Unable to re-add Matter device

i have two Matter RGWB Smart Bulbs that have been working fine for several months. Suddenly, they became “Unavailable.” Repeated attempts to read then to Home Assistant failed. I have had some difficulty adding Matter devices.

I have tried adding the bulbs both by scanning the QR code and entering it manually. Both devices have been “factory reset.” Anybody have a suggestion?

Thanks.

My Nanoleaf bulbs require me to switch them off and on a large number (12?15?) of times at a certain speed (once a second?) then they show red and can be added to another (or often the same) Matter setup.

Thanks for the tip. Worked Ike a champ.
