Verified AliExpress match to the Shelly Pro Smart Relay

The listing matches the Shelly Pro 1PM spec sheet on the key points, single channel, 16A, power metering, Wi-Fi and LAN. However, GreatScott! referenced 'Shelly Pro' generically in the video, so the exact variant reviewed cannot be confirmed with certainty. The 1PM is the most commonly discussed Pro-series relay with metering, making it the most likely match, but buyers should verify against their own project requirements.

The Shelly Pro 1PM supports native integration with Amazon Alexa and Google Home through the Shelly app. Apple HomeKit is not natively supported on Pro-series hardware, but can be bridged via Home Assistant or third-party homebridge plugins. If HomeKit is a hard requirement, confirm your integration method before buying, the hardware itself does not change between purchase channels.

The Shelly Pro 1PM is rated for 110-240V AC, so it is compatible with both North American 110V and European 220V mains. The 16A switching rating applies across that voltage range. Always verify the printed rating label on the physical unit matches the listing spec before installation.

The Shelly cloud app and local API work globally with no mandatory subscription. Local control over LAN functions without any cloud connection, which is relevant if you run Home Assistant or similar. Shelly's cloud scenes and remote access are free at the time of writing, though Shelly reserves the right to change cloud terms.

At $70.37, this listing is roughly 55-100% above the $35-45 typical retail price for a Shelly Pro 1PM. AliExpress markups on branded smart-home hardware are common when a third-party seller buys from distribution and resells without volume pricing. Check Shelly's official store, Amazon, or regional distributors before committing to this listing.

Shelly publishes a ±1% accuracy spec for the Pro 1PM's energy metering at rated load, which is suitable for household appliance monitoring and basic energy logging. The GreatScott! video covered Shelly as a cost-effective automation platform rather than a precision metering tool, for billing-grade accuracy you would need a certified utility meter. For home dashboards and automation triggers, the 1PM's metering is considered reliable by the community.
