I am running HA 2025.4.1 and ZHA with the ConBeee II stick.
Over the last couple of weeks my zigbee sensors have been slow to trigger automations, and several of the devices have dropped off the network, forcing me to re-add them. My Zigbee network had been stable for ~1 year.
Any known changes to HA or ZHA or other ideas? I didn't see anything in the change logs.
