How do users connect IOT device to WiFi?

<< < (12/14) > >>

sokoloff:
Think of it this way; your users have overwhelmingly configured their home network such that devices on their network can reach the internet. Far fewer of them (almost none) have configured their network to allow inbound access to your device.

Take advantage and make use of this natural condition. Run a server (or API gateway) in the Internet. You can do that super cheaply and easily nowadays with any number of cloud providers. I happen to have chosen AWS, but loads of options are other there.

Kasper:
Even if it is easy and cheap to run a server, does that not mean I have to keep it running through the lifespan of my product?

sokoloff:
For users to use whatever functions require internet connectivity, yes.

Kasper:
That'd be a 10 - 20 year commitment. Are there really no other options?

mDNS resolves names on the LAN. UPnP (where permitted) enables the firewall to translate requests from the WAN address to the LAN address space. The problem is that the WAN address is not guaranteed not to change from day to day. Users may not know their home IP address from day to day, or properly, the address of the WAN interface on their router from the perspective of the global Internet, and may not be inclined to set up their network for a dynamic DNS service of their choice (no-ip, Dyn, etc.). Perhaps your UI can offer them a way to automate that setup, but then you're depending on you and/or the companies who offer it collectively maintaining a 10-20 year commitment to those services.

One other option is to just be like Revolv, get bought by Google, and let them take the heat for bricking your product  :-DD
