@JasonJoel I just looked at 1 of my thermostats. Batteries are dead again. This was within 4 days
Just FYI, hubitat release 2.0.9 has a built-in driver for this thermostat. May be worth trying to see if it helps your battery issues.
Also, another thing to check is on the thermostat itself, go into the Menu --> Info and see if it thinks it is in battery mode or AC power mode (have to down arrow a few times to get to that entry).
It probably wont, the built in driver uses the default report settings.
I see they just released the new update. I will give that a try
Should I first remove the custom driver then update? How do I go about getting the thermostats on the new driver?
Definitely double check the menu --> info to see if it thinks it is battery powered or AC powered. Also, may double check your backlight settings while in there - too much use of backlight zaps battery on this model, too.
If for some reason it is in AC Power mode, the only way I know to change it is to unpair it from the zwave network, factory reset the thermostat from the menu, and then re-pair it to the zwave network.
I looked at my Menu-->info I don't see anything about AC power or battery.
You know that's interesting. There's no reference to that in the manual either. But on all four of my thermostats if I go into menu and then info and then up arrow the first thing it says is AC powered.
When I hold the Fan Button to get into the Menu, Click the up arrow, the first thing that pops up is Battery 66%. Do you have a C wire on yours?
Yes, all of mine are cwire powered.
But I meant hold fan until you get in the menu, up/down arrow until info, select, then up arrow. That's where I see ac powered. Not sure what it looks like on battery powered devices, though.
But if yours does not say ac-powered there, that's probably a good thing.
I think your's says AC power because you do in fact have it on AC power. Since I don't have this, my only says battery
Yeah, so I guess that is good. I've seen a number of thermostats get stuck in "ac power" mode, even if on battery - and that destroys battery life as it acts as a zwave repeater.
I'm out of suggestions. 
So I haven't upgraded to the new version of Hubitat yet. Should I remove my Thermostat from Hubitat first, Uninstall the customer driver. UPDATE Hubitat and re-pair the thermostat?
No real need to un-pair/re-pair if it is already in battery mode (which it looks like it is). You obviously CAN un/re-pair, but there isn't a specific need to.
Since it appears to be paired correctly, you can switch drivers as you see fit at any time. Just remember to set/save the Parameters, wait a few seconds, then hit configure.
In 2.0.9 the new in-box driver is named "GoControl Z-Wave Thermostat".
I'm not optimistic this is going to fix your issue. But here's hoping it does. If it doesn't, then maybe un-pair/re-pair under version 2.0.9.
Should I remove the customer driver before upgrading to new version? Or will Hubitat just use the new driver? Or... is this driver something I can choose?
It only changes driver on pairing, or when a user tells it to/selects a new driver in the device details (just like you should have done when switching to my user driver - if you didn't you were never using my driver at all...).
Got it. So under the device, I choose TYPE: Enhanced GoControl GC-TBZ48 right now. I should be able to change this from here with the new version?
Correct. So after upgrading to 2.0.9, you could:
- Go to device details of the thermostat
- Change driver type to "GoControl Z-Wave Thermostat"
- Click the Save Device button
- After screen refreshes, configure Preferences as desired
- Click Save Preferences
- Wait 30 seconds to allow time for the preferences to save (doesn't actually take that long on the stock drivers, as there are only a couple of preferences to save - it takes much longer on my user driver as there are a lot of parameters to save).
- Click the "Configure" command button
Got it now...Thanks
I'm thinking about replacing my current thermostat with a GC-TBZ48. What is the smallest calibration setting (i.e. Is it by whole degrees F or by .5)?
