Alexa can't discover the device

[notSoTechnical]

1. I have the 3rd gen of Echo dot, so I'm wondering whether that's the reason it doesn't work. 2. Both of my LEDs on my one channel relay were on after I upload the code to the node MCU board. I think on the red LED (power indicatior) should on. The green LED should be on only if I ask Alexa to turn it on.
2. Every time I power the MCU board, sinric.com showed my IOT device was connected (a good sign)

I'm very new to this... Any help is appreciated!

1. I assume you have installed the Alexa Skill and completed the linking.

2. When you ask Alexa to turn on/off a device created in Sinric do you see the command appear in the Arduino console ?

if doesnt work post the code here without api key

Hi Kako,

Thanks for replying.

The output (a screenshot) from the serial monitor when I made the command (talk to Alexa): https://photos.app.goo.gl/RhMsgE8eGixd92Lc8

1. did you link the skill successfully ?

2. void setup() { Serial.begin(9600); // <-- should be first and then set to 9600 according to shared pic. otherwise print junk

rest of the code seems fine.

Thank you! Here is the output: https://photos.app.goo.gl/PSPtaaKW2zUUQbT5A

But both of the LEDs are still on the whole time. The green LED was off while I was uploading the code to the board. It turned on after I was done the uploading. It never turned off even after I made several commands.

Any idea why?

[kakopappa]

OK so Alexa part works.

What;s the dev board you are using? if you are using this code it's using only GPIO 5.

Set all the GPIOs to LOW and see how it works out

[notSoTechnical]

This is the wiring and hardware: https://photos.app.goo.gl/ubkGECj78nVm6mLJ9

V+ from the Node MCU is supplying 5V to the relay.

The red Led is the power indicator; green LED is off only if I remove the brown wire (the wire that is connected to GPIO5 or D1)

Hi Koka,

It's working now after I changed the relay model. Thank you so much!
