NodeMCU does not reboot

[emme]

uh... got an issue

I discovered that my nodeMCU (MySens gtw + temp sensor + rain sensor) does not reboot...

well it does only if I unplug the rain sensor that is a NC contact con D4
...id D4 used for other stuff than a simple DI contact? I could not find anything on it... just find something about D1

D4 is GPIO2 this has to be high at boot.
D3 is GPIO0, also has to be high
D8 is GPIO15, has to be low.

thanks...
looks like I have to change D4 to something else... or replace the NC to a NO switch
