Cannot see energy flow dots

[Tangiers2020]

Hi, unless i have missed something simple, i cannot see any energy indicator dots moving along the line.
Screenshots tell me it's a thing but cannot find anything in the documentation.

Hi. Can you share your config. The animations are enabled by default and uses the max_power: and animation_speed: attributes for each of the sections. They have default values assigned for it to work.
