Hello to everyone,

first of all thank you very much for fauxmoESP. It works great!

I have a problem when I try to use the Alexa app with the manual switch, once I open the switch it shows it as on while is off and I can't change the status of it because it gives an error. If I use the voice command instead everything works fine. Can you please assist?

}

    // The later requires the Arduino Core for ESP8266 staging version
    // whilst the former works fine with current stable 2.3.0 version.
    // But, since it's not "async" anymore we have to manually poll for UDP
    // packets

You are using an old version of the library. Please switch to 3.1.0. You won't have the onGetState callback and you will have to use setState whenever you change the state of the LED from the manual switch to notify Alexa of the change.

Hi Xose and thank you for your reply.

The reason why I am using an old version of the library and of the board is because Alexa app wasn't able to find the switch on the latest version. I found on this site a post that was suggesting to downgrade both board and library to fix the issue.

I am using fauxmoESP with an Echo Spot.

Thanks

Did you read the Troubleshooting section in the main README.md on how to use the latest version?

Hi,

with the latest version of the library and a new example script everything works fine but in the Alexa app there's no button anymore. The device is not seen as a switch

That's right, it's seen as a light bulb instead.
