Question Regarding Gauge Cluster Widget

[wayland]

Hey there! First off, I want to thank everyone so much for this amazing software. It really is super useful and has brought new life to my old car.

I had a quick question regarding one of the marketed extensions/widgets for hudiy. I noticed that you show this analogue speed/tachometer/navigation cluster running on a separate display on your YouTube page as well as the main GitHub repo, but I haven't been able to figure out just where the template for this is. Also, I wondered what would be the best way to modify the look of this (maybe change the background and add a digital read out of the speed), and if there is a way I could modify it via my computer without having to re-upload it to the head unit every time I made a change (as I assume it is a HTML/JS file integrated with the Hudiy API).

I bought a cheap display I am going to integrate into my car's dash in place of a few analogue dials and connect as a second display to my main Hudiy head unit, and I thought this would look super nice.

Thanks!

Hello,
Thank you for your kind words. We are glad to hear that you enjoy using Hudiy.

The items visible in the screenshot are available on our GitHub https://github.com/wiboma/hudiy/tree/ma ... les/api/js. You can find an example configuration on our forum showing how to display them on the Hudiy interface using overlays: viewtopic.php?p=212&hilit=tacho#p212

The tacho and speedo examples use the Hudiy API, which allows you to easily communicate with the ELM327. You can also modify the HTML/JS to use your own data source - in that case, Hudiy will simply act as the display.

To run the HTML/JS examples that use the API, you must serve them via an HTTP server due to the Same-Origin Policy (browser security) - https://developer.mozilla.org/en-US/doc ... gin_policy

For editing code directly on the Raspberry Pi, we recommend using Visual Studio Code with the SSH extension. You can run Visual Studio Code on your computer and connect it to Raspberry Pi via SSH extension: https://code.visualstudio.com/docs/remote/ssh

Awesome. Thank you so much for the detailed information. I must have missed the configuration example you linked on the forum the first time I looked through. Really appreciate it
