No Way To Remove AC/Heat Units
It has a fatal flaw. You can’t remove air-conditioning or heating units if they aren’t working and actively on your network.
A real problem when you have an AC unit that dies on you and is forever stuck in your app list and login. This is a basic feature and design consideration that should be included by developers.
They probably contracted development of the App to a third-party dev. to handle the app creation and are too cheap to update it or answer customer support requests.
