Esphome binary sensor no longer behaving?

ESPHome

I have installed some ESP32s in some PIRs, all was working fine but now the PIR has stopped changing states. The tamper however is fine.

The Tamper changes state fine as is wired to PIN 27.

Its just the PIR that is not changing state, wired to PIN 26.

The tamper is Shorted (continuity) on Closed, open circuit on open.
The PIR is closed (continuity) when no motion detected, and open circuit when motion is detected.

Right now, the tamper is behaving as it should, however the PIR just wont change state at all.

Any ideas?

Thanks

maybe try this

binary_sensor:


  - platform: gpio
    pin: GPIO26
    name: "PIR"
    device_class: motion
