Send pictogramm from HA to LED matrix

[riker09]

The Nuimo is a two-way device. Sensor input (like click, swipe or rotate gesture) is send to Home Assistant, the LED matrix can display information send from HA. There should be an intuitive way to send information to the display from HA.

@mwild1 created a small helper for that. You can draw a matrix and it gets converted into a string. You can find it here: https://matthewwild.co.uk/uploads/matrix.html
You can draw an icon there and it gets converted into a short text string. Enter that string in your automation, action or whatever and send it to the Nuimo bridge, the bridge should render it onto the matrix.

Optional parameter duration (with default value of 5s) after which the matrix is set to blank (saves battery)
