Seems to measure correctly, though accuracy is still unclear. Sensor connection and mounting are easy. Unfortunately, my 20‑year‑old tank isn’t listed, even though it was common in Ireland. The UI should allow editing tank parameters without deleting and re‑adding it. An option to show the oil level in cm is missing, which would help verify readings. A visual tank display would also be great.

Useless info. How can you trust what it says! 66% full 802ltrs left. 4 hours later, 68% full 793 ltrs left and boiler wasn't even used during that period. Spurious guesswork in my opinion. Also, during recent times of high fuel prices and long wait times for delivery I find out my local supplier with whom they share my data was monitoring what I had left & deciding themselves when I got my oil and I have recorded verbal proof of that. Unacceptable. I do not recommend this product or app.

Simple and works, but needs to be more flexible. In particular, need to be able to change the tank calibration later. The initial tank setup is always going to be hit and miss - measuring a bid oddly shaped tank with a tape measure. But once it's running there doesn't seem to be any way to change the tank details. For example, if I get 600 litres delivered, then that's a known volume to link to the before and after measurements. Or if the tanker delivers as much as it can, then that's 100%.
