Frequently asked questions
Common questions about connecting Home Assistant and OpenWeatherMap.
Connect your Home Assistant and OpenWeatherMap accounts once, pick an action in one app and an action in the other, then map the fields so data flows automatically between them. [3]
Example: use Home Assistant's "Call Service" action to perform OpenWeatherMap's "Create Station Measurement" action. Home Assistant has 21 actions (including Call Service, Delete Entity, and Fire Event); OpenWeatherMap has 33 actions (including Create Station Measurement, Create Weather Station, and Delete Weather Station). Add filters and transforms between steps when you need them. [1]
Yes — pick an action in either app, then an action in the other, and map the fields between them. [2]
No. Home Assistant-to-OpenWeatherMap automations are built visually on the canvas. You can optionally add custom JavaScript with Functions when you need advanced logic. [4]
Yes. Trigger-based automations start the moment Home Assistant (or OpenWeatherMap) fires a new event — webhook-backed apps run within seconds, and polling-only apps re-check on a schedule you control. [7]
A first automation typically takes 5–10 minutes: connect each app's credential once, drop a trigger + action onto the canvas, map the fields, and turn the workflow on.
You can build your Home Assistant + OpenWeatherMap automation on a 3-day trial with every feature unlocked. Cancel anytime. For your protection, a small deposit is charged to your card when your trial starts. It counts toward your first payment and is non-refundable. [8]
