Switching charging from grid on and off

[LudgerMi]

Describe your feature request

The app SUN2000 offers in the section 'maintenance' the charging of the battery from the grid. I cannot find or I did not understand how to switch on and off charging from grid with the home assistant integration. I would like to request the feature controlling of charging from grid.
Background: During winter time I need to buy electrical power from the grid. I would like to use a provider who offers dynamic prices for electrical power. I know someone who developed a HA integration for the provider ‘tibber’: Getting the current price and starting charging of his EV.

Proper usage

• I confirm that this is not a bug report or support request
• I confirm that this feature request is within the stated scope of the integration

You can use the services exposed by this integration to start a forced charge:

If you need to prevent your battery from discharging, you can set the maximum discharge power to 0 .

Dear Thijs, thanks for support, it works now, I'm very satisfied!
Please apologize for inconvenience. I saw the announcement of these services, but I did not realize the connection to charging from grid.
Regards Ludger

Excuse my ignorance but I cannot work out how to navigate to that forcible charge screen shown above. Please could you give me the directory to it?

[LudgerMi]

Select Developer tools and Services. To find the service enter forcible Charge

To create a button, which you place on the dash board I created a script: Settings --> Automations & scenes:

thanks very much for your help - extremely helpful. the one last part of the puzzle I'm struggling with is how to trigger the charge when another device does something. I want the home battery to grid charge whenever my EV charge starts charging, and stop charging when the EV charge stops?

[LudgerMi]

In order to avoid misunderstandings: In this thread there is a discussion of force charging the home battery from the grid (AC), not charging from the solar panels.
Charging the home battery from the grid is a use case during periods, when you do not get sufficient power from the solar modules and you want to buy electrical power from a provider who offers lower prices during the night.
Please tell me know, which kind of charging you have in mind, then I can provide you further information.

sorry for not being very clear. im trying to set up an automation whereby the huawei battery charges from grid when my EV charger starts charging (i have a dynamic energy tarrif specific to EV's). my EV charger is HACS integrated to HA and I know I'm using the right sensor on the EV charger (tested it with notifications). as per the screenshot below the automation I want is - 'when' the EV charger load goes above 500w 'and if' between 5:30am and 11:30pm 'then do'.... I cannot find the right action from the list list to trigger a charge from grid? the action i've selected in the screenshot doesn't work?

[LudgerMi]

Ok, now I got it. In the graphical Editor for automatisation you can directly call the service 'Huawei solar: Forcible charge'. Please see below the example: When I open my kitchen window then start charging from grit:

Unfortunatelly, I cannot test it now, because we have a sunny day today and my batterie is already full. I let you know this evening.

You can also select 'Forcible Charge of the battery to a certain State of Charge level'
