Alexa API Feedback

Hi Guys, I working on node-red integration with Amazon Echo (Alexa) and I have doubt how to send Turn ON or Turn Off feedback.

I didn´t find references on wiki Skill API each command I need to use. I found in google two possibilities TurOnResponse or TurnOnConfirmation, but both is not working well. The Alexa APP ignore changes, after turn on or turn off the button change to original state.

I using this nodes in node-red: https://flows.nodered.org/node/node-red-contrib-alexa-home-skill

I building this node structure to test:

[{"id":"adfbc2c9.5fb26","type":"alexa-home-resp","z":"521c6d66.acd1f4","x":700,"y":90,"wires":[]},{"id":"140ec653.1321da","type":"change","z":"521c6d66.acd1f4","name":"","rules":[{"t":"change","p":"command","pt":"msg","from":"TurnOnRequest","fromt":"str","to":"TurnOnResponse","tot":"str"},{"t":"change","p":"command","pt":"msg","from":"TurnOffRequest","fromt":"str","to":"TurnOnResponse","tot":"str"}],"action":"","property":"","from":"","to":"","reg":false,"x":470,"y":90,"wires":[["adfbc2c9.5fb26","d600314c.26298"]]},{"id":"df05a826.01df88","type":"delay","z":"521c6d66.acd1f4","name":"","pauseType":"delay","timeout":"3","timeoutUnits":"seconds","rate":"1","nbRateUnits":"1","rateUnits":"second","randomFirst":"1","randomLast":"5","randomUnits":"seconds","drop":false,"x":300,"y":90,"wires":[["140ec653.1321da"]]},{"id":"7d3505a.54695fc","type":"alexa-home","z":"521c6d66.acd1f4","conf":"652b1fd7.9687d","device":"56300","acknoledge":true,"name":"Living Light","topic":"Alexa - Living Light","x":100,"y":90,"wires":[["cd1baee9.5fc1c","d600314c.26298","df05a826.01df88"]]},{"id":"d600314c.26298","type":"debug","z":"521c6d66.acd1f4","name":"Living Light - Debub","active":true,"tosidebar":true,"console":false,"tostatus":false,"complete":"true","x":610,"y":30,"wires":[]},{"id":"652b1fd7.9687d","type":"alexa-home-conf","z":"","username":"aargollo"}]
