HDMI on HA Yellow

Hardware

Has anyone soldered the micro HDMI connector onto the HA Yellow PCB?
Does it work?

Hello Pelican,

The Home Assistant Yellow while loaded with HAOS will only display the CLI text (command line interface) stuff to the screen, so it doesn’t much matter. It doesn’t need to be 4k res for that.

Hello

Thanks for the reply. I want to use the Yellow to drive a kiosk type screen, so I really want HDMI out of that interface.

I had a look at the schematic and the PCB and it looks like the HDMI lines from the CM4 come out on the micro HDMI footprint. If I can get HDMI working by soldering on a connector, it will be great.

Hello

Now I get what you meant :man_facepalming:. Is there no way to get the GUI? It kinda sucks to have to get another device just to render the dash when there is a Raspi in that box

Home Assistant OS (which runs on the Yellow) has no GUI. I haven’t tried it yet on mine, but if you really want to get console output you should just try a USB-C to HDMI adapter. But even then, you will not ever get a GUI out of it.

Thank you for your response. I know HA doesn’t have a GUI, so I was hoping to run a browser on the Yellow. Hoping to be lucky, I did try a few USB->HDMI adaptors, but it didn’t work as the OS would need drivers for that.

I really don’t understand the negative attitude against running the dashboard on the same machine. Home assistant is a product that is targeting exactly the type of group who likes to tinker. Otherwise somebody buys an ecosystem from Aqara, Xiaomi, Shelly etc. and just uses it. So if somebody wants to run the dashboard on the same maschine, feel free to do it and ecourage it. I have read on several threads on this forum and also on reddit, when such comments came up, alway there was some “wise guy guru” who shouted that HA is meant to be run headless. Okay, I understand that this is the way the majority prefers. But why are you forcefully restricting the users to think and use HA in the same way. It’s artifically created like this and I really don’t understand this attitude against using it differently. Why am I not encouraged to install debian on it, run HA in a docker container, and put besides a wayland or x11 gui with kiosk browser on it. The CM4/5 has it, and it’s really up to a HDMI connector. Is it really that expensive ? I mean, the HA yellow itself is quite expensive, it contains the Silabs chip, and the rest is power supply and passive components + connectors.
Put on top of it the price of the CM4/5, it’s far from being a cheap product. And it’s quite powerful board to just limit it to run “HA OS headless”.
