Wallbox Support for Home P4

[julianrehm87]

Dear all,

does anybody has yet used the wallbox integration with a Senec Home.P4.

Since two weeks I replaced my previous Senec v3 with a P4 and the wallbox integration does not work anymore.

I understand that Senec Home.P4 only works via the WEBAPI integration and not via local integration. So i set this one up. Everything works fine here except the wallbox. Neither the switch of wallbox state nor the pure display of wallbox information brings up anything.

Thanks for your inputs
Julian

Hi Julian

can you enable the debug log output and check the output when try to toggle anything wallbox related... also important in your case is, that you disable the SENEC Local integration (the one for your Senec V3)

Hi Matthias,

thanks for your reply. Before I added this new integration entity I made sure that the previous one from my Senec V3 was deleted in HA.
So currently I only have the WEBAPI variant for my Home P4 in HA (Remark: Not sure if relevant, in mein-senec.de, I still have another Home P4 which is on error state. It is there because the first one delivered was defect and was replaced again. I asked Senec to remove it from my account but it is still there. In HA anyway I dont have this one integrated, just the working one.)

When switching the Wallbox loading mode, i receive some errors in the log, yes. I will send them to you via your github mail.

Cheers,
Julian

Moinsen,

I guess 'this' "kapoottt" P4 is the issue... since in the log you can find:

[custom_components.senec.pysenec_ha] app_update_all_wallboxes(): No valid wallbox data received or data is not a list 'False'

which is IMHO a signal that this device is not the one you want to configure [since there are no Wallboxes that can be found for the SystemID] - try to select a different 'AnlagenNummer' during setup of the Integration...

[julianrehm87]

As an update for this discussion, in the meanwhile i checked myself what the API returns and it really seems like this that for wallbox information, nothing is being returned for my Home P4.

Really would be interested if others have already used the wallbox integration for P4 successfully or if it is a general change here for P4 that nothing is being returned.

So the remaining qustions are...

Somebody who have initially purchased a P4 and a Senec Wallbox... If this works at all...

And how/via which endpoints the Senec App is able to communicate to your devices?
