I have three CentraLite HA thermostats. The one in the garage is heat only. The two in the house have heating and cooling. The one I have assigned upstairs will not show a cool button on the thermostat card. If I change the card to the downstairs thermostat, I get all three buttons (Heat, Cool, Off). I think this may be because when I first added the thermostat, I had it set to heat only. I tried removing the thermostat and re-adding it but the problem remains. I can set the thermostat to cool on the thermostat front panel but not through an automation. Thanks for any help. I’m pretty new at this.
I think I have it resolved. I removed it again and added it using a different name and the cooling button came up. I don’t think I changed anything else. I was then able to change the name back to the original name (Upstairs) and everything still works. Good enough.
