Hi I have a two Osram smart plus bulbs in my corridor which are inside one HA’s group. Once a while (1-2 day) not both are lightning up (randomly sometimes bulb 1 ans sometimes bulb 2 not lightnining. Then the entity is grayed and I have a message This device is considered as OFFLINE by Zigbee2Mqtt. Im using cc2531 for zigbee connection. Both of them have link quality about 70-110.
Detalis model of these bulbs: Classic A60 W clear - LIGHTIFY
What can be a problem with them that once a while lost connections?
