Thread from ST forum - there was an update in 2019, at least, doesn't sound like it would address the issues discussed here.
Instructions to update (assuming you have access to a ST hub). I had these in some notes I'd saved, no idea if below works or not...
Aha! Discovered the instructions were from @dJOS - so we know he's already applied the update. His post here:
- Take your Zen off the wall, wake up the screen if it isnt already on.
- Press the network button 10 times to remove it from your HE Zigbee network - this is only done on the device, your HE device won't be removed unless you run that process on the HE (so dont).
- On your SmartThings app, select add a device and pick the Zen Thermostat
- Press the network button 5 times to add it to your SmartThings
- follow the instruction HERE to check your Device FW version
a. Take your Zen off the mount
b. Select "prefs"
c. Scroll right to "info" and the first item when you scroll down is your current FW version. - pull the batteries out of your Zen for a minute
- Wait for up to 10 mins and it should auto-update - you'll know it's doing this as a symbol will start randomly flashing around the screen. It's done when the display goes back to showing "prefs".
- make sure the Zen is responding in the ST app then power down your ST HUB
- Press the network button 10 times to remove it from SmartThings
- On your Hubitat Hub, go to discover Zigbee new device and start the discovery process
- Press the network button 5 times to re-add it to your Hubitat - you'll see it say something along the lines of "found an existing device". This means you succeeded!
