Fibaro motion sensor (zwave plus) heavy battery drain. Settings included. What's Wake up interval?

Hello guys,I'm using a Fibaro motion sensor in a lot of my flows.. But after changing some settings, the next day the battery was empty..

So I think that one of my settings are wrong.. I'm thinking of the wake up interval wich is set on 10 seconds while some others are having 7200 seconds or something like that. However, does this mean that the sensor wil report only once in the 2 hours? For movement by example, this is way too long..

But I don't understand it, because that is set under another item allready.. You can see my settings in the screenshots bellow.. Wich settings should I change?

Can someone help me please? Now I'm considering of buying an Eaotec multisensor 6 wich can also be used without batteries.. Anyone else know bte if that sensor is better than the  Fibaro?

    Wake up interval is just the interval in seconds in wich a battery operated zwave device will report to the controller when not active. My zwave smoke alarm has an interval of 21600 seconds. Wheb the alarm is activated (or in your case motion is detected) this is reported to the controller instantly. The battery drain is caused by the interval of 10 seconds I guess. Try something like above.

    Thanks for the info! But I do not understand why it should report while it is not active.. So also when the temperature changes, the lux change or motion has been detected, it will still report those things, also when the wake up interval is set to 40000 by example?

    It is the interval in which the device will wake up its zwave radio to receive settings/network healing/etc. If you set it higher then a day your device might get marked as lost, setting it too short will drain your battery excessively. Your device will wake up more often to do measurements, but will only power up the zwave radio when changes are detected and need to be sent to homey. The "rapportage grens" indicates how much a value needs to change before the zwave radio is powered up and a report is sent. Measurement interval indicates wake-ups for measurement. Report interval indicates at what rate reports are sent (at the minimum). Having a higher report interval then measurement interval is a good battery-saving measure as it will then report less often if a value sees little change.

    Looks like NEO app has standard of 21600, Fibaro at 7200. Why would u wanna change that to 10 sec?
    Put in a new battery and change the wake-up interval to 7200 and it seems to me there is no more battery drain no more.

    Thanks for the replies.. Set everything to normal, and wake up time to 7200, but the battery drains a lot. I bought a full one, and its now allready 48%. Can someone check the rest of my settings..? Anything strange?

    Ow and after I change the settings, I press the button on the sensor 3 times, and than press save.. This is the right way right?

    Rest of the settings up are the same as u have. Wake-up interval is at 7200

    @powermarcel10 there are a number of parameters influencing the rate that the sensor is reporting data.
    One of them is the "Illumination threshold" (aka Lichtsterkte rapportage drempel (lux)).

    In your screenshots, I see you have set is to 5 lux (default setting is shown in the hints).
    Meaning that every change in light intensity bigger than 5 lux is triggering a report.

    Depending on if you use the sensor inhouse or external, the light intensity will vary significantly. Inhouse between 1 - 600 lux and external between 1 - 4000+ Lux.

    My guess is that this settings is creating the additional traffing and therefore the battery drainage.

    You check your insights data for illumination to see the variation in light intensity.
