Discontinued. The manufacturer no longer sells this one new, so a retailer link here can land on remaining stock, a used or refurbished unit, or a successor model - check what the listing is before buying.

Newer version available. This model is succeeded by the Shelly 1 Gen4 - worth a look before buying this one.

Owner’s hands-on review 4.5/5

Very reliable and easy to install, but I prefer the Mini for lights

My only real complaint with the Shelly Plus 1 is that it’s a little harder to fit inside the electrical box. If I’m only controlling lights, I prefer the Mini. Otherwise, it’s great: very reliable and easy to install.

Quick verdict

Shelly has discontinued the Plus 1. The Shelly 1 Gen4 is the current version of the same relay and the one Shelly's US store actually sells (the Gen3 is not carried there). The Shelly Plus 1 is the Swiss Army knife of smart home relays - tiny enough to fit behind a switch plate, powerful enough to handle most single-load switching. Full local control via HTTP, MQTT, or native HA integration. You do need to be comfortable with basic wiring.

Standout: Tiny Wi-Fi relay with full local API - hides behind any existing switch plate.

What changed for this product

Sep 8, 2026 · Added

Shelly 1 Gen4 and 2PM Gen4 now have product pages

The guides have named these two as the parts to buy since Shelly discontinued the Gen2 Plus line, but neither had a page, so the only clickable relay link in those sentences still went to the superseded Plus model. Both now have pages with dated sources: the Shelly 1 Gen4 (potential-free contacts, no metering, $27.99 for the UL-certified US SKU) and the Shelly 2PM Gen4 (two metered channels, 10 A each and 16 A total, $39.99 - less than the Plus 2PM cost). Each ships in a Matter-over-Wi-Fi profile and switches to Zigbee with five presses of the device button, one radio at a time. I have run neither, and both pages say so.
Sep 7, 2026 · Superseded

Shelly has retired the Plus generation; Gen3 and Gen4 replace it

Shelly’s US store now marks the Plus 1, Plus 1 UL, Plus 2PM, Plus Plug US and the original Wall Display as discontinued, each with a named successor: the 1 Gen3 and 1 Gen4, the 2PM Gen3, the Plug US Gen4 and the Wall Display X1i. The product pages say so and link forward. Plus units you own keep working and keep their local API.
