Light is not reachable by hue bridge: what does this mean?

Hello,

My Hue lights are working fine.

But I see the error, light is not reachable by hue bridge. What does this mean?

I have rebooted the hue bridge and the smartthings bridge and still this error in the logs.

Thanks in advance

What it means is that Hue sent a command and did not get a timely response.

Unfortunately, SmartThings will stop sending commands to bulbs in that state even though they may still work just fine.

You will find much discussion, including from SmartThings staff, in the following thread:

New Hue delay

This is just an indication from the hue bridge that it did not receive a status update from the bulb in a timely manner. For some reason smartthings is interpreting this as the bulb not being available and does not send an instruction any more. This happened during the August firmware update. If you try the hue app or any other hue compatible app you will very likely notice they continue to work. This is not related the OP regarding delays.

Definitely put in a support request.
