I have a problem with a "nodemcuv3 lolin".
I have 6 PIR with 2 wire, and each of this have 1 wire connected at GND of nodemcu and 1 wire connected at GPIO. In the normal state the contact of PIR is closed and I receive 0 (GND)
This PIR are connected in D1 D2 D5 D6 D7 and at D3 and configurated in ESP_Easy with internal pull up.

It work if I connect line D3 after boot, otherwise I have problem.

Are there best pratics to use D3 in this way??

Regards,
Dario
