[Bug]: Temperature Sensor information in Alexa not updated?

[jbaumann]

Version

3.0.0-alpha.83

Matter Controller

Alexa

Steps to reproduce

I have a binary sensor (door/window contact) and two temperature sensors exposed via the matter hub. In the overview page of the matter hub in HA they show the correct and current information.

In Alexa all these sensors show up. The door sensor in Alexa is updated at once if I change its state, which to me suggests that everything works as intended. The temperature sensors are not updated regularly in Alexa, even though they are updated correctly in the overview page of the matter hub.

There is no error shown in the log.

Is this a bug or is the temperature only updated once in a while?

State and attributes

The state of the contact sensor:
device_class: door
icon: mdi:door
friendly_name: Balkontür_WZ_contact

The state of the temperature sensor:

Ok, I created a second bridge and connected it to Apple Homekit. There all sensors show the correct values. This to me suggests that the problem with the updates is Alexa-related.

Without having measured it in detail I think that the data is updated roughly every 10 minutes.

If there is no additional comment/observation I'd suggest closing this issue.

I had the same issue : the June 2nd 2025 i've installed for the first time 3.0.0-alpha.83.
Initial setup : OK
Pairing : OK
Logs : no error
But temperature sensor was not updated into Alexa.

Today :
I have fully rebooted the raspberry, and installed version : v3.0.0-alpha.86
Now alexa is updating my temperature sensors.
I don't know if the full reboot, or the new addon release, or alexa services fixed the issue for me.
