SwitchBot Smart Relay Switch 2PM, Power Monitoring, Smart Relay Module with Built-in Bluetooth Repeater, Wi-Fi&Bluetooth Switch Works with Alexa/Apple Home/Google Home/Matter Hub Required, 2.4GHz, 16A

Fantastic Addition
This Apple Home-compatible relay is a fantastic addition for smart home enthusiasts. Its ability to be programmed via the Switchbot application offers impressive flexibility, allowing for simple dry contact operation (NO), timed functions, or single pulses. With two independent dry NO contacts, you can configure each one separately to suit your specific needs. It’s a versatile and reliable solution for integrating various devices into your Apple Home ecosystem.

loved it but not easy installation
The price is £26.99 at the time of review and while it is good value for money, it can be lower compared to other similar products on Amazon. Glad I ordered as it has been useful, but maybe a bit of mixed feelings. This product is suitable for those who want to automate two circuits—like lights and fans—without rewiring everything. Its main functionalities include remote control via Alexa/Google Home, energy monitoring, and creating custom automation scenes through the app. You can even pair it with sensors to trigger actions like turning on lights when motion’s detected.What I loved most was how the build quality is solid—the V0 flameproof casing feels sturdy, and the 16A rating handles heavy loads without heating up. The ease of use is decent once you’re past the initial setup; the app’s energy graphs helped me spot which appliances were draining power. On the flip side, the instructions are vague—I had to watch YouTube tutorials to figure out wiring, especially since my older switch box lacked a neutral wire. Also, the 2.4GHz Wi-Fi requirement caused hiccups until I moved my router closer.If you’re intending to buy this, then I’d advise to consider whether your switch box has a neutral wire and enough depth—mine barely fit, and I had to adjust the wiring. Double-check compatibility with your smart home setup (Matter support’s great, but some hubs might need tweaking). The copper-nickel contacts are reliable, but if you’re not comfy with basic electrical work, maybe get a pro to install it. For the price, the control are neat, though the app could be more intuitive. If your priority’s long-term energy savings over plug-and-play simplicity, this’ll do the job.

Versatile and integrates into many systems
This is a two “gang” relay switch that is designed to be small enough to fit in the back box behind your light switch. There are two issues for me with this, my back boxes are thin and there is not enough room in them and secondly this relay requires the negative on the power supply when my switch back boxes only have two wires the supply and switched return. If you don’t have the negative wire you either need to rewire or install the relay back in the lighting circuit in the loft or under the floorboards where you can access the circuit including the negative. You may have to change things around a bit depending on loops in your wiring. You can still use the old wiring to the switch. This negative wire is commonly required and this is not unique to this relay.Once you actually get it installed it needs joining to the network and there is no explanation included of how to do this. I got the SwitchBot app from the Play Store and set up an account in order to set the relay up then you have to load the service/integration/helper to run it from your Alexa or Google etc.As I don’t want to control the relay from the SwitchBot app (I have too many other control apps) I need to integrate it in to my Home Assistant. To do this I needed the SwitchBot bluetooth integration.This particular relay benefits from having two relays built in so you can control two lighting circuits just like a double gang light switch.If you have other Switchbot devices you can form a bluetooth network where the devices work as repeaters, a sort of bluetooth version of zigbee.

Ho installato lo SwitchBot 2PM per controllare gli avvolgibili elettrici di casa e ne sono pienamente soddisfatto. Il modulo supporta il doppio canale (2 relè indipendenti), perfetto per motori tapparella con comandi salita/discesa separati.Il cablaggio richiede:Alimentazione 230V su morsetti L e NUscite motore su OUT1 e OUT2Comandi manuali (opzionali) collegabili su S1/S2È compatibile con impianti a pulsanti e interruttori e include funzione i per impedire l’attivazione simultanea di salita e discesa (fondamentale per i motori). Controllabile via app SwitchBot, Alexa, Google Home e Siri Shortcuts. Inoltre, supporta programmazione oraria e monitoraggio energia (grazie al chip 2PM).Un’ottima soluzione smart, sicura e compatta per chi vuole automatizzare tapparelle senza centraline complesse.Ecco uno schema di cablaggio per utilizzare l’SwitchBot Interruttore WiFi 2PM con avvolgibili elettrici, ideale per motori con comandi separati di salita e discesa:L (fase)N (neutro)O1 salita motoreO2 discesa motoreS1 pulsante salitaS2 pulsante discesa

SwitchBot ist eine super einfache Relais-Schalter Lösung für automatische Anwendungen. Wir nutzen es jetzt in Verbindung mit einem Temperatursensor von SwitchBot, um unser Oberlicht in der Ausstellung automatisch auffahren zu lassen, wenn oben die Temperatur über 24° ansteigt. Das spart Energiekosten und ist sooo einfach mit diesem Relaisschalter. Es paßt mit in die Unterputzdose rein und ist einfach verdrahtet und funktioniert einfach! Ohne daß es schwierig wäre es zum Laufen zu bringen. Die App ist sehr nutzerfreundlich und wenn man mal etwas nicht genau weiß, kann man auch Chat gpt dazu fragen.Ich bin sehr begeistert und werde mir noch einige andere Bots von SwitchBot holen. Das ist perfekt! Vielen Dank an das Entwicklerteam 😉 ihr baut top Teile!
