Using a Wemos D1 mini with HA and ESPHome (latest versions).
I am using a 3v input to identify a PC being On or Off. Unfortunately, it always shows as ON, even with the wire disconnected from the input pin. Any ideas? The ground is common between the 5V ESP power source and my 3v input. I have confirmed my 3v input is changing as expected (3v with the PC On, 0v with the PC Off). I have tried a second Wemos D1 mini with the same results.
I must be missing something Thanks for any help!
