Question about disconnection

[pamukcu09]

If the internet is disconnected while charging and the charger cannot connect to the server, how to re-establish the connection when the internet connection is restored?

Hi @pamukcu09,
I am having a similar matter.
Mine is in the direction on how to automatically reconnect once the connection is disconnected.
Connecting to a local CS (SteVe in the local network, without SSL) my clients stays connected for at least 1200h and more.
Connecting to a CS on the internet with I get disconnects after ~36hours and I am not able to automatically reconnect .

Any suggestion on how to code an automatic reconnect is very welcome.

How to automatically reconnect will depend on the library you use for websockets. I would refer to the documentation of that library and what the specific best case practice is.

[J0ergL]

I am using websockets as in the example.

Then I would refer to the documentation of the websockets library and look to see what the best strategy is for your application, as this is out of scope of the OCPP library.

The following code works in my case:

    try:
        cp = ChargePoint('CP_1', ws)
        await asyncio.gather(
            cp.start(), cp.send_boot_notification(),
            )
    except websockets.exceptions.ConnectionClosed as exception_error:
            logging.exception(
                'Websockets.ConnectionClosed(): %s', exception_error,
            )
            time.sleep(20)
            continue
