LightwaveRF replacing Double Pole Switch

[willbeeching]

Hi guys, new member to forum here.

I recently bought a new build and I'm slowly replacing the light switches with smart LightwaveRF ones. Most of them I've been able to work out myself and some googling. However there's a 2 gang switch on each of my bathrooms where one of the switches is a double pole switch.

I'm unsure how I can then connect this to a LightwaveRF switch properly. My bathrooms don't have extractor fans, but they are connected to a ventilator system in the roof which I believe when the light switch is turned on it boosts for ~15 minutes.

Any help would be awesome, photo attached.

Thats a very busy backbox.

I dont think Lightwave do a DP switch as such... but there might be a way of using one switch to control a hidden relay, thus 2 switches with one operation.

Ive never like DP switches on lighting. The terminals are marked N for neutral, but its a live cable there. Could be confusing for DIY
