For small hotels that want to run the lights and sockets in a room without fitting a hub. Four Shelly 1PM Mini Gen3 modules behind the switches control and meter the lights and sockets, a Shelly BLU contact on the French window reports whether it is open and the H&T Gen3 sensor tracks the room climate. It all runs in the Shelly app, on the hotel Wi-Fi.
What it does
- The four Shelly 1PM Mini Gen3 units switch up to four circuits in the room, for example the main light, the bedside lights, the desk socket and the kettle socket, and meter what each one draws.
- The bedroom switches stay in use: each module is wired to its own existing switch.
- The Shelly BLU Door/Window contact on the French door talks over Bluetooth to the Shelly Gen3 modules, which bridge it to the network: no hub is needed.
- The Shelly H&T Gen3 sensor measures the room's temperature and humidity and sends them to the app over Wi-Fi.
- In the Shelly app you can see which circuits are on, how much they are drawing and whether the French door has been left open, and you can switch everything off at check-out.

Before you order
Do you need a hub?
No. The Shelly modules connect straight to the Wi-Fi and the Gen3 devices also bridge the Shelly BLU Bluetooth sensors. All you need is good Wi-Fi coverage in the room, ideally on a dedicated device network kept separate from the guest one.
Does it work with Alexa or Google Home?
The kit runs from the Shelly app, which also integrates with Alexa and Google Home as the manufacturer describes. In a hotel it usually works best to use the Shelly app from reception and leave guests with ordinary switches.
Do you need an electrician?
Yes. The 1PM Mini modules wire into 230V behind the switches, with live and neutral: the work must be done by qualified personnel, with the installation isolated, following the manufacturer's diagram. The sensors, on the other hand, go on with no tools.
What happens if there is no internet?
The switches carry on controlling lights and sockets. The modules stay reachable on the local network and actions set on the devices can run without the cloud; what you lose is control from off site and notifications, until the line comes back.
Are batteries included?
For the H&T Gen3 sensor, yes: the kit includes four AA lithium cells, because the sensor's own box does not have them. The BLU contact uses a CR2032 button cell; check on the Amazon listing whether it is already in the box.
Can I add more bedrooms?
Yes: each extra room needs its own modules and sensors, all in the same Shelly app, organised by room. Above a certain number of devices it is worth checking the Wi-Fi network's capacity: get in touch through the contact page for the right configuration.
What if a product is out of stock on Amazon?
An item can sell out or change version. Get in touch through the contact page quoting the kit code: we will point you to an alternative that works with the other devices and with the same app, so you keep a combination we have checked and you do not have to go back over anything yourself.
Why buy on Amazon?
Purchase, payment, delivery, returns and warranty are handled by Amazon, as with any other order: delivery times, returns and warranty are shown on Amazon when you buy. The kit is our own work: we picked parts that work together, plus the accessories needed to fit them.
