Candeo Zigbee 2-Gang Switch Module | Compatible with Home Assistant & SmartThings Home System | Dual-Channel Smart Remote Lighting Control | LED & Incandescent Bulbs | Retrofit | Monitor Energy Use

I have a light fitting with 8 incandescent bulbs which would cost a fortune to replace with smart bulbs and wouldn't look as good, so this device is a great low cost work around. Note that not all Zigby relays are compatible with Phillips Hue but this one is so great for that use (though not "official" so support could theoretically be removed in the future). Important things to note:The manual sates that these only work with retractive switches and NOT work with traditional rocker switches or dimmer switches. However I found this to be the exact opposite case in my setup. Retractive switches were only keeping the lights on while held down, and toggle switches worked fine (without dimming). Traditional dimmer switches have no effect at all. They will still work with your smart setup even with no physical switch attached.Also, these do not include any lengths of wire so if you don't have any spare you will have to cut/strip your existing wires to splice this device into the circuit.Should fit into most UK junction boxes, but only if your switch body is not too deep (I don't think th UK ones are as deep as the EU ones which are predominat in the marketing).It states that if you don't use a neutral wire you will likely need a bypass on the first light, however fortunately my 8 bulbs drew enough power so it wasn't needed.

I previously bought a Tuya based product at half the price of this. Needless to say, it paired but it didn’t show any signs of working or dimming.I ordered this as a replacement and it worked first time.Paired to my Ikea zigbee hub, it also shows in HomeKit and Alexa.The only problem I had was my led festoon it was controlling didn’t turn entirely off. It would look off in daylight, but the leds would glow slightly in the dark. (The dimmer is rated at 400 watts and my entire festoon is about 30) it needed a greater load on the dimmer, so I bought (from this company) an LED Bypass (essentially a 1.4watt resistor, I didn’t measure the value)The dimmer is in an IP65 junction box on my garden fence, about 15M away from my hub in the middle of the house. It has a short cable antenna hanging off the dimmer, which will help with the zigbee signal over distance.So far so good, I’d highly recommend.

Very small size, easy to pair to my hubitat not sure about other devices. Would not switch off light unless I used a bypass which is an extra. Reading about them afterwards seems without a neutral you need it 100 percent. I would have given it 5 stars if the bypass came with it.

Simple to use, just be careful placing them behind a faceplate even with 35mm deep backboxes. You will need retractive switches which you can either buy as finished product or you can make your own using any grid system. Which makes the whole flexibility of using these so much more convenient. I combined these with retractive switches, paired with hue hub and also hue remotes for each room so I can control the scenes achieved through dimming and turning on certain LED lighting accents works brilliantly so far.

These worked well for my use case. Fit well behind a UK switch providing there are not too many other wires to accommodate

This is a good device, and easy to work with. The screw terminals are decent quality, the LED tells you what you need to know and getting it paired is easy. It's compatible with Hue (it comes up as an on/off light), Openhab, HA etc.My problem with it was the S1 input. Per the wiring diagram, you can supply this with switch Live - it'll turn on when it gets this, or off when it's gone. This works fine if the device is really close to a simple rocker light switch (it is of course designed to be mounted behind such a switch). However, if the wire from the switch to the device is even just a couple of feet long, the electrical noise on it seems to confuse the device. It then won't see the switch being turned on or off. This doesn't work in my situation, and might not if you're putting it into a ceiling rose or similar.I didn't try if you switch between COM and S1 (without direct live) - my suspicion is this will work fine, but just no use in my particular use-case.All in all, it's a good switch, and it'll work beautifully for many, but not for me.

Bought these for LED spotlights that have a variable 240V input. Works really well. Nice you can also set the minimum light level. Setup very easily into existing Philips Hue system.

Works well with all my dimmable bulbs and lamps. Pairing with Hue or Smartthings flawlessly. If you need and traditional dimmable swith as well, you may also consider the dimmable switch with faceplate model. They did the same good job, save you a retractive switch and the prices are the same.
