ESPhome stops reading Modbus values

The problem

Hi all,
I am not sure if this is related to the last week esphome update, but most of my devices reading modbus stop working/reading last thursday. They stay online but are not reading anything.
I tryed to read the PV inverter directly from my computer and inverter still providing info on request.
So problem should be in my esp soft/hardware.
I've discarted hardware becasue it is strange serveral devices connected to different esp, stops simultaneusly.
Maybe it is related to the last esphome update.

Any idea?

Problem solved!!
Seems like last esphome update dated on mid July 2025 did break the communication and new code was required.
Changing framework type from "arduino" to "esp-idf" everything was solved. Just compile and udgrade the code via OTA.
Now all the different esp reading modbus 485 through TTL are working properly.
