First thing to check is if you’ve stripped the right length of insulation. If it’s not making contact, that could explain the issue.
Make sure you’ve stripped about 11mm as marked on the wago block (here’s the official video). Also, using a test meter to check which wires are live could really help you pinpoint any bad connections.
It’s also possible the wires aren’t doing what you expect. In some setups, the live goes directly to a terminal block behind the light fitting. Your setup looks fine with the color codes, but if your home has an unusual setup, it might cause issues.
Just a thought – do the ‘switched lives’ (connected to O) go directly to the lights, or is there something else in between? Also, does this Shelly model support dimmers?
If you connect just live and neutral, does anything power up? That would help to rule out a bad relay.

Yeah, the switched lives go to the ceiling lights, though I think there might be something else in-between because there are 3 bulbs but only 2 wires
I actually tried this setup on another light in the house with the same result, and I also confirmed it’s not the relay since it powers up fine when connected to a nearby wall socket.
Some dimmers and specific light fixtures don’t play well with this setup. I’d suggest taking a step-by-step approach. First, try hooking up the Shelly to a single fixture or even a simple lamp instead of the lights to test it as a standalone unit. If it works, the problem may be with the light setup.
If you still have issues, maybe consider getting an electrician in for an hour just to see if there’s anything unusual about your wiring. I know DIY is the goal here, but once they’ve explained the setup, you could be set for future projects.
