Best experience yet for installation and connection
Very compact and great documentation, much easier to install and get it recognised than other similar brands I've experienced. In app experience was also far better than competing Matter relays. Has performed flawlessly and linked up with Apple Home and Alexa without an issue. Can't share a photo as is behind the light switch but have not had to take it out since installed almost 2 months ago. Great for those looking for a compact switch to control two lights with existing wall switches and wiring.

Great smart relay, just make sure you have the WiFi coverage and space behind your wall switches
I have several SwitchBot relays wired up behind wall switches to turn noisy extractor fans off at night and back on in the morning. I wish the 2PM relay had come out in the beginning as they allow me to control both the fan itself and the boost function normally linked to the lights with only one smart device.Performance wise they haven't missed a beat operating a couple of times a day (using schedules in the SwitchBot app) except when the WiFi strength is patchy, which can be an issue in a metal box, in the wall, behind a switch!Wiring them up required a little more than basic knowledge of house electrics but actually fitting the relay was easy. Connection to the app was also straight forward, following the instructions.I had been using Switchbot Bots to do the same thing for 2 or 3 years, but the relay doesn't require batteries, is more reliable, quieter and if you have the space behind your wall switches (the relay is 16mm thick + a bit of room for wires), is invisible once installed. Shame this wasn't available 2 or 3 years ago.

Easy to install. Works well
This nice little gadget is easy to install even for a not specifically trained tinkerers. You'll need a couple of suitable wires and wago connectors though. Check supplied video instructions, if you are not sure.It is likely to fit the space available behind your wall switch, but check before you start to avoid undoing it just to make more room to put it all back together.

Matter enabled switch with Home Assistant
This was the first matter enabled switch I have installed. Item works perfectly, but took a bit of trial and error to integrate with Home Assistant. Now that I am more familiar with matter enabled devices everything is a little easier.

Game changer for old appliances
I have been trying out smart home devices for a while, and this Smart Relay Switch really feels like the last piece of the jigsaw. It is compact, matchbox-sized, but once installed, it seamlessly converts older devices into smart, voice-controlled devices. I could fit it easily behind an existing light switch without needing to rewire, and the whole installation took under 10 minutes.It also supports Matter, which means I can control it using either Alexa, Google Home, or Apple Home without any brand concern. Its built-in Bluetooth repeater also boosts signal strength on other smart devices within my house, which was a welcome bonus. But automation is where the fun begins, by using either Siri shortcuts, Alexa or even IFTTT, you can action specific devices and appliances to start/stop whenever you turn another device on/off.Overall, this is a brilliant, convenient smart home upgrade. If you'd prefer to make older appliances "smart" without needing to replace them or using an external hub, this is the answer.

Quite good but some flaws
Good price and works well. The cover is a little flimsy and the terminals just about fit a very short section of 2.5mm cable. Matter qr code doesn’t work with HomeKit or home assistant at least straight out the box. You have to use it in the switch bot app and assume you can then get it into your preferred platform but yet to figure that out.

Switchbot review
Need better instructions for UK customs as our fuse and electric is different. But amazing product would recommend it.

Zudem unterstützt er das Matter-Protokoll, was eine direkte Integration in Systeme wie Alexa, Apple Home und Google Home ermöglicht – inklusive Sprachsteuerung und smarten Automationen.Energie- und LeistungsmonitoringEin besonderer Vorteil dieses Modells ist die Möglichkeit, Energieverbrauch und Leistung der geschalteten Geräte präzise zu messen und auszuwerten. So lässt sich nicht nur steuern, sondern auch der Strombedarf beobachten und optimieren – ein nützlicher Beitrag zur Energieeffizienz im Haushalt.Zuverlässige Konnektivität und ZusatznutzenDer integrierte Bluetooth-Repeater verbessert die Reichweite und kann die Verbindung für andere SwitchBot-Bluetooth-Geräte im Netzwerk stärken. Die Einrichtung erfolgt über die SwitchBot-App und ist auch für technisch weniger versierte Anwender gut verständlich.Alltagserfahrungen:Im täglichen Einsatz lässt sich der Schalter intuitiv in Routinen und Zeitpläne einbinden, etwa zur automatisierten Lichtsteuerung oder zur geplanten Aktivierung von Haushaltsgeräten.

Correcto funcionamiento.
Se tenĂan dudas respecto al correcto funcionamiento del producto por los comentarios de otros usuarios, sin embargo tras instalar los 4 interruptores trabajan en muy buenas condiciones, preocupaba eñ alcance de la señal wifi y sin mayor problema, dos se instalaron en la primer plants cerca del router y dos en la segunda planta y con conexiĂłn muy estable todo el tiempo de momento tras una semana de uso.

DesconexiĂłn continua wifi
Se desconecta de wifi tras 10 minutos de conexiĂłn, continuamente, cada vez que te conecto. FATAL.

Una maravilla para quien quiere domótica fácil y que funcione de verdad
No soy precisamente un experto en electricidad y reconozco que al principio me daba un poco de respeto instalarlo, pero ha sido mucho más fácil de lo que pensaba. Las instrucciones están muy bien explicadas y, por si acaso, incluso hay vĂdeos muy Ăştiles que ayudan a entenderlo todo mejor. AsĂ da gusto.Lo estoy usando para controlar una luz desde la cama sin tener que levantarme y va genial. Puedo encenderla desde el mĂłvil o con Alexa, y hasta ahora no ha fallado ni una vez. Es una comodidad total, y si te gusta tener una casa un poco más inteligente, este aparato cumple con creces.Una de las cosas que más valoro es lo bien hecho que está. Se nota que han cuidado los detalles, desde la presentaciĂłn hasta lo estable que funciona una vez instalado. Llevo ya varios dĂas usándolo y no tengo ni una sola queja. Va rápido, responde bien, y transmite seguridad, que para mĂ es clave en este tipo de productos.En resumen: fácil de poner, Ăştil de verdad, y con ese punto de “te cambia la vida” que tienen los buenos cachivaches de domĂłtica. Me ha gustado tanto que estoy pensando en poner otro en otra habitaciĂłn.
