Hi @hugobox , I came across your led bargraph flow, thank you very much for sharing your code which seems clear, elegant and concise.

I am trying to turn it into just a row of leds with minimal template code that just accepts as input an array of colours in a single msg.

I am getting an infinite Aerial digest loop error but their help and explanation unfortunately does not mean anything to me.

Could you or anyone else here please give me a hint as to how it can be declared and implemented.

Best regards oz
