Amazon Dash buttons have entered the chat.
Yeah, but everybody knew those were a stupid fucking idea from the start. I didn't and still don't feel much sympathy for the people who deliberately bought one of those solely for its intended purpose and then got the rug pulled out from under them.
Amazon was effectively giving them away for free for a large portion of their lifespan. You'd have deals where you'd pay for them and then get a coupon for actually using them equal to the purchase price. I feel like I even remember a few times where the coupon you got worked out to slightly more than you paid for the button. Basically, saying that someone 'bought' one was usually only partially true.
They did have a few legitimately good uses. Had to have something that needed restocking sporadically but you also didn't think about often and could wait 2-3 days to receive when you realized you were out. A lot of prerequisites there, I used the ones for trash bags and detergent often.
It's mostly just a shame the amount of ewaste produced at this point. I still have a box full somewhere in hopes of finding a use case.
By "everybody" you mean everybody except Amazon. And I had fun hacking those. They were often on sale for like 2 bucks and they came with a battery that was good for like a thousand presses. You had to start the online setup process but not select any products, listen for the button's msg to Amazon which contained a unique ID. You could then have your own server listen for a "pressed" signal from that button and do whatever you want. I keep meaning to find out if there's still a way to initialize brand new ones.
That's pretty cool! What would you use them for?
I had a couple stuck on walls where I always wished I had put light switches. They toggled lights on and off using ESP-01 microcontrollers. Another one was in my daughter's bedroom where I had rehung the door to swing the opposite way so she could leave the door partway open without the hall light shining in her face in bed. As the batteries died I replaced them all with buttons run by newer ESP32s... if any of that makes sense.
What's the deal with these buttons?
