I have been playing with this today. Looks promising. Haven’t integrated it into home assistant yet, just playing with the homebridge container/ui. I can’t figure out if this actually uses the legacy nest developer account or not. I followed the instructions to use the dev account but only logged into my nest account.
Also, has anyone figured out how to get the nest hello stream into home assistant. I enabled a nest cam plugin on the homebridge container but can’t see a camera under the accessories.
