Thanks for the advise, in fact some people tell us that they need something, but after you make it, you'll see other people don't need to it, and even those people who told you that they needed it, don't need it any more, and then, you will stay alone with what you have made!hi MA,
I would advise you to think about IoT devices that would fill a 'need' , not to create a IoT device and try to create a market 'need'.
You are tackling the problem back to front.
