Smart Oil Gauge - Wi-Fi Heating Oil Tank Gauge with Smart Monitoring - Fuel Tank Gauge Compatible with Alexa - Designed for 275/330/500/550 Gallon Tanks (Vertical/Horizontal)

I did struggle with this sensor on my mesh network. I was able to get it connected but after a reading or two, it wouldn't get me another one for days when I had it set to read every 4 hours. I figured out a solution, at least on my network, to this problem. When monitoring the traffic, I noticed that the sensor attempts to connect to get a reading briefly (a min or so). A short enough time where I couldn't assign it to a specific node for my mesh network before it went offline. When I looked at my mesh network, I saw that all nodes were pointed to connect to my main router first causing the network connection of the node the sensor was connected to to be "good" and not "great." Once I forced my nodes to all connect to the closest node to my router, I was able to get a "great" connection and now the sensor has checked in within that 4hr time whenever I go into the app to get a reading. I believe the route cause is that the sensor doesn't stay connected long enough to the Internet so before it would actually connect, it would go offline.My only other qualm with the sensor is the app, there is no way for me to remove the sensor from the app myself. You can only reconnect the sensor by following the setup instructions again so when/if the time comes to replace the sensor, you have to contact customer support to request them to do it. Not ideal and the process took me almost two weeks before they actually did it for me (a lot of back and forth through emails).Other than that, I do really like this sensor and app and will make it a lot easier for me to stay on top of my oil levels so I can rest easily knowing I will not run out of oil and contact my oil company for a refill.

works great

bought this DUO smart gauge sept 24 , (2-330 tanks in basement) it connected to wifi well and kept the connection ,it worked well all winter but when oil level got down to 4.5 inches it showed oscillations in usage.i stuck the tank and it showed 4.5 inches which according to a table is 20 gal/tank so i had 40 gallons.the smart gauge said i have 126.8 gallonsi called for oil and filled to the whistle it took 560 gallons, so 560 + 40 =600so smart gauge is off by 86 gallonsi called smart gauge support, hunter said there might be sludge in the bottom of the tank that throws off the reading.i could not get a different unit to try. i was willing to help them figure out why the unit was reading incorrectly but they don't care since they already got your money.so if your ok with being off by 86 gallons, buy one.

I purchased this. I did find set up took a while so I want to give my advise. First, I set this up on a wifi extender with only the 2.4ghz channel turned on. I have a mesh network that I was struggling with set up on and it was much easier to set up on an old extender I had laying around. I used a linksys extender.I also recommend using option 2 in the guide for setting up wifi. Be sure to enter your email so you can go to the email for set up. I set up the app first so assumed I didn't need to enter my email. I was wrong, the email you get sent allows you to pair the sensor with your account. Be sure to configure the correct tank.I also had to remove the batteries and reinstall them to get it to turn on. If your don't see a flashing light, try that.I got the single sensor unit. It only reads up to 235 gallons on my vertical tank. I would recommend spending the extra 10 bucks for the duo. That's what i would do if I were to purchase it again.All in all it has been working great and would recommend to anyone heating with fuel oil. The setup is a little complicated but not impossible. Would buy again.

