Hardware topology

[Piglet]

Hello to everybody!
I'm new in here, so if i post in the wrong thread,topic i m sorry.
I recently start to design a automatized growing environment. It s all based on a Raspberry pi zero w and an ESP32. I ll use Home Assistant to get everything done.
Uploaded picture shows the hardware topology, and it s pretty intuitive. I post to ask if somebody have some recommendations or some advises to make everything more cost efficient or to design it better.

Thanks

Price list do not include the price for LED lights and the interface screen cause i still didn't found some reliable and cheap parts.(if some idea, i ll be happy to hear).
On the drawings is missing the screen. I just noticed

First recommendation is to use diagrams.net for future diagrams. Free and fast and better looking

Are you using ESPhome?

Yep, i plan to use ESPhome add on from HAS. I still don t know how i ll setup everything, but i see that the community is big and helpfully.
I ll try today diagrams.net and i ll revert with a better looking diagram. Thx!!
