Frequently Asked Questions
How do I install CheckMate?
Simply place the sensor on the base of your LPG cylinder — the magnetic base holds it in place. No drilling, no tools, no gas line interference. Setup takes under 2 minutes.
Is it safe to use on a gas cylinder?
Yes. CheckMate is a non-invasive external sensor — it never connects to the gas valve or line. It uses ultrasonic technology to read the level through the cylinder wall.
Does it need Wi-Fi?
No Wi-Fi required. CheckMate connects to your smartphone via Bluetooth (up to 10 m range). The app works on iOS 13+ and Android 8.0+.
How long does the battery last?
Up to 12 months.
What happens when gas is running low?
The Tuya app sends you a push notification when your cylinder reaches a low level threshold, so you can arrange a refill before you run out.
Will it work on my cylinder?
CheckMate fits 3 kg to 50 kg cylinders from Elgas, Supagas, Origin Energy, Kleenheat, Tasco, and most standard Australian LPG suppliers.
