Sylvania Light Strip Won't Connect

What happened

Whenever I try to connect my Sylvania 73773 strips to my Zigbee2MQTT(Home Assistant addon), it says “Received message from unsupported device with Zigbee model ‘Flex RGBW Pro’”. However, last week they worked(different HA install) and I checked and they’re definitely on the supported device list.

What did you expect to happen

I want them to connect to my Home Assistant! :slight_smile:

How to reproduce it (minimal and precise)

They just simply won’t connect. I have tried uninstalling and reinstalling practically everything.
