Mentals Temperature Reactive Leds

Hello
Can someone explain to me how the macro
“Mentals Temperature Reactive Leds” working? M105 is only called once for me. Did I miss something?

Typically it is the job of the web-interface (Mainsail, Fluid, Octoprint, etc) to poll the temperature.
Octoprint is definitively using M105 to do so. I’m not sure about Moonraker-style web-interfaces, since they use a more advanced API.
Should they not be using M105 to poll temperature, then this macro would no longer work.

Thx, is there any alternate way?
