“Terrific product! Nice for an old guy not to have to risk the cellar stairs to check my oil! Easy to install.”
“One of the most useful products I’ve purchased. Allows me to check oil level when away from home for extended periods of time and order more as necessary....Don’t need to be home to read the gauge….Great product.”
“Fantastic tool. One time hardware cost. Easy install.”
"Very handy to keep track of oil level so you don't have to sign an auto delivery contract. Also easy enough for anyone to use. LOVE the alexa integration that averages your oil consumption and tells you approximately when you will need to order oil delivery."
"Excellent product. Works perfectly and is very accurate. I was so impressed I bought one for my Father's house."
The Smart Oil Gauge goes in one of the openings on the top of the fuel oil tank. There is typically at least one unused opening with a plug in it (another opening is used for the existing gauge, while another is used for the fill pipe, and another for the vent). Simply unscrew the plug from one of the unused openings and install the Smart Oil Gauge in its place.
No, there are no monthly oil tank monitoring fees.
The Smart Oil Gauge fits into a 2" NPT opening on the top of an oil tank. Please note that the outer diameter of a 2" NPT pipe is not 2 inches, but actually closer to 2-3/8 inches. A 1.5" adapter is available for fuel oil tanks with a smaller opening.
Yes, you can check your home heating oil tank level from anywhere in the world. Your phone does not have to be connected to your home’s router to view what’s in your oil tank.
Walk down to the oil tank and bring your smart phone, tablet, or laptop. Put your phone in 'Airplane Mode' and turn on WiFi only. See if you have internet access by opening up your browser. If the connection is not great, consider purchasing a WiFi range extender.
The Smart Oil Gauge can be used indoors or outdoors. For outdoor installations, the white cap MUST be sealed with Teflon tape or other means to prevent moisture ingress. Expect readings to fluctuate with temperature changes.
The Smart Oil Gauge takes two Saft LS14500 3.6 V lithium AA batteries, which are readily available online. The batteries generally last 1-2 years, depending on WiFi strength, Upload Interval, and other factors. Set your Upload Interval to 24 to maximize battery life.
The upload interval, in hours, dictates how long the device waits before waking up and uploading its latest readings to the cloud. A setting of 1 means the device will wake up and upload every hour; a setting of 24 means the device will only wake up once per day and upload readings. The device will still take a reading once per hour regardless of this setting; it just won’t upload the new readings until the interval passes. For longer battery life, a longer upload interval is recommended.
The sensor currently supports standard vertical or horizontal 138, 220, 240, 275 and 330 gallon above-ground oil tanks, as well as 500 and 550 gallon cylindrical oil tanks. Roth adapter required for 400L, 620L, 1000L, and 1000LH. Not compatible with Roth 1500L. Custom oil tank sizes can be accommodated as well; call 203-456-1499 or email firstname.lastname@example.org to check compatibility. Above ground tanks only.

When an oil tank is filled, the oil level is often too close to the ultrasonic sensor to get a reliable reading, so the Smart Oil Gauge will just say 'Full'. There is also an airspace kept at the top of the oil tank to prevent over-filling. As a result, a 275 gallon tank typically holds around 250 gallons when completely full.
A standard 14” or larger pipe wrench is all that is required to remove the cap from the top of your oil tank and install the Smart Oil Gauge. Be sure to use pipe dope on the threads to create a seal. Do not use Teflon tape on the threads that mate with the oil tank, as this could break down and end up in the oil over time. It is OK to use Teflon tape to seal the white cap in place, as these threads are not exposed to oil.
Open the app and navigate to the My Tanks page. For iOS devices, hit the ‘+’ in the top right; for Android devices, select ‘Sensor Setup’ and follow the instructions to update WiFi. The app will ask you if you are setting up a new gauge, or just updating WiFi; select update WiFi and you are all set!
For iOS devices, click Configure, then '# of Notifications'. From there, click the '+' sign to add a notification/alert. Once you've selected the alert and entered the e-mail address or phone number, press Done. You can continue setting up alerts by pressing the '+' sign. For Android devices, navigate to the 'Smart Oil' page which shows how full your tank is. Click the three dots on the top right, then Configure, then '# of Notifications'. Click the '+' sign to add each additional alert, and remember to hit save in the top right when done. For detailed, step-by-step instructions, go to: www.smartoilgauge.com/alerts

To get started, open the Alexa app on your phone, and go to Skills. Search for Smart Oil Gauge to get the Smart Oil Gauge skill. You’ll need to sign in with your Smart Oil Gauge username and password to link the skill to your account.
To trigger the Smart Oil Gauge skill, always start by saying:
“Alexa, ask Smart Oil Gauge how much oil we have”
Then, you can follow-up with shorter commands, like:
“When will we need oil”
Tip: Consider changing the name of your oil tank from its default name (e.g. MyTank6541234) to something quicker for Alexa to say, like Rental Property. You can change the name of your tank in the Smart Oil Gauge app under settings or configure.
