DIN rail controller JetHome JetHub E1 v3.0

The JetHome JetHub E1 DIN rail controller has undergone a hardware update in version v3.0. The update affected both the AC and the DC versions.

The key difference in v3.0 is the use of a PCA9535 port expander chip instead of the previous PCF8575. This update improves the controller's port expansion capabilities. It is also worth paying attention to the firmware configuration, which differs from version v2.0 due to the use of a different driver.
