Never worry about your water tank again. A solar sensor on the roof, a quiet hub on the wall, and monitoring that keeps working even when the internet doesn't. Choose LoRa (RYLR998, a pre-certified long-range module) or ESP-NOW Lite (shorter range, ₹500 less).
☀️ Solar-powered, no wiring 📡 Keeps working offline 📶 Up to 5 km line-of-sight ♾️ Lifetime Pro included 🏠 Home Assistant compatible
What you get
- 1× ESP32 hub (OLED, LED ring, and buzzer)
- 1× solar-powered transmitter with JSN-SR04T sensor and BSP mount
- LoRa version: TX includes the RYLR998 module (865 MHz, long range)
- Lite version: TX uses built-in ESP-NOW (no RYLR998, shorter range, more affordable)
- 18650 cell with integrated solar pocket, IP65 PETG enclosure
- Lifetime Pro subscription included
The hub speaks both radios
Every TankSync hub ships with both LoRa and ESP-NOW built in, so it works with either transmitter type. You can even mix LoRa and Lite sensors on a single hub.
About the Lite (ESP-NOW) version
Lite transmitters use the ESP32's built-in ESP-NOW radio and do not include the RYLR998 LoRa module. A little cheaper, with shorter range than LoRa (best for nearby or same-building tanks). Your hub still has LoRa too, so you can add long-range LoRa sensors anytime.
Open at the core
Firmware and hardware files (schematics, BOM, flashing tools) are all public on GitHub. Self-host it, fork it, audit it.
Technical details & certifications
- Uses an FCC- and CE-certified LoRa module (Reyax RYLR998)
- Contains FCC ID: 2AD66-RYLR998
- LoRa radio pre-certified for the 865 to 867 MHz ISM band
Support & docs
1-year limited warranty on hardware. Email support@smartghar.org for help. Full setup and troubleshooting live in the documentation wiki. Home Assistant integration via HACS.
Built by a maker, not a factory line
TankSync is designed, assembled, and bench-tested by hand in small batches before it ships, by the same person who built the firmware and answers your support emails. Open hardware, certified radio, and a real human behind it.
Note: our enclosure is being refreshed, so your unit may look slightly different from the photos. The internal hardware and functionality are unchanged.
Care & Maintenance
To ensure long-term reliability and performance, we recommend installing and maintaining your TankSync devices with care. Periodically cleaning the sensor surface, inspecting mounts and seals, and keeping the solar panel free from dust can help preserve dependable operation for years to come.
