When arming the system from my phone or alarm.com there is usually a slight maybe 6 second delay before the panel activates, but the status is kept up to date on both alarm.com and the app.
I’ll have to test the thermostat specifically and get back to you.
The lack of update is both on the app and alarm.com webpage. Once the webpage shows the correct status, the app follows suit. There is no issue sending the zwave commands to lock or unlock the doors and if I send the command through alarm.com or the app it updates the status. It seems like it’s when I use the touch pad on the door, or the manual thumb turn that the status doesn’t update on alarm.com or the app.
