Thread devices unresponsive since yesterday, driver update problem?

The error is triggered by Matter 1.3 devices with energy monitor, like the P110M which was recently updated. Since Matter lights use the same driver and the driver basically dies, so do the lights.

You can wait a few hours for the official fix or switch the driver of the plugs to use mine (assuming those are your only devices with power monitoring in Matter). As an added bonus you’ll be able to get the power and energy readings, current, voltage and make the indicator blink for visual notifications.
