a couple years ago I purchased the Mopeka tank check system. I had the one with the inside monitor. It has worked fine until I replaced the batteries. Now tank 1 shows full and tank 2 shows empty and both tanks have been recently filled. When the Gateway became available I ordered one. Now the phone app shows both tanks empty.....I have done a couple of things that the trouble shooting hints said to do to no avail.....My friend bought his the same time I did mine and got so frustrated with his that he threw his in the trash. I do not want to go to that extreme.I have emailed the company a couple of times but their suggestions do not help either....

I also added the Mopeka tank halos on mine. Like them as well.

Mine do that occasionally also. It’s all about their position on the tank bottom, also the rubber can get bunched up or dislodged at the sensor. One of my sensors wires broke off at the solder joint, I repaired it. Just try to reposition it on the flat part of the tank bottom, make sure it’s clean and no rust or anything.

I removed my sensors, took the system off, and an done trying to figure mine out..They worked the first year, sketchy the 2nd year, and mostly not at all the 3rd..

removed it , the phone app worked ok but the rubber feet they give you got compressed and crushed one of the sensors, I had the phone app which worked much better than the remote monitor, nice idea but need some refinement to be a quality product. Have one sensor left and one crushed one . purchased the levelcheck truma level checker , pricy but has worked great and is accurate, and is not subject to the jarring and bouncing over the road when traveling

They upgraded to metal feet. Call them and they will send you some for free.

  The Halo's are awesome just apply a double sided tape or a adhesive in about 4 spots on tank rim before putting on Halo so it keeps it secure and in place. They put enough lift on tanks to keep from smashing the sensors and they protect the tank ring from getting scratched or gauged n rusty. They are perfect. I took and cut a piece of corrugated plastic into a circle the exact size of the inner Halo ring and I push that to make a cover over the tank sensor to protect it from weather and from it falling off or being shifted around accidentally when my tanks are being filled. I've been doing this for about 4 years now and still working perfectly.

I haven't had a problem with mine. Any time I refill a tank, I use this procedure.

- clean bottom of tank with paper towel
- clean sensor
- apply pea sized amount of dielectric grease to sensor
- stick on tank

It will take a little while to read the new tank as full. I usually verify it later that day or the next day.

I only use the phone app to check mine. Really nice to be able to get tank levels without touching the tanks.

I do the same thing on both of our tanks and have never had any issues with the app or indoor monitor. And I have also found that they are very accurate by comparing the measured level to the amount it takes to top the tanks back off.

x2 on this. almost 2 years using on my 2 tanks. based on refill amounts the sensors seems to accurate.

OH Boy my monitor says both tanks full, one of the sensors is not even on the tank and is is in the house. My phone app says both tanks empty I think my whole system is toast.....

Had similar problem. Called the CO. and they suggested the "dielectric grease" fix. It worked great.

I called the company and they were puzzled as to why one of my sensors tells the monitor that the tank is full but tells my phone app that it is EMPTY, but shows battery is good......they are sending this problem to the design engineer to see if he can figure it out.....

mine has done something similar on more than one occasion where phone and monitor don't match one indicates a fill level, the other empty.

Anywhere from 10-30 minutes later they will finally match

let us know what they find.

Interesting, at least they are trying to chase the problem down. Keep us posted once you receive some feedback from them. Never know when one of us may run into the same problem.
