Correct setup for light with switch and lamps

Hello,
I have a room where there are three lamps installed.
Those lamps are RGB wifi enabled and since they use Tuya standard I added them to HA using Tuya integration.
In that room there is a phisical VIMAR button that is integrated in HA too that cut off the power to all three lamps.

I would like to have a single HA control for evverything so I created a group with inside:

  • the switch modified with an helper in light
  • the three lights

Using this group light with a frontend light button is causing some unwanted behaviours (icon light does not correspond to real light state or sometime it switch off the phisical switch and sometime the wifi switch).

Which is the best practice to manage this kind of situation?

Thank you
Chris
