ecowater_softener is a custom component for Home Assistant. The integration allows you to pull data from your Ecowater water softener.
It will create one sensor with multiple attributes.
Copy the custom_components/ecowater_softener folder into the config folder.
To add an Ecowater water softener, go to Configuration > Integrations in the UI. Then click the + button and from the list of integrations select Ecowater Softener. You should then see a dialog like the one below.
You then need to enter the information you use to login on https://wifi.ecowater.com/Site/Login. (Serial Number = DSN)
Then you will need to select the date format that your Ecowater device uses. You can check this under the Out of Salt Date and Last Recharge at https://wifi.ecowater.com/Site/Login.
This will then create an entity sensor.ecowater_serialnumberhere. This sensor will update every 30 minutes.
