Mitsubishi Comfort Integration Has No Entities

I have a Mitsubishi cold-climate heat pump, model #PUZHA42NKA1, a Mitsubishi ducted air-handler, model #PVAA42AA7, and an MHK2 thermostat with wireless control. I have an Alexa skill that can control my thermostat just fine, and, in fact, I can call Alexa routines from HA to do just that.

However, I added the Mitsubishi Comfort integration to my HA instance, and it added just fine and linked to my Kumo Cloud account, but the integration shows no entities, so I have nothing to control. Has anyone seen this problem?

Hi David, is all this correct:

Yes, all of this is correct!

Did you check your logs:

Open your Home Assistant instance and show your Home Assistant logs.

If nothing is in there, you could try by removing the integration, restarting HA and adding it again…
