After months of limited success with matter, I successfully added this bulb to Matter. These are inexpensive on Amazon

Did you first add it to another platform, then use a share pin or QR code to add it to your eisy?

I added it directly through UD mobile "add matter device with QR code". I don't have another platform to add with.

Initially, I wasn't trying to add the bulb to the EISY. My non-device porch light burned out and I was out of regular bulbs. I remembered I had the Linkind bulb so I installed it until I could get to town for new regular bulbs.

In the past I was unable to add the Linkind bulb and had given up on them. However, when I powered on the bulb it started flashing to indicate pairing mode. On a whim I tried to pair it using UD Mobile. I was very surprised when it paired and the color slider toggle icon appeared in the Home section.

Wow, nice! First time I hear of a direct add. You're running IoX 6.0.5?

I could not remember for certain, but I was thinking that matter-over-wifi could be directly added. It was only the matter-over-thread that I thought required another platform. Having said that, I don't even remember whether I have tried.
