Ecowater Hydrolink Custom integration for Home Assistant

Hi everyone

First release of my custom integration for Ecowater water softeners that use the Hydrolink platform (EU). This integration allows you to monitor your water softener directly from Home Assistant, with detailed sensors and alerts.

Currently, there are 30 sensors available, and many more are possible. Although I think the most important ones have been adopted.

Hi

Meanwhile, the integration has been expanded to allow users to select the US or EU platform during installation.

Both the EU and US platforms have been tested.

To do:

  • Enable unit selection (liters/gallons)
  • Review potential translation errors
  • Update interval → live data

Hi, thanks for sharing! Good timing, I just got my device. Just installed it and it works like a charm :slight_smile:

I tried configuring the integration and it logged in just fine but it fails when it initializes. Error message is "Failed setup, will retry: Error connecting to Ecowater API: Update failed: Update failed: “NoneType” object has no attribute.

The logs says this:
This error originated from a custom integration.

Now I do have 2 devices set up on the account and I saw that this hasn’t been tested with more than one device. I have a softener and and iron filter. Could that be the issue?

Actually that was it. I removed the Iron filter from my profile and it is now showing up with 36 entities.

Any idea how to add the 2nd device?

BTW Thank you for an awesome integration! :slight_smile:
