2025.8.2 discussion

[myny-git]

Let's continue the discussion on the debugging of the HA integration. I copied the last items on the discussion, as that may be useful for everyone.

Original discussion

@gvnuland mentioned:

After restarting Home Assistant the version was visible. I have installed the version.
The update of the LED brightness is working well.
If I change the charging mode and I press the button "Set charging mode", then I got the message:

Tomorrow I will test the status update during charging.

==> The buttons may have changed name. So in Home Assistant, you should go in the integration, then select recreate entities. That may solve it. Version 2025.8.2

@dirkpiano mentioned:

Version 2025.8.2 (same behaviour as in 2025.8.1) : no matter what number I set in number.smappee_ev_wallbox_led_brightness, when I press the button.smappee_ev_wallbox_set_led_brightness , the Smappee app sets the number to 70%.
Also, no data is read from Smappee into the select and number entities, it always stays at either the default value or the value I set in HA.
All the other buttons work fine.

Hi thanks for testing. At my end, it works, surely with the latest release.

• indeed, I only updated the led and charging state from the app. The other number entities and select entitites are not updated from the app. I could evaluate this later, but then, we need to figure out which api-call we should do.
• The 70% is odd, I evaluated a few times today. What is important: the app does not refresh immediately the brightness. So you need to set brightness, move to another screen in the app and return.
  If it still does not work, please take a few screenshots or debutging logs.

I was also considering to swap again from number entity to slider, as that may be easier to control.

I just checked one of the curl actions:
https://app1pub.smappee.net/dev/v3/servicelocation/[servicelocationid]/smartdevices
It appears that you can obtain the value of percentage, not currents. I guess the currents are calculated based on the percentage input.

First thing to be done: retrieve min current, retrieve max current (same API call)
Then calculate the current from the percentage.
Then return both current and percentage to home assistant
Of course, there is a rounding error, as we are only allowed to send integers.

I think the LED brightness is OK now, after I reloaded and recreated the entity ID's.
I can control the brightness from HA, and HA reads the data from Smappee if it changes in the app.

The update of the status during solar charging is working well !!

[peterdedecker83]

Changing charging mode from SOLAR to NORMAL and back works without any issue. However, when in NORMAL_PERCENTAGE nothing happens when I change the current limit. Also no entries in the logbook appear about changing that current limit, whilst they do when I change the charging mode.

Hi Peter

thanks for all the feedback! I will update the docs to make it more clean.

However, I agree to you, that users do not want to set NORMAL_PERCENTAGE, they only care for currents (and eventually power).
That's why I optimized and cleaned up the code a bit.
I worked on it this morning, and found 2025.8.2b10 a stable prelease. -Use at own risk- feel free to test it and let me know if this would be better.

You would maybe need to reload or recreate entity-ids. You can always revert back to the original release 2025.8.2

I'll figure out, thanks!

For now (still with the previous release), I had some weird problems since this morning. Suddenly, the charger went into "error" modus when unplugged, or just didn't charge when plugged in, without a button in the app to start charging. Using the API calls didn't work either. When checking the app and going through the infinity modules, one of them had an error, but disappeared when clicking on it. Might have been a firmware update.

Since then it worked fine again, kept charging for hours whilst there was sun. When the sun dropped, my automation called your API/button to pause. Since then, resuming the charging session wasn't possible anymore. Nor through the API, nor through a button on the app: the app stated "cable connected" but no "pause" or "resume charging" button. Only when I set the charging mode to SOLAR and almost immediately afterwards back to NORMAL, charging resumed. Very weird...

[peterdedecker83]

OK, that session state "smart" is weird to me, never asked, and seems resulting in EVCC state E = error. Now again, no possibility to resume anymore. Latest messages in log are session state changed to "started" and evcc state changed to B...

[peterdedecker83]

Update, Smappee app displayed "fout" for max 2 seconds, now back the above shown screen... Manually setting strategy to SOLAR in the app and immediately back to "NORMAL" makes it work again... Weird issue...

Thanks for this extensive testing. I am now testing 2025.8.4 (with the slider, excluding the percentage). My first gutfeeling is that it's more stable. I will follow up in coming days.
