I've created a script to determine if someone is at home (or not). It's based on if clients are connected to my Ubiquiti Wifi Network. So via the API I check if a at least one client is connected. I'm not a programmer at all, so most of the code is grabbed from several scripts and it's also a Lua script combined with a bash script.
I think it could be definately be cleaner code, but at least it's working. And it works a lot better than using Automatit or Tasker on the Android phones.
I'm using a dummy light to switch when someone is at home.
Lua time script to trigger the check.
Code: Select all
commandArray = {}
-- Call setHome when someone at home
if (otherdevices['homeSomeOne']=='On') then
os.execute('sudo ./home/pi/domoticz/scripts/bash/setHome.sh "On"')
print('called setHome / On')
end
-- Call setHome when no one at home
if (otherdevices['homeSomeOne']=='Off') then
os.execute('sudo ./home/pi/domoticz/scripts/bash/setHome.sh "Off"')
print('called setHome / Off')
end
return commandArrayBash script setHome.sh to call Ubiquiti API and switch the dummy light if needed:

unifi_logoutIn the future I will try to get the same result in LUA only but I'm not familiar using JSON and LUA. If someone has tips for improving it let me know.
