This is my EspHoMaTriX version 2 (EHMTXv2) Example Setup that I got working with TeddyCloud, HomeAssistant, ESPhome and MQTT
I made this Post, as I will also post some of my Demo automations that was shown at the 37C3 Talk in this Video
But as first step, I would like to show how i setup my Ulanzi TC0001 with ESPhome and EspHoMaTriX V2 in HomeAssistant and ESPhome, this step is needed to Display Informations form TeddyCloud on it.
The additional needed Files are (linked from the original GitHube Repo:
