Hi all
I have added a new hue device to the system but it hasn’t appeared in the Aqara app.
Is there a way to add without deleting the hue hub and relinking as don’t want to have to reset all my scenes and automations?
I don’t know if you have the Aqara Hub M3 but I had that problem too.
I solved it by restarting the Hub M3.
It was months ago and I removed the Hue from Aqara since, it is only connected to Homekit now.
So I don’t know if it still happens but if you have the Hub M3, a try won’t hurt.
I’m using the m200 hub, have tried a reboot no success 
I have seen this kind of feedback on the forum before and I believe the answer was that once the Hue bridge is connected Aqara does not poll it again for new devices. So the only way to commission new devices is to remove and pair again. I’d say this is a problem Aqara should fix, but it may not be a priority for them.
