I'm struggling with the connection and, unfortunately, I'm once again proving to be a nightmare switcher. I am trying to replace the Legrand two-key switch (up-down, 0-1) with the Tuya switch mentioned in the title. The aim, of course, is to be able to control it remotely.
The flat's wiring is legitimate, 3 wires:
* brown 1
* blue
* yellow-green
There are 4 wires going to the motor:
* brown 2
* black
* grey
* yellow-green
Legrand is connected as follows:
L: brown 1 (power supply)
Top (1): black
Bottom (2): brown 2
In addition, the yellow-green from the house installation is connected to the grey of the motor.
I connected the controller as follows:
L: brown 1 (power supply)
OPEN: black
CLOSE: brown 2
N: blue
I left the yellow-green from the house installation connected to the grey of the motor. The controller did not even light up.
The other wires remain unconnected. Everything works. Can anyone n00b give a hint as to what to screw where on the Tuya switch?
