The digital inputs are a nice touch for wiring up existing switches without extra hardware, and the board itself feels like a proper reference platform for testing the Shelly X SM modules before committing to a real deployment. I've got it hooked up on my bench with a couple of loads cycling, and th

The four 16A relays are genuinely solid, and wiring up the digital inputs for a quick test took me under ten minutes. It’s a clean reference design that made evaluating the module family feel straightforward, even for someone who mostly tinkers on weekends.

I was honestly expecting more setup friction, but the 4 digital inputs mapped cleanly within minutes of wiring. Having four 16A relays on one board plus the reference design documentation made prototyping my home automation rig a breeze so far.
