UPDATE: I reached out to developer about issue, they fixed the bug and pushed out a revision. App works great again, thank you for fixing. 5/13/2024 App did work great until a recent update on May 2, 2024. Now all I have for my $50 is a blank white sceeen. Pull back the updated so I can use again......

This is not a free app.

The app is good! But Not sure why it's not offered for free.. Systems requiring this app are all obsolete and old! I have once paid for one and then the developer decided to make it subscription based out of the blue.. I changed almost everything that was running on HAI since then except the swimming pool and the irrigation system.. Frustrating..

Too much for the subscription. Especially after cheating many pro users in the past.
