Switches the well pump on and off from your phone even where there is no internet line, thanks to the industrial 4G router. A Shelly Pro 1 switches the pump, directly or through a contactor on more powerful pumps, and a Shelly EM with a clamp measures the current draw to spot dry running and stop the pump.
What it does
- The 4G router with a data SIM creates the Wi-Fi network in the well house and puts the devices online.
- The Shelly Pro 1 switches the pump on and off from the app, by hand or on a watering schedule.
- For more powerful pumps the Pro 1 switches a contactor coil instead of carrying the load directly.
- The Shelly EM with the 50A clamp meters the pump's power and consumption and keeps the history.
- If the pump draws far less than normal, the classic sign of dry running, a rule switches it off and sends a notification.
- In the app you can see at any time whether the pump is running and how much it has used over the day or the month.

Before you order
Do you need a hub?
No. The Shelly modules connect over Wi-Fi to the 4G router included, which takes everything online with a data SIM. Nothing else is needed: the Shelly app on your phone reaches the modules through the router.
Do you need a SIM?
Yes, a data SIM from any network, not included. The traffic for commands and readings from a few modules is small: a basic data plan is usually enough. Check the mobile coverage at the well before installing.
Do you need an electrician?
Yes. The Pro 1 and the EM are wired at 230V in the pump board and, on larger pumps, to a contactor: the work must be done by qualified personnel with the installation isolated, keeping the existing protective devices in place.
How does it detect dry running?
A pump running dry draws less current than normal. The Shelly EM measures power continuously and a rule switches the pump off if the figure stays below a threshold for a set time. It is an extra layer of protection: it does not replace float switches or the pump's own protection devices.
What happens if there is no mobile signal?
The pump stays as it is and app control resumes once the signal returns. That is why it is worth setting a maximum run time and keeping the pump's own protection devices, which do not depend on the connection.
Can I add devices?
Yes: more Shelly units for zone solenoid valves or a second pump, sensors for the tank level, more meters. They all connect to the same router and run in the same app.
Can I switch a three-phase pump?
Yes, through a three-phase contactor driven by the Pro 1; metering the consumption on all three phases then calls for a three-phase meter, such as the Shelly Pro 3EM. Get in touch through the contact page for the right build.
What if a product is out of stock on Amazon?
An item can go out of stock or be replaced by a new version. Get in touch through the contact page: we will point you to an alternative that works with the rest of the kit, so you do not have to check it against the other devices yourself.
Why buy on Amazon?
Purchase, payment, delivery, returns and warranty are handled by Amazon and by the sellers of the individual items. The kit is our own work: we choose the parts, check that they work together and tell you how to fit it. Delivery times, returns and warranty are shown on Amazon when you buy.
