First, I’d be careful of the ‘cheapest’.
Second, I don’t like ‘app required’ to setup. But, I believe I do have some devices like that still. I’ll replace them as soon as I have an alternative.
I am a huge fan of complete self setup. App is bad. On device UI is good (as long as ‘internet’ is not required).
Thanks though for bringing this to the community. I am sure there are others that want this functionality and are less concerned than I am about what I posted above.
I get there are all kinds of situations for all kinds of users!
