Is your feature request related to a problem? Please describe.

Currently, device configuration requires users to manually configure values that are already available from the devices themselves (e.g., from modbus registers). This creates redundant configuration work and potential for errors when the values could be read directly from the hardware.

Describe the solution you'd like

I'd like a feature that automatically reads configuration values from device registers (e.g., modbus) and uses them as internal defaults. This would be particularly useful for parameters such as:

• maxchargepower
• maxacpower
• maxdischargepower
• minsoc
• maxsoc

These values could be read from inverters, batteries, or other hardware devices. The registers could be read either once at startup or periodically at regular intervals if the values change dynamically during operation.

Describe alternatives you've considered

Currently, these values must be statically configured via UI or YAML. While templates can be used, they still require manually configuring values that the devices already provide, which doesn't eliminate the redundancy.
