Guys, I've changed that configuration and it perfectly works !!!
Now I'm going to automate all the house...

Thanks for all the support and patience.

Guys, I'm adding this info to the thread just in case that someone may get this useful.

This is my final sketch:

Thanks for all the support and patience.

@martinhjelmare

Martin, I've added that line and now i can see the sensor as a switch on my HA web interface. The thing now is, when I trigger the switch from OFF to ON, the serial gateway sends the information to the node but the switch come back to OFF state. This is what i'm seeing on logs

Hi Martin, I've been reading a lot and still no lucky, can't see my node on the HA. Take a look to my sketch and logs. There's something wrong?

Thanks again!

What's the next step? I'm still not seeing nodes on my web interface... Where it's supposed to be located?

Thanks.

Hi guys.

I am new to mysensors and homeassistant. I've recently finished my gateway and my first relay node for switching lights on/off. Everything looks good, but I can't see my nodes on the HA web interface. What can I be doing wrong?

I've made this for the serial gateway: https://www.mysensors.org/build/serial_gateway
And for the node I've followed this: https://www.mysensors.org/build/relay (same code shown on the video)

this is my configuration.yaml:

homeassistant:
  name: Home
  latitude: NONE
  longitude: NONE
  temperature_unit: C
  time_zone: UTC

mysensors:
  gateways:
    - device: '/dev/ttyUSB0'
  debug: true
  persistence: true
  version: '1.5'
  optimistic: false

history:

logbook:

discovery:

frontend:

conversation:

First I've started my homeassistant and I see this logs:

after that i don't see any nodes on the web interface.

Thanks for your help and patience.
