#Renaming Matter (over Thread) Devices does not change Entity IDs

Hi all!
I just got my Matter over Thread devices working, namely two Ikea Alpstuga air quality monitors.
When i tried changing my dashboard mini-graph-cards to use these sensors I realized that changing the name of the device does not change the names of the entites; e.g. original name of the device: ikea_alpstuga_air_quality_monitor
new name:
office_environment_alpstuga

both before and after the rename the entity name for the temperature sensor was ikea_alpstuga_air_quality_monitor_temperature

for these two devices i manually changed all the names to match the new device name (office_environment_alpstuga_temperature) but it feels like there should be an easier way. Did i do something wrong, or is my expectation skewed (coming from zigbee2mqtt)?

#

Update: I just found the "Recreate entity IDs" function, but sadly it does not do what i expected. Excerpt from the popup:
(old name) sensor.office_environment_alpstuga_air_quality (new name) sensor.air_quality_2

so it seems this function does not take into account the device name at all

which versions of HA core and matter server are you running?

HA Core: 2026.01
Matter Server: 8.1.2

I am still on 2025.X -- there the "Recreate entity IDs" function derives the entity names from the the device name. So this might be a regression?

@eternal kindle : did you try that for a matter device or something else?
For an MQTT device (zigbee2mqtt) it does work as expected, only for my new matter devices it doesn't (as of now i only have those two, so i cannot test with further devices)

Matter. Same server version.

Interesting. I ordered a few further devices (all Ikea) and will test with those when they arrive.
