I use the Blue 2-1 notification LEDs to indicate conditions like the garage door being open or the backyard gate being open. I set a switch in each room with the notification. This leads to a lot of messages being sent out over the Zigbee network (ZHA under Home Assistant) and results in the occasional failure . I suspect this is due to too many commands flowing at once. The message I get is:
Failed to send request: Failed to deliver message: <EmberStatus.DELIVERY_FAILED: 102>
Is there a way to send the command out as a group command instead of a cluster command? Or are there any other ways to reduce the likelihood of a message not making it?
