Updated July 2026

Data from Amazon and official Shelly site.

2026 verdict

Cheapest route into one smart circuit? The Shelly 1 Mini Gen3 wins this relay comparison, taking price, an overheating safety cutoff and confirmed dry-contact and wet-contact modes. It is a tiny, Wi-Fi-only single-channel module (no Zigbee, and Apple HomeKit is not supported), while the Shelly 2PM Gen3 is a two-channel relay that adds built-in per-channel energy monitoring, HomeKit through Matter, a stronger owner rating and an interlock/cover mode for roller shutters. Pick the Shelly 1 Mini Gen3 for the smallest, lowest-cost single circuit; choose the Shelly 2PM Gen3 when you need two channels, energy metering or cover control.

Frequently Asked Questions

Which is better overall, the Shelly 1 Mini Gen3 or the Shelly 2PM Gen3?

The Shelly 1 Mini Gen3 wins this pairing on value: it is cheaper, tiny, and confirms an overheating cutoff plus dry and wet contacts. The Shelly 2PM Gen3 is the stronger buy if you need two channels, energy monitoring, HomeKit via Matter or a motorized cover mode.

What is the biggest difference between the Shelly 1 Mini Gen3 and the Shelly 2PM Gen3?

Channels and ecosystem reach. The Shelly 1 Mini Gen3 is a single-channel, Wi-Fi-only relay with no Apple HomeKit, while the Shelly 2PM Gen3 is a two-channel relay that adds Matter (and HomeKit through it), per-channel energy monitoring and a cover mode for shutters.

Does the Shelly 1 Mini Gen3 work with Apple HomeKit?

No. The Shelly 1 Mini Gen3 does not support Apple HomeKit and is Wi-Fi only. The Shelly 2PM Gen3 supports Apple HomeKit through Matter, alongside Alexa, Google Home and Home Assistant.

Which one measures energy usage?

The Shelly 2PM Gen3 has built-in per-channel power metering across its two circuits. The Shelly 1 Mini Gen3 does not include energy monitoring; a Shelly PM model is the option for metering a single circuit.

Who should buy the Shelly 1 Mini Gen3?

Budget-minded DIYers who want the smallest, cheapest single-channel Wi-Fi relay to hide behind a switch or inside an appliance, with dry and wet contacts for garage doors, sprinklers and shutters. It requires a neutral wire and skips Zigbee, Matter and HomeKit.

Who should buy the Shelly 2PM Gen3?

Buyers who need to control two circuits or a roller shutter, want per-channel energy monitoring, or want Apple HomeKit through Matter. The Shelly 2PM Gen3 covers a broader ecosystem than the Wi-Fi-only Shelly 1 Mini Gen3.
