Fibaro Motion Sensor

[Guest pablotibis]

I just recently the "Fibaro motion sensor" via lua would like to make a condition like:

if (difference between last violation Motion Sensor and current date / time)> 30 min then

You know why the interface does not display the date / time last violation?

I just made this code,

it can check how long one or multiple sensors have not been breached, it saves it in the variable panel. In this way you can use in a scene if or how long you have been away:

It uses several variables:

Sleepstate

Presentstate

AwayMinutes

AwayHours

AwayDays

in combination with the following scene you know when you are away:

Couldn't you just check the device parameter called lastBreached (or something like that) and then just subtract it from the current time? When this value exceeds 1800000 (30 min * 60 sec * 1000 ms) then half an hour has gone between it was last breached and current time. I plan to use something similar to turn off my tv and dvr when there has been no activity in the room for 60 minutes.

[stevenvd 51]

You probably could, but i am running the Alpha and there the lastbreach is always 0.

[Dalle1985 16]

I just tested it. The lastBreached is the time at last breach in seconds since 1.1.1970. So I did a proof-of-concept:

The variable "diff" is the time between current time and last breached in seconds. So for 30 minutes you just do "diff*60*30".

*** EDIT ***

So I got inspired and made the scene. This scene will turn off plug with id 4 when 7200 seconds have elapsed since motion sensor 51 was last breached:

Thanks a lot, try these solutions immediately ....

Another question, I have a Roomba, the other day the motion sensor is activated by the movement of Roomba, is it possible? I need to change something? Today I do the test again and I'll let you know.

[Dalle1985 16]

Sounds. Bit strange. The detector picks up on temperature differences so only if a large "blob" of heat enters the sensors field of vision should it react. I don't know how hot the roomba gets (I'd like one, but it can't cope with the thresholds between our rooms) but I wouldn't imagine that it runs very hot?

I think most detectors just simply detect changes in IR radiation through a fresnel lens which divides the sensor into segments. When an object moves it leaves one segment and enters another which triggers the sensor as there are rapid and big changes in IR radiation. Slow variations are not detected but a detector usually does not care if it is a decrease in IR radiation or and increase. This means than when for instance a Roomba (even if the Roomba is room temp itself) passes by it may cover a spot on the floor which has been heated by the sun and this is detected as a fast decrease in IR radiation and consequently triggers the sensor. This is normal.

Why does the fibaro motion sensor video clearly show it being used on an outdoor patio? I'm sure we were told indoor use only!

I tried this on my patio and got constant false alerts until I moved it back indoors!

Any comments fibaro? In or out? If in only I suggest you modify your video!

Great explanation! I didn't know it segmented the room in that way. I thought it saw everything as one big segment.

[Guest pablotibis]

Confirmed again today reported roomba as a moving violation, that solutions could be adopted? any ideas?

I tried the test code, but in the line:

last = fibaro: getValue (51, "lastBreached")

fibaro by vacuum as a result and not a value? is a problem for my version? I have no display of last beta.

Thank you.

lastBreached is not availble in 3.5x version. Not in 3.901 alpha eighter....

So how can You explain that

IN GUI yes, but not when you run fibaro:getValue(122, "lastBreached")

Value is empty (0)

Ohh!

on one new motion sensor i did get the value but not the one i did test on first. Strange

I have it on all my detectors with firmware 3.580... But they are all Aeon... Perhaps it is different for the Fibaro unit? It sounds stupid that they would remove it... It is a very useful function! Perhaps someone should file a bugzilla on it? As I don't have the bug, I won't though...

[stevenvd 51]

I don't have a lastbreached for all 6 motion sensors in HC2: 3.901 Alpha

[jompa68 121]

Found out that it is different versions in my motion sensors.

Version 2.4 gives a value on last breach but not version 2.6

reported to bugzilla:

Solved with a restart of HC2, at least on 3.5xx version.
