+Support for schedules provided by [hygea.be](https://www.hygea.be/).
+
+## Configuration via configuration.yaml
+
+```yaml
+waste_collection_schedule:
+  sources:
+    - name: hygea_id
+      args:
+        street_id: ID
+```
+
+You id can be found in the url when visiting the [the calendar](https://www.hygea.be/votre-calendrier-de-collecte.html) for your street.
+It may also work by giving it your post code, but this "api" is a mess so only do that if you have no other choice
