Tomorrow.io


The Tomorrow.io integration allows you to obtain weather, air quality, pollen, and fire information from the Tomorrow.io API.

Obtain an API key

You can obtain a free API key by signing up with Tomorrow.io.

The integration will automatically set the refresh interval based on the number of Tomorrow.io integrations that are using the same API key for a given Home Assistant instance. The integration currently assumes you are using a free account so the max requests per day is 100 (the refresh interval is calculated such that you should only use up around 90% of the quota).
