Heatit Z-TRM3 Thermostat?

I checked on the Indigo compatibility list for the Heatit Z-TRM3 thermostat, but it is not on the list. I do not have this thermostat yet, but wondering if...

a) Any plans to fully support in a future update?

b) Does anyone have this thermostat today, and how well does it work in Indigo? Any gotchas I need to know about?

Re: Heatit Z-TRM3 Thermostat?

We'll look into adding support for it once someone has one and submits the device profile from Indigo to us. We currently support the TRM2fx, so adding support for this model shouldn't be too difficult. Basic functionality will likely work out-of-the-box with the current version of Indigo.

Great. Re-sync it and also copy/paste the Event Log results into a reply for me here. Also describe what is not working. Thanks.

Re: Heatit Z-TRM3 Thermostat?

Here is the requested sync.
The only thing that work is that I can request a status update and see the set temperature.
The device is divided in 4, 1 Thermostat and 3 Multilevel Sensors.
None of the sensors are reporting anything ( I have currently not connected any external sensors to it, just the built in one)

Notwithstanding the Indigo update, how do you find the unit? One of the reviews on Vesternet makes it sound a bit tempermental... whats your experience been?

My experience is that it is very stable, I have only clicked troughs it’s menus and installed it in the wall. I set it for 22C and it has worked really well. Can you please refer the the review and I can read it and comment on that. I read somewhere that there was a firmware upgrade to it, I have not looked in to that, I was in a hurry to install it, because the old was broken.

Re: Heatit Z-TRM3 Thermostat?

To warn everyone - the previous model has nearly burned my house.

The thermostat relay was staying in the "on" mode, ignoring safety limits, and in some areas, the floor was ~100C, basically burning hot. It used to work fine for ~3-4 years.

Some parts of the floor are damaged irreversibly.

We are fortunate that my wife noticed the issue, and we were at home.

How far away are we to get support for this device?

I hope to have it supported in the next release. No specific ETA on the release date yet.

Re: Heatit Z-TRM3 Thermostat?

Hi, I downloaded the new version but it didn't work for me.
I removed and added the device from Indigo, but it still doesn't work.
Do I have to unpair the device and pair the device as a z-wave unit to get it working?

Re: Heatit Z-TRM3 Thermostat?

We are looking into this. The module seems to be misreporting its capabilities. On one hand it reports that the endpoint 1 device is a thermostat, on the other hand it doesn't list any of the thermostat command classes as being supported by endpoint 1. So Indigo creates a thermostat device mapped to endpoint 1, but then when it tries to send commands to it realizes it doesn't support (or claims to not support) those commands and doesn't send them.
