Evcc Binding - electric vehicle charging control BACKPORT [4.1.0.0;4.2.0.0)

[the-ninth (Robert)]

Good morning,

Just installed the binding, I wanted to use it to build my own notification mechanisms, since those of evcc have some shortcomings. However one of the key channels does not seem to work, the vehicle title of the loadpoint. Is it just me, or is this broken?

[rbeudel (Ralf Beudel)]

Hello,
since EVCC 1.123.0 the key name changed from title to name. It should not fixed from the binding.

[the-ninth (Robert)]

You mean the binding needs to be changed to use the new key?

[rbeudel (Ralf Beudel)]

Yes, it is only one word. I tried to change the code, but I am not smart enough for that. In evcc github you can find the exactly word. I lost the place for the moment.

[florian-h05 (Florian H.)]

IIRC this has already been fixed in the evcc binding in the latest version, which is however currently only available as 4.2.0 Milestone 1 or SNAPSHOT.
Until then, someone would have to cherry-pick the changes to the 4.1.x branch and build a patched 4.1.x version.

Really annoying how often evcc has breaking API changes …

Great, thanks, then I’ll wait for this to be officially released!

@the-ninth

Great, thanks, then I’ll wait for this to be officially released!

That will be openHAB 4.2.0, which I would expect for end of July.
I know it’s a long time until then … I will eventually release a version with the backported adjustments to the marketplace until then.

Hi everyone,

currently I have trouble with the EVCC’s PvPower and VehicleTitle Items in my openHAB binding: PvPower is NULL and the string is empty all time. In the given interval when all other parameter are getting set, the vehicle title is updated to empty, PvPower is not set. I am sure there was a time it worked correct. Weird is that in the EVCC UI I can see the correct vehicle title and the correct PvPower - only in the openHAB binding I can’t.

My setup:

• openHAB 4.1.2 on RPi 3B+
• EVCC 0.125.0
• EVCC binding: 4.1.2

It doesn’t matter which car is connected. The problem is still the same with all EVs.
Anyone with the same problem? Any hints to solve my problem?

Thanks in advance!

[Grisnir (SB)]

Hi Jens,

I have the same setup, also with huawei-dongle-powersensor and see the same problems. With the latest evcc version 0.125.0, both PV Power and (Home) Battery Power/SoC dissapeared from the evcc Channels, I have issues with VehicleTitle a bit longer already, but that was not that important to me that I followed up on this.

I downgraded evcc to 0.124.10, now PV Power and Battery Power/SoC is working as expected again.

[Breezy (Jens)]

Thank you Grisnir! Good to know that I am not the only one with this issue.
Vehicle Title is not working longer than PvPower, I can confirm! I do not use a battery, that’s why I cannot confirm this statement.
For me the VehicleTitle is important as well, that’s why I don’t want to downgrade (which version worked with the title?). Hope there will be a fix in an upcoming version.

[rbeudel (Ralf Beudel)]

EVCC changed VehicleTitle to VehicleName and some other things. When you read this thread, there is explained what will happen.

[Breezy (Jens)]

I cannot find anything concerning renaming VehicleTitle in this topic (and yes I tried CTRL+F).
I switched the channel to VehicleName and now the item is NULL (instead of empty string with VehicleTitle).
In the bindings documentation, the channel is named VehicleTitle as well. May you can give me a hint?
Thanks!

[rbeudel (Ralf Beudel)]

@Breezy

In the bindings documentation, the channel is named VehicleTitle as well. May you can give me a hint?
Thanks!

You cant do anything until the binding is updatet.

[fanavity (Patrik)]

Do oyu have an idea when the binding will be updated? Or i have to downgrade

[florian-h05 (Florian H.)]

Hi @fanavity,

thanks for the heads up - totally forgot about backporting the changes to the 4.1.x evcc binding.

There we go:

Release evcc backport for openHAB 4.1.x, version 01 · florian-h05/openhab-addons

I wil soon update the marketplace post above, so it should be possible to install this binding from the marketplace - however due to the marketplace rules, I don’t want to set is as published, so you have to enable the “Unpublished Add-ons” option in the “Community Marketplace Add-ons” settings.

[wars (Ward)]

I installed the binding from the marketplace and everything works fine, except the channel loadpoint<N>#phases.

loadpoint<N>#phases	Number	RW	The maximum number of phases which can be used

I can send a 0 (auto-switching), 1 or 3, and this is immedialty changed in evcc. so far so good. But the item itself always stays on 0.
So it seems the status is not coming back properly.

Other people have the same issue?

I’m running evcc 0.203.1

[Nodiaque]

Hello,

I’m on 0.207.1 nightly and the binding stopped working. It says “communication_error request failed” but when I enable trace, it does query and get the information back:

[Oggerschummer (Thomas)]

Check the evcc release notes. There was a breaking change in the result format, requires adjustment in the binding.

Afair an obsolete result wrapper has been removed.

It had been announced some weeks ago.

Stick to 0.206, it has the same features as 0.207
