Detected blocking call to open inside the event loop by custom integration 'ocpp'

[Roos-AID]

Describe the bug Updated OCPP to 0.5.7 and to HA 2024.6.1 . Since then I get flood of warnings in log. The calling routine seems to be different in the different logs.

This is different than the previous reported flood that was fixed with 0.5.7

To Reproduce Update HA and OCPP to latest versions and check the HA log

Wallbox Pulsar Plus with Firmware: 6.4.14

Expected behavior No flood of warning errors

Different logs below (initial log at end)

Can confirm this with OCPP 0.5.7 and HA 2024.6.1. Charger is an EVbox Elvi. Worked stable beforehand. OCPP loses connection to the charger (or vise versa) every couple of minutes.

[drc38]

@lbbrhzn any ideas on how these calls can run outside the event loop or amended to run within it without causing errors?

I have this too with an MG Smartcharger (which shows up as a Star Charge). It is updated to as newer firmware as I can find (V1.1.2.7.6b107.1_C_003) and has never really created a stable connection to HA. I was trouble shooting it when I found this.

This may need to be fixed upstream see https://github.com/mobilityhouse/ocpp/issues/647
