[pyShelly] Can't setup CoAP listener

[kongo09]

I just did a restore of a full Home Assistant backup after my system had crashed. Complete fresh install on a Raspberry Pi 4. Now I get the following error:

2021-09-02 22:40:49 ERROR (MainThread) [pyShelly] Can't setup CoAP listener

I'm running ShellyForHass 0.2.2

Some more context from the logs:

Traceback (most recent call last):
  File "/usr/local/lib/python3.9/site-packages/pyShelly/coap.py", line 28, in start
    self._init_socket()
  File "/usr/local/lib/python3.9/site-packages/pyShelly/coap.py", line 53, in _init_socket
    sock.setsockopt(socket.IPPROTO_IP, socket.IP_ADD_MEMBERSHIP, mreq)
OSError: [Errno 19] No such device

What does No such device mean?

Hm, I guess I solved this myself. I have a VLAN configured and use the configuration.yaml for the settings. When I did the full restore on a fresh device, the IP of the VLAN with my Shelly devices changed, so the configuration didn't match anymore, so the host_ip was not correct.

Fixing the host_ip to the new value and restarting HomeAssistant solved this problem. I'll close this now.
