Thank you so much for your code and explanation. I am a newbie to HA and I managed to set everything up as you do here. So I can read the entities from my wallboy and enable automation for the current value slider .
but my question is, now how do I effectively set the charging amperage through HA programming.
thanks in advance Walter Dekson
@walter.annaert : As shown in the initial post by @lemuba you need two things:
a) A slider to input the desired charge current (which you now have)
b) An automation that triggers on the slider (changes) and sends a command to the wallbox (see the post).
But maybe your question is: how do I automatically start / stop charging?
For this there are multiple integrations. The one that I use is EV Smart Charging which is available under HACS. It uses ‘dynamic pricing’ to find the moment of lowest electricity prices to charge the EV.
If you want to see how I used this, look at the post EV Smart charging with dynamic energy prices in the EU - Energy - Home Assistant Community
There are also Integrations that work with solor panels and home batteries. I have no experience with those.
Thank you for your response. My problem is that I am not familiar with programming in YAML. I always used the visual editor. So, I don’t understand how to change the charging current to, for example, 12A using the current value slider.
My intention is to make the car charge faster depending on the power generated by my solar panels. But i dont know how to do that in the YAML programming section.
Do you perhaps have a photo of how you do this, please?
It is not possible to copy what I have done. But…
You must have an Entity that measures the current/power generated by the solar panel. You can then create (using the visual editor) an Automation that triggers on state changes of this entity.
This will look a little like the following Automation I use when updating the slider:
Under ‘When’ is the trigger, which expands like this:
In the ‘Then do’ section you will set the current limit in de the wallbox using the modbus register. Like this:
Hello BrainDra1n, thank you very much! it works now
