Solutions

Shelly Flood

No unexpected leaks while away

Thanks to its small size, Shelly Flood can fit virtually anywhere. Simply place it where leakage might occur - right under any water or heat pipes, fridges and freezers, washing machines, etc. Shelly Flood will notify you in case of the slightest leakage - letting you react before a puddle forms.

Stop water when not at home

We're all planning time away, but we shouldn't have to leave our homes fully unsupervised. Use Shelly Plus 1 to control your home's water supply and Shelly Flood to monitor for leaks. Together, they can save your home from disastrous water damage! If Shelly Flood detects a leak, it will trigger Shelly Plus 1 to close off the water supply to minimize damage caused by the leaking pipe or appliance.

Equipment damages prevention

Shelly Flood sensor can prevent potential threats, including equipment damage by simply placing the smart sensor close to which your appliances are connected. If Shelly Flood detects any leaks, it will immediately trigger Shelly Plus 1PM to cut off the power supply of the sockets, preventing potential threats.

Efficient floor heating control

Make sure the temperature of your business facility or home is always welcoming – whether it’s a yoga studio, gym changing room, spa center, or your own living room! Shelly Flood can monitor the floor temperature and trigger Shelly Plus 1PM to turn on the heating system when the temperatures drop below desired levels.
