So what would you recommend as a wifi item? A lot of them seem to be crap, and don't you get issues with having +30 low frequency, low bandwidth wifi items added to your home network, along with the 30 other ones at your home already? How about remote exploits of those devices?

The fact that wifi 'can't handle a 100 small devices well' was sold to me as a reason to go z-wave 5 years ago.
