Shelly has built a reputation on making smart home retrofits genuinely accessible. The 1 Mini Gen4 continues that mission by packing Wi-Fi, Zigbee, and Matter support into a relay the size of a matchbook. This triple-protocol flexibility is the main event. It means you can connect directly to your Wi-Fi network for standalone use, integrate with a Zigbee ecosystem like Philips Hue, or adopt it as a future-proofed Matter device, all without needing a dedicated hub.

In practice, this little relay is about control. Its 8A rating reliably handles a floor lamp, a bathroom fan, or a small appliance like a coffee maker. The upgraded processor and memory make automations snappy and reliable. You’ll install it behind an existing light switch to make it smart, or wire it inline with an outlet to control a specific plug. The compact, heat-resistant design is crucial here—it fits into cramped electrical boxes where bulkier switches simply won’t.

Just note the 8-amp limit. That’s fine for most lighting and electronics, but it rules out heavy-duty loads like space heaters or large motors. For the vast majority of retrofit projects, however, its combination of tiny size, multi-standard support, and straightforward setup makes it an exceptionally versatile tool.
