Shelly 1 Mini Gen4 vs Shelly 1 Mini Gen3 comparison

Updated August 2026

Data from Amazon and official Shelly site.

2026 verdict

The Shelly 1 Mini Gen4 is the better smart relay of this pair, adding wider platform integrations (Apple HomeKit alongside Alexa, Google Home and SmartThings) and a Zigbee router role that the Gen3 lacks. Both modules are near-identical tiny single-channel relays, rated 8A, needing a neutral wire, with dry and wet contacts, local control and a 3-year warranty, so this is a genuinely close generational step. The Shelly 1 Mini Gen3 remains the more affordable choice and is still a superb budget building block for garage doors, sprinklers and low-power loads over Wi-Fi. Pick the Gen4 if you want HomeKit and Zigbee mesh routing; keep the Gen3 if price is the deciding factor and Wi-Fi control covers your needs.

Frequently Asked Questions

Is the Shelly 1 Mini Gen4 or the Shelly 1 Mini Gen3 the better relay?

The Shelly 1 Mini Gen4 is the stronger pick overall. It broadens integration support to include Apple HomeKit and adds a Zigbee router role, extending your mesh, whereas the Gen3 tops out at Wi-Fi-based control. The Gen3 wins only on being the cheaper unit.

What is the biggest difference between the two Mini relays?

Connectivity reach. The Gen4 acts as a Zigbee router and works with Apple HomeKit on top of Alexa, Google Home, SmartThings and Home Assistant. The Gen3 is Wi-Fi-focused, has no Zigbee router role and does not support HomeKit, so the Gen4 fits multi-protocol homes better.

Are the size and load ratings the same on both?

Essentially yes. Both are among the smallest relays available at roughly 29 x 34 mm, rate 8A, require a neutral wire, and provide dry and wet contact modes with a 3-year warranty. Neither includes energy monitoring, so the choice comes down to protocols, not power handling.

Who should buy the Shelly 1 Mini Gen4?

Buy the Shelly 1 Mini Gen4 if you want Apple HomeKit support or plan to lean on Zigbee, since it doubles as a Zigbee router. It is the future-proof choice for a mixed Wi-Fi and Zigbee smart home in a tight switch box.

Who should buy the Shelly 1 Mini Gen3?

Buy the Shelly 1 Mini Gen3 if you want the lowest price and only need Wi-Fi control with Alexa, Google Home, SmartThings or Home Assistant. It is a proven, tiny relay for garage doors, sprinklers and other low-power DIY projects.
