For building managers and blocks of flats that want the stair lights on only when they are needed. The Shelly Pro 1 in the communal board controls the stairwell lighting circuit, four Shelly BLU motion sensors on the landings switch it on as people pass, and the existing buttons stay in use. Times and schedules are set in the Shelly app, with no hub.
What it does
- When a resident walks onto a landing, the Shelly BLU Motion sensor picks them up and the Pro 1 switches the stairwell light on.
- The light goes off after the time set from the last movement, instead of staying on for a fixed period.
- The stairwell buttons keep working, wired to the Pro 1 input, for anyone who prefers to switch the light on by hand.
- The BLU sensors also read light level: during the day, with the stairs already bright, switching on can be blocked.
- In the app the building manager sees the state of the circuit and changes times and schedules without calling the engineer.

Before you order
Do you need a hub?
No: the BLU sensors talk over Bluetooth to the Shelly Pro 1, which puts them on the network. You need a Wi-Fi or cable connection at the board, for example a router dedicated to the communal areas.
Does the signal reach every floor?
It depends on the floors, the walls and the distance from the board. Bluetooth has a limited range: with the board on the ground floor, the upper landings may not be reached. Test the signal in the app before you fix the sensors; for the far floors you add a Shelly Bluetooth repeater. Get in touch through the contact page.
Do you need an electrician?
Yes. The Pro 1 goes in the building's board on the 230V stairwell lighting circuit: the connections must be made by qualified personnel, with the installation isolated, following the manufacturer's diagram. The battery sensors go on with no electrical work.
Does it work with Alexa or Google Home?
The devices run from the Shelly app, which also offers integration with Alexa and Google Home as the manufacturer describes. In a block of flats, app access is best given to the managing agent or the maintenance contractor, not to every resident.
What happens if there is no internet?
Communication between the sensors and the Pro 1, and the actions set on the device itself, work locally, so the light still comes on as people pass. The push-buttons always work. Without a line, only remote control and notifications are missing.
Are batteries included?
The BLU Motion sensors run on a coin cell; check on the Amazon listing whether it is already in the box. Each sensor's charge level shows in the app, so the building manager knows when to change it.
Can I add more floors?
Yes: for each floor you add a BLU Motion sensor, paired to the same Pro 1, and a repeater if the signal does not reach. Several stairwells need one module per lighting circuit. Get in touch through the contact page.
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.
