[Solved] Shelly Wiring Help (Plus2 PM with Momentary Switch)

I need some quick help. Where am I going wrong with this wiring for a Shelly 2 Plus PM? I am mocking up a light setup, and I cannot get this to work. Remove the Shelly from the path and the light switch operates. The device is also powering up and registering into the WiFi, so I haven’t managed to blow it yet!

This is the current wiring setup

This is the front side of the light switch, highlighting this is a momentary switch.

This is probably easier to show you how I have it wired. The wires coming in from the bottom of the image are from the mains. On the wall switch, I am actually using L2, not L1. It doesn’t appear to make a difference. I’ll change it to L1 shortly to make sure. [Edit - switching to L1 doesn’t make a difference]

Sorted. The ‘Live’ on the wall switch needs a permanent live. Also, the ‘Neutral’ I had wrongly interpreted as a neutral (marked as 01 on the Shelly) is actually the switched live. So it goes into the live input of the bulb. Then the output of that bulb, the neutral - connects into the mains neutral. All sorted and working as hoped.
