It runs off the P1 P2 com or the S1 which unfortunately just shows functionality on the DKN software. So far, only the Daikin D-checker software can show the breakdown of everything going on in the system but only with P1 P2 capable units.
You would probably have to get into Modbus to get that out but I’m not sure. I ended up just getting a zwave disconnect with power monitoring for the outdoor unit.
I was able to get the gpulido/homeassistant-airzone HACS integration to work with my new Daikin unit with the AZAI6WSCDKC module.
It works pretty well with local control. The github hasn’t been updated in about a year, not a lot of support but as long as it continues to work, I’m happy.
I do see that the DKN Plus NA App has more information than the integration (or even the API via the local IP) provides. One of the missing items is the external temperature.
