Oh dear! The harder I try the more confused I become. Moved it all into 1 room. Decided that *obviously* it could all run off 1 psu . But it doesn't work!!!. Sensor power in is off the same psu that's the only difference ( both are rated at 12v 5A output). Sensor is recognised, but when the doorbell is pushed no 'changed' state occurs. Gone back to 2 psu's and it's ok. I just don't get it. Is it something to do with GND????

Looking at the door built in leds . 12v transformer . Stick my meter on it get 12v as expected . Swap my probes and get -12v . I’m confused ! Assumed I’d get 0 ; if that were true I’d then use sensor input in2 to control the 0 ( gnd? ) line . But it’s not . Erm - confusion reigns again !! How long before I bust my sensor ! ?

Right ! This is how I think I’ve got it wired !! I don’t need 2 psu’s . The ‘doorbell’ is in one room ; where I’m fiddling with the sensor another ( long cable inbetween ! ) . My ‘logic’ is ... The sensors default state is ‘open’ ; so in1 has no current ( still don’t understand how it works internally ) . So 12v is flowing to illuminate the door bell and not through the sensor (????) When you press the door bell ; the 12v is now an open circuit the sensor becomes closed . erm - I’m confusing myself ? It works but I’m not confident I’m not sticking 12v into the sensor . Ran it for a few hours it didn’t get hot ?

Psu for the doorbell light psu for the universal sensor

There's no bell. Basically it's an illuminated push button. So it's lit ( supplied with 5v). . When you push it the light goes out. So I *assume* it makes an open circuit ( hence the light going out ). Not sure how the sensor works. Will draw up my wiring and see if that helps you ( or anyone else ) make sense of it !

Hmmm, I'm still a bit confused. I've set in1 as 'normally open' . But physically the 'input' isn't open is it?. Am I still sticking 12V through the sensor when I shouldn't be?? Can understand if it was a physically mechanical relay I could see it was open. Sensor isn't burning out yet!!. I guess I'm asking how are the input's 'opened' and 'closed' ???. It's not a real physical disconnection is it?

AHHHHHHHHHHHHHHH!!!! So that's how a DC illuminated doorbell works. Well I never! Can tell I'm a software engineer as this was definitely a hardware problem! ? Right illuminated doorbell works and triggers z wave sensor! Think I'll get my multi meter for door led ( just to convince myself ); also for automatic door unlock. But assume it's the same principle. I learnt something!!!

Thinking about the illuminated doorbell.... Maybe I power it; but stick the sensor on the gnd line and define it's initial state as 'closed' i.e. circuits complete so doorbell lights up. Then when the button is pushed the circuit is then open ( door bell not illuminated ) and then the sensor will detect it as 'open' ???

Ok ! I got this little fella working with my door bell button ( just a standard button ) So I get a z wave alert if the buttons pressed . What I don’t understand is my button is meant to be powered to light it up . How do I wire it so button is powered and lights up - but also only triggers a closed circuit ( no current ) for the fibaro sensor . ? Might not be possible. Though they sell an ‘implant’ but I can’t see much difference between that and this universal sensor . https://manuals.fibaro.com/binary-sensor/ https://www.fibaro.com/en/products/smart-implant/ It’s probably simpler than I think ! Have a similar issue with the front door built in led . Fed off a 12v transformer . Assume I wire live straight through then just use the sensor to close the circuit on the ground .

Yeah a basic 2 disk ( or even 1 disk ) system isn’t expensive. Grab one off eBay

Nas/nvr working really well ! Reconfigured 4 drives as shr-2 Cpu load hardly ever above 10% , ram use 7% 2 cameras recording at 6fps res 3000x2000 ( roughly ) . Set mobile stream to be a lot less obviously. Set home mode ; so when on-site I don’t trigger movement events . Had some issues with Catilina permissions ( who doesn’t ! ) . Now sorted so Mac squeezebox streams from nas MP3’s . Intend to add Mame Roms etc. to nas ( a little side project ) Currently trying to figure out how to use fibaro universal sensor ( my electronics / electrical skills limited ) Want doorbell to trigger z wave action Also want door integrated lights to be triggered by z wave . These little sensors confuse me as inputs seem to be dry ; so no current in . Erm - fiddling required .

Placed the nas on a crappy floating shelf . Think I’ll add extra brackets for support . nas/nvr working really well ! A few more connections to the router

I just bought a cheap staircase ; about £130

Oh no ! What have I done !!! ????

Bleeding cheek ! You can eat your food off that floor !

Fed up today , so swept the main floor . Does make the room seem bigger !!

And Adele did indeed sing with her Warm tones ...

I’ll finish that bit today and give Adele a proper workout

Sure I asked about this before. Everyone suggested plasterboard. Or do you mean specifically the speaker???

Is Adele heavy metal ???

Almost finished bathroom ceiling . Was worried ceiling speaker would be too heavy just to rest on plasterboard . So added a Marine ply base for it .

So I’m almost a professional plaster boarder !! ?

I was hoping someone would say that ! . I shall continue my rough work ??

Got some awkward cuts . Can I assume once the plasterer has finished swearing he’ll ‘get over’ my workmanship ?

I’ll have 2 please !
