I have this endpoint with powerState and connectivity properties both retrievable:
{
"endpointId": "123",
"manufacturerName": "abc",
"friendlyName": "lamp",
"description": "lamp",
"displayCategories": [
"LIGHT"
],
"capabilities": [
{
"type": "AlexaInterface",
"interface": "Alexa.PowerController",
"version": "3",
"properties": {
"supported": [{
"name": "powerState"
}],
"retrievable": true
}
},
{
"type": "AlexaInterface",
"interface": "Alexa.EndpointHealth",
"version": "3",
"properties": {
"supported": [{
"name": "connectivity"
}],
"retrievable": true
}
}
],
"cookie": {}
}
I respond to ReportState request by sending the state of both properties:
{
"context": {
"properties": [
{
"namespace": "Alexa.PowerController",
"name": "powerState",
"value": "ON",
"timeOfSample": "2019-01-10T10:17:19.99Z",
"uncertaintyInMilliseconds": 50
},
{
"namespace": "Alexa.EndpointHealth",
"name": "connectivity",
"value": {
"value": "OK"
},
"timeOfSample": "2019-01-10T10:17:19.90Z",
"uncertaintyInMilliseconds": 50
}
]
},
"event": {
"header": {
"namespace": "Alexa",
"name": "StateReport",
"payloadVersion": "3",
"messageId": "cde",
"correlationToken": "efg123"
},
"endpoint": {
"scope": {
"type": "BearerToken",
"token": "ab123"
},
"endpointId": "123",
"cookie": {}
},
"payload": {}
}
}
And I send the same context in the PowerController response. In the Alexa app I can see my device, turn it on and off and view its state rightly. I can ask Alexa to turn on and off my device and the response in "OK", but if I try to ask:** "Is my device turned on?" ** Alexa answers that this device doesn't support that.
The skill language is Italian and PowerController documentation https://developer.amazon.com/it/docs/device-apis/alexa-powercontroller.html says that query is supported.
What am I missing?
