TankSync Extra Tank Sensor (TX)

Add another tank to your existing TankSync setup — now in LoRa (long range) or ESP-NOW Lite (shorter range, ₹500 less).

What you get

• 1× solar-powered ESP32-C3 transmitter
• 1× JSN-SR04T ultrasonic sensor + BSP-threaded mount
• 1× 18650 cell + integrated solar panel pocket
• LoRa version: includes the RYLR998 module (865 MHz, long range)
• Lite version: built-in ESP-NOW — no RYLR998, shorter range, more affordable
• Pairs with any existing TankSync hub — the hub speaks both radios
• Inherits your hub’s Pro subscription

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 one hub.

• Uses an FCC- and CE-certified LoRa module (Reyax RYLR998)
• Contains FCC ID: 2AD66-RYLR998
• LoRa radio is pre-certified for 865–867 MHz ISM

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 / same-building tanks). Your hub still has LoRa too, so you can add long-range LoRa sensors anytime.

Compatibility

Requires an existing TankSync hub. Up to 6 tanks per hub on Pro tier. No hub yet? Start with the Solo or Trio kit.

Note: our enclosure is being refreshed, so your unit may look slightly different from the photos. The internal hardware and functionality are unchanged.
