SwitchBot Smart Relay Switch 1 (2 pack) – Wi‑Fi & Bluetooth relay module with built-in hub
Product description
The essentials
If you’ve got older lights, fans, heating, or air conditioning controls and you don’t fancy rewiring, a smart relay module is one of the more practical routes to “make it smart”. The SwitchBot Smart Relay Switch 1 (2 pack) is designed to sit inside (or alongside) an existing switch box and let you control the connected device from your phone, plus voice control through supported smart home platforms.
What makes this kit stand out on paper is that it bundles a built-in hub and uses both Wi‑Fi and Bluetooth. That means remote control via smartphone when the network is available, but also local control via Bluetooth if the internet is down. It’s also described as Matter-compatible, which is a big deal for people who want fewer hoops when building or expanding a home automation setup.
Key features and what you’ll notice
The Smart Relay Switch 1 is a compact device intended to fit most switch boxes and outlets without rewiring. According to the information provided, installation is positioned as quick—around 10 minutes—so you’re not looking at a major weekend project just to add basic automation.
Control options are broad: - Wi‑Fi remote control through a smartphone. - Bluetooth local control if your internet connection drops. - Voice control via Alexa, Apple Home, Google Home, or SmartThings, with the Matter protocol supporting direct connection (and the note that SmartThings requires a compatible speaker).
It also includes a built-in Bluetooth repeater. The key practical implication is that it can help networking for up to 10 SwitchBot Bluetooth sub-devices, which is relevant if you’re thinking about sensors and other nearby Bluetooth add-ons rather than running everything over Wi‑Fi.
A second area to consider is automation. The description mentions custom smart scenes, including turning lights on when doors open or with motion (requiring a SwitchBot Sensor), and turning hallway lights off at a preset time. There’s even an example combining with a SwitchBot Meter to automate garden irrigation based on temperature and humidity. In day-to-day terms, this is the sort of setup where you can go from “I remember to switch things on” to “the house takes care of routine moments”.

Where it shines (and the limits)
This is the sort of smart relay you buy when you want to upgrade existing switches without tearing out wiring. If you’re aiming to control everyday items—lights, fans, heating, or air conditioning—by phone and voice, it matches that brief.
It also suits households that care about resilience. The “internet down” fallback to Bluetooth local control is a genuinely useful detail, because not everyone wants smart automation that stops the moment broadband misbehaves.
That said, a couple of limitations are worth being honest about. Matter compatibility is mentioned, but the exact experience can depend on your existing ecosystem—particularly if you’re already deep in one platform. Also, smart scenes that react to doors or motion mention a SwitchBot Sensor requirement, so don’t assume every automation works out of the box without adding sensors. And if you’re trying to automate something very niche, you’ll still want to double-check the relay approach fits your existing setup rather than assuming all devices behave the same.
Who it’s for (and who should be cautious)
It makes sense if you want a practical way to turn existing switch-controlled devices into something you can control remotely and by voice, while keeping installation fairly lightweight.
Worth considering if you’re planning to add Bluetooth devices and would like a repeater built into the system to help networking for up to 10 sub-devices.
It’s not for you if you expect every automation to work without extra sensors, or if you’re looking for a plug-and-play, no-install solution. This is a relay module that’s intended to fit within switch boxes/outlets, so the “old devices become smart” promise is tied to that type of installation.
Buying verdict
Is it worth it?
Worth considering if your priority is upgrading existing lighting or appliances with remote control, voice control, and some resilience when the internet is down—especially if you like the idea of Matter being part of the mix.
You may want to skip it if you’re starting from scratch with brand-new wiring and you don’t need a relay-style upgrade, or if you’re only after very basic control and would rather avoid the smart-home ecosystem steps that come with voice and Matter compatibility.
The 2-pack is also a sensible detail if you’ve got more than one switch you want to modernise at the same time—though do make sure you actually have the right switch box/outlet situation for two installations.
Mini FAQ
FAQs
Does it work when the internet is down? Yes—local control via Bluetooth is described for internet outages.
Which voice assistants are supported? The description mentions Alexa, Apple Home, Google Home, and SmartThings, with Matter supporting direct connection (and SmartThings requiring a compatible speaker).
Do I need extra devices for motion or door automations? The examples that use doors open or motion mention a SwitchBot Sensor requirement, so you’ll likely need that kind of sensor for those scenes.
What appliances does it target? It’s described for lights, fans, heating, and air conditioning, using the existing switch control path.
Is it safe to use with existing switch boxes? It’s stated to have a V0 flameproof casing and over-temperature protection that cuts power during emergencies, plus it restores to its previous state after an outage.
