Is the room unused?

[felix63]

I made a generic script to check if a room has been empty for a specific period of time before switching off all the devices in that room. The basic principle is to have a PIR sensor and a connected group of devices.

Code: Select all

-- for each room you want to monitor add:
--
-- device:      [room name] .. ' beweging'   ; a PIR device to monitor movement in the room
-- group:       [room name]                  ; a group containing all the devices you want to switch off

local roomsToCheck = {
-- table with rooms to check and the minutes before the first warning is given
-- name:        [room name]
-- threshold:   number of minutes without movement before switching the group off
	{ ['name'] = 'Keuken',  ['threshold'] = 30 },
	{ ['name'] = 'Woonkamer',  ['threshold'] = 120 },
	{ ['name'] = 'Studeerkamer', ['threshold'] = 60 },
	{ ['name'] = 'Eetkamer', ['threshold'] = 60 },
}

-- 
return {
	active = true,
	
	on = {
        	timer = {'every 15 minutes'},					-- adjust this to suit your needs
    	},
	logging = {
        	level = domoticz.LOG_INFO,
		marker = "SRO"
	},

	execute = function(domoticz)
		for i, roomToCheck in pairs(roomsToCheck) do                           -- check all rooms in the table
			local name = roomToCheck['name']                                    
			local sensor = name .. ' beweging'                                  	-- get the sensor name
			local threshold = roomToCheck['threshold']                         -- get the threshold for this room
			local minutes = domoticz.devices(sensor).lastUpdate.minutesAgo      -- get the minutes without movement
			if (minutes > threshold) then                                       	-- do we need to do something
    				if (domoticz.groups(name).state == 'On') then           	-- anything on?
        				domoticz.log('No movement in ' .. name .. ' for  ' .. minutes .. ' minutes, turn everything off.')
                    			domoticz.groups(name).switchOff()                   -- turn stuff off
				else
        				domoticz.log('Everything in ' .. name .. '  already switched off.')
    				end
		   	 else
    				domoticz.log('Recent movement in ' .. name .. ',  ' .. minutes .. ' minutes ago, do nothing.')
            		end
		end
	end
