SwitchBot Relay Switch 1 Review: A Versatile Dry Contact Relay That Excels at Garage Doors

A compact Wi-Fi and Bluetooth relay that runs on almost any power source and shines at automating garage door openers, if you can get past the manual.

The verdict

The SwitchBot Relay Switch 1 is a small dry and wet contact relay that buyers most often wire into a garage door opener or similar low-voltage trigger circuit, and it consistently earns praise for working across a wide range of power sources and integrating smoothly with the SwitchBot ecosystem, Matter, and voice assistants. Its dry (isolated) contact design is a standout advantage over similar relays for anyone wiring into sensitive automation circuits. The most common friction point is a manual that reviewers describe as hard to follow given the device's flexibility, and a handful of buyers ran into ecosystem incompatibilities like using it with a Zigbee-only hub, which it does not support. For garage doors, gate openers, and similar dry contact automation, it is a well-reviewed, adaptable pick.

Best for
  • Garage door and gate opener automation
  • Low-voltage dry contact circuits
  • Matter and SwitchBot ecosystem users
  • DIY smart home automation

Pros

  • Dry (isolated) contact output, ideal for garage door and gate automation
  • Works with a wide range of power sources, both AC and DC
  • Matter compatible alongside Google Home, Alexa, Apple HomeKit, SmartThings, and Home Assistant
  • Compact size fits tight installation spaces
  • Wireless switch mode and power-off memory
  • Overheating protection included

Cons

  • Printed instructions are hard to follow given the device's many wiring options
  • Wi-Fi and Bluetooth only, no Zigbee or Z-Wave support
  • A few buyers reported Wi-Fi compatibility issues on WPA3-only networks
  • No energy monitoring or physical on/off button
  • No overvoltage, overcurrent, or overpower protection, and no OTA updates

Who is the SwitchBot Relay Switch 1 for?

This relay is built for anyone who needs to add smart, voice-, and app-controlled triggering to a circuit that expects a clean dry contact pulse, most commonly a garage door opener or similar gate motor. Its support for AC (100-240V) and DC power, along with dry contact and wet contact modes, gives it flexibility to wire into a wide variety of existing setups, and its compact size lets it tuck into tight spaces like inside a garage door opener housing. Buyers who want it to slot into the Matter smart home standard, or to extend a SwitchBot Bluetooth mesh, also find it useful beyond pure switching duty.

What buyers love

The clearest theme is garage door automation done well: buyers describe wiring the relay's dry (isolated) contact output into garage door openers and gate motors and getting reliable remote and voice-triggered operation, matching its dry-contact-mode support. Reviewers repeatedly highlight how many different power sources it accepts, from low-voltage DC to standard AC, which the item's AC and DC power support confirms, and several mention successfully using it with Matter to bring the relay into their broader smart home setup regardless of ecosystem. Wireless switch mode and power-off memory also come up as practical touches that keep the relay behaving predictably.

What to know before you buy

The most common complaint is the printed instructions, which reviewers describe as too small or too thin given how many wiring configurations the relay supports, so budgeting extra time for setup helps. It has no Zigbee or Z-Wave radio, only Wi-Fi and Bluetooth, and at least one reviewer was misled expecting Zigbee hub compatibility, so it is worth confirming your hub uses Wi-Fi, Bluetooth, or Matter rather than Zigbee. A couple of buyers also ran into Wi-Fi compatibility snags with certain router security modes (like WPA3-only networks), though SwitchBot support was reported as responsive. It also lacks energy monitoring, an on/off button, over-the-air updates, and protections beyond overheating (no overvoltage, overcurrent, or overpower protection).

Is the SwitchBot Relay Switch 1 worth it?

For dry contact automation jobs like garage doors and gates, the Relay Switch 1 holds up well against similar relays thanks to its isolated contacts, broad power-source flexibility, and Matter compatibility across Google Home, Alexa, Apple HomeKit, SmartThings, and Home Assistant. Budget-friendly and versatile, it is worth it for buyers willing to work through a dense manual, though anyone specifically needing a Zigbee device or energy monitoring should look elsewhere.

Frequently asked questions

Can the SwitchBot Relay Switch 1 control a garage door?

Yes, its dry contact mode provides an isolated trigger connection that matches how most garage door openers and gate motors expect a remote signal, and this is the most common use case reported by buyers.

Does the SwitchBot Relay Switch 1 work with Zigbee hubs?

No, it connects over Wi-Fi and Bluetooth only. It does not support Zigbee or Z-Wave, so it will not pair with a Zigbee-only hub.

Is the SwitchBot Relay Switch 1 Matter compatible?

Yes, it supports Matter, along with direct integrations for Google Home, Alexa, Apple HomeKit, Samsung SmartThings, Home Assistant, and IFTTT.

What power sources does the SwitchBot Relay Switch 1 support?

It supports both AC power (100-240V) and DC power, and buyers report successfully running it from a variety of voltage sources depending on their wiring setup.

Does the SwitchBot Relay Switch 1 have energy monitoring?

No, this model does not track power consumption.
