SaleAqua Fill – Next-Gen Intelligent Water Controller
Aqua Fill by Tronhut is a smart water tank controller that automatically fills your tank when water levels drop, stops filling once the tank is full, prevents overflow, and protects pumps from dry run. It works reliably even without internet and without using the mobile app.
The device can be used completely offline with no subscription required. For users who want to monitor status and control the system remotely, it includes a free 6-month subscription to the Tronhut mobile app. After that, the app service is available at an extremely affordable cost of just ₹30 per month (around ₹1 per day)—entirely optional.

Product information
Product details


Aqua Fill is a next-generation intelligent water controller designed to automate overhead water tank filling with zero manual effort. The device continuously monitors tank water levels using dedicated sensors and automatically starts filling when the water level becomes low.
Once the tank reaches the full level, Aqua Fill instantly stops the pump to prevent overflow and water wastage. The system also includes dry-run protection, ensuring the pump is switched off if water flow is not detected, helping extend pump life.
When connected to Wi-Fi, Aqua Fill sends real-time notifications to the Tronhut mobile app and can communicate with other Tronhut devices such as eRoot and another Aqua Fill for coordinated automation. Even during internet outages, Aqua Fill continues to operate independently in offline mode.
