Shelly TOPAC (EVE01) device stop working

[pfassberg]

The problem

Suddenly the device stops. No new values are received and nothing can be changed. The device seems to be reachable. The logs show a lot of different errors most of them ends in "TypeError: 'NoneType' object is not subscriptable". The device work as expected using it's own web interface. Other Shelly devices using the same integration still works.

Additional information

A lot of the entities are doubled (some tripled). For example there is one "Phase A effect" working ("sensor.shellyevse_fas_a_effekt_2") and one inaccessible ("sensor.shellyevse_fas_a_effekt"). This happened long before the device stopped working so I'm not sure it's related.

If your issue is related to Shelly generation 1 device, make sure you have configured CoIoT peer correctly.
If your issue is related to battery powered Shelly generation 2/3/4 devices, make sure you have configured Outbound WebSocket correctly.
Please enable Shelly debug logging, let it run for 10-15 minutes, and make sure to capture whatever problem you're having in the debug log. Note: it is better to drag the log file into the comment (which will add it as an attachment) and not copy paste as it is hard to read logs in GitHub.
Finally, be sure to include diagnostics for the Shelly device you're having problems with.
