MQTT light switch that сonsistently on few lamps

Configuration
1

I have chandelier with 6 lamp.
I need configure switch(button?) that will switch on one more lamp each time -
first click - 1 lamp on
second click - 2 lamps on
…
sixth click 6 lamps on
seventh click - all off

Lamps are controlled by MQTT topic.
To switch lamp on I have to send lamps number in payload.
Or 0 to switch all lamps off.

I don’t have any idea how to do it.
Please help me.

I can’t think how to do it with a button, but would an input_slider UI do? Slide the input to the number of lights you want on.

You would then need an automation to send the correct MQTT messages for each input level.
