Binary Sensor reporting wrong in HA

Configuration
1

I have a home alarm system, I built a Wemos D1 mini a while back that detected PIR motion via a comparator to GPIO pins and sent via MQTT back to OpenHAB. I wrote an instructable for it 5.5 years ago https://www.instructables.com/Alarm-PIR-Movement-to-Home-Automation/

I’m currently migrating to HA :slight_smile:

I’ve setup ESPHome on the Wemos D1 mini instead and YAML code for binary sensor to report to HA, but am getting some varying results. The board is defined as d1_mini. YAML code for esphome is:

binary_sensor:
  - platform: gpio
    pin:
      number: D1
      mode: INPUT_PULLUP
      inverted: True
    name: "Alarm Zone 1"
    id: alarm_zone_1
    device_class: motion
    filters:
      - autorepeat:
        - delay: 2000ms
          time_off: 5000ms
          time_on: 10ms

  - platform: gpio
    pin:
      number: D2
      mode: INPUT_PULLUP
      inverted: True
    name: "Alarm Zone 2"
    id: alarm_zone_2
    device_class: motion
    filters:
      - autorepeat:
        - delay: 2000ms
          time_off: 5000ms
          time_on: 10ms
      

  - platform: gpio
    pin:
      number: D8
      mode: INPUT_PULLUP
    name: "Alarm Zone 3"
    id: alarm_zone_3
    device_class: motion
    filters:
      - autorepeat:
        - delay: 2000ms
          time_off: 5000ms
          time_on: 10ms

  - platform: gpio
    pin:
      number: D7
      mode: INPUT_PULLUP
      inverted: True
    name: "Alarm Zone 4"
    id: alarm_zone_4
    device_class: motion
    filters:
      - autorepeat:
        - delay: 2000ms
          time_off: 5000ms
          time_on: 10ms

Basically a separate GPIO for each PIR, low = motion detected, high = idle

Testing walking between Lounge (D1) and First hallway (D2), the HA zone “detected” gives the wrong results.

Walked past First Hallway PIR, HA Lounge triggers. Continue walking into Lounge PIR, it triggers HA Lounge. Walked back to first Hallway, it triggers HA First hallway. Stood still, then moved to trigger first hallway PIR and it set off HA Lounge.

(same symptoms without filters, that was testing) It’s quite intermittent. However checking ESPHome logs I see the correct GPIOs are triggered

Almost seems that HA is triggering the wrong entity, even though the correct zones are sent by ESPHome.

Any ideas?

FFS… never mind just went back over my original code, forgot I had configured it to wait about 5-10 seconds on boot up then turn on the comparator connected to D6… so had to add:

esphome:
  name: alarmzones
  friendly_name: alarmzones
  on_boot:
    - switch.turn_off: comparator
    - delay: 10s
    - switch.turn_on: comparator

# Comparator
switch:
  - platform: gpio
    pin: D6
    id: comparator
    restore_mode: ALWAYS_OFF
