First, I love this product, being blind it gives me a way to keep track of the oil level of the tank. Second, it also keeps track of the battery level so when the battery level is low, you know it's time to replace the batteries.One thing I wish they would update on the app is the login, would be nice to be able to just use facial recognition, or touch ID to get into the app quickly instead of going into passwords, verifying and then tapping on the proper password for the app login would be nice if we could get that everything in place just needs to be done.Otherwise, thank you for this product. Makes my life a whole lot simpler and a whole lot more stress-free.

So I was so excited to get this. But after a couple days of use there some major drawbacks. The device itself has not refreshed once without me having to tap the button for half a second located on the sensor itself. I have waited a full 24 hours with no refresh. The refresh button in the app is more of a placebo. It doesn’t refresh the information or seem to send a signal to the unit asking it to run the sensor. So you only get the update your sensor has refreshed at the interval set. As for the graphs and usage there’s no ability to zoom in nor does it have a summary of total usage. You have to tap your finger in one area and hope that’s where you want the line to be for that part of the usage. This gives you in very small print your usage numerical value. There is also no ability to delete the device and add it again in case you are having trouble and troubleshooting. In configuration You can change the intervals of how often it takes a reading, but it doesn’t seem to have any effect. I have not gotten a single refresh signal from the device after 3 days of use. I really like this concept and design and am hoping for improvements. Hopefully this review acts as a a way to make future updates.

While I agree with other reviewers who want more flexibility in display graph info, that’s a first-world problem. And it doesn’t detract from the fundamental fact that this is one helluva good idea. I wish there were more connected sensors like this available. I’d instrument everything in my home!Two cautions: first DO NOT put this device on your “real” WiFi network. Get two old routers and connect them with your current router in a “Y” configuration. Then add this to your designated IOT router. Who knows the vulnerabilities that might be in the (unidentified) WIFi chip the developer used. There’s no doc on the site and it’s unlikely that firmware will ever be updated on the device. I don’t want my oil gauge to be a back door into my network. Second, the developer uses WordPress for the site and user management. This is insecure. Be sure to associate the gauge with a dedicated email address.

My mom became an expert at guesstimating when we needed oil. When she passed away, I ran out 2x and had to have to boiler bled which costs more money. I found this Smart Gauge and that hasn’t happened since. I also haven’t been brand loyal to one company. I love being able to choose my oil company based on the best price available. My usual company’s price is usually $40-50 higher than the lowest price. I have 2 improvements for the update. The option to share gauge info or have the option of more than one email on an account. Also, the option to save history of purchases and successful deliveries within the app. I would like to the ability to look back at my history.
