| How do users connect IOT device to WiFi? |

It’s probably cheaper to plan to run the server for 20 years than to engineer and customer support a way around that. |

ugh, I can hear the shelf calling my project back to its resting place. If I make an app instead of using a webpage for control, that would not solve this problen would it? |

There's really no need to have a manual way to enter configuration mode. Just try to connect with stored SSID/password, and enter configuration mode (AP mode) if connection is unsuccessful (or non-existent on first boot). Most common reason why users need to change SSID/password is if they upgrade their router, or move somewhere else. In both those cases, the connection will fail, and the user can put in a new one. If a power user wants to switch the device from one router to another, she can just turn the old router off for a moment and restart the device. This only doesn't work if the neighbour decides to set up a network with your old SSID/password that you can't power off, but this is rare enough that it's probably not worth worrying about. This is what the Chromecast does. |

Chromecast also has a factory reset mode. (Hold button for 25 seconds to forget all user data.) |

--- Quote from: sokoloff on September 30, 2019, 01:00:54 am ---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. --- End quote --- This seems strange to me but thanks for your explanation I guess it makes sense. I have no idea what to look for in a cloud provider. I dont think I need anything fancy. My products will probably need less than 10 bytes of data a day from each user. I'd like to get one at a price that works for very low sales volume but can scale if sales go well. What should I look for? Where is a good place to learn about servers or API gateways? |
