#56232
So, the problem I have is: I created a lua script to control a lightswitch with commands send to a tcp-server running on the nodemcu or by pressing the normal lightswitch. But after a while the nodemcu is not reacting to any input on the GPIO pin.
I don't know if you understand what I mean, my english is pretty bad.
So I connected stuff like it follows:
nodemcu controls a SSR to switch on/off the light.
schalter = the "pushbutton/switch".
And then there is a switch (like a pushbutton) connected to ground and D1 (gpio.mode(schalter, gpio.INT, gpio.PULLUP))
And this is my code:
What I tried to fix the Problem:
use a timer (see the tmr.alarm in the code) to "reconnect" the GPIO.trig() function -> not working.
stop lua garbage collection -> not working.
change the GPIO pin mode to INPUT and leave PULLUP away (every possiblity) -> not working.
I have no idea what I could try, perhaps you know what makes my code fail.

--Version 1.1: UPDATE and REBOOT working now. See #730 for fixing idea.
--Version 1.2: Added SSR reacting to interrupt on pin 1 (D1).
--Version 1.3: ChipInfo command + debug messages for connected TCP Client.
--Version 1.4: Send messages to all connected Clients.
