Smart Oil Gauge has redefined how we think about heating oil.

No more trips to the basement to check the tank. No more middle-of-the night runouts. Know when you’re low, and order oil on your own terms. Our Smart oil gauge can even notify your supplier when your running low.


The Smart Oil Gauge™ is the first connected home device of its kind that allows you to remotely monitor your home heating oil tank. The Smart Oil Gauge uses an ultrasonic sensor to measure the level of oil in the tank throughout the day, and transmits this information over your home’s Wi-Fi network. Check your tank level from any smartphone, tablet or PC – anywhere in the world. When the tank is low, the device will send text and e-mail alerts indicating that it’s time to order oil. Alerts can be sent to anyone inlcuding your fuel oil supplier for delivery request.


Indoor tanks only ( See option for outdoor tanks )


Also works with Alexa. Just ask Alexa how much oil you have.


  • REMOTE OIL TANK MONITORING: Check your heating oil tank from your smartphone – anytime, anywhere. Don’t worry about running to the basement to check your tank. Check your tank from work, vacation, or wherever you have internet access. Great for rental properties and hard to reach tanks.
  • LOW-LEVEL ALERTS: No more middle-of-the-night runouts. Smart Oil Gauge will send you text and e-mail alerts when it’s time to order oil.
  • ENERGY EFFICIENCY: Track your heating oil usage by the hour. Watch how much oil you burn throughout the day, and adjust the thermostat to conserve fuel. Save money on heating oil by optimizing the thermostat settings.
