Unable to change temperature via Ring App for Honeywell T6 Z wave thermostat

Hi,
I recently included Honeywell T6 Z wave thermostat to Ring system. However, I am unable to increase/decrease temperature from Ring app on the iPhone. Pressing the up/down button does not have any effect. Anybody faced this?

HI @user3295. Have you tried removing the Honeywell thermostat and relinking it in the Ring App? If you haven’t already, I’d recommend giving this troubleshooting step a try and then testing the controls in the Ring App. Make sure your Ring App and phone’s OS are fully updated as well.
