Doesn’t work with iOS 16
Useless waste of money
Not good
You can download the schedule to a blank app state and that (I guess) tells you how it is set but when it's not working you're left to your own devices to work out what's failing.
The links to help docs all 404 now so this seems like it's basically an unsupported product, which is funny as Bunning still sell it.
I would buy a different brand with nicer UX, better feedback as to what is going on and that is regularly updated. Not having diagnosis or even a basic manual in app is just lazy.
