I found this project AWtrix which is a poormens “LaMetric”. It is very cool and consists of a server which “renders” the display data und an controller (ESP8266) which displays the data on a 8x32 matrix.
When FASTLED with matrix support is incorporated in esphomelib one can get rid of the AWtrix-server and push the information directly from home-assistant to the display.
In the meantime AWTrix evolved a lot. Now it has got a cool mqtt-api which fits to home-assistant. So now you can use awtrix nicely from hass.io. So this feature request has a quite low priority for me.
Just started looking at the LED matrix I had lying here, and stumbled on your post, wow, that is very interesting. I’ve ordered his small board, can’t wait to get this up and running
