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.

Why Trio

The hub supports up to 6 tanks on Pro. Start with 3 and add more later via the Extra Tank Sensor. Same hub, same open firmware, and the same Home Assistant integration as Solo.

Uses an FCC- and CE-certified LoRa module (Reyax RYLR998)

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.

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.
