Good evening,
I’im trying to integrate an R503 fingerprint sensor using a nodeMCU and ESPHome.
I have followed this tutorial:
But the sensor can’t communicate with ESPHome, I get the error “No response received from reader” and “Component fingerprint_grow was marked as failded”.
The sensor as a difference with the one on the tutorial: it has a brown cable instead of the green one, I don’t know if this can be the problem.
Also I can say that the fingerprint works perfectly with Arduino, so it is not broken.
This is my ESPHome yaml file:
