HomeGraph ReportState issue

[shady2k]

I have issue with HomeGraph. Error occurs, when mqtt message received.

In log file: 2018-12-21 08:29:06.078 +03:00 [Information] MQTT message received for topic openhab/stateUpdates/switch_hallway/state: OFF 2018-12-21 08:29:29.113 +03:00 [Error] Unhandled exception while handling application message.

Error in GoogleHomeGraphClient, line 182: var signingCredentials = new SigningCredentials(securityKey, SecurityAlgorithms.RsaSha256Signature);

System.NotSupportedException: "IDX10634: Unable to create the SignatureProvider. Algorithm: 'http://www.w3.org/2001/04/xmldsig-more#rsa-sha256', SecurityKey: 'Microsoft.IdentityModel.Tokens.SymmetricSecurityKey' is not supported."

googleDevices.json

{
  "google/home/switch": {
    "id": "google/home/switch",
    "type": "action.devices.types.SWITCH",
    "willReportState": true,
    "roomHint": "Some Room",
    "name": {
      "defaultNames": [],
      "name": "my switch",

    },

      "manufacturer": "Some Company",
      "model": "Some Model",

      "swVersion": "1.0"
    },
    "traits": [
      {
        "trait": "action.devices.traits.OnOff",

        "state": {
          "on": {
            "topic": "openhab/stateUpdates/switch_hallway/state",
            "googleType": "bool",
            "valueMap": [
              {
                "mqtt": "ON",
                "type": "value",
                "google": true
              },
              {
                "mqtt": "OFF",
                "type": "value",
                "google": false
              }
            ]
          }
        }
      }
    ]
  },
} 

I tried to change RsaSha256Signature to HmacSha256Signature, but after that I have error in MqttService at line 110: System.Net.Http.HttpRequestException: "Response status code does not indicate success: 500 (Internal Server Error)."

What I am doing wrong?

You aren't doing anything wrong. I don't use ReportState so this hasn't been fully tested... you just get to be the lucky first person to see how broken it is.

I completely missed that the cert they send over here is just the private key PEM file essentially... which .NET doesn't have native support to read. So it's gonna take me a day or two to find something that can read it and get it patched in. Hang tight.

Just released 1.0.0.66. Should be on DockerHub momentarily. Try that out and let me know what you get.

[i8beef]

Scratch that, 1.0.0.71 or whatever is latest. I had to fix some Docker build issues and move to .NET Core 2.2.

[shady2k]

Thank you. No errors in log now. I'm keep testing it.

Excellent! Let me know how it goes, and close the ticket when you're satisfied.
