The Shelly 1 Gen4 covers 3 years against 1, takes over-the-air updates, and adds a Zigbee mode where it can act as a router, while the Switchbot Relay Switch 1 is Wi-Fi and Bluetooth only and lists no OTA updates. What the Switchbot Relay Switch 1 does keep is wireless switch mode and power-off memory, plus a lower price. Both support Matter, Alexa, Google Home, Apple Home, SmartThings and Home Assistant, both offer dry and wet contact modes, and neither monitors energy or lists overvoltage protection. Choose the Shelly 1 Gen4 for the longer warranty and Zigbee, and the Switchbot Relay Switch 1 if you already live in the SwitchBot app.

What the differences mean

Warranty

The Shelly 1 Gen4 carries a 3 year warranty and the Switchbot Relay Switch 1 carries 1 year. For a relay buried behind a wall, the longer cover is the difference you would notice.

Zigbee

The Shelly 1 Gen4 can join a Zigbee network through a hub and then repeats the signal for other devices. The Switchbot Relay Switch 1 has no Zigbee, so it will not pair with a Zigbee-only hub.

Firmware updates

The Shelly 1 Gen4 lists over-the-air updates, and the Switchbot Relay Switch 1 does not. Over the years of a wall-mounted relay, that decides who fixes bugs and adds protocol support.

Wireless switch mode and power-off memory

The Switchbot Relay Switch 1 lists both. Wireless switch mode lets a wall switch trigger scenes while the relay keeps the light on, and power-off memory restores the last state after an outage. The Shelly 1 Gen4 does not list either.

Power input

The Shelly 1 Gen4 takes 12 V or 24-48 V DC, while the Switchbot Relay Switch 1 is listed at 10 A on DC. Both take 100-240 V AC at 16 A and both need a neutral wire.

What owners say

Owners of both relays end up using dry contact wiring for the same jobs, garage door openers and gate motors triggered from a phone, a voice assistant or Home Assistant, and both groups find the wiring the part to plan for. Shelly 1 Gen4 owners single out easy Wi-Fi setup, schedules that run on the device and keep working through an outage, and reliable Home Assistant integration, while they warn that Zigbee pairing can be fiddly, Hubitat being the example, and that the module is a tight fit in a crowded box. Switchbot Relay Switch 1 owners single out the range of AC and DC power sources it accepts and how well it slots into Matter and the SwitchBot ecosystem, and they mention printed instructions that are hard to follow, a Zigbee-only hub that will not work with it and a few Wi-Fi snags on WPA3-only networks.

Price history compared

Every price change of both, in the same store, so the gap between the two lines is what one costs more than the other.