Edits:12/11/24 - Years in and it's still going great. The app sends you notifications to alert you if it hasn't received a transmitted reading from the gauge after a few days so you can go and troubleshoot. Usually turning the gauge off and on again per its power switch under its cap fixes most things. The gauge doesn't seem to like the SON(Self-Organizing-Network) setting on my router, and would have awful connection issues so I turned the router setting off. I believe the gauge works best on a 2.4ghz wifi network.6/2/22 - Soon after writing this review, I noticed that the app DID add push notifications a couple months ago. They happened to be off by default in my phone's settings.7/25/22 - After 1 year and 6 months of once per 24 hours data reporting, battery finally started to report "Fair" for a couple weeks and then advanced to the lowest level of "Poor" and sent a low battery notification via push notifications and email.Original Review:I got tired of watching my dad constantly go outside to check the mechanical oil gauge on the tank, so I thought there had to be some sort of remote monitoring for that in this day-and-age. I stumbled upon this and after some research, said "Sure, sounds good!".Installation:I ordered some pipe-dope (pipe glue/sealant) along with it and installed it on a cold winter day (Northeast US) in January 2021. My outdoor 275gal vertical oil tank had a cap on an extra unused port so I didn't have to remove any of the other devices on the oil tank. (fill spout, fill whistle, and manual oil gauge.) With a pipe wrench and a 1.5 foot long piece of discarded metal pipe as a handle extension, I was able to get the rusted-stuck cap loose and removed.I took my pipe dope and painted it all around the outside of the metal bottom threads on the Smart Oil Gauge (avoiding the sensor within the black colored area on the end) and screwed it into the hole. It doesn't screw all the way in; it leaves about 5 threads exposed once I tightened it as comfortably tight as it would go.Setting it up with the wifi network went smoothly and I set it to report its readings once every 24 hours, which is the maximum time between reports. Its "brain" is located underneath the white plastic screw-on cap on top. There is a small circuit board with a couple of wires connected, and a compartment with a power switch for your two lithium AA batteries and some styrofoam to keep stuff in place. Somewhere in there is the "configuration" button for wifi syncing and such. You are instructed to wrap teflon tape around the metal threads where the plastic cap screws on to seal the compartment from moisture penetration.Battery:The less you make it report, the longer your battery lasts. Trust me you don't need a report more frequently than 24 hour intervals. I even forget to look at it for days at a time. The app's battery report has a total of four possible readings: Excellent, Good, Fair, and Poor.(See 7/25/22 Edit At Top)At the time of writing this review, one year and four months after installing it, I still haven't had to change the battery. The battery started at "Excellent" and now reports "Good" which is one step lower. There was a time where it reported "Fair" for a short while, but then it went back to "Good" somehow.Cons:I ended up purchasing replacement batteries when I had a one-time connection problem in which we had a lengthy power outage and the Smart Oil Gauge struggled to get back online afterwards and didn't report to the app for about a week(which the app notified me), so I thought it was suddenly dead. While troubleshooting, I thought perhaps it had lost the network and I would have to reset its connection, but when I followed the instructions to reset the network connection, everything kept failing and timing out. I emailed support about the issue during the troubleshooting process and they gave me the same network-resetting instructions from the manual. I replied to tell them that resetting the network failed and how I even rebooted my router, and they emailed back with something along the lines of "Thank you for letting us know that we helped fix your problem!". It turns out going outside and shutting it off for a minute and then turning it back on by its power switch, knocked it out of its tantrum and it has been working normal ever since and automatically reconnected back to the network.The readings can come up as a couple of gallons more or less than actual when the outdoor temperatures are in the extremes. (Hot Summer makes gallons read higher, Cold Winter makes gallons read lower than actual.) This can make it seem like you are using more, less, or even negative amounts of oil on some days. It's a minor annoyance but not really a problem because it's not like we push the tank gallon by gallon. We just refill when we get around 1/2 tank.You cannot choose what time the gauge reports to the app. You can choose the approximate interval, but not the time. That means that sometimes my gauge reports before or after the 24 hour mark, so that ends up having the time of the update drift all over with no way to reset it to a specific time. Some weeks my 24-hour reading would come in 1am, other weeks 3:15pm etc. It drifts.Unfortunately this drifting causes a strange effect in the app, which once you hit 12am and begin a new day, the app no longer allows you to view the previous day in detail, as there is no scrolling through day-to-day readings. There are graphs of level and usage rates for "Today", "This week", "This Month", and "This Year". That means that if your gauge has drifted to updating at 8pm, then you only have 4 hours to view today's readings in detail before the daily slate gets wiped clean and you can only view the day as part of time-stamped dots making up the graph in "This week". Anything beyond a year is lost as there is no history collection beyond that.(See 6/2/22 Edit At Top)The app's notifications are done through odd combinations of email and text messaging. Certain notifications can only be sent through entering an email into the box in the notifications page, and some can only be received through entering a phone number to text. For some reason the app doesn't do regular push notifications to tell you when your tank is at 1/2, 1/4 etc.My tank is 275gallons and is set to that same amount within the app. The sensor reads "Full" at 230 gallons--presumably because the sensor needs space above the oil to read properly, or because of how far the sensor drops down into the tank when screwed in. This means that if you end up filling beyond your "Full" reading, it's going to seem like you aren't losing any oil for however long it takes you to finally drop below your "Full" level." This level is likely to be different for those with other tank sizes or configurations.You can use the FuelSnap oil marketplace to order oil from your choice of local participating oil vendors at the click of a button with the addition of a payment source. FuelSnap is not a subscription service, but built into the app.All in all, I am quite happy with it though it can use some app improvements.
