Outdoor Z-wave Sensor for a Gate

I followed the directions to get the Contact sensor to work. I don’t remember there being any issues, but that isn’t the case with every sensor. Sometimes when pairing multiple sensors of the same type some pair easy and some don’t. Sorry I don’t have a better answer. I would suggest factor resetting the sensor. It usually works.

Thanks for the quick reply. I followed your advice and it paired up. Working fine now.

Will this work for a doorbell?

When you paired it did you need to change the device type?

Can anyone update their experience with the Aeon hidden door sensor and dry contact sensor? I bought one of each for a wooden gate and metal gate in my back yard.

There appears to be a pretty substantial gap in the top of the hidden door sensor with the electronics right behind it. I’m concerned there will be a lot of issues with moisture in this device. Did anyone using this, cover the inside with seran wrap to prevent moisture getting inside?

Also, I live in New England and I’m thinking cold winters are going to be tough on the batteries on these devices. Any experience with this?

Thank you!

The Sensative Strip is a zwave plus sensor designed for outdoor conditions. Works well, is very slim so fits inside the gate frame. It’s also paintable. It’s from a Swedish company with a patent on their design.

Strips is designed to withstand normal outdoor climates. The mounted PCB is coated in a moisture protective film before it is placed and sealed in the plastic casing. All components are specified to work between -20 degrees Celsius (-4 F) up to + 60 degrees Celsius (140 F).

So that’s about as good as you can expect from a battery operated device, batteries just won’t work very well below freezing.

The main drawback is that they’re expensive, list price $60, but the smartest House does have an offer where they give you a free Zooz indoor motion sensor with each sensative strip, so that makes the cost much more reasonable:


If you need something that will operate in much colder temperatures, pretty much your only option is to use a conventional weatherproofed mag closure and run wires to a Z wave radio device which is in a more sheltered location. That’s what people have been describing up above such as in post 13. This should work fine, it’s just a little more work to set up and may not be quite as convenient.

As far as using saran wrap on any battery powered device – – don’t. Also don’t put it inside a Ziploc bag. Batteries outgas, and they need to be vented in order to do so to operate safely. You also have to be careful not to change the heat distribution on small battery powered devices or you can damage the internal parts.

There are some sealants you can buy for electrical parts, but they will void the warranty, they can be tricky to use, and again you don’t want to actually seal the battery area of the device.

The safest method for weatherproofing is to put the whole device inside a vented electrical projects box. Like the ones used around exterior Wall outlets. Don’t use metal, of course, because it will interfere with the signal, but plastic is usually OK.

I have used a recessed sensor for a long time (Wet North or England )

Recessed one on my back gate… drilled a couple of holes in the cover (in the bottom )
To make sure the air could get to it… no condensation

Samsung multisensor on a metal drive gate… in a project box… again with air holes

These have been working for a year or more… no problems yet


The gap in my outside gate is to large for most of the proposed solutions to work.
I can’t find the thread now, but someone in another thread recommended the below, and it’s working well for me!

Magnetic open/close sensor (gap up to 4inches):

Dry contact sensor (Takes input from the open/close sensor for ZWave):

As the Dry contact sensor isn’t rated for outdoor use, I put it in one of these:

I just had to drill a tiny hole in the box.to insert the wire, and sealed the hole with some sealant, like this:stuff:

End Result:

(Note: The while the box is sealed for outdoor use, the screws it comes with started turning orange within a few days, so I sealed them with sealant as well.


I bought 3 of the Sensative strip sensors. 2 of them work, albeit with a slight delay in notification of change in status. The 3rd one worked for a little while then stopped. I think I had it too low on the gate and it couldn’t communicate w/ the hub. The other 2 I had to play a bit with some plywood to get the gap at the right distance where it always worked. Pretty pleased with them so far.

I have been using these for over two years without an issue

We have a kit for both covered doors / gates and weatherproof kit for doors and gates that are exposed to the elements.

I have been looking for the same thing for a long time. Decided to go the “cowboy way” and bought this thing

sealed it with industrial aluminum tape and stuck it to my mailbox lid. So far so good. My logic behind this is that I will not cry my eyes out when something so cheap fails. We’ll see.

The sensor itself is clunky but very fast in reporting.

Does this relay give battery status updates to the hub?

i use this sensor and added a larger maget bar to the gate to make the difference…


I have a driveway gate about 100ft from the closes z-wave device, any suggestions? I’d like to have a sensor on it to show when opened/closed.


status update 4 months later - still working perfectly. Battery level after 4 months of really cold weather - 88%.

Could you share how you were able to get your Gen 5 to pair?

If you press and hold the “action button” on the Gen 5 for 20 seconds it will factory reset the device and remove it from the network. Remove the battery and set the SmartThings app to “add a thing” then re-insert the battery. Press the action button once on the Gen 5 and SmartThings should find it as a Z-Wave door/window sensor. If that doesn’t work you can try adding the device manually in the IDE using the Z-Wave door/window sensor as the type.

I have looked for the dry contact sensors to use as an open closed gate sensor with no luck. Maybe they have been removed.
But, I have an idea that I’m going try.
I have several of the door/ window open closed sensors that use the magnetic reed switches to sense the open closed status.
I’m going to remove the reed switch and add a set of contacts that can connect to a wired garage door open closed switch.
This should work the same as the dry contact sensor. I can mount the modified door sensor in a dry location and run the wires to the gate.
I’ll update this post with pictures and information as the project progresses.

So, I have a working remote gate sensor.
I purchased a cheap Neo Coolcam open/closed sensor off eBay for $17.50 free shipping.

My thought was to remove the reed switch and solder a connection block in its place.
As soon as I touched the connection to unsolder it the glass on the switch broke.
No big deal. I just used those wires to solder to the junction box.
I purchased a garage door open/closed reed switch for a wired alarm system from eBay for $12.17 free shipping. (No longer available, but here are a couple).

And 15 feet of micro flex conduit from a commercial supply store. It’s for running fiber optic cable.
Here is what it looks like.

(I will edit this with part number and cost).
But any kind of outdoor cable would work. I was worried about squirrels chewing on the cable is the reason I armored it.
I ran the cable through the same hole in the wall of the house used for my air conditioner and placed the modified open/close sensor inside the house.
The garage door switch mounts on one side of the gate and the magnet mounts on the other side. I used existing screw holes in the gate to mount the switch. The magnet had to be shimmed out a little but wasn’t difficult to find something to mount it. Home Depot sells some flat metal that is about 3ft long with holes above every inch in the plumbing department. Cost about $3.
Cut to length and screwed the magnet to it.
So for less than $40 I have a working gate monitor.
I’m going to create an instructable with better documentation and pictures.
I’ll post a link.
