ABB Terra AC-W22-T-0 Bootloop

Describe the bug ABB Terra AC-W22-T-0 (listed as supported) keeps booting with these notifications showing up. Controls are avaliable for a few seconds, until it reboots again.

Screenshots

Versions etc. OCPP v0.5.8 HA 2024.8.1 Charger firmware: V1.8.21 (Newest)

Debug logging from HA (Not really sure if I'm including enough?)

I also have a lot of notification with my ABB Terra. I use this automation to cancel them but I would also be interested about a bug fix...

I have the same problem with my Terra AC W11 and Firmware 1.8.21 I downgraded to OCPP 0.5.6 ad later upgraded to 0.5.7 and it works again without reboot loop. Problem starts with 0.5.8 as far as I could find out

I am having the same issues on my ABB Terra AC-W22-T-0 (also running the latest firmware 1.8.21). I can also confirm that the issue seems to disappear when downgrading to OCPP v0.5.7

Stumbled into the same issue when testing HA OCPP integration. Have the latest firmware 1.8.21 as well.

What happens is that the charger gets into the bootloop after issuing

send [2,"91b546e6-de46-4ed5-b48b-6a0d7b38b991","GetConfiguration",{"key":["MeterValuesSampledData"]}]

That bootloop, I think, is caused by initial configuration of HA OCPP. When adding my charger, as a new user, I have accepted all the defaults. On the first boot, I had logs like these:

Notice that ABB charger happily accepted all kind of measurands despite not supporting them (based on ABB Terra OCPP 1.6 Implementation Overview )

However, after reboot, it was not going that smoothly. As soon as GetConfiguration for MeterValuesSampledData is requested, charger reboots. This can be observed via LEDs on charger too. HA logs:

So, I think what happened, is that we have not these chargers with wrong configuration in MeterValuesSampledData. These chargers, btw, seem to support only 5 and rather specific ones: Current.Import,Energy.Active.Import.Register,Power.Active.Import,Voltage . Related issue: https://github.com/lbbrhzn/ocpp/issues/1279 . When it tries to retrieve the values, it probably gets some kind of buffer overflow with the current setup.

Suggested PR (#1290) doesn't really help, as the charger bootloops leading to:

Not that we can use configure service directly either, as it will ask for current configuration first.

What helped, was to force applicable settings somewhere in the beginning of the try block before measurands are probed:

            _LOGGER.info(f"'{self.id}' setting measurands to default values")
            req = call.ChangeConfiguration(key=key, value="Current.Import,Energy.Active.Import.Register,Power.Active.Import,Voltage")
            resp = await self.call(req)

and commenting out all that autoconfig of measurands. Would have to test bit tomorrow as well.

The best solution would be for ABB to correct the issue in their firmware, otherwise you will need to create your own fork of the repo with the above changes to workaround the issue.

Agreed, correction of ABB firmware would be the best solution. Would have to contact ABB and make them aware of it.

However, with such type of devices as chargers, we are expected to stumble on bugs in the firmware. In addition, forking this repo for ABB chargers would fragment the development instead of making this implementation as a one to use by many. Thus, I propose to handle these types of errors in this repository.

To fix this bug, I would work on PR that will:

[ ] Add a configuration option to disable automatic detection of the measurands. This will be permanently enabled for ABB chargers and others that could have similar issues.
[ ] Add a quirk to set MeterValuesSampledData to the one specified in configuration by users. It would have to be used by users who have got their chargers into the same state as mine (I would expect it to be few based on this issue, as well as issues #1263 and #1126). Later, users can disable it when the charger is working properly.
[ ] Update documentation on how to configure ABB Terra AC charger.

Will try to work on this tonight.

@rinigus that'd be a good solution, it was talked about shortly after the switch in logic to v0.5 but not implemented. I'd suggest adding an options flow to allow for reconfiguration of parameters after the initial setup.

@drc38 just saw your feedback while working on PR. It would be great if the options could be later changed as right now we need to remove and add integration for it. However, I am new to HA and it would be my first contribution to it - so let's start with what we have :) . Will learn by doing and maybe in time I could add options flow. But, I suspect that someone will beat me to it.

Current state is submitted as PR. Would have to add a quirk, docs, and do more testing. Will continue working on it tomorrow.

Sounds good @rinigus. I take it ABB has been notified of the issue as it is a serious flaw in their firmware and as a reputable company you would expect them to issue a fix reasonably promptly.

@drc38 Re ABB contact: not yet, but will do it. Added it into TODO list for PR.
