Why do I not see a switch state change?

ESPHome
1

I am learning ESP Home using a Wemos D1 Mini. I have a button between D1 (GPIO5) and ground. Here is the YAML file:

esphome:
  name: wemos_test
  platform: ESP8266
  board: d1_mini

wifi:
  ssid: "Kaywinnet"
  password: "806194xxxx"

  # Enable fallback hotspot (captive portal) in case wifi connection fails
  ap:
    ssid: "Wemos Test Fallback Hotspot"
    password: "Oi136ZHGIzON"

captive_portal:

# Enable logging
logger:
  level: DEBUG

# Enable Home Assistant API
api:

ota:
  safe_mode: True
  
# Switch on D1, GPIO5  
switch:
  - platform: gpio
    name: "Wemos_Switch"
    pin:
      number: D1
      inverted: False
      mode: INPUT_PULLUP

The log shows the pin D1 (GPIO5) as an input:

When I ground D1, I see no state change. What did I do wrong?

No need to open another thread. Stay in the original one. :slight_smile:

New ESPHome user- can't see a switch in the entity list

I thought of keeping the original thread, but that question is answered.

It should be a binary sensor if you are detecting something like grounding the pin.

A switch is to operate something external, like a relay attached to a gpio.

Thanks. I really appreciate your feedback. Patrick has been helping on the original thread. He didn’t say it quite as succinct as you, but he gave me an example to go from.

I saw the other thread was still going. If I was a moderator I would combine them. The switch concept is a little confusing, you would connect what we think of as a light switch to the esp as a sensor. But we still think of it as a switch, it takes some head exercise :slight_smile:

“… it takes some head exercise”
That’s the best description of YAML coding yet. :laughing:
