Gledopto GL-C-009P not working correctly

Hi, I have a Gledopto GL-C-009P connected to ZHA via a Tasmota flashed Sonoff bridge.
I have been able to successfully pair the controller however it doesn’t function within HA. The power is on and if I try and toggle it will revert back to “on” within a few seconds with no state change to the led strip connected. Moving the brightness wheel also has no effect.
If I go into clusters and manually send an “off” command the light will respond accordingly.
I am still quite new to all this so any assistance would be appreciated.
Thanks
