LUA script for logging

[Slinkos]

Hi all,

I have bought a PIR (Motion Sensor) and I want to monitor if it has false positives. So I was thinking to create a lua script that makes a separate log file somewhere, whenever my PIR is on and I am not home. It doesn't have to be readable within Domoticz, I'm fine with setting up a SSH connection and cat the logfile.

So I was thinking something like:

Code: Select all

commandArray = {}
if (devicechanged['PIR'] == 'On' and otherdevices['Home'] == 'Off') then
file = io.open("home/pi/domoticz/scripts/motionlog.txt", "w")
file:write(os.time "Motion detected while not home")
file:close()
end
return commandArray

But my experience in LUA is zero, so this will probably be full with mistakes. I don't see any errors, but I also don't see any file being created in the folder specified. The event doesn't even seem to be triggered.

I hope someone can help. thanks in advance.

Not sure why you want to do that. I never have had any false positives on any of my pir's. X10 or zwave.

Well, I have

I think you better find out why you have false positives. May be bad location of the pir. Sudden heat flows or so

Please just answer my question, this is not helping me. Logging it may help me finding out what causes it.

Logging is already present on Domoticz

But not the way I want it. If you don't know the answer that's fine. Then I hope someone else can reply.
