I have a multistage heat pump controlled by an ecobee Premium thermostat integrated via HomeKit. My heat pump has 2 stages of heating and cooling, plus electric heating strips when it’s extremely cold.
On the thermostat I can see the stage and if the electric heat is running. I want to see that in the HA thermostat card also.
I’ve looked at HomeKit docs in the past and I don’t think the thermostat accessory supports this, but wanted to file the request just in case.
