Waterco Electrochlor Mineral Chlorinator Custom Integration

I have created a custom integration for the Waterco Electrochlor Mineral Chlorinator.

I’d been manually pulling data from my Electrochlor for years (and hoping someone else would build an integration!), but eventually decided to just do it myself. It’s my first custom integration, and I’m really happy with how well it works!

For the time being, you’ll need to install the integration manually, as I’m waiting for my pull request to add images to Home Assistant’s branding repository to be approved. Once those images are merged, the integration will become available through HACS.

I’m not sure how long the branding PR will take to be approved, but in the meantime, you can install it manually and it should work fine.

You can get the integration on Github.

I hope someone finds this useful.

The custom integration is now available in HACS.

I have created better icons and logos both light and dark variants. Once the pull request is merged the integration will be complete.

If you have a different model Waterco chlorinator or even a heat pump, raise and issue and I can get any of the missing sensors or switch’s added.

This looks great. Do you know what versions for the Waterco Chlorinator can connect to Wifi? I can’t find any details on how to do that.

What model do you have.

If it is a model that has WiFi it will have a sticker on the side of the unit like the one below.

To connect your phone to the chlorinator hotspot and set the unit to connect to your wifi.

Thanks. I don’t have one yet, I am looking at getting one and want to make sure I get the right model as I can’t see any details about them being able to connect over Wifi

I have the below unit and it has reference to their app in the brochure. If you are looking a another model, ask the shop that you are purchasing from.
