Thanks! It the thermostats we use


Awesome.. Was beginning to wonder if anyone else used this device :rofl: :partying_face:


We got our off EBay open brand new open box for 60 last month.

Still running great for us.

Nice.. I got one off ebay for $80 and another off amazon for $120 if I remember correctly


I have the external temperature probe coming in monday.. So I will most likely have another update then..


The driver works great! As a test, I changed several parameters - everything worked. The only thing that I'm not sure worked is setting the time.

It does.. It is automated and runs periodically to catch clock drift.. It syncs with hubitat time


I’m excited to see what I can do with the outdoor temperature probe..

Yeah - I might get my AC guy to install that later this year. Right now I'm using Darksky to get the outdoor temperature to control my thermostat (switch between heat/cool mode). Darksky is going away in 2021. So this seems like a good idea!

The only thing I couldn’t get it to do automatically.. Was get an initial powersource.. It will only send it on a change.. So I had to disconnect mine from power let it switch to battery and the plug it back in..

It sends mains status only on a change.. it refuses to let me query it

Yeah I pulled it off the wall and put it back on after changing drivers and not seeing the power source show up . That was dumb luck.

But look when I convert the epoch time to human time for lastClockSet, it shows up as sometime in December of 2019 .....

That don't seem right if the clock is being synced with Hubitat time periodically. I'll check again in the morning.

Those are not my state variables .. Guess the driver you had before did sync clock

I need to start clearing out old driver states in my initial setup

Been rock solid.. I put it in place and in use immediately after posting the release.. My biggest thing is having the operating states accurate and on time, as my zone temperature control relies on it.. I have a thermostat in every room now, got rid of my unreliable and quirky centralites.. I am all z-wave with Honeywell and GoControl both my drivers

Thanks for this! It looks like a very comprehensive driver.

Except :grimacing: , I didn’t see a switch for the advanced temp reporting in the screenshots. If it’s not there, then that would make a good feature request.

And if I may be a bit direct (I’m new here, and I certainly don’t want to appear ungrateful to you or all the other devs who do great works,) I’m a little apprehensive to install this right away. Most of those settings are buried for a reason. They’re either set-it-and-forget-it or meant to be accessed so infrequently that the machinations to get to them are an acceptable speed bump to keep the average person out. Now, very few -if any-, would cause actual system damage, but they could cause the system to not function correctly or as efficiently. This is totally my own foible, but I don’t like having those settings exposed. I know the correct response to that is “that’s nice. Don’t use it,” but I thought I’d add my perspective.

I didn’t see (in the cert) a way to do that through z-wave commands.. But if I find a way.. I’ll add it.. For now that is the only thing you need to set on the screen

The driver supports the advanced temp reports .. Just can’t turn it on yet

When you hit configure on my driver, it will read in the settings from the device and set the driver preference values to what is stored in the device..

So you won’t accidentally wipe out what it is currently doing.. Also the driver defaults for these settings is the device documented defaults.. I took great care to make it safe but still give the user full control
