Meet the Refuel: a small tool that lets you monitor your propane tank from your smartphone. When your grill is in range of a WiFi network, Refuel allows you to monitor your propane supply from anywhere and even receive alerts when you are running low. You can also tap Refuel’s sensor to display the gas level.
The device is made of reinforced plastic, heat resistant cable, rubber, and magnets. The device connects to the Wink app on your mobile device to keep you informed. You can get it on Quirky.
