Thanks man! But... now for some reason ultrasonic reading is a bit off. In code i have deviation 10cm and tank height 110cm so every 10cm in real life shoulb be 10% in the reading. But it isn't. If i move an object 10cm the reading drops only 4%. I have input voltage for Z-Uno on 5.02V, so that should not be an issue.

Other than that, the project turned out quite well.
I have put Z-Uno and Vera Edge into one box. The whole idea was to make a device that can measure different temperatures and also pellet bunker fulfillment level and you can access that information through mobile phone plus get notifications when temperatures are too high/low and also when bunker level gets too low. To justify the use of z-wave devices, it leaves open the opportunity to always add more devices like smoke detector or flood sensor etc.

Heres some pictures for you guys.
