ABB Tera AC w22-T-R-O - all entities are 'unavailable'

[NiiiYaa]

Hello,

I have a charging unit ABB Tera AC w22-T-R-O.

I'm trying to connect it to my Home Assistant Via the HACS OCPP integration.

• HA version - Core: 2024.9.0 | Supervisor: 2024.08.0 | Operating System: 13.1
• Version of the custom_component OCPP- v0.5.9
• No YAML configuration was added/created.

After following the documentation steps/instructions, a new integration was added:

Accordingly, 2 device were added:

The 'central' device has no entities:

The abb device has 52 entities, which all of those (expect one) are grayed-out (unavailable):

I cannot find any error logs related to this...

What do I do wrong? Can someone kindly please assist me

Thank you in advance, N

Not sure if it's only ABB related, but after upgrading HA to 2024.9.0 mine w11 stopped working.

I suspect it is related to #1275. At least that was an issue with my charger. Fortunately, there is a fix and its submitted: #1292. We have to wait a bit for review process to get it sorted out.

If you want to test it, you could use this branch: https://github.com/rinigus/ha-ocpp/tree/config-autodetect-measurands Note that this branch has also updated documentation regarding ABB chargers. Please read it first.

Until the fix is applied, I would suggest to switch off the charger or connect it somewhere else. If it is the same issue as #1275, your charger would be bootloop'ing otherwise.

This seems to unrelated to HA update, WIFI connection issue.

Please test with the latest OCPP version (0.5.11) and follow instructions at https://home-assistant-ocpp.readthedocs.io/en/latest/supported-devices.html under ABB subsection. I hope your issue is fixed.

The workarounds described in the link worked for me. Charger firmware V1.8.21 and OCPP v0.5.14

The workaround with disable automatic measureands works somewhat for me as well.. It does, however, often give me the "StartupOfTheDevice" notification. Today it stopped reporting back and I saw the following in my logs.

Firmware 1.8.21 as well
