Hi, I am starting to see many of my matter devices is offline/unavailable. Its both on the Nanoleaf and Ikea apps that it seems to go “offline” Do anyone have some idea where I should look to maybe see if its a HP23 issue with Matter devices since IKEA is the new addon to this.

Please stay on topic “Matter devices are unavailable” and take off-topic discussions in appropriate topics/categories.

Is discussing the possible reasons why Matter devices become unavailable really off-topic? In my view, the topic is not only that Matter devices are unavailable, but also what could cause this behaviour.

[image] deejayreissue: My ticket was closed without any resolution to the memory leak issue In this case I’m referring to the issue you were facing with Matter, the one talked about in the other thread I referred to. This thread is about Matter devices being unavailable. I’m not sure which m…

[image] Sudden CPU frequency drop from 1.3GHz to 0.9GHz since v13.3.0 Adding a device setting that allows users to adjust how frequently devices send updates, making it easier to reduce unnecessary network traffic when needed. 15 Thread messages per second sounds like a lot at first glance. A…

[image] Pascal_Nohl: A good mini-PC running Home Assistant with a dedicated Thread radio would probably not care much from a CPU point of view I think it isn’t related to CPU at all. At least with Zigbee, the amount of messages it can handle are limited by the radio, not by the CPU. Even a ch…

I removed both the Eve plugs and the IKEA plugs and the issues remained.
