For a long time, I was looking for a substituation of the Amazon Dash button - you probably know that it can be used for other cool "IoT things" than buying stuff on Amazon... But there are so many downsides of the Amazon Dash button, e.g. you always need a computer (Raspberry) to catch the events, the battery cannot be replaced, and it's bound to certain users.
The 1btn has, in contrast to the Amazon button, a lot of advantages: - You need only the button, no other device is needed to trigger events - You simply setup 1btn using a web interface on www.1btn.space and can configure the action to do, e.g. call WebServices for example - The battery is recharchable - GREAT SUPPORT from the 1btn inventor
There are many things that the developer has thought of. it's possible, for example, to transmit the voltage of the battery and other variables when the button is pressed. As mentioned, the support is really awesome, you get help nearly immediately and some of my suggestions were also realized. One improvement for a future version could be a bigger "button" on the button.
Since the 1btn is a handcrafted tool -- it's assembled manually and the colorful casing is 3D-printed -- it's a bit bigger than the Dash Button. That's also the reason why it's not that cheap, it's of course simply not sponsored by Amazon. Considering the work and time for development, the price is quite fair.
If you buy the 1btn, you don't buy a simple piece of hardware but a very indivual little piece fine art. I recommend it!
I had no issues with delivery, and there was good communication throughout. I soldered on the headers, and it's charging a battery just now from USB. Documentation could be better, took a while to figure out I had to jumper the switch pins to get it to run from battery, but promising so far.
Thanks Stefan - appreciate your review and feedback. I have updated the user document today to reflect a few changes suggested by you and other buyers. Please have a look at it and suggest / comment if you have more suggestions.
Great product received on time with no issue. Very easy to start with and very good contact with the vendor. The board is great and I can't imagine all the projects I'll be able to do with it. It is modular and has great pre-wired functions such as the RGB led, the buttons and the battery charger.
