hello,
i have a lot of problem with touchscreen for a while, i buy 2 elecrow panel 7", the first screen i bought work normally whithout the i2c PCA stuff and script, the 2nd one doesnt work ass expected and i found that put a aluminium film at the back work when i touch it with a hand, and the screen xith other hand...i used it like that for month...
I then decided to buy 2 more, to see if its a hardware problem, but no luck, the 2 new 7" the touchscreen doesnt work.
6 month after i search a lot and found this post with the link to 7.0-V3.0esphome.yaml, try it and now my touchscreen work on my 4 elecrow 7" without any trouble!

you're right, the script seems to be called anywhere...but it works ... Perhaps its called with the "touch" function...
anyway, thanks for your post, its work great for me now, on my 4 elecroc panel 7" !!!
