I have purchased 4 IKEA LED1837R5 light bulbs and integrated them with HA using Zigbee2MQTT with automatic discovery.
I can turn the bulbs on and off using HA just fine. But if I use the wall switch, the status is not updated in HA. It maintains the last known ‘HA status’ - almost as if it is not polling the device.
Francis - thank you. This pointed me in the right direction. I turned on ‘Reporting’ and set the ‘Availability Timeout’ status check to 30 (seconds) in the Zigbee2MQTT Advanced settings.
