Version of ESPHome / AIOsense ESPHome 2023.3.2 / 2.0.0 board

Describe the bug The esp8266 (D1 Mini) PIR pins are configured incorrectly as reported by esphome, GPIO13 does not have an internal pulldown

Failed config

binary_sensor.gpio: [source /config/esphome/.esphome/packages/6d7fe4d6/esphome/packages/sensors/pir.yaml:6]
  platform: gpio
  name: PIR
  id: motion_pir
  pin: 
    number: GPIO13

    Only GPIO16 supports pulldown.
    mode: INPUT_PULLDOWN
  device_class: motion
  filters: 
    - delayed_on: 0s
    - delayed_off: 1s

I managed to fix 2 other small bugs for the esp8266 (D1 Mini), I don't know if i should send a PR.

• ESP8266 does not have a CPU Temp sensor: https://github.com/CappyT/AIOsense/commit/61ed64bc3006f23a878852ec2ce1a7103066be0a
• ESP8266 led is inverted: https://github.com/CappyT/AIOsense/commit/4c86ee17a23e1bcfa27a9f8556a6ca67bb76b7f6

How can I fix the PIR sensor? I don't know much about electronics, I just know enough about ESPHome

You're welcome :)

ESP8266 are not in use at my flat, so I haven't test it yet. I've fixed the led and CPU Temp sensor based on your changes :)

I've also fixed the PIR (9111b0f). A pulldown is not really necessary. It's only there because someone has problems with there PIR (#52).

You can try all fixes by changing the refresh interval to 1s and recompile.

  remote_package:

    ref: main
    refresh: 1d  # <--- change it to "1s"

Thank you for the quick fix, however the PIR stays always on... this is my main file:

After some digging, the problem boils down to the pulldown input. It needs to be there to prevent "floating" (idk if it's the correct term in electronics). My board has this kind of issue.

I'd leave this open (feel free to close it if you want), but I would try to put a physical resistor in the board for ESP8266 compatibility, I'll let you know how it will go.

I just ask you, how big of a resistor I may need?

Hey @CappyT,

sorry for late reply. This is strange, because the PIR should pulldown the pin when no motion is detected.

Anyway, you can try a 4,7k resistor.

Good look :)
