Requesting for help building traffic light led module node

[airmedic79]

Hi!
I'm trying to build a traffic light led module node on a arduino pro mini 5v. I am currently using a temperature/humidity node without a problem with raspberry pi ethernet gateway.

Below is the sketch I'm working on. Its function is only to toggle in home assistant. When uploaded, it seems to be communicating with the gateway but doesn't show up in home assistant.

I'd like to know if there's something wrong with the sketch.
Thanks in advance!

You need to send the initial state of the sensor

@electrik Wow! You gave me a clue! Thanks!!

Hi airmedic79,

I think it should be temperature/humidity node design connection issue lead to not show up in home assistant,
do you have compressed files?maybe you I could do your favor for this item design,tks.

I am sharing my sketch. Based on the sketch below, I am using this led light to show air quality status (good for green, normal for yellow and bad for red). This sketch is just a switch so you should make some automation in HA.
