Aqara Smart Light Switch (No Neutral, Single Rocker), Requires AQARA HUB, Zigbee Light Switch, Remote Control and Smart Home Automation, Compatible with HomeKit, Google, Works with Alexa, SmartThings

No neutral, requires a hub – but fantastic quality.
I had some old light switches that controlled my dining table light, and ceiling lights in the lounge that I wanted to incorporate into my smart home. Instead of adding unnecessary traffic on my WiFi network by adding a bunch of WiFi light bulbs, I added a paid of these to the light switches instead. These were easy to swap out, look amazing and operate flawlessly.The pros of doing it this way:* Much lower cost that replacing all the light bulbs with smart light bulbs* Doesn’t add unnecessary load on a crowded WiFi network* Maintains the light switch functionality as before – toggles the lights on and off as normal* Avoids issues that might occur if you turned off a light switch with smart bulbs – you’d lose control over them. This problem doesn’t exist in this caseThe cons:* Zigbee device and requires an Aqara Hub – I would recommend the M3, although anything from them will work. You can also use third party Zigbee hubs, and integrate into Home Assistant for example* No neutral comes with a price premium. Ouch!

Insane Value, High Polish, Easy Open Integration
I very rarely write reviews, but I came back to give these five stars because it’s absolutely criminal that their average rating isn’t higher. Here’s the tl;dr: if you have no-neutral wiring in your home and you’re sick of the entire internet smugly telling you that you simply MUST pay a king’s ransom for overpriced, decade-old Lutron Caseta hardware if you want your lights to work, this is what you’re looking for. The polish and build quality is equivalent (I’ve used both and Caseta is moving away from no-neutral, so their remaining switches in that area are starting to look pretty dated while still costing an arm and a leg). These give you the same thing while costing a third less per switch, not requiring their hub if you already have another, and they frequently go on sale.As you can probably tell, I’ve been really frustrated with this “luxury” smart home market where every brand is ignoring existing standards in favor or separate, proprietary walled gardens where you need five different redundant hubs and every feature is an add-on charge in practice. My generic, privacy-focused solution to this has been to search for brands that use Zigbee connectivity, and connect them to my Home Assistant hub instead of their own. Some brands try to stop you from doing this, Aqara does not (aside from their door lock, which needs the hub for security reasons). It was even easier than I expected to install these and set them up in Zigbee2MQTT. But they surprised me by also including literally everything you need (fancy screwless faceplate, screws for both the switch and the underside of the plate, wire nuts) and having MORE features than advertised, even when I installed their switch into another system instead of theirs (many brands artificially prevent other Zigbee coordinators from accessing their more advanced features).I was able to choose whether the indicator light activates when the switch is on or off, decide what it should do after a power outage, choose between quick response mode and anti-flicker mode, and most impressively, choose between it working as a literal switch or decoupling from the circuit, leaving that always-on, and controlling smart lights through the zigbee connection instead. That last one is hugely useful for a lot of setups, and is something I thought I had to pay twice as much for Inovelli Blues to get.Lastly, I don’t really get people complaining about how the button function feels. It’s a single rocker switch, and it feels like you’d expect one large single button to feel. I actually kind of like how light the press is. The build quality looks solid to me, and if you use their included plate, the whole thing looks really clean. The plate is slightly smaller than an average switch plate, so it looks really cute while still covered the whole switchbox without any issue

Love this switch!Retrofits into old homes with no neutral has simple one paddle operation so it fits in with decor and you don’t need to give guests a 30 minute course on how to use it when they visit for the first time.Switches quickly locally and via zigbee and always reliableIt’s a little bulky so it might be a tight squeeze in some boxes

Es un buen producto, que en compañía del Hub M2 de Aqara, funciona de maravilla, SIN NEUTRO NO FUNCIONA, así que revisa tu instalación antes de pedirlo para que tomes tus precauciones. En mi caso, solo fue alimentar un cable extra, el detalle es que las tuberías de mi hogar estaban colapsadas, al final se pudo instalar sin problemas.

J’ai recherché pendant un certain temps un interrupteur double certifié ETL pour le Canada. Après plusieurs déceptions avec des interrupteurs wifi qui prétendait être certifié mais ne l’était pas en réalité. J’ai décidé de regarder pour un interrupteur ZigBee, malgré la dépense additionnelle pour le gateway.Avant d’acheter, j’ai consulté les commentaires, et un de ceux-ci expliquait que cet interrupteur fonctionnait avec Home Assistant avec un gateway ConBee II. L’utilisation du gateway ConBee II me semblait une solution supérieur au Hub Aqara, étant donné qu’il est universel et donc supporte plusieurs marques d’équipements ZigBee. J’ai donc décidé de valider le tout en achetant l’interrupteur double WS-USC04 et un gateway ComBee II.J’ai branché le gateway ConBee II sur mon Home Assistant, un Raspberry Pi 4, et en seulement quelque secondes il est apparu dans les intégrations (voir capture d’écran #1), la raison étant simple, l’intégration ConBee est natif dans Home Assistant. Par la suite, j’ai fait un montage avec une extension électrique, pour tester l’interrupteur. À partir de l’intégration ConBee de Home Assistant, j’ai recherché l’interrupteur et il s’est ajouté et configuré de lui même. Il est parcontre détecté comme étant un interrupteur LUMI et pas Aqara.PS. Pour que l’interrupteur soit en mode ‘connexion’, il suffit de maintenir les 2 bouttons de l’interrupteur enfoncé, pendant quelque seconde, jusqu’à ce que les lumièrs de des boutton clignotent.Pour:- Un des rare interrupteur double certifié ETL.- Facile d’intégration.- Les équipements ZigBee agissent comme répéteur et ainsi ont une porté supérieur au wifi.- N’encombre pas votre réseau wifi étant donné qu’il utilise son prope réseau sans-fil.Contre (je devais en trouver au moins un):- Nécessite un GateWay, donc une dépense additionnelle qui équivaut au prix d’un interrupteur.Malgré la dépense additionnelle pour le GateWay, qui n’est pas vraiment un point négatif en soit, étant donné que j’ai maintenant accès à une multitude d’équipements ZigBee, je suis très satisfait de mon achat. Il reste à l’installer et tester sa robustesse dans le climat du Québec.À suivre…
