Electric blinds wiring

[rumavil]

Dear all,

Thank you in advance for your support on my question.
I have an electric blind in my daughter´s room, controled via a wall switch ( Btcino ).
I ordered a Wi-FI switch and when trying to install it I get this:
Current switch is "feed" by three cables coming from the wall ( no more available ) One was feeding L, and two others feeding 1 and 2, so I´m guessing up and down.
New switch however, as 4 entries ( L, 1, 2 and N). I can´t seem to figure out how to put it to work.
L is a no.brainer ( i guess ). If i and 2 go to 1 and 2, the switch doesn´t even light up. If e.g. 1 goes to 1 and 2 goes to N, switch turns on, but no work.
Please advise'
Thank you very much

Cheers
Rui

Sounds like you need another cable for the N neutral connection. L will be live and 1 & 2 will be up and down but the switch needs a neutral to operate.

Thank you for this. I imagine that is the thing, but I have nothing else coming out of the wall, only those 3 wirtes. Wondering if the Btcino switch uses one of the 2 for N?
Thanks
