Know what is left in your gas bottle and water tank, without guessing, tapping or climbing a ladder.

The problem we solve
Across Australia and New Zealand, homes, farms and lifestyle blocks rely on bottled gas for cooking, hot water and the BBQ, and on rainwater for the house, the garden and the stock. Both run out quietly. You find out when the BBQ dies mid-cook, the shower goes cold or the pump starts sucking air.
WiseTank exists so you can see the level before that happens and order a refill, a bottle swap or a water delivery on your own schedule.
What we sell
Gas bottle level sensors: Bluetooth and WiFi models that attach magnetically under a steel gas bottle and show the level in the free TANK IOT app.
Water tank level monitors: a wireless LCD display kit, a LoRa radio model for long distances, a solar-powered model and a WiFi model, using the free Tuya / Smart Life app.
No subscription and no monthly fee on any model.
Our promise to you
Free shipping to Australia and New Zealand, prices in Australian dollars.
30-day returns and a 12-month warranty on every monitor.
Honest listings: if a price is not yet confirmed, the model is listed for enquiry. If a specification is still with the supplier, the page says so. We do not invent numbers.
Not sure which one fits?
Email support@wisetank.co with your tank or bottle size, how far it is from the house and how you want to read the level (phone, display or both). We will tell you which model fits, and which one does not.
