Mopeka Pro Check Sensor - Wireless Propane Tank Magnetic Sensor Level Indicator - Propane Gas Tank Pressure Gauge Electronic for BBQ Grill - Remote Ready Propane, Butane and Fuel Level Gauge with App

Ok, so no one should ever need this for a propane tank on your grill or generator. You use it, it runs out, you replace. Skip that thought for a moment. It’s super nice knowing exactly how much propane is left on a tank, and being able to plan ahead. The Bluetooth connection is solid, the readings are consistent, and there were no “gotchas”. I’m glad I got it, and I think it’s a great device. Do I absolutely need it? YES! 🤣

EDIT - I previously rated this 3/5 stars due to only 1 of 2 units working properly. However, the seller quickly contacted me and resolved the issue with a refund. Because of the quick response from the seller, I'm updating to 5/5 stars for the superb handling. The other unit I have works fine.Also, many comments on here say the battery is not replaceable, that is not true. There's 4 small indentions on the faceplate of the main body of the sensor where you can insert a small flat object (like a flat-head screwdriver) and pop the face cover off which will expose the internal components and the battery. I just wanted to add that, as there are quite a few comments claiming the battery isn't replaceable.Below is my original review of the Mopeka sensor. I ordered 2 units and despite having trouble getting 1 of the 2 units to work as well as my other, I'd still recommend buying if you're looking at these as I may have just gotten unlucky. But because the seller contacted me so fast and resolved the issue, they get an "A+" in my book.-----------------I purchased 2 of these for my 2 100lb vertical tanks.Set up was very easy and it linked to my phone via Bluetooth immediately. I followed the instructions for the first one and immediately got an accurate reading and a max star quality reading (1 is low quality and 3 is max quality sensor reading).I then installed the 2nd one on the bottom of the 2nd tank and no matter what I did, it kept giving me an error message on my phone saying the sensor was not properly placed for an accurate reading. I tried cleaning the bottom of the tank, cleaning the sensor, re-synchronizing the device, adding more gel to the sensor, recalibrated the level system, and nothing worked. I decided to just roll with it and see if it would work.It sort of works, but not nearly as good as the first one. After two weeks (and trying all the above AGAIN) , it still says the sensor is incorrectly positioned. Furthermore, it has trouble updating as frequently as my first sensor as shown in the screenshot. It struggles to update itself, which is frustrating when I'm using that specific tank. Sometimes it updates, sometimes it doesn't. See in the screenshot where my first good sensor updated immediately and my 2nd sensor hasn't updated for 22 hours. These tanks are right next to each other, so it's not a range issue.I don't know if this is a Bluetooth limitation or I got a defective unit, but considering the sensor issues I'm having with my second one, I'm leaning towards a defective unit.If I didn't have these issues, I'd no doubt rate 5/5 stars as my first one I've had zero issues with. It updates almost immediately when I open the app, says I have a good sensor reading, and is giving me an accurate reading. I can see the fuel deplete slowly in real-time while I'm using it.The second sensor, does none of those things.Lastly, my only other comment is that the low fuel level warning option in the app is a bit pointless as you basically have to have the app open to get a current reading of your tanks The app will not update the tank fuel levels if the app is closed or if it's been in the background for an extended period of time. I was looking forward to using this alarm feature as these tanks heat our house, but was very disappointed when I realized this limitation of the app having to be open on your phone. As it makes it a bit pointless when my tank is low, but I haven't received a notification on my phone. But then when I open the app and it updates and it recognizes my tank is low, THEN I get a phone notification that the tank is low.So I just turned this feature off.Otherwise the app itself is great! No bloatware, very simple design, easy to use, options to select various sizes tanks, able to rename and even put tanks in groups, etc.

Easy setup. Just works. Downloaded the app, pushed the sync button—paired. Did that 4 times for 4 sensors. No issues over the last six months of use. Want personalization? You can setup each tank sensor with names, how often it updates, manually specify tank size, and more.I also purchased the Mopeka Gauge display and Bluetooth/WiFi Bridge. I don’t have to use my phone with the Gauge but it’s a simple push/button check. Personally, I find myself using my phone mostly, which is where the Bridge has worked flawlessly for checking remotely (not at home within Bluetooth range). Full-Time RVers: get this system.I had a tank on the ground during freezing/thawing weather. Water got into a sensor and broke it. I ordered one of the newer sensors that does more than just propane. It took me 5 seconds to pair the new sensor and 30 more seconds to name, specify tank size, read timers, and more.Note: I did find that while remotely checking, I would have to, from the Account tab, tap the Location symbol to change it to a Cloud symbol, then immediately change them back, to get a readout. Took all of a few seconds.Note2: Create an account after downloading the app to use the remote capability. Local Bluetooth only use does not require an account.

These work great. However getting these set up seemed much more difficult that it should have been.First, the sync buttons on the sensors are "mushy" and you have to push hard on them to activate the switch. Not wanting to damage the switches, or circuit boards inside, I couldn't get them to sync. Assuming the batteries may be the issue, it took them apart and discovered your really need to press hard on the sync button. Push hard enough and you will feel the switch "click". They then paired immediately.The app has issues for me as well. Going to the "help" page leads you to the 404 no page to be found. Really?Thinking setting up an account and registering might make thing easier and function as expected, led me to wait 15 minutes for the email needed to verify my account.Next, I ordered the halos for the tank bottoms but found they increased the outside diameter just enough my tanks would not fit into my trays. No worries, the sensors came with 3 little aluminum clips for the bottom rim to raise the tanks enough to allow clearance for the sensors. However, when I tried to tap them on the rim with a hammer, one split in half. Going to plan B, I ended up cutting the rubber halo into sections which allowed the tank to fit into the tray and prevent damage to the sensors by giving enough clearance.Then there was the centering of the sensor on the tank. I forgot to use the dielectric grease on the first one and it centered beautifully. Cool. I then removed it, greased it which then resulted in the sensor wandering around and not staying put. A very thin layer of grease, if any at all, will suffice.They are installed, they work well and I have a spare set of batteries in the trailer when its time to replace them!

Have this installed on my 120 gallon vertical tank. Battery has lasted months already and this keeps accurate readings on my propane levels. Also good to check on the propane trucks report. Glad I purchased this. Will buy this brand again if I ever have the need.
