If you need legacy hardware clock support, you will need to downgrade the firmware on the controller to 5.0.1 and 3.x on the WiFI module.
The 4.x versions of the WiFi firmware use network time and include a new scheduling system and the framework for multiple daily schedules.

I can downgrade the main board firmware to 5.0.1 but not wifi to 3.

You need to install a DS3231 clock chip in IC2.
OK. will try To get this part.
can this one also fit ?
other then that - do I need any thins else ?
The aliexpress part is not correct.
You could use this module.
You would need to fabricate a connector to go from the clock board to the second i2c port on the display.
