Sonoff Mini - 2 way switching - UK

Hardware

Does anyone know if it’s possible to set up the Sonoff Mini with 2 way switching and UK Wiring please?

no idea, but I know that the LighWaveRF switches that I have have special wiring for 2 way switching. I suspect the same is required for sonoff.
[EDIT] the sonoff home page appears to answer your question. Did you look at it?

I did look at that and tried wiring it up as shown but the switch didn’t work as expected - I’ll check my switch as I can only assume that it’s faulty!
