Mystery with light

[dorasvk (Dora)]

Dear all,

Please, help me with this mystery. I will explain just the core, as all things are perfectly working {HA, RfBridge with tasmota} BUT

I have an outdoor led light which I want to operate through MQTT switch…

the switch is operated perfectly when it is not connected to LED… when I connect it - I can switch the light on but not off …

but with the original system {Trust Octopus} i can still switch it on and off without problem…

when I put another led - everything is working fine…

just for illustration, the connection attached…

If any ideas… please help me

I see one blue and one brown wire not connected but stripped.

Edit: perhaps there is one green-ish colored at the top also, and the ground wire.

From the picture, it is not a sonoff mini. and some wires are not attached. Without more information it remains a mystery.
