    Good day,
    I am considering the question of selecting smart lamps for bus-wiring. I would like to add all the lamps to the Tuya application using a ZigBee gateway. After all the configuration, suppose I switch off the lamps in the evening using the app and then in the morning I want to switch them on classically using a switch mounted in the electrical box. So I change the state of the switch from short to open and then back to short again. Is it possible to configure the lamps in this application in such a way that they return to the operating (lighting) state after a power failure?
    Thank you very much for your help, as I have doubts about whether I should opt for such a solution.

    This is not possible, and it is pointless. When the power goes out, the lights would turn on and consume electricity. Imagine this happening when you've just been away for a few days...
    You change all the lamp switches to Wifi switches and configure them as you wish, so that the electronics and software are responsible for switching the lamps on and off, rather than physically cutting the power.

    Thank you for your help,
    that is, the only solution is wi-fi switches, but in this case would I not lose the option of controlling the lighting color?
    Because I can not find in the offer of any manufacturer that the switches have such an option.
    So I have to decide on one solution or the other?

    Honestly, you would have to buy one such switch and check more carefully what the exact configuration options are with these lights. Normally in these systems everything is done either by an app or a Zigbee gateway, and you only set the dependencies between the devices with your smartphone. I have it set up myself, for example, so that when I open a window the radiator automatically turns on (thermostatic head on wifi), and the switch from the light 3-field middle channel turns on the fan. I don't know if in your case you will only have the option to set that switch to be able to turn on the lamp and it will light with the default, previous parameters, or if you will be able to specify exactly which switch will light which lamp with which colour. This is purely a software issue and I can't say anything 100%.

    Ok I will order wi-fi gateways and switches and just try to test the possibilities of the application
