Reading multiple tacho signals separate #15

Have you ever tried to read multiple tacho signals to check individual fans RPMs?

I've been looking at a lot of these kind of projects, the way tach/sense is done would require a pin per fan. Not sure how to implement it here, as I'm just now getting my brain around the fundamentals...

Here is an example with 2 fans. https://github.com/patrickcollins12/esphome-fan-controller/issues/10#issuecomment-1403371213

You're right @CzarofAK. Two fans need two separate pins for the tacho. I have not personally implemented the tacho so I didn't notice this error in the diagram.
