Camera Shows as "<null> Camera"

[davet9713]

I've got two registered Nest cameras in my account, with two rooms "Front Yard" and "Dining Room"

For some reason when the cameras enumerate in the plugin, "Dining Room Camera" comes in OK, but the other camera displays as " Camera". I've noticed in the Nest app that the "Where" location of that camera has two fields.. one for the Room (Front Yard) and a second field for Label (empty). I've tried setting the label to something other than blank but it has no effect.

When attempting to view this camera, most times it will be "No Response" when touching the placeholder Nest image and the log looks something like this (stream and oauth codes changed to "..."). Sometimes repeatedly backing out of the "No Response" screen in Home app and retrying will yield a stream that works for a little while before becoming "No Response" again.

You can actually make the <null> Camera thing happen in the Nest app and the Home app! For newly added legacy cameras they will often show up this way if there is no label. This happened to me when I recently bought a new old stock outdoor cam from eBay.

After setting the label to something you will probably need to clear the cached accessories in Homebridge and restart.

As for the 404 error, see this case: #4

[davet9713]

Yeah, I tried setting the label and the clearing all cached accessories before I filed the report... it still comes through as " Camera". The only difference is that the one that works without issue is an old legacy Nest branded indoor Camera that's a couple years old, the one coming through a is a newer Google branded Nest outdoor camera (wired not battery) that I purchased last month.

@davet9713 : Ahh. Fair enough, I don't have one of the new cameras. It's possible they are reported differently in the API. The problem with developing a plugin like this is I can't add features dependant on specific Nest devices if I don't own one myself. You could always lend me yours :)

[davet9713]

If I do a device list from the Google side and send you the output, would that help?

I’ve changed the room in Google Home from <null> to Front Yard and it prompted me to remove room <null> as it had no more devices in it.

Hi @davet9713, yes I mentioned in one of my previous comments that the <null> label is visible in the Nest or Google Home apps in some cases as well, particularly when adding a new camera. Glad you sorted it out, I will add it to the FAQ.
