pulse(io, pulseTimeSeconds)
This function will cause the specified relay or register to pulse for pulseTimeSeconds seconds. The
relay parameter is the name of a relay and the pulseTimeSeconds is a number.
pulse(“io.relay1”, 1.5)
sleep(milliSeconds)
This function will cause the Lua script to stop executing for the specified number of milliseconds.
This function can only be called from the 5 Lua Scripts, not Lua expressions . If called from
Lua expressions, it will just return. This function is useful when a script needs to wait some time
before checking the result of a previous operation.

io.relay1 = 1
sleep(10000)
if io.relay1 == 1 then

print("Relay 1 is still off. We should have waited longer to check.")
end

0 = Host did not respond
-1 = Can't run from Lua Expressions

-3 = Internal Error
-4 = Timeout
-5 = Bad host name length

result = ping("192.168.1.15", 5)
if result == 1 then
print("Found device at 192.168.1.15")
elseif result == 0 then
