CC3220SF: TIDM-1020: Thermostat not responding.

Part Number: CC3220SF


After fixing the lambda handler to "lambda.lambda_handler", Alexa App was able to discover the Thermostat. But when I say "Alexa set Thermostat to 28". It replied back "Sorry, Thermostat is not responding".

But, I see this at Tera Term log below

"Delta - target setpoint changed from the cloud!"

So, seems its working


  • Hi kel,

    I suggest you take a look at the lambda logs on cloudwatch to see what may have gone wrong in your test. The logs should display the received Alexa directive as well as the response passed back for every Alexa request you make.

    If you look at the response given back and compare that to the expected Alexa schema, do you see anything obviously wrong there?



  • Hi Michael,

    I see the cloudwatch logs but I am not familiar with it. But at CCS debug I was able to confirm the targetSetpoint variable changed, so it works.
