Oh, and by the way August is one of the supported locks. I just added mine. Finally had enough with HomeKit automation just randomly failing, so I'm using Google Assistant Relay to open and close my August lock via their WiFi bridge. Yes it's cloud, but it works and I have to say, Google Home and August cloud are both really reliable.
If anyone is interested, I use
[CC] hey google, unlock the back door with security code ######
and
[CC] hey google, lock the back door
Really works well and is fast enough for the back door.
The [CC] prefix is a way of sending silent commands to Google Assistant using Google Assistant Relay.
