Accessing Mode Schedule Parameters via Modbus?

Hi.
Anyone knows if it's possible to access the mode schedule settings using the Modbus interface?
I'm looking for a way to control my H3 inverter based on tariffs but I don't like the idea of fixed recurring schedules.
However, if setting the schedules is the only way then I'd like to be able to change this locally via Modbus.
Any ideas?

No schedules are not exposed over modbus, you can get to the via the Fox cloud OpenAPI.
If you’ve got modbus control you can control workmodes to achieve the same thing using the ha scheduler card.

Thank you for clarifying this!

I'm doing it by setting the work modes via automations, and using the battery SoC as a guide for which mode I want to put it in. So for example, towards the end of the day I gradually discharge the battery by using force-discharge as the evening progresses, following a desired SoC curve so that it does not empty out too early, or too late. You can get as complex as you like.

I would be very interested in seeing your automation code. I am trying to do something similar although not as sophisticated, just to export the surplus at the last possible time.
