+## Automation
+
+Due to the many weather integrations available and their relevance to your situation, there is realistically no way to provide a run time 'auto-adjustment' feature. Therefore, no attempt has been made to include a solution and this also makes the integration more independant. Run time adjustment is achieved by way of services which can be called from within Home Assistant. This does mean some knowledge of creating automations is required.
+
+On a personal note, I use the national weather service for my forecast information but find their observation data not relevant due to the extreme regional variations in my situation. There are many micro climates (mountains) and a few kilometers in any direction makes a lot of difference, down pour to a few drops. To this end I have a Personal Weather Station (PWS) that feeds Weather Underground where I use the [WUnderground](https://www.home-assistant.io/integrations/wunderground) integration to retrieve the data.
+
+You will find my adjustment automation [here](./examples/irrigation_unlimited.yaml) which feeds off the temperature and rainfall observation data. Some ideas were gleaned from [kloggy's](https://github.com/kloggy/HA-Irrigation-Version2) work.
