HomeTank
Water, on autopilot.
A wireless LoRa tank monitor and pump controller. Through four floors of concrete. No Wi-Fi. No wiring. No thinking about it.
HomeTank Features
Water Management Made Smarter
1. Multi-Tank & Capacity Setup
Easily select your water tank capacity (from 500L up to 10,000L+) right from the mobile interface. Tailor monitoring thresholds specifically to your home's daily usage patterns.
2. Smart Schedule Automation
Never worry about overflows or dry runs again. Set automated ON/OFF pump schedules based on municipal water supply timings or custom intervals that fit your lifestyle.
3. Live Level & Flow Monitoring
Get real-time updates on exact water volume, battery health of the solar sensor, and instant flow rate alerts right on your dashboard wherever you are.
4. Long-Range LoRa Wireless Unit
Our industrial-grade wireless transmitter communicates up to 1+ km through concrete walls without requiring Wi-Fi on your roof, completely powered by clean solar energy.
5. Non-Contact Ultrasonic Precision
Zero moving parts in the water. Advanced ultrasonic sound waves measure water depth down to the millimeter with exceptional reliability and zero maintenance.
6. System Architecture Overview
Comprehensive breakdown of how our Heltec ESP32-S3 LoRa telemetry communicates directly between the top roof lid unit and the ground motor relay.
7. Rugged Solar Lid Verification
Self-sustaining top lid unit inspected and verified in real-world outdoor conditions. IP65 weatherproofing designed for extreme sun, heat, and heavy monsoon rains.
8. Concrete & Syntax Tank Mounting
Easily installs onto standard concrete slabs or plastic overhead syntax tanks with secure external bolts—requiring zero drilling into internal water layers.
Real-time Updates & Complete Ecosystem
Explore our full multi-tank architecture, automatic scheduling, pump automation, and LoRa wireless telemetry in one big master view.
Autonomous Smart Tank System.
Set & Forget Automation.
Watch how our wireless top sensor autonomously monitors water levels, automatically triggers your ground pump at 20%, and stops safely at 90% full—requiring zero manual input once running.
Simple, Transparent Packages. Zero Subscriptions.
Every hardware kit includes our pre-flashed Heltec LoRa nodes, IP65 ultrasonic sensor, and high-load ground pump relay controller.

Open source. Build your own.
Two Heltec WiFi LoRa 32 V3 nodes talk over LoRa. The Top Node measures level and temperature in the tank; the Bottom Node runs the pump and serves the companion app over Wi-Fi.
Tanay2920003/HomeTankAdd the board package
In Arduino IDE Preferences, add Heltec's board manager URL, then install “Heltec ESP32 Series Dev-boards”.
Install libraries
RadioLib, Heltec ESP32 Dev-Boards, DHT sensor library and ArduinoJson. Click Install All for dependencies.
Pair the nodes
Set the same UNIT_ID in both sketches. Unit 2 uses 1002, unit 3 uses 1003, up to 65535.
Required libraries
- Top + Bottom
RadioLib
SX1262 LoRa radio
