***Now UPDATED to work with the latest versions of HA and Local Tuya***
Tested and working on Home Assistant 2022.2.5 with Local Tuya v3.4.0
.
If anyone’s interested; here’s how I have it setup.
Main picture - Turns ON Fan and Light
Fan lower left - Toggle Fan - Spins when ON
Palette Icon - Select colour, brightness and effects - Icon changes to selected colour
Fan(1) - SET Mist Low
Fan(2) - SET Mist High
You will need to have " custom button-card " installed for this to work. Install this through HACS.
Also the image you would like displayed to be in your " www " folder and saved as " diffuser.jpg "
FAN - DPS 1
LIGHT - DPS 5
SCRIPT
Diffuser :
This toggles the Fan and Light; there are other settings you can play with here but I selected just these two.
For the Sequence you will need two Call service Action types. The first one to toggle the Fan; the second to toggle the Light.
Select Call service for the 1st Action type and " fan.toggle " in Service and pick your device.
Select Call service for the 2nd Action type and “light.toggle” in Service and pick entity.
Save this. Test to see if it’s working by pressing the Play button in Scripts Menu.

SAVE. Done. 
Hopefully it works.
