Yeelight FlexSwitch function and Tasmota

[MyHoTr]

Friends, there are several Yeelight Ceiling Light (ESP-WROOM-32D) with support for the Yeelight FlexSwitch function. I successfully flashed to Tasmota. everything works with HASSIO. However, I cannot configure the slisaON function. Do you have any ideas how to do this?

What do you expect to get with that "FlexSwitch"?

The point is that flashing the ceiling light with Tasmota totally replaces existing firmware and features. However, you may be able to do something similar with Tasmota.

it is necessary to switch the device during a short interruption of electricity (with a special switch or relay, as in my case). thus, it always remained with the supply of electricity. even when the LEDs are not lit.

Something similar was done on Sonoff Basic R4. #20247 #20067

Thanks for the idea

Obviously one of the gpio needs to be monitored and if there is a momentary change from 220 volts to 0 volts the software switch is triggered. I can't find gpio that changes this state in real time.
