Hi Tom.
Are you using the WeMos D1 Mini?
Add the following before the detectsMovement() function definition:
ICACHE_RAM_ATTR void detectsMovement() {
Let me know if this solves your problem.

Hi Thomas.
Are you using GPIO 15 to control the relay?
I think that happens because GPIO 15 is used during boot. It must be pulled to GND during boot. See this documentation: https://github.com/espressif/esptool/wiki/ESP8266-Boot-Mode-Selection
I hope this helps.
Regards,
Sara
