TankSync Additional RX Hub

A spare TankSync hub for warranty replacement, a second site, or peace-of-mind backup. Plug it in, re-pair your existing transmitters in about two minutes, and your tanks are back online.

Perfect for

• Warranty replacement if your original hub fails
• A second site (city home, farmhouse, parents' place)
• A spare kept on the shelf for backup

What you get

• 1× ESP32 hub with SH1106 1.3" OLED, WS2812 LED ring, and buzzer (identical to the Solo/Trio kit hub)
• 1× RYLR998 LoRa module, pre-installed
• USB-C cable and Indian 2-pin wall adapter
• Quick-start card with re-pairing QR and hub MAC address

Important

Solar transmitter not included. This is the indoor hub only. Pair it with your existing transmitters, or order Extra Tank Sensors separately if you're deploying to a new location.

Re-pairing

Re-pair your existing transmitters in under two minutes via the hub's local web UI. The new hub inherits your account's Pro entitlement, so it becomes a covered site automatically.
