LUA: Why lights is not Turn Off after 10 sec.

[kmeta 2]

Hello

I make simple script in LUA. The idea is:

1. If Lux < 250 and have movemeng Light turn on.

2. If no Movement more then 10 seconds and lights is ON then Light turn off.

First part works ok, but second part Lights turn off after 45, 60 sec.

Can you help me please:

kmeta, what value is set in parameter 6 in your motion sensor?

You scene only triggers on an event. So once triggered, it will run through and then exit. Then the next time it is run is when motion is cancelled (usually after 10 sec). But if motion is reset after i.e. 8 seconds, then the condition of no motion for 10 seconds won't be true. So now it has reset to 0 too soon, and the scene will only wake up on next motion event. You need to have a scene which triggers, turns on the light and then is kept alive until the light should be turned off. So basically:

- If motion true and lux<250, turn on light and set presence = 10

- repeat

-- Sleep 1 sec

-- If motion true, presence = 10

-- If motion false, presence = presence - 1

-- If light turned off, presence = 0

- Until presence = 0

- Turn light off

Now just do this as lua and then presence will be the period without motion until it should turn off.

Then you don't need to worry about source triggers or os.time or any of that either. Just make sure to include a check to only allow one alive instance at the start of your scene:

In general, this is good programming customs to avoid the same scene launching over and over again, filling up memory and dragging down performance.

Hi Dalle1985 your are right, but when i turned them manually they never not turn off. Another possibility is to add one more trigger (manually switch on) and to start countdown again.

But if the shut down time is 1+ hours maybe is not good to use resource just to count down manually.

I change this script like that and now is working correct. Do you have more recommendations ?

Well... The discussion has been up before, and no, it isn't the best thing in the world to keep the scene running, but it is more or less the only solution if you want off on a timer. I have a bunch of dimmers running on a somewhat similar scene. They basically turn on when there is motion, is then kept on at a preset level for 120 seconds after last motion event (meaning they reset to 120 whenever motion is detected). They then start dimming out slowly (1% pr second). If you turn them off manually they will stay off. I have seven of these scenes and in the evening, at least 3 are almost constantly on, and I'm experiencing no resource problems. So yes, it might be bad programming to keep the program alive, but there is no other way (that I've found) which will allow you to monitor the light state regularly.
