"L3":11,"P3":0,"R3":0,"Q3":39,"I3":0.100,"U3":231.700,"sec":1706973130}

Is there an explanation to these values anywhere?

  • L1
  • P1
  • R1
  • Q1
  • I1

etc.
and also how they are related.

My plan is then to integrate Currently One to openHAB using openHABs MQTT binding.
FLASH: There seems to be an integration towards HomeAsistant MQTT in openHAB:

That integration works great in openHAB:

Hej Janne,
du borde kunna hitta infon på MQTT protocol / API, om du saknar någon info får vi bättra på den topic:en!

Hälsningar
Ola på Currently

RTFM :slight_smile:

Sorry, hur kunde jag missa det.
Tack för en grym produkt! :slight_smile:
