Tuya string light (Christmas lights) Scene/Settings options

Im a bit late to this party - but I started looking for the same thing and found this

LSC Smart Connect - Christmas Lights /localtuya - Configuration - Home Assistant Community (home-assistant.io)

It is a bit involved to get the correct commands, but once you have figured it out the template makes it heaps easier. The Tuya devices do need to be set in local tuya though
