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

Works as intended, the schematics provided contain one error (wires from L1/L2 going to the lights should be coloured in red). This proved to be the biggest stumbling block, from then on, installing was ok, fits in a standard box, connected to the Zigbee network after a quick reset. Responsive.

Works perfectly with led bulbs, fits into standard back box and integrates seamlessly with Philips Hue bridge. Only downside is that it does not appear in Apple HomeKit.

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.

Works exactly as expected. Paired instantly to a Phillips Hue Hub and can be controlled in HomeKit via this. Installed in a waterproof enclosure to make 8x 4w outdoor LED downlights smart. If using selectable wattage downlights, ensure they are all on the same wattage - as if they are different wattages it causes flickering.

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.

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.

After struggling with other cheaper brands I ended up giving in and buying this. Incredibly straightforward to wire up and fully compatible with Philips hue and Alexa. Yes, it’s more expensive than others on the market but it’s worth it for how easy it is to setup.

Very good all round control units. Had another manufacturer installed which kept needing resetting. Existing didn't connect reliably through ceilings with fire rating boards. These units work perfectly, including very smooth dimming to lower lux levels. Alexa controlled, plus connects to Philips hub. I would recommend these units, I've bought three of them already!
