1 Channel 5V 12V ZigBee Smart Relay Switch,Adjustable Selflock and Momentary Working Mode,DIY Smart Home (ZigBee Hub Required)

I took a punt on this as the first ZigBee relay in my home assistant setup. it works instantly with ZHA . 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.

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.

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.

Ok, it's a quite big when compared to the usual Zigbee/Zwave devices but hey, it's cheap and works. I use a Hubitat system and it had the correct drivers already installed ready to use, such an easy setup, I am impressed. I used it to turn my halloween monsters on and off to scare people.

This is a fabulous little ZigBee board. It's basically a changeover relay with brains. Works perfectly with my Homeassistant/ZHA/Sonoff-tasmota gateway setup. Though it does report to HA as a light, this can be changed by setting up a template switch as a wrapper around it. I did this as my board is controlling a dehumidifier - not a light. What you see is what you get. The board and a tiny little instruction sheet. Only interested in the wiring diagrams and microswitch functions, as I'm not doing anything with Alexa etc. All labelled correctly. Board accepts power through either a micro-usb or standard terminals. Power is not passed through to the relay circuit. It is an isolated dry contact. The antenna wire is good and can be uncoiled to a fair length. Powering up immediately puts the device in pairing mode. Discovery by the gateway was fast and painless. The default relay setting is what they call 'inching'. Found out that this is just momentary. When triggered, the relay side will flip for a second and then flip back. Good if you want control over things that rely on a momentary input. A microswitch on the board will change the mode to behave like a standard on/off relay, holding the position commanded until told otherwise. This is the mode I am using. Because this relay uses next to no power - if you have a device with a power adapter rated within the bounds of the board tolerance as I did (9V, DC), it is possible to splice this board between the device being controlled and the device power supply. Power the board using the dedicated power terminals with the device supply, but also run the device circuit through the relay. You'll need some tools, extra wires, a suitable junction box and some basic electrical knowledge to do this correctly. This gives a board that is always powered - also powering the device with its own adapter when the relay flips. We will see how it fares long term! If all good then I'll be grabbing a few more for other little projects.

This little box is open ended enough to provide full access to its relay terminals (two way) and a momentary (pulse) or switch mode. It works well with Home Assistant using the Zigbee gateway. It will run off 5v (USB charger) or low voltage. And it works fine!

This works a reliably with my Home Assistant/Zigbee setup. As with most ZIgbee devices I did need to adjust its position to get a reliable signal. It is now being used to switch the central heating boiler on an off in conjunction with house thermostats. I'm powering it by USB as this was the easiest for the location of the boiler.

I purchased this 1 channel ZigBee relay switch to turn on and off my 12v inverter - connecting up was super simple, just the 2 wires to my inverter and a micro USB cable for power. Home Assistant paired with the device instantly exposing an On/Off switch. I can now turn on/off my inverter via an automation or with a ZigBee button rather than having to walk across the other side of the room!! Brilliant device!
