Emberchip

Emberchip generates firmware for inexpensive microcontroller boards from a short YAML file: sensors, switches, displays and LEDs become local-network devices your hub discovers automatically.

Worth knowing before you commit:

• No cloud, no app store — devices you flash are devices you own.
• Over-the-air updates make iteration painless after the first flash.
• The component library covers a startling range of cheap hardware.

The gateway drug from buying smart devices to building them.
