Twice in the last week I’ve had a matter over thread battery powered device become unresponsive, as opposed to offline. Its status was still showing as online but it wasn’t generating events . In the first instance it was a IKEA myggspray motion sensor, in the second it was a generic door sensor fr…

I’m assuming this means the cloud to cloud integration route (eg smarthings to Amazon Alexa). The disadvantage of this approach is that not all the capabilities are exposed via this route, eg only the temperature of the IKEA air quality sensor is exposed to Alexa, so you can’t for example use Alexa …

Correct, the suggested workaround is the cloud to cloud integration. And I don’t have any experience with Alexa. But as a workaround to cloud to cloud limitations, I used my BILRESA button paired in ST’s to increase or decrease the volume of my Google Home speakers using virtual switches. I also u…

It’s more expensive than the IKEA Matter/Thread door/window sensor. Leave that one off and see whether things improve.

Yeah, I took it off before Christmas, all my thread devices are now Onvis plugs, Nanoleaf lights and ikea motion,contact,temp,air quality sensors

Can you reboot your isp router remotely? If so, I would try that then wait for the mesh to rebuild.

I just “solved” it by keeping the device close to the v2 Hub. (I am on the location, but will leave tomorrow) When holding it next to the ST hub, I removed the battery en did this 4 click on the button. But no light to be seen. And on a certain moment I got my Sharptools message that it was “open”. …
