# MQTT Button

This application will send an MQTT message when a button is pressed and released and can set a color to a button.

To use this application you should set the IP address of your MQTT server and the topic name in the "Settings" menu.

When a button is pressed a "on" will be send to `<topicname>/<buttonnumber>`. For example `/test/2` where `/test/` is configured as a topic name.
When the button is released a "off" will be send.

To light up a button send a hex color e.g. `0x0000ff` to `<topicname>/led/<buttonnumber>` and the button will light up in that color.

## Todo: 

- When a color is set and the button is pressed the color will be cleared. This should return to the same color.
- Configuration to set the 'push' color.
- Long press and double press messages.
- Toggle options for buttons.
