I cannot see any discernible difference between different power on levels, nor start up colour.
No options to select a colour.
Searched for previous posts on this model on here and can see some people did have the colour wheel available.
I did delete it from ZHA and re-add, no different.
Any suggestions?
Edit: Forgot to to say, I have the SONOFF Zigbee 3.0 USB Dongle Plus V2 dongle. Other Zigbee devices work ok.
They are likely based on Tuya firmware. If they will also work with the SmartLife Phone app, You may have other options with one of the many Tuya based Custom Integrations or something.
You misunderstand - you suggested trying the Smartlife App, I was saying that I can't do that as I do not have a SmartLife/Tuya Zigbee gateway that would be required.
I only have a Sonoff gateway which is plugged into the HA server.
