The clock on the thermostat is just for display purposes and is purely cosmetic in nature. The DTH sends a clock synchronize command once every 24 hours to sync the display with the time on the hub . You can force it by clicking the refresh tile.
It’s completely unrelated to the SmartApps which run off the hub time.
However the common thing I see between them is that it looks like the commands aren’t reaching your thermostat or are being dropped in the mesh. There a lot of reasons for this but some common ones are: It’s best to run the thermostat on a C-Wire (requires re pairing) and have a repeater within 30ft or so. Rebooting the hub and doing a zwave repair once a month also helps fix mesh issues.
OK - thanks. i will keep an eye on it now that I have updated to the latest version of the DH. It looks like the time is displaying correctly since that change.
For the C-wire, I don’t have a good option to get power to it, unfortunately.
I have a repeater (Iris Smart Plug) in the hallway near the thermostat, but I am not sure if it is functioning correctly.
If the issues continue after the update I just did, I will try the reboot and zwave repair.
You may want to check our a Venstar system which can add an extra C wire to exiting setup without a running a new wire.
FYR, the IRIS Smart Plug doesn’t act like a reliable z-wave repeater even though it’s capable, rather it is also know to cause issues with the zwave mesh as reported by other folks on the forum.
Thanks for that info - I will dig into both of those items (especially the Iris repeater comment).
There is already a device installed that adds a wire (or two?) - since we had a heat-only system and added AC later (after we bought our house). They installed something that provides the wire needed for cooling, but it didn’t add the C-wire. I took photos of this back when I installed the new thermostat, but I have to dig up the photo to get the details.
Is this still not functioning yet for the NEW SmartThings app? Excluded and Re-paired the CT101 to the hub with the Device Handler already added and I cant even see the Humidity or battery level. What am I doing wrong?
Thanks for the update! The Remotec “Filt” reset is working perfectly. Nice job. Being able to configure the hours for filter change is a great feature.

It will only show C-Wire if the thermostat was paired with the hub in repeater mode (i.e. with the C-Wire connected) otherwise it shows the battery level.
Just want to thank @Rboy for putting this latest update together. He added the Filter Replacement Timer functionality upon my recent request when I discovered my ZTS-500 was flashing “filt” and there was no way to reset it without doing a factory reset on the thermostat. (No thanks!)
If anyone ever wonders if rboyapps.com Device Handlers are worth the price of admission, the answer IMHO is YES. I signed up about two years ago to get my Schlage Locks “fully” supported, and I’ve ended up using most of their other DTHs over time. And because @Rboy has been responsive with enhancements and updates, I’ll never have to perform that factory reset! Thanks @Rboy!
Is there a bug for CT101 for screen lock? The app shows partial lock but on real thermostat it’s full lock. So the handler actually missing the partial lock. And if lock is changed from screen, app won’t update status.

Some thermostat models don’t report the status (firmware bug) of the lock state hence it should ideally be changed through the ST app and “slowly” since it needs time to execute. It helps to have the thermostat run on a C-Wire with a repeater close by to buffer the commands to avoid sync/lost command issues.
I do have it with c wire. When I change from the app partial-full-unlock cycle, the thermostat actually is full-full-unlock cycle no matter I change it fast or slow. When the icon blink which means it does receive command but just executes the wrong one I guess.
Since the most recent update, my Lowes Iris CT-101 is reporting just fine, but I cannot control it. Fan, lock, temp, etc… it does not respond to any changes I make through the app… but the app shows any changes I make on the thermostat itself. Is it possible to access older versions of your handlers so that I can test which update it was that broke it? Now that I think of it, I may have missed the last 2 or 3 updates before getting this one 04.04.02.
Also, the CT-101 does have a “replace filter” light and it would report usage hours in Iris. I still see it flashing on occasion, and when I physically interact with the thermostat, it goes out. It appears to be resetting an internal timer or something.
FYI: I noticed all of your references to the CT-101 is based on the device reporting MSR: 0098-6501-000C, but mine is reporting as MSR: 0098-6501-000B

Your thermostat has lost directional communication with the hub (only one way channel works). Hit the black reset button on your thermostat and then tap the refresh tile to resync it. If that doesn’t work you’ll need to exclude and re pair your thermostat. This often happens due to power fluctuations on the C-Wire and/or a bad battery.
I can try that. FYI when I switch to the regular smart things Z-Wave Thermostat handler, I’m able to control it just fine. When I switch back, it’s broke again.

Try the exclude and pair the thermostat again and double check that there aren’t any copy paste errors while updating (starting over is the best way to eliminate such errors). Haven’t heard of any issues and it’s working fine here with all the models in our labs so it’s likely something local. Also see my PM about the raw description details.
After moving my hub right next to my thermostat and excluding and pairing AGAIN, things are now working. Thanks to some more help from @RBoy, we figured out that my Z-Wave Raw Description in SmartThings was showing up weird. I was getting:
At this point, I’m assuming that the previous Raw Description was due to low signal, but apparently still strong enough to pair? After getting that straightened out, I was able to put my hub back and control my thermostat using this DTH again.

Is there any way to tell for CT101 if the thermostat in repeater mode or not?
I am waiting for crazy weather to be done within the northeast before I can install Enhanced Z-Wave 4.05 app, currently still on the free app. I have C wire attached through external transformer (to C and Rc) and I only see a percentage for battery one thermo showing %100 and the other shows %92. I have confirmed that incoming 24V is there (if I pop the batteries out I still get picture!). Would I see c-Wire remark for battery in free app or is it unique to Enhanced app?
I have just installed the device for Enhanced z-wave plus thermostat. Currently I am using the 5-2 free edition thermostat with 3 thermostats. How do I do the switch over to the enhanced? Do I simply edit each thermostat and change the device type from CT100 to Enhanced z-wave thermostat? Do I delete the existing heating schedules for each thermostat and recreate them?
I think you’re asking a question related to the 5-2 Day Thermostat SmartApp in the link below (which should also answer your question that asked by another user)
This topic is related the z-wave thermostat device handler.
