MagicHome LED Strip - MQTT Light - Brightness 100% When I Change Colour

Configuration
1

I turn on the light, set the brightness to x%, then when I change colour it changes but the brightness also changes to 100%. I want to keep it at the previous brightness level.

What have I got wrong in my configuration?

Thanks!

Having similar issues also. Just recently flashed the MagicHome controllers with Tasmota.
Bedtime script slowly dims the lights down but now it briefly flashes us at each increment

@automationpirate - solved this, found a fix deep in the Tasmota issues list. I changed the topic I am calling in my above configuration

rgb_command_topic: “cmnd/deviceName/Color" to call Color2 instead. Now respects the brightness when changing colours and turns on at the correct brightness (I was originally getting 100% for a split second before it dimmed).

I recently found using the dimmer command was working rather than sending power all the time.
Only issue is when I send “DIMMER 0”, home assistant doesn’t seem to realise it’s actually off.

Your way seems better, I’ll give it a go.
Cheers!
