Shelly 1 Gen4 vs Shelly 1 Mini Gen3 comparison

Updated August 2026

Data from Amazon and official Shelly site.

2026 verdict

The Shelly 1 Gen4 wins this smart relay comparison on connectivity and reach, adding Zigbee (with a Zigbee router role) and Apple HomeKit to the mix and drawing on a broader integration set than the Wi-Fi-only Shelly 1 Mini Gen3. The older Mini Gen3 answers with two things budget buyers care about: it is the more affordable module and it carries the higher owner rating, and its smaller 8A body still handles the same dry-contact and wet-contact projects. Both need a neutral wire, run locally without a hub, support Matter and Home Assistant, and skip energy monitoring. The Gen4 is rated 16A against the Mini's 8A, giving it more load headroom too. Choose the Shelly 1 Gen4 if you want Zigbee, HomeKit and higher amperage; choose the Shelly 1 Mini Gen3 for the cheapest, highest-rated Wi-Fi relay in a tiny package.
