Hi Lénárd Pásztor,
after having replied on the post of Marek Klajman, I did some more test with the event "When voltage change value" and it does not work. I can show the calculated percentage on "On Start" but the value never change via "When voltage change value". I ran a 2 train motors for 5 minutes and the value never changes, however after stopping and restarting the project, the shown value has changed but not in "live"...
Can you have a look ?
Thanks.
