Device is unresponsive

[AnimeshBote]

I have written response message correctly. Execution is successful for lambda event request.When I test it on emulator it returns me ok status but in the alexa app under device status it doesn't show updated status. It remains off and also I get device is unresponsive message. Please help with this issue.

[krishnu9]

did you solve this yet?

[AnimeshBote]

I think device will remain unresponsive because we are dealing with virtual device. I am going to try it with yee-light open API device.

[krishnu9]

Do you know how i can control devices connected to Arduino with this skill? I don't know how to send data to the mCu from the skill.

This could be because the ReportState directive needs to be implemented. Check https://developer.amazon.com/docs/device-apis/alexa-interface.html#reportstate and https://developer.amazon.com/docs/smarthome/state-reporting-for-a-smart-home-skill.html for more details.

Me too facing this issue. Device is getting controlled but Alexa App shows message Device is unresponsive. However Echo Dot is working as expected. I will implement the ReportState and check if it solves the problem.

I am having the same issue, when the device is controlled it succeeds. But I get the warning device is unresponsive. I've implemented the ReportState and I believe that works - when I open the app the state of the device is fetched. @pradipshenolkar did it solve your problems?

[Prasad491]

I am facing the same issue since long. Tried all the possible solutions to resolve an issue but couldn't.Although all the devices are included in the same group it is detecting only two devices out of four. I have connected lights through Wemo Device.

Similar or same problem here.

1. ReportState is implemented
2. Discovery and ReportState responses are valid for https://github.com/alexa/alexa-smarthome/wiki/Validation-Schemas
3. Bulb is shown with the correct state returned from ReportState
4. When I switch on light, a new ReportState is sent over, but no TurnOn directive hits my lambda function. The message Device is unresponsive is shown for few secs.

@AnimeshBote I am using a sort of virtual devices, too. I am emulating a real device via API. In theory it shouldn't make any difference for Alexa. Did you find any problem with virtual devices?

[mayank-kanzariya]

I have used SmartHome skill and implemented "PowerController" and "StateReport" interfaces for Bulb.

In alexa app display actual state of the Bulb.

Reference Link: https://developer.amazon.com/en-US/docs/alexa/device-apis/alexa-powercontroller.html

Note: I have used Alexa V3 APIs.

[pixelatedpic]

@mayank-kanzariya can you share some code for that two functions? i am also using virtual device and API v3. I want to know the flow. What i mean is after sending a TurnOn request for powerController do i have to send StateReport or i have to wait for ReportState request?

please solve my query am trying to setup the device responce but not working given below program

am requesting to please solve my problem what actually i want to do the

[rjpgt]

I was trying to wake up my desktop computer using the WakeOnLan controller. After quite a bit of struggle the skill started working but Alexa's voice response was that the device wasn't responding. After quite a bit of trial and error, I was able to solve this issue by not sending a deferred response. I removed deferred response altogether and it started working.
