Starting with the latest Homey 7.1.5 update, I have now lost contact with 3 Heatiit Z-TRM3 thermostats. 2 of them are still ‘reachable’ - but they do not respond to commands. Be grateful for any advice on this. Have tried restarting both Homey and the thermostat.
Hesitant to reset Z-wave as I have more then 20 devices, including dimmers in ceiling and walls

There is a separate thread for HeatIt. HeatIt itself is more or less active in this thread. It would be better to post your questions/problems in this thread.
OK, not sure whether this is a Heatit or Homey issue. But I’ll try there as well.
thx
I seem to have the same issue
Hi, this is an app issue that arose after Homey updated to version 7.0.0.
An update we are releasing will probably resolve this issue.
Thank you so much for the information!
Hi.
I still have this issue with my 3 ztrm3 thermostats.
Have you released the update? What is the newest version of the app?
I had to reinclude 2 of my z-trm3 and factory reset and reinclude a third one. But now they’re all working as normal.
Hi,
There is an issue with S2 security on Homey. I suggest you reinclude the devices and when it asks for a dsk code you type 0 0 0 0 0 instead.
my Z-TRM3 also lost connectivity with Homey pro at some time… probably after the Homey update to version 8.03.
trying to pair with the in-app instruction did not work… always ending with “ERR” on the thermostat.
indeed after a factory reset (thanks for that tip) of the thermostat the pairing worked again…
i had a Schwaiger zwave hub that had similar issues in the past. (after half a year it lost connectivity and never got it working after…).
my suspicion is that the heat-it z-wave implementation is not very robust…
