Debug logs for nest wifi and google wifi

 There are no logs available in the app, but there's quite a lot available from the diagnostic report API. It's in protobuf format, so someone wrote a handy little parser.

go get github.com/benmanns/onhub/cmd/onhubdump
~/go/bin/onhubdump http://192.168.86.1/api/v1/diagnostic-report > logs.json

$ jq 'keys' logs.json 
[
  "commandOutputs",
  "fileLengths",
  "files",
  "networkConfig",
  "stormVersion",
  "unixTime",
  "unknown1",
  "unknownPairs",
  "version",
  "wanInfo",
  "whirlwindVersion"
]

$ jq -r '.files[].path' logs.json
