Zigbee2mqtt unsupported device TS0504B

I’ve had that same model supported and working for the past 2 years.

Worst case scenario, yours had a different Zigbee Manufacturer ID (extremely common with Tuya) and you just needed to wait 3 more weeks for that to be released into the main branch.

PS- don’t tag people who are not already part of the conversation - it’s against forum rules
