Let's Control It

Calculate: Unknown token input: %eventvalue5% = 0

It seems that we could have only 4 parameters on an AsyncEvent
It that right or I miss something?

That's right.
It is a limit imposed by the traditional limit of 4 task variables.
However, I don't see why we shouldn't allow more event values as there are lots of use cases where more event values can be useful.

allow more event values

it would be convenient
Meanwhile, I'll split my event in 2, but could have some issues with the AsyncEvent...

Just added an issue for it as reminder: https://github.com/letscontrolit/ESPEasy/issues/3791

Thanks!
