Continuous discovery of new devices despite there being no new devices #71
Description
The problem
I have noticed over the last couple of months that I am prompted to add a VeSync integration despite all of my existing devices working properly and there being no new devices. I also apparently have a "failed to set up" failure, but all of my devices seem to work correctly.
I own 7 devices and all of them appear correctly. I have no new devices, but as you can see, the integration is prompting me to add four new devices. I have seen this before (though only ever one device) and when I click add, it has me sign in and then the box goes away; no discernible change to state.
With debug logs, I see the typical big blurb for finding the devices during setup (attached as file). I then get an error (apparent ID redacted):
Traceback (most recent call last):
File "/usr/src/homeassistant/homeassistant/config_entries.py", line 769, in __async_setup_with_context
result = await component.async_setup_entry(hass, self)
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
File "/config/custom_components/vesync/__init__.py", line 87, in async_setup_entry
hass.data[DOMAIN][config_entry.entry_id]["coordinator"] = coordinator
~~~~~~~~~~~~~~~~~^^^^^^^^^^^^^^^^^^^^^^^
KeyError: '<redacted>'
I also get the following (with debugging on):
