The HKO integration retrieves weather data from the [Hong Kong Observatory](https://www.hko.gov.hk/tc/index.html) [Open Data API](https://www.hko.gov.hk/en/abouthko/opendata_intro.htm) for meteorological data in HKSAR.

There is currently support for the following platforms within Home Assistant:

- [Weather](#weather-platform)

It displays the weather of your selected location and the 5-day weather forecast for Hong Kong.
