The JustNimbus integration queries the JustNimbus API used by the JustNimbus web dashboard. This integration allows you to collect and save data to get a historical overview of your water bag usage.


To configure and use this integration, you need to have a JustNimbus water bag (Dutch), and you need to be subscribed for the web dashboard functionality. For this configuration, you need the client ID and ZIP code from the URL. For example: https://dashboard.justnimbus.com/user/view.php?system=<client_id>&zip=<zip_code>. For more help see JustNimbus’ help page.


To add the JustNimbus integration to your Home Assistant instance, use this My button:
