It identifies as a Light but works fine as a relay. I originally used it to control my wife's fairy lights in the garden from Home Assistant. As they have been completely problem free, I invested in 3 more. One to drive a different set of battery driven garden lights , and another to switch my central heating boiler on and off (+1 spare) as far as I know (other opinions are available) this is the only DC powered ZigBee relay to act as a router (repeater) meshing other ZigBee devices together The adverts can be confusing so I'll try and clarify setting it up. The unit has 2 options to power up the control side - option 1 is a micro USB connection (5V) on the end. Option 2 is a pair of screw terminals (+ and -) on the side which can be between 7 and 32V either DC or AC apparently (I haven't tested these). The "load" is connected by 3 screw terminals on the side of the unit. COM is COMMON i.e. mains live volts in , the other 2 pins are NO (normally open) and NC (Normally closed) which is standard for an SPDT (single pole double throw) switch. on the top of the unit are 2 push buttons. one is for pairing and reset , the other switches operational mode (momentary action or hard switched) . The variants I bought also have 433MHz receivers built in for local remote control instead of ZigBee, this is not ZigBee protocol on 433MHz as some of the adverts imply. this works with EITHER a standard zigbee hub OR 433Mhz (but a separate 433MHz transmitter unit is required to do local control. Very happy customer (must be I bought 4!) Hope this helps someone out there. Review: Excellent - great price, easy setup and fast response (shows up as a light under HUE) - Just what I was looking for: a straightforward Zigbee relay. I positioned it next to my HUE bridge and plugged it into a 5v USB supply via the micro-USB connector on the side. Then I scanned for new lamps on the HUE app and quite quickly the relay popped up as "ONOFF Light" at which point I could control it no problem. My HUE bridge is also connected to HomeKit, so the relay shows up under the Apple Home app and can be controlled that way too. One press on the 'mode' button on the device puts it into momentary mode which makes it output a ~1sec pulse each time you command it ON from the app, which is useful to trigger a garage door opener for example. ## Features - Wide compatible and easy setup,Zigbee hub is needed.1 Channel Zigbee Switch is compatible most brand Zigbee Gateway.Compatilbe with Home assistant 2mqtt.5V 12V 24V low voltage zigbee on/off controller,DIY Smart Garage Door Gate opener - ZigBee3.0 Protocol, One-tap Pairing: Adopts ZigBee3.0 protocol, you can quickly add it to SONOFF ZBBridge, getting them paired via a single tap on the app - Voice Control,works with desertcart Alexa and Google home devices for complete voice control, remote control and Intelligent timing.

I positioned it next to my HUE bridge and plugged it into a 5v USB supply via the micro-USB connector on the side. Then I scanned for new lamps on the HUE app and quite quickly the relay popped up as "ONOFF Light" at which point I could control it no problem.

One press on the 'mode' button on the device puts it into momentary mode which makes it output a ~1sec pulse each time you command it ON from the app, which is useful to trigger a garage door opener for example. ### ⭐⭐⭐⭐⭐ Works well *by M***B on 22 December 2025* Works well and has allowed me to remote control my pellet boiler at last. Note default seems to be just transient operation but pressing the one of the buttons changed this to latching mode which is what I need. The other button lets you switch on, switch off locally, but zigbee works fine. Instructions are rubbish. I have order a second as either a spare or for another use if I find I need one. ## Frequently Bought Together - MHCOZY Smart Home Dry Contact Zigbee Relay Switch, Remote Control Zigbee Switch for Light Garage Door, Compatible with Alexa Google Home,Zigbee hub Needed (1CH) - THIRDREALITY Zigbee Smart Garage Door Tilt Sensor, Adjustable Sensitivity Levels, 2-Year Battery Life, Zigbee Hub Required - THIRDREALITY ZigBee Smart Plug 4 Pack with Real-time Energy Monitoring,15A Outlet, Zigbee Repeater,ETL Certified,ZigBee Hub Required,Work with Home Assistant,Compatible Echo Devices and SmartThings --- ## Why Shop on Desertcart? - πŸ›’ **Trusted by 1.3+ Million Shoppers** β€” Serving international shoppers since 2016 - 🌍 **Shop Globally** β€” Access 737+ million products across 21 categories - πŸ’° **No Hidden Fees** β€” All customs, duties, and taxes included in the price - πŸ”„ **15-Day Free Returns** β€” Hassle-free returns (30 days for PRO members) - πŸ”’ **Secure Payments** β€” Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** β€” Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.in/products/297880295-1-channel-5v-12v-zigbee-smart-relay-switch-adjustable-selflock](https://www.desertcart.in/products/297880295-1-channel-5v-12v-zigbee-smart-relay-switch-adjustable-selflock) --- *Product available on Desertcart India* *Store origin: IN* *Last updated: 2026-04-25*
