How is the pressure mat powered?

You need to use a contact sensor that has connections for an external input such as the GoControl Door/Window sensor and a modified DH mentioned in this thread.

@Jimxenus
So, are you saying that these pressure mats are basically just a simple switch that needs no power other than being connected to the terminals on the open/close sensor?

[Jimxenus]

That’s right, the pads are merely a switch that closes when you step on them. The GoControl has a battery of course and senses the swtch when closed.

Nice. Can’t get any more simple than that.

[patrickgeiger]

Sweet. Thanks for the info!

My mat…

Someone do a youtube video of the installation!!

[blinduvula]

Sorry for the dumb question, but how do you add the icon?

[Jimxenus]

@blinduvula

how do you add the icon?

First, you should be using the custom Device Handler found at post 22 in this thread

United security pressure mat

I wrote a custom device call pressure mat that is the same as the door device but with new icon and message for stepped on and empty. Then I wrote a smart app that does something when stepped on, which is reverse logic from the existing built in open door app. I then took a picture of my mat and used it to override the icon so it looks like a mat. The device code is: /** * Z-Wave Pressure Mat Sensor * * Author: SmartThings - edited by KW * Date: 2013-11-3 */ // for the UI metadata { // Automatically generated. Make future change here. definition (name: "Z-Wave Pressure Mat Sensor", namespace: "kewashi", author: "Ken Washington") { capability "Contact Sensor" capability "Sensor" capability "Battery" capability "Configuration" fingerprint deviceId: "0x2001", inCluster…

[OBSOLETE] FAQ: An Overview of Using Custom Code in SmartThings (SmartThings Classic, Groovy Code)

The original FAQ information in this thread refers to the original smartthings architecture, which was in place through the end of 2022 and a little beyond. Custom code was written in the groovy programming language and ran in the smartthings cloud. As of May 2023, you can no longer add new Groovy DTH‘s or smartapps to your smartthings account. So if you came here because of a link in an old forum thread, or on another site, I’m afraid the Groovy information is no longer usable. All of this was replaced by a new architecture. Cloud to cloud integrations use the smartthings API. Hub connected devices, mostly Zigbee and zwave, now use “Edge Drivers,” written in the LUA programming language. Here’s the official announcement on those: The process for using a custom Edge Driver in the new …

Download my icon (or use one of your own) and transfer it to your photo library of your phone.

For anyone interested, I created an icon that better matches the ones that SmartThings uses. It has a transparent background so the colors and text still show up. [image]

In the device handler on your SmartThings app, click on the gear icon in the top right corner. Then simply click on the “Set Device Image” link to browse for your icon.

Thanks! DTH and icon all set up and looking great. Thanks x2 for your time and effort!

I’ve bought the mat, but before I buy the Ecolink door sensor, does anyone have experience using the Iris 3320-L Contact Sensor? I have a few available. I ask because they look impenetrable without breaking it.

[Jimxenus]

You’ll need a contact with external connections. The Iris do not have them.

[JMZ]

Just thought you all might be interested, I changed the code to flip the open/closed status of the sensor so that new closed is normal, unstepped-on state, and open is the stepped on state. (It also uses my modified icon, red feet when stepped on, white otherwise). I did this because most SmartApps out there considered ‘open’ to be the ‘bad’ state of a contact sensor (e.g. door open). It doesn’t effect how the sensor works or displays (all that was updated as well), but if you use smarttiles it highlights stepped on now instead of vice versa, and if you use any smartapps that only trigger things when contacts open, this work appropriately without any extra effort.

Thanks for improving upon my idea. This is what makes the ST community so great.

Just came across this project report over at instructables for a mattress pad based on the same concept:

In-Bed Presence Detector (SmartThings + Z-wave Pressure Mat)

[jgirvine]

Ahhhhhh, thanks

[GGexe (Eddy)]

Amazing find.
Any cheap alternative to the Ecolink DWZWAVE2-ECO? its $40+ in canada

I think the ecolink is typically the cheapest. The Aeotec Dry contact and the Fibaro both cost more.

how does everyone deal with the weather. Are these items weather proof?

@jfattizzi

how does everyone deal with the weather. Are these items weather proof?

As far as pressure mats themselves go, it depends on brand and model, but definitely many are intended for outdoor use, including the United security one discussed in most of the projects in this thread. For example, the small mat is often sold for use as a “doorbell” for warehouses or RVs or even boats at a marina.

You run wires from the mat to whatever radio device you’re going to use. So it’s often very easy to put the radio device in a sheltered location or even indoors and just run wires to the mat.

If you going to put the radio device outdoors as well, then all of the usual caveats apply.
