Heltun z-wave heating-thermostat

Any have this or know if they are working with homey. I have 2 of this using on Fibaro hc2. I want to start using with homey.

any?

If there is an app (for Homey) in the appstore and your devices in the supported list, then it will work.
If not, then you’ll have to write an app for it yourself, or request the community to write one for you, if you can’t.
Without an app, device’s can’t do much in Homey.
