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 as it should.

No matter what I did I could not connect to wifi and stay connected. I moved my router, restarted my router, turned off and on, etc. My router is not even that far from the tank (which is in the basement). I finally connected, went down to install it and bam…no wifi again. I then moved the router as close as it would go and finally got it to connect. I called my service guy to install after I filled the tank. He said no way does he even recommend this. It’s got lithium ion batteries, which by the way he said have to be replaced constantly, and the device is not even UL certified. He said he’s strongly against installing the device due to the risk involved with this type of batteries on a tank of oil…huge fire hazard and not worth the risk. I told him to go ahead since I already bought the thing but lo and behold, as soon as we go to install it…no freaking wifi AGAIN. We got back on wifi, and put it on. The reading was not even accurate even with trying to troubleshoot. Between connection problems, massive fire risk due to lithium ion batteries on an oil tank…and a device that is not even UL certified..and completely inaccurate, no thanks. I am returning it. There are also too many bad reviews about how inaccurate the readings are with it, and I’m not the only one with the connection issues. I called my service guy again three days later after the reading was still incorrect and had him remove the device. Nice waste of money all around with the cost of the device and the cost of a service call.

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.
