I am struggling finding a specific hardware, here is what I need :
- Bluetooth Low Energy Beacon
- good range
- Button on it to send a signal to my iOS/Android app
- Possibility to switch off/on (not mandatory)
- LED on it : It should receive signal from the app (to change the color, it - should show different colors of the LED)
- small max size 2cm diameter, 5mm thick
- cheap :)
I am not used to search IoT stuff and find it hard to find my way around, I tried alibaba but too many things, maybe you guys have some website to share.
