Hi, I am building wifi light switches to use with OpenRemote IoT smart home. Each light switch has a manual switch for local operation. The only way I could find to do this was with an interrupt to change the light to the opposite state. Using ESPlorer and running the program from snippets everything works fine. When I copy it into script file and save it to disc or load and run it, the interrupts don't work at all. I have tried many variations but always the same result.

-- init.lua --
--Wifi Remote light on/off switch with local switch
--for use with Openremote

-- Global Variables (Modify for your network) --

ssid = "*********"
pass = "***************"
port=2323--set port for each ESP
light=3 --GPIO0
switch=4 --GPIO2
lightstate="off"
sw=0
inInt=false

-- Configure Wireless Internet
wifi.setmode(wifi.STATION)
print('set mode=STATION (mode='..wifi.getmode()..')\n')
print('MAC Address: ',wifi.sta.getmac())
print('Chip ID: ',node.chipid())
print('Heap Size: ',node.heap(),'\n')
-- wifi config start
wifi.sta.config(ssid,pass)
-- wifi config end
