Low latency way to display volume?

In my build I’m looking to use a neopixel ring to display the volume setting for the amp. It would be ideal if I could get the volume level directly from volumio (to an arduino) to display on my neopixels with as little lag or latency as possible. I have noticed that in the web ui changes to the volume have a lot of latency and I was wondering if there was a way around this for my particular use case?


Use the websocket or REST getState API:
