I am pretty sure that setting the Venstar thermostat mode was previously working but today I noticed that my T7900 was in ‘Auto’ mode when I had set it to ‘off’. Playing around with it a bit this morning, I see that the state as seen in developer tools/states follows exactly the mode selected but the state will always revert to ‘Auto’ after being set to "off.’
I recreated the Venstar integrations which did not solve this problem. The time that elapses from ‘off’ selection to reverting to ‘Auto’ varies and seems to be related to a refresh of the view happening periodically.
The Venstar T7900 thermostat is reporting v9 as the firmware.
