Dimmer 2 turns off lights right after turning them on

Configuration
1

Hi I have recently purchased 4 shelly 2 dimmers. I set one up to turn on 3 led down lights. the switch is 2 wire. so I followed the instructions for the wiring. I have done a firmware upgrade. also the led down lights are smart lights from aldi, so extremely cheap.

when turning on the lights they turn them selves off immediately.

I have done a search on here, most threads talk about flashing leds not switching off entirely. I am able to change the wiring to a 3 wire arrangement if this will help.

cheers

Check the logbook in HA: It might tell you who or what is turning it off.

I have Shelly products, but no dimmers.
