Stelpro releases the first Z-Wave Plus Line-Voltage thermostat: the STZW402+ Stelpro Ki Thermostat

Hey J-F,

it would appear that on their last update, Smartthings changed something that affected your z-wave handler again.
It’s no big deal this time as everything still works perfectly, but the green circle in the bottom, middle tile only says “setpoint” in really small letters.
You can still see your setpoint in between the arrows though.

Hi Paul,

Thanks for the notification.
It appears that the valueTiles don’t longer support having text on multiple lines.

So I will simply remove the setpoint circle tile since the setpoint is already shown in the main tile.

Hello, please excuse my ignorance in the following question. How do I apply this device handler? I’ve got a Samsung Smarthings hub Rev 2 and a light switch working via Echo Alexa by calling routines created in the Smarthings app.

I cannot get Alexa to change the temp routine which it looks like this device handler handles, but I don’t know how to apply it.

Thanks so much for any info you can supply!



Normally you had to go through the smarthings IDE

then go to Device Handlers
create new device
From code

then paste the content of the txt file

then go to my device, lookup the stelpro device and edit it, if you look at type (scroll down the list) you should see ur newly added DTH

Now i do not have one, i just stumble across your post

Thanks Eddy - I’ll give this a go!

Thanks Eddy for the info. I got the new Device Handler installed and it works way better than the original, BUT still doesn’t solve the problem. Bummer.

Glad to help, hope you’ll get it working eventually

i installed this smartapp (thanks for developing for the platform!) but im not sure i understand what it does exactly.

here’s my guess after trying it… IF you have a remove temp sensor on one of your stelpro’s, you can display that reading on other stelpros so you don’t have to have a remote sensor on them all. is that it?

i connected thermo 1 to thermo 2. thermo 2 had a setpoint of 52 and ambient reading of 60, but the ext on termo 1 said 57. not sure where the 57 was coming from…

Hi @skyrun,

The SmartApp purpose is to make the outdoor temperature (or any remote sensor) displayed on the thermostat.
It does NOT replace the internal sensor

For the Alexa implementation, please check out these posts:

Is it possible to set the thermostats temperature with google home? I just installed two of these and it replies that the device doesnt have that feature, using the device handler linked in this thread.

The current device handler was not design specifically to work with Goggle Home.

I’ve both Z-Wave and ZigBee versions, both exhibit the same behavior with Amazon Alexa.

If I say, “Alexa set the [Thermostat Name] to 68 degrees.”

Alexa responds, “[Thermostat Name] is in a mode that doesn’t accept requests. Please change it’s mode in the SmartThings app or on the device.”

I’m using the updated device handlers ZigBee (Date: 2017-07-21) and Z-Wave (Date: 2017-08-21) from HitHub.

Anybody having more success?



Any estimate if that will ever happen?
Because it seems weird that at this point I have to choose between @JCon 's solution and lose the exterior temperature or keep the “Official” handler and lose Google Home control…

We are working on it.
I have reached @JCon in order to understand how he managed to make our device handler Google Home compatible.
He agreed to collaborate with us, so you may expect something soon.

I am ready to grab a couple of these for the condo. I am curious to find out if there will be an app to allow 5-2 schedule or programming similar to apps wrote by RBoys?

I want to be able to pre-heat the home at 5am in the morning and 3pm in the afternoon that kind of automation.

Could IFTTT takes care of this?

Hi @killer23d,

Yes, IFTTT can do the trick, that’s for sure.

That would be fantastic!
