Local tuya RGB bulb added, showing state but can't control through HA

Have just got 2 more RGB bulbs, I can use smart life app to control it.
Added through local tuya, it’s only showing the states but not able to control it at all…
turned out I have log returned it’s not able to connect…
Don’t really understand what is happening… can anyone help?
