eSzambo

Its wireless sensor measures the tank’s fill level and sends information through a base station to the eSzambo mobile app. Users can check the level remotely and receive reminders to arrange emptying, reducing the need for manual checks and helping prevent unexpected overflows. The sensor is designed to suit almost any tank, with some concrete ring-only tanks potentially requiring confirmation of compatibility. Installation requires no drilling or fastening; the system includes instructions and mounting accessories.

The app’s core features are available under a free licence. Users can add the paid eSzambelan subscription, which uses monitoring data to estimate collection dates and can arrange waste removal with a service provider. After collection, users can also receive information about the volume removed to help track costs. eSzambo is intended to make septic-tank management more convenient and support more efficient collection planning.
