Take a look at this. It’s essentially a floater in your pool that does tests, sends alerts to you and so on.
There’s an FAQ stating they send raw data that can be viewed and used in Home Automation however I don’t think there is a plugin on the apps.mios site.
Anyone use this or have any experience with it? I have a new Digital Nano controller that I don’t want to spend several hundred to replace that unit although the ePool is about$256.
Take a look.
