Best Sensors for sliding doors ?

I’ve just had some wardrobes fitting with 3 sliding doors and wanted to reach out to see if anyone has done a similar project.

The plan is simple, operate some Hue lights inside the wardrobe when any door is opened. The 3 doors slide close to each other so it looks like I’ll need a sensor on each end door and then to come up with something “creative” for the middle door (if there was space it would of been easier just to put 2 sensors on either end of the middle door to cover any door movement).

So far I’m thinking Fibaro door / Window sensors might be the best option, they work well with Vera and will fit the bill but is there anything else better out there ?.

If only there was a zwave break beam sensor! (might be to ambitious to make one for a 1st Rasp PI project).

All I can offer is that the Fibaro sensors work well. I’ve been running them on my windows for 6 months now without a single hiccup. They cost more than others but everything I’ve read has pointed to them being the best.

Thanks. I’ve also got a number of them on windows and would agree they work very well hence why I thought they might be the best sensor for this project to.

All you need is some normally open(NO) alarm magnets such as these Surface Mount Magnetic Contacts and a single Fibaro FGK-101 Door/Window Sensor or a Schlage RS100 Door/Window Sensor

Wire the three magnets in series and connect them to the door/window sensor and you’re golden.

This works well, I’ve had a bank of 4 windows monitored by one Fibaro sensor. Order some contacts off Ebay and it’s certainly cheaper. You need to know how to solder but it’s a pretty easy project. I have my wires hidden with some white conduit stuff they sell to hide stereo/telephone wires on walls. It has an adhesive foam on one side and it sticks to wood pretty well.

Agree that using standard door sensors into a fibaro is the best way to go for this, but I just wanted to add that you can put together a beam break sensor Vera can recognize pretty easily using the same strategy. Just buy the seco alarm beam break sensor and wire into the same Vera door/window sensor.

Excellent thank you that makes perfect sense. I’ll get some sensors and give it a go. This will also be useful for a bank of Windows I’ve got on my conservatory.

@Z-waver, Shouldn’t those switches be normally closed if in series?

Think about it @gregl. The switches will be open (normally open) when not affected by the magnet and be closed when the magnet is close to them.

[quote=“gregl, post:8, topic:189909”]@Z-waver, Shouldn’t those switches be normally closed if in series?[/quote]Normally open switches are open when the magnet is removed and closed when the magnet is in place. With normally open switches, when all the magnets are in place, you have a completed circuit. A continuous loop of wire, if you will. If any one of the magnets are removed, the switch opens and the circuit is broken - Z-Wave event.

Doh…yes of course…I forgot about the actual door positions…
