In the new E3DC portal it is now possible to set the price limit for charging the E3DC battery.
This would be a great feature to get and set this value in Home Assistant to automate the charging of the E3DC battery.
In HA this will be more flexible (i.e. using automations).

Describe the solution you'd like

Enhance e3dc_rscp with a new method to set the price limit for charging the E3DC battery.

e3dc_rscp.set_charge_price_limit
data:
device_id: yourDeviceId
charge_price_limit: 0.000 - 999.999 (ct/kWh)

Add a new sensor "charge_price_limit" to show the actual price limit for charging the E3DC battery.

Describe alternatives you've considered

Meanwhile it is possible to set the price limit for charging the E3DC battery in the E3DC portal.
