For blocks of flats with a booster set that want to know straight away if something is wrong. The Shelly EM measures the pump's consumption and running time, the Shelly Flood Gen4 sensor with its cable reports water on the floor and the Shelly Pro 1 lets you cut and restore the supply remotely. Alerts to the building manager or the maintenance company from the Shelly app.
What it does
- The Shelly EM, with the 50A clamp on the pump circuit, logs when it starts, how long it runs and how much energy it uses.
- A pump that keeps starting through the night points to a leak in the system or a problem with the expansion vessel; a pump that never starts points to a blockage.
- The Shelly Flood Gen4 sensor, with its sensing lead run along the floor, warns you as soon as there is water in the pump room.
- The Shelly Pro 1 switches the supply to the pump board through a contactor: the maintainer can shut it down and start it again remotely after a trip.
- In the app the building manager sees the run-time and consumption history and gets the notifications.

Before you order
Do you need a hub?
No: the Pro 1 connects by cable or Wi-Fi, the Shelly EM and the Flood Gen4 over Wi-Fi. Everything is managed with the Shelly app. You do need a connection in the pump room: if there is none, it can be brought in with the network cable included or with a repeater.
Does the Pro 1 reset the booster pump?
The Pro 1 does not reset tripped breakers: it removes and restores the supply to the pump's board through a contactor, which helps when the controller locks out and clears on a restart. If a protective device has tripped, someone still has to go on site.
The pump is three-phase: is that all right?
The Shelly EM meters a single-phase circuit: on a three-phase pump a clamp on one phase still shows starts, running times and changes in draw, but not the total consumption. Full metering needs a three-phase meter: get in touch through the contact page.
Do you need an electrician?
Yes. The metering and the switching go in the 230V board in the pump room: the connections must be made by qualified personnel, with the installation isolated, following the manufacturer's diagram. The battery flood sensor goes on with no electrical work.
What happens if there is no internet?
The pump keeps working as it always has, because the kit does not change its controls. The Shelly EM keeps measuring and the modules stay reachable on the local network; notifications and remote control resume once the line is back.
Are batteries included?
The Flood Gen4 sensor runs on AA batteries; check the Amazon listing to see whether they come in the box. The Shelly EM and the Pro 1 are mains powered. The sensor's charge level shows in the app.
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.
