So i made a little luacode that i thought would help me out, it helps a little to much.

My problem is that the wallplug turns off after 30 minutes even when i don't forgot to turn of the coffe machine.

Another way is add "if" (to check again) before you turn off device.

Yes, but this will keep the instance open for the entire 30 minutes. Therefore, if you turn off the coffee maker and then turn it on again within the 30 minutes, the scene will still think that the machine have been on for the entire 30 minutes and therefore turn off the plug - even though it isn't supposed to. Therefore, you need to introduce regular status checks and then abort the scene if the status changes. That way, the scene will abort as soon as you turn off the machine and restart next time it is turned on. So you can make more than one can of coffee every half hour.

Dalle1985, sorry im not very sure. I always thought it will only trigger when this line is available.

local startSource = fibaro:getSourceTrigger();

if .....

startSource["type"] == "other"

)

No, as long as it is mentioned in the properties it will work. the fibaro:getSourceTrigger() will just return an array with information on what triggered the scene to run:

That way, you can have one scene with multiple triggers and different actions for each trigger, by reading the array.

You are asking the code to check if the TEXT "50" is larger than another text. How can one text be higher than another?

This won't do... It will always return true and therefore turn off the plug

You need to use numbers, i.e.:

This should do it for you...

My code does work, and so do yours, (i changed to yours to make it right) but i think my problem is that when the local timer starts, it wont put in new watt values from the plug, and because of that the plug goes off. Thats my teori, and how do i get round that if that is my problem?

[Dalle1985 15]

Yes, what your code does right now, is to say, if the value is >50 right now, it will turn off the device in 30 minutes - no matter what happens. I thought that was the purpose...

So you need to run a loop instead. So the loop sleeps for i.e. 10 seconds, then checks the value. If the value has dropped below 50, it aborts the code:

This isn't tested, but it should work (i cant remember if lua does countdown--, therefore countdown=countdown-1

Either way sonnyboy code does not have any trigger factor. How can the scene start?

Correct me if I'm wrong.

And perhaps what he means is he wants to check if coffee maker is on then turn off.

It triggers on change of valueSensor on id 35?!

@MalvinYNJ

It works my way, ill put in a little screen dump.

@Dalle1985

I will test your code when i get home tonight.

Tanks

I do essentially this with the basic block config, why do you need LUA?

[sonnyboy 11]

I tried with blocks and never got it to work, then i tried do it in lua but only got half the way, thats why,

[AtomicGrog 0]

Hmm ok well GL with it then.

My checks are slightly different, I'm looking to see when a TV centre is switched to standby and then I switch the power off if it remains unused for more than 20 mins.

Seems reliable, albeit I do two tests... one for W < 40 and the other for W > 0 (I found that at times the power meter aspects of my switched glitch and show 0)

[sonnyboy 11]

@Dalle1985

This is exactly what i want, works like it should.

Tanks so much for the help, i had ever come up with this solution

I'm trying to do almost the same.

I tried blocks and said, when tv w>5 turn on sub, media player and so on.

And another screen, when the tv w<5 turn off the things.

But nothing ever happens.

[Dalle1985 15]

Ahh... Convert to lua and try this code:

Where XX is the id of the tv and YY is the device you want to switch on/off. You can add more devices by repeating the three lines

To get more devices in. Just remember to put them inbetween the start and end markers for the devices

Thanks, looks not that difficult.

But when i try to create the scene, it dont get saved.

[Dalle1985 15]

Create a new scene, go to the advanced tab, press save as Lua and then input the script, remember to push the disc icon in the bar on the right hand side of the page when you are done to save it again. Do this every time you've changed something before moving away from the editor page...

just as i tried. but nothing is saved. not even when i just make a standard scene with no ekstra.

When i try to edit a scene and press Start after it, i get this error:

[ERROR] 21:19:22: LUA error: /opt/fibaro/scenes/4.lua:11: attempt to perform arithmetic on local 'deviceLastModification0' (a nil value)

[Dalle1985 15]

What exactly does your scene look like?

[swapsakker 0]

Looks lige this:

--[[

%% properties

28 valueSensor

%% globals

]]--

if tonumber(fibaro:getValue(28, "valueSensor")) > 5 then -- replace XX with device id for trigger

-- start of devices to switch on

-- replace YY with id of device you want to switch on when XX is above 5W

if tonumber(fibaro:getValue(23, "value"))==0 then

fibaro:call(23, "turnOn")

end

if tonumber(fibaro:getValue(26, "value"))==0 then

fibaro:call(26, "turnOn")

end

if tonumber(fibaro:getValue(29, "value"))==0 then

fibaro:call(29, "turnOn")

end

-- end of devices to switch on

end

if tonumber(fibaro:getValue(XX, "valueSensor")) < 5 then

-- start of devices to switch off

-- replace YY with device you want to switch off when XX is below 5W

if tonumber(fibaro:getValue(23, "value"))==1 then

fibaro:call(23, "turnOff")

end

if tonumber(fibaro:getValue(26, "value"))==1 then

fibaro:call(26, "turnOff")

end

if tonumber(fibaro:getValue(29, "value"))==1 then

fibaro:call(29, "turnOff")

end

-- end of devices to switch off

end

Now i get this error, and the config looks like this:

Error:Line 8: fibaro attempt to compare number with nil.

Line 8 is highlightet with BOLD.
