[SOLVED] LightwaveRF lights unavailable

1

I have a number of LightwaveRF 2 light switches. Usually they work fine, though recently homeassistant randomly stops being able to control them (I say randomly as I they’ll start working the next day).

The hub is connected, and I’m able to control the lights with the lightwave RF app.

If I look at the entities in the LightwaveRF integration page, I see that the lights are “Restored”, but if I look up a light in developer tools they’re showing as unavailable, and I see the following error in the logs:

2022-01-30 18:47:15 ERROR (MainThread) [homeassistant.components.light] Error while setting up lightwave2 platform for light
Traceback (most recent call last):

    self._lwlink.get_featureset_by_id(self._featureset_id).features[
TypeError: unsupported operand type(s) for /: 'NoneType' and 'int'

Any advice as to next steps/possible avenues of investigation would be most appreciated!

Kind Regards,

Solved this myself with a bit of debugging: I’d replaced a switch and the integration had disabled the assosiated entities, and the disabled entities had “None” for every property. Removed lightwave integration, restarted HA, re-added integration: Problem solved.
