> The issue is more about connection to external servers than the particular board itself.
Oh I meant that the R.Pi would be the server where the IoT gadgets connect to. Located in your home and available through your home network connection. Optionally with some kind of (self-hosted) server in your own VPS.
This is obviously a solution for DIY-ers only.
> Consumers want to, and indeed they do, pay for these devices.
I don't think this will ever work if the customers pay for the devices but not for the service. A $99 gadget doesn't leave much for the company to be running the service. I don't see how the economics would work out without a recurring payment.
My gut feeling is that gadget startups such as this one haven't even thought about surviving more than 3-5 years without being acqui-hired to a major corp. Some may bet on getting to be big and thinking that scale will help.
But even if every darn garage in the world would have this gadget for the $99 they charge, I can't see how they can keep the servers running and the software up-to-date with a one time purchase for the life expectancy of an average garage door.
But consumers complain about recurring fees and there's only so many services you can subscribe to. Paying $2-$10 a month for your garage door, thermostat, cat feeder, plant waterer, etc will add up to a lot of money and hassle.
The only way I see forward with cloud-powered IoT gadgets is that a major company with billions of dollars sets up the infrastructure that will scale up to millions of users with a few billion gadgets (and a monthly fee). It's either that or self-hosted DIY. I don't think it's economically viable for a start-up to provide a cloud service for a one-time fee for any meaningful period of time.
I'm sure customers don't want to buy and install a new garage door opener every 3 years when their previous IoT gadget startup goes belly up, servers go down and the gadget turns to a brick.
