How can I set custom smart Home invocation, or call the default ones for set power level and adjust power level?
I have implemented the json I/O with the directives and responses, and it seems to be working in the lambda console. But when I try to use the voice commands, Alexa will say: "Hmm, I don't know that one."
I implemented these and they are working when I send json directives to my lambda, it sends back correctly formatted json responses.:
