[RELEASE] Monoprice Door Window Mailbox Z-Wave Plus Sensor (Recessed/Mounted - 15268/15270/24259) with External Trigger Option and Tamper Device Handler (Official)

Works great!! Thanks.

Is there a way to latch the signal in ST for a few seconds so that I can use the signal for an Alexa routine? The momentary switch it’s connected to isn’t depressed long enough for Alexa to see the state change. I appreciate any help with this!!

Official Monoprice Door/Window Sensor Device Type - Version 02.01.04

  • Update for new ST app release causing contact sensor to not be displayed for some users

To force ST to use the updated UI after updating/publishing the DTH:

  • My Devices -> Click on monoprice door sensor device -> Scroll down and click on Edit -> Scroll down and click on Update
  • Force kill and restart ST app

The new ST app is still experimental so it’s recommended to continue using the ST Classic app to get access to all the features of the DTH

I removed an old alarm system and wanted to reuse- my wired basement magnetic window switches that are already installed, but with my Smartthings set up. The monoprice door/window sensor with the 2 screw terminals was exactly what I was looking for. The default smartthings device handler does not support the terminals (as reported in this thread- very helpful). I tried another device handler out there (not the RBOY one) - that was supposed to work and it did not work for me and I tried. I finally tried the RBOY one (requiring a fee to get my login to download)- and it does work - well. The RBOY instructions referenced above are very good and actually helpful. Thank you for those- nice product. You have to keep the magnet attached to the switch- that is counter intuitive to me- but that is mentioned in a couple places. So many possibilities to make unique sensors and to utilize existing wired sensors in old houses (where the wires are run). It is a shame its not easier and that no one makes a native smartthings sensor with two screw terminals for an external contact sensor !

This one works with the native SmartThings device handler, executes locally.

THANK YOU ! I should have purchase this one. next time !

I’m going to ask a stupid question here, but why would I want to use this device handler over what appears to be built into ST? I have 4 of the Monoprice recessed sensors and they seem to work pretty good. They aren’t 100% effective and are slow sometimes, but work decently.

Is that something that gets fixed when using this device handler?

Just to follow up, it looks like there isn’t a reason to use this device handler?

Hey there. Sorry for the delay. This device handler gives you access to devices advanced settings to allow you to customize its behavior, usage and also provides workarounds for quirks/issues in the firmware. Some devices can be used with internal or external triggering which can be configured using this device handler.

You can find more details in the first post.

No problem. That was the reason for the bump. I figured it got lost in the shuffle.

Would this resolve the issue of the sensors reacting slow sometimes? One time it’s almost instantaneous and the next time it takes 5 seconds. I’ll buy it right now if it does. :smiley:

It sounds like your device is having connectivity or mesh trouble. There could be many reasons for this but usually adding a repeater within 15ft if the device helps make communications more reliable and predictable. See this topic for details, it refers to locks but applies to other devices as well: FAQ: why would I need another beaming repeater if my zwave lock is already close to my hub?

Thanks for the help, but I don’t think that’s the case. I have 37 wired devices and 6 wireless. There are 11 Zwave+ GE dimmers in the basement, and each of the basement wireless door sensors are about 3’ from their dimmer. I’m pretty sure that the GE dimmers are repeaters, so each wireless sensor is right next to a repeater.

An example of what the 24259 mailbox sensor looks like in action:

It has a tamper sensor built in so if anyone tries to remove/tamper with it, it’ll send a Tamper notification to ST which can be processed with a compatible SmartApp like this one to notify you or trigger a siren: [RELEASE] Security System: Intruder Alert with Actions - Entry Delay, Exit Delay, Countdowns, Keypads, Lights, Alarms, Pictures/Cameras, Routines

Any idea what the range is on this?

Depends on the setup but ideal conditions you can get up to 300ft or more. By design it says 500+ft but in practice expect between 50to 300ft depending on your setup, ie. mailbox construction (plastic, metal, brick), trees, landscaping objects etc. In our setup we have it at about 75ft from the building in the mailbox (open to the elements) and it’s been good for about 2 years now.
Do note that it always helps to keep a mains powered Z-Wave Plus device (repeater) connected to an outlet (GFCI) on the outside of the house, in the closest spot/direction of the mailbox and that helps a lots. Without the repeater device the range may drop significantly depending on how many walls/obstructions the signal needs to get through.
