> The battery should last for approximately 1,000 presses. When the device battery runs out of charge, there is no way to recharge or replace the battery. This limits use cases to infrequent-press applications.

  As pointed out in the comments there, the button will not ship a second order until the first one has been delivered. You will get a notification email each time it is activated so you can cancel an order. It's also trivial to deauth a particular button.

This is interesting, since from teardowns it looks like there's literally just a AAA battery in there: https://mpetroff.net/2015/05/amazon-dash-button-teardown/ https://mpetroff.net/2015/05/amazon-dash-button-teardown/

  Yup, but they decided to weld the contacts of the board to the battery. I'm guessing that they calculated it was cheaper (or more business savvy) to get users to replace the button every X months/years than to make the button in such a way that the battery is user replaceable and also indicates charge level.

    It also means they can reasonably assume there aren't 10 year old buttons using an ancient protocol out there to support.

      Sometimes planned obsolescence is a good thing.

      You'd have to order an awful lot of toilet paper to have it only last 10 years. Even at a rate of one-press-per-week, it'll last getting on for 20 years.

        The sample use cases for these buttons is more frequent use than the Dash "order me something" ones.

        But do they use a different protocol?
    - dexterdog 10y ago
      It's a thing with an ID that sends a single event. How much can the protocol evolve?
      - ceejayoz 10y ago
        Maybe the next version will have a thumbprint scanner so it knows who initiated the event. Maybe multiple buttons will be in a mesh network and send data about the other devices they're in contact with. I highly doubt we've seen the final feature set for IoT buttons.
