    Hi,
    I'm in the process of planning an electrical installation at home and have encountered a conundrum as to how to connect a smart home device from Tuya to an installation with lighting.
    The diagram would look as follows: 2 light circuits, 3 double switches (2 staircase, one cross) and I don't know how to connect this to the module from Tuya. The cables haven't been laid yet, so maybe someone can help how to do it right. Below are 2 diagrams that I would like to connect together.

    You connect according to the diagram as for a cross connection.

    Is anyone able to diagram this for me yet along with connecting to the network? I'm trying this way but something must be going wrong. The tuya works, but the switches don't.

    You have drawn.
    L1 and L2 are the power line (Phase)-the wire colour 230V brown or black
    N-neutral - cable colour blue
    PE-ground - wire colour green/yellow

    You connect the N wire directly to the lighting point (bulb), and to the power supply of the SMART module
    L wire is connected through the switches and the SMART module as shown in the diagram.

    Connect these switches on the table for a test, it appears that you are connecting the switches incorrectly.

    After further tests it appears that the problem is with the cross-over, most likely I have a faulty switch, on the two stair switches alone everything works.

    Don't blame the equipment just check the connection five times. An arrangement of two staircases and one cross-over in the middle and yet all of this times two and in shared boxes is heavily complicated, it's easy to get lost; many times I've rescued less patient contractors once they've given up.... And sometimes they would abandon the customer saying that something was in the cables and "it's not possible"
    Greetings. J.

    A solution was found! Final cross switch working, as a colleague wrote, but I didn't mess up the wiring, and the diagram from the manufacturer for connecting the switches was wrong. To make it work, it's a diagram as above, but with the difference of plugging in the cross switch. Looking at the diagram above, the wires going from the left hand staircase should be plugged into the top wires on the cross-over (not 2 top and 2 bottom from the left as in the diagram), and down plug the wires going to the right hand staircase, plugging in the wires, keeping the analogy of plugging in from the top wire on the left hand staircase.
    And then everything works: both staircase, cross and Tuya :) .

Topic summary

The discussion addresses the integration of a Tuya smart home module into a lighting installation featuring two light circuits controlled by three double switches arranged as two staircase switches and one cross switch. The installation wiring should follow a cross-connection scheme, with the neutral (N) wire connected directly to the light fixtures and the smart module's power supply, while the phase (L) wire is routed through the switches and the Tuya module. Initial issues with switch operation were traced to incorrect wiring of the cross switch rather than faulty equipment. The correct connection involves swapping the wiring on the cross switch so that wires from the left staircase switch connect to the top terminals of the cross switch, and wires to the right staircase switch connect accordingly, differing from the manufacturer's original diagram. This corrected wiring ensures proper function of both staircase and cross switches alongside the Tuya smart module.
