External power for motion sensor

Question

Hello,

Someone try to put any external power to Fibaro motion sensor instead battery?

 

I plan to replace existing PIR sensor with Fibaro sensor. Our existing pir is cable powerd and I plan to use that cable to power Fibaro.

 

Thank you

Hello Mediacut, 

 

This is on my list of things to do, I plan on using these instructions:

Hi, @Mediacut]

If you haven't purchased the  sensors yet I'd suggest you look at the aeotec/aeon MultiSensor6 as well.

It has an micro USB connector and even comes with a 2m lead. Depending on where you;re putting them there is also a flush mounting option (called a recessor)

I'm in the process of installing a dozen of these around the house and am powering them from strategically placed USB wall c=sockets like the following. It's working out very well

    , since i will remove all my existing PIR i have 6 wires for each that go to my technical room. In that room i have my old PARADOX alarm, and i will replace with a server PC Power supply, that has many outputs and high amperage and also i will use existing wires to power some Fibaro motion sensor and some smoke and leak sensor, and even my ipad's mini around house.

     

    Server output power supply has this outputs:

    1. 3,3V at 20A (enough for ~ 20 pcs motion sensor)

    2. 5V at 18A (will be used to power 4 ipad mini, that will be mounted in wall around home)

    3. 12V at 16A (enought for HC2 and for some smoke sensors and leak sensors)

     

    I will us this because has shot protection and is made for nonstop usage, is ventilated and i can even make my own redundant system based on two mounted and a contactor. So in case one failed second auto start.

     i'm new in Fibaro....i plan to use their modules...i'm afraid of communication issue with other modules. I never try other z-wave on this HC2, i just receive :). I found indeed a 6pc rail mount module...i need to test, but Fibaro offer a lot of parameter on their module, and that is a big + in home.

    I'm using powered Fibaro sensors for a long time without any issue. I just take a regular AC to DC convertor to 12V or 24V or whatever i have around the house and inside the motion sensor i put one like this:

    Works very well.

  • @Momos what is the voltage that you use on fibaro sensor?

    Same as the battery 3VDC. Those little step DC-DC converters as adjustable from 0.8 up. Very cheap and long lasting.

     

    Just saw your post: I also power some sensors from my existing paradox sensors.

  • i just order few for testing.

    I will try also to power from PC power supply....it has 3.3V hope not burn fibaro sensor....if burn i will use your advice.

     

    I will come back later with test results :)

  • I just test.

    Fibaro motion sensor work great with 3.3V DC powered like i promise from a PC power source. :-) So if you plan to whire your fibaro sensor, ipad, raspberry pi and HC2 you cand use only 1 power source from any junk PC.

    I did the same like @Mediacut, I have 2 former HP server power supplies. Made a modification to them to reduce the ventilator speed (and noise). Then I created a ring power supply through my house supplying 12V and 5V to power my sensors and led-strips. To add the Fibaro motion sensors to this power supply is a next challenge. Batteries ain't cheap anymore ;-)

  • Hehe, is not about battery price, is more convenient to have all powered from same power supply. In case of faults all is down :)
