I have a solution, this is how i manage solve this “irritating problem”.
I assume that you have a Z-wave base, mine is a raspberryPi with a razberry chip and with software domoticz.
You shoppinglist:
1pcs Inline Smart Energy Switch from Aeon Labs
1pcs Motion sensor from Fibaro
In sweden you can get all you need at www.m.nu
Aeon Labs – Switch
Fibaro motion sensor
And I use a LUA script named script_time_PIR-tv.lua. So after 20 minutes of inactivity in livingroom, the tv shutsdown… Simply as that!
function timedifference(s) year = string.sub(s, 1, 4) month = string.sub(s, 6, 7) day = string.sub(s, 9, 10) hour = string.sub(s, 12, 13) minutes = string.sub(s, 15, 16) seconds = string.sub(s, 18, 19) t1 = os.time() t2 = os.time{year=year, month=month, day=day, hour=hour, min=minutes, sec=seconds} difference = os.difftime (t1, t2) return difference end commandArray = {} -- Set length of time light should be on for in seconds timeon = 1200 -- Calculate time since time PIR was last activated difference = timedifference(otherdevices_lastupdate['Vardagsrum motion']) -- If the time since last activation was within 1 minute of time for light to stay on if (difference > timeon and difference < (timeon + 61)) then tempdiff = tostring(difference) tempmessage = "Switch1 Light Off - after at least " .. (timeon+1) .. "secs up - actually - " .. tempdiff .. "seconds" print(tempmessage) -- Switch off Switch1 commandArray['Tv'] = 'Off' end return commandArray
