Meet the Tank Utility Smart Meter: a smart meter for your propane tank. It lets you remotely monitor your tank’s fuel level, monitor prices, and order from your smartphone. The device sends you a notification when your tank is running low on fuel. It can identify leaks too. You can view historical consumption data to figure out how you can save energy.
Tank Utility’s smart meter is easy to use. Just snap the sensor on your tank, load the app, connect to WiFi, and you are ready to go. You can view your data online or through your smartphone. The developers have created an open REST API to allow you to automate your home. The battery life is good for 3 years. You can order yours on Kickstarter.
