Devices

HomeSpanUI supports several devices.

Lights

LED (dimmable)

Single LED, dimmable.

8x8 Matrix - MAX7219 (up to three different combinations)

The matrix can show three symbols. The on/off led will be represented as bit code.

For example Pacman:

00111100
01001110
11001100
11111000
11111000
11111100
01111110
00111100

Convert the bits to hex:

3C
4E
CC
F8
F8
FC
7E
3C

Within HomeSpanUI you can use this to represent the light combination:

3C4ECCF8F8FC7E3C
