Watchdog: Connection is down --> how to recover from this?

[djvanhelmond]

I'm reading the real time data from Tibber Pulse with the example real time from the README. After a while (I haven't detected a set interval, usually a few days) the connection dies and the Watchdog isn't in a position to recover from it.

Watchdog: Connection is down, 2024-12-03 09:50:55.895295+00:00
Error in watchdog connect, retrying in 20 seconds, 1:

It stays in this loop until I restart the script.

You may need more error handling than the test script.
For a real example, you could take a look at https://github.com/home-assistant/core/tree/dev/homeassistant/components/tibber
