Matter - Cozytouch: Issue with information feedback in Gladys

prohand · June 16, 2026, 9:41pm

Good evening,

I just integrated my water heater via the matterbridge-plugin-cozytouch plugin:

Thanks @mutmut for the link

All information is correctly displayed in matterbridge:

The information is correctly updated according to the logs:

I then added the different elements via the matter plugin of Gladys:

And I added them to the dashboard:

As you can see, the water temperature does not seem to be displayedHowever, no issues with the switches after the first activation/deactivation via Gladys, the sync with the app works very well.

Do you have any idea about the water temperature that comes up in matterbridge but not on Gladys? Or even a debugging tip?

Note that the water temperature doesn’t even appear on the cozytouch app

PS: I intentionally disabled the setpoint temperature as it is not adjustable on my device

pierre-gilles · June 17, 2026, 5:44am

Hi @prohand!

Great, it seems like this plugin is working really well

Can you download the Matter JSON nodes file that is in the Matter integration settings on Gladys’ side?

This will already allow us to see which Matter clusters are exposed, and therefore to see if any are missing in Gladys!

prohand · June 17, 2026, 6:07am

Hi,

Yes, I’ll send it to you privately

Thanks

spenceur · June 17, 2026, 10:32am

Hello the plugin was made on my side for my hot water balloon and I indeed had a problem with the feedback. I didn’t have time to dive back into it

pierre-gilles · June 17, 2026, 6:50pm

Thanks for the data, I’ll let you know when I’ve had a chance to look at it

prohand · June 17, 2026, 7:05pm

Thank you so much

pierre-gilles · June 18, 2026, 6:02pm

Thanks for the additional information @prohand, it helped me better understand the issue.

I think Gladys is currently missing a feature, as well as a few code adjustments for this use case to work correctly.

So I prepared a PR:

github.com/GladysAssistant/Gladys

Matter: add local temperature (#2564)

### Pull Request check-list To ensure your Pull Request can be accepted as fa…st as possible, make sure to review and check all of these items: - [x] If your changes affect the code, did you write the tests? - [x] Are tests passing? (`npm test` on both front/server) - [x] Is the linter passing? (`npm run eslint` on both front/server) - [x] Did you run prettier? (`npm run prettier` on both front/server) - [x] If you are adding a new feature/service, did you run the integration comparator? (`npm run compare-translations` on front) - [ ] Did you test this pull request in real life? With real devices? If this development is a big feature or a new service, we recommend that you provide a Docker image to the community ([forum](https://community.gladysassistant.com/)) for testing before merging. ### Description of change Matter: add local temperature ## Summary by CodeRabbit * **New Features** * Thermostats now include a read-only “Local temperature” sensor feature to show ambient temperature (Celsius). * **Improvements** * Temperature measurement and thermostat temperature updates now centralize initial reads and subsequent state emissions for more consistent reporting. * If an initial temperature read fails, no temperature state is emitted. * **Tests** * Expanded coverage for local temperature behavior and initial-read scenarios.

I’m also generating a test Docker image:

gladysassistant/gladys:matter-add-local-temperature

It should be available in about twenty minutes: Build Gladys dev images · GladysAssistant/Gladys@01175a3 · GitHub

Once the image is ready, could you test it and let me know if everything works correctly on your end?

Thanks for your help!

prohand · June 18, 2026, 10:10pm

Thanks

I just tested it on my test environment and I have another temperature that appeared but apparently it’s still the same issue:

I’m sending you the json file in PM

Thanks

pierre-gilles · June 19, 2026, 12:14pm

Thanks for your feedback!

I think it’s just a timing issue when starting Gladys.

I made a fix, and most importantly, I added a lot of logs to help us debug.

You can test on the same image:

gladysassistant/gladys:matter-add-local-temperature

Once you’ve tested, if you still have issues, I’d appreciate it if you could upload the log file (from Settings → System).

prohand · June 19, 2026, 12:41pm

It’s ok now, thank you
But I don’t know why I have the info twice

pierre-gilles · June 19, 2026, 3:02pm

Content that it works!

The temperature is doubled because the Cozytouch Matterbridge plugin exposes the same value via two clusters (TemperatureMeasurement (cluster 1026) and Thermostat.localTemperature (cluster 513)).

Gladys displays both if you’ve added them to the dashboard.

Why do both exist in Matter?

Matter separates functional role and device type:

Thermostat: Device that regulates (water heater, radiator, air conditioning…)|
TemperatureMeasurement: Passive sensor (room probe, water probe…)|

So the solution, if it’s not useful, would be to modify the Cozytouch plugin to expose only one of the two clusters

But in any case, on the Gladys side, it’s important to manage both types of clusters!

Does everything else work in the plugin?

prohand · June 19, 2026, 3:38pm

Ok I understand better, thanks
We won’t modify the Cozytouch plugin and I’ll ignore one of the two values

Yes everything works fine

pierre-gilles · June 22, 2026, 6:23pm

All these improvements are available in Gladys Assistant 4.80:

prohand · June 22, 2026, 7:27pm

I just tested on version 4.80 and the issue is not resolved.
I rolled back to the version with your image but I still have the problem, I don’t understand
Everything was working very well with your image the other day…

I just sent you the logs in PM with version 4.80

Any idea @pierre-gilles about the problem?

Thanks

mutmut · June 22, 2026, 8:18pm

I have the same issue with the two temperatures using a heat pump and the new Melcloud Home & Classic plugin.

pierre-gilles · June 23, 2026, 5:13pm

@prohand Are we 100% sure that the Cozytouch plugin works correctly? Does everything work perfectly with another Matter client?

Is there no issue with your Matterbridge instance?

I use it to control my Somfy/Velux shutters via a connexoon box and it works very well (with the status feedback that is not yet present in the Somfy plugin by Luligu).

pierre-gilles · June 23, 2026, 6:13pm

So I don’t get it, does it work or not?

mutmut · June 23, 2026, 6:22pm

It works for me with Somfy!

EDIT: Somfy uses Overkiz, Cozytouch uses Overkiz.

pierre-gilles · June 23, 2026, 6:31pm

Ok, I didn’t understand your message then I thought you were saying you were experiencing the same bugs as @prohand
