Love the idea. Having a platform for which devices can be easily routed for accessibility.
On the example of a scale being accessed by millions. I'd want to have a simple : PRIVATE / PUBLIC switch for this implemented. The concept of allowing your fridge to suggest food that would help you lose weight might be something to aid a user but shareing any of that with others sounds like a micro, or even macro invasion of privacy. And maybe your friends might not need this information but soon enough, large companies are going to be wanting to know how to better sell to the right customers.

Again, I find this idea & business attainable. With a name like Connyct. It sounds right & feels wrong. Its IOT, these off name companies are only a fad. IOTA / InsideOuT / IOTFeedr / idk, & seriously no offense. I have been studying Branding & Design, its become second nature to see a business for both its service & how well the name holds to its service. Cheers & good luck
