Amazon Dash

I discussed this in the project thread, but one thing to bear in mind: The dash button is a battery powered Wi-Fi device. There aren’t many of those, because Wi-Fi draws a lot of power, the battery life is typically terrible. For example the Arlo cameras usually have a battery life of three or four weeks.

As a replenishment device, I wouldn’t be surprised if Amazon spec’d these for a battery life of about 100 pushes. (In contrast, the low energy Bluetooth flic is spec’d at 60,000 pushes.)

You can try them and see, but before you run out and get a bunch for mission-critical switches, just be aware that they may have very short battery life.
