Scene that runs only if the light level is below a user set

[emariu 0]

I found some LUA code for VERA that would run a scene only if the light level is below a user set threshold :

local LOW_LEVEL = 20 -- the light level threshold for night

local DEVICE_NO = 33 -- the light sensor device number

local LS_SID = "urn:micasaverde-com:serviceId:LightSensor1" -- the LightSensor service ID

local currentLevel = luup.variable_get (LS_SID, "CurrentLevel", DEVICE_NO) or 0

currentLevel = tonumber(currentLevel)

if currentLevel <= LOW_LEVEL then

return true

else

return false

end

Can someone tell me how can I implement this function for HC2?

Hi there,

What is your setup?

I do not have a light sensor but I am using HC2 built in sunsethour and sunrisehour functions to enable/trigger certain devices at home. These functions return the correct sunset/sunrise hour based on the longitude/lattitude you specify in your location settings. Add a margin to those hours and you can perfectly achieve something similar without the need of a light sensor.

As for a light sensor, I would assume that you can simply add it as the first condition in the visual scene builder: IF LIGHT SENSOR <= NUMBER (where NUMBER = the amount of lumen, 200 for example) THEN do stuff.

I have an AEOTEC 4-1 with light sensor ,so I want to light on a lamp if the lumens are below 125(stormy days are dark, so sunset isn't a good option for me).

I didn't realize that I have visual scene builder: IF LIGHT SENSOR <= NUMBER ..so I tried to do the scene but when I select light sensor >= there is only ON/breached/armed .... options,but don't let me input numbers for actual light conditions.

So,what option do I have ?

I have a scene that sets a global variable to brigh or dark depending on the lux reporter by 4-1 sensor.

I then have other scenes that will use this variable. For example I will turn on outside light if it is dark and not night.

I use lua in the scenes, i don't know if you can do it with the graphic block style

Please send me the LUA code that reads lux reported..Iwant to use your exact code..Thanks

[Guest b95_lun]

Here the code that reads the lux value and sets the global variables

Device 45 is the 4-1 sensor

Global variable = ljusUte (Swedish for light outside). Has two values mörkt (dark) and ljust (bright)

I then have other scenes that watch this global variable and takes action when it is changed.

I hope this helps

"Device 45 is the 4-1 sensor" ...is not device 41 the light sensor?

What is this for :"local iOsDevice =42" ?

What changes do I have to do for this to work with my device?Here: "trigger["deviceID"]" am I supposed to change anything?

Thank you again for your help

Sorry I was a made a typo, 41 is the sensor.

The iOSdevice was the id for my iPhone, I used a push notification for testing proposes but it isn't used any more.

The changes you need to do is the sensor id (change 41 to your sensor id) and change the global variable (ljusUte) and its values unless you want it in swedish.

I changed that and after I had pushed the RUN scene button and I got some error response : [ERROR] 13:44:10: line :getValue (arg 2), expected 'unsigned int' got 'nil'

[ERROR] 13:44:16: line :getValue (arg 2), expected 'unsigned int' got 'nil'

Maybe I was not supposed to push the RUN (or Start) button

Is the scene supposed to run on every HC2 restart?

[Guest b95_lun]

Hi,

As the scene isbuilt you can't run it.

The scene is triggered by a change of the value of the sensor

The definition of the variable trigger requires that a change of the valu has happened.

when you use run no change of the value has happened thus the local fibaro:getSourceTrigger() will be nill and you get an eror during execution.

All is working fine now, very happy
