The Smappee gas & water monitor takes the readings from your gas and water meters and sends this data to the Smappee app on your smartphone or tablet.
You can use the Gas & Water monitor on its own. In that case, you will need a smartphone or tablet that supports Bluetooth 4.0 LE. Please note that in stand-alone use you will not be able to receive real-time leak notifications.
Ideally, the Gas & Water Monitor is used in combination with the Smappee energy monitor, provided that your two monitors are installed within 10 to 20 metres of each other.
