Tank Utility

Tank Utility makes LTE-connected propane tank monitors, mobile apps, and a read-only API that surface their data. Its sensors report tank fuel level, temperature, and battery state so homeowners get low-fuel alerts and fuel marketers can route deliveries by real consumption instead of guesswork — Tank Utility says this drops the same gallons in up to 40% fewer deliveries. The Tank Utility API lets an account exchange credentials (HTTP Basic) for a short-lived token, list the monitors on the account, and read each device's latest reading. Tank Utility is owned by Anova.

Tank Utility publishes 2 APIs on the APIs.io network: Authentication API and Devices API. Tagged areas include Propane, Tank Monitoring, IoT, Fuel Delivery, and Telemetry.

Tank Utility’s developer surface includes authentication, CLI, support, engineering blog, and 15 more developer resources.
