TankSync Solo — 1 Hub + 1 Tank Sensor

Never worry about your water tank again. A solar sensor on the roof, a quiet hub on the wall, monitoring that keeps working even when the internet doesn’t. Choose LoRa (RYLR998 is a pre-certified long range module)  or ESP-NOW Lite (shorter range, ₹500 less).

What you get

• 1× ESP32 hub (OLED + LED ring + buzzer)
• 1× solar-powered transmitter with JSN-SR04T sensor + 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 + 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 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.
