RBoy Apps is now an official partner of Monoprice.
This Device Handler is for the Monoprice 4 in 1 Motion Sensor with Temperature, Humidity and Light Sensor (15902).
This passive infrared (PIR) sensor detects motion and sends a Z-Wave® trigger signal to the network. It also features temperature, humidity, and light sensors, which will automatically report changes in the conditions and will report the absolute values when queried. It has a tamper-proof switch, which will trigger a Z-Wave signal when the cover is removed.
This device handler supports the Z-Wave and Z-Wave Plus devices. Support has also been added for v1 and v2 hub fingerprinting for easy identification and supports the Classic and new ST app. Ideally install the Device Handler BEFORE pairing the device for easy setup.
The device can be bought directly from Monoprice here for about $29 - $34 (depending on the sale)

This device handler supports the following features:
- Reading the following sensors
- Ability to select the primary sensor to show in the ‘Things’ page (Temperature, Motion, Humidity or Light)
- Ability to configure the following parameters:
- Motion timeout
- Temperature sensitivity
- Temperature correction (offset)
- Motion sensitivity
- Light sensitivity
- Humidity sensitivity
- LED configuration
- It automatically sets the temperature units (F/C) on the device based on your hub location
- Option to choose been reporting light as
- Support for v1 and v2 hub fingerprinting for easy identification
- Ability to request a manual update for the sensors and configuration (this is a delayed update at the next wake up)
- Easy to use configuration page with detailed explanations for all the parameters
- Reporting device tampering to SmartThings (as a tamper device capability)
Ideally install the Device Handler BEFORE pairing the device for easy setup.
- After the configuration/preferences are updated, for the settings to take effect immediate, press the Z-Wave button with a pin (tiny hole at the bottom of of the sensor)
- To request the manual update, please press the “Request Update” button, however this is a DELAYED update. The motion sensor is mostly in sleep mode to preserve battery. The next time it wakes up (every 4 hours or as configured), if the user had requested a manual update, it will fetch the latest sensor status, battery and also update the configuration.
- To force an immediate update for all configured settings, press the “Request Update” button and then press the Z-Wave button with a pin (tiny hole at the bottom of of the sensor). This forces the motion sensor to wake up and process the manual update request.
- To force a sensor/battery status update just press the Z-Wave button with a pin (tiny hole at the bottom of of the sensor)
Optimizing Battery Life
- These units use alkaline batteries by default and which tend to have a lower voltage than Lithium batteries hence the battery % tends to drop faster initially. It’s normal for the battery to go from 100% to 90% in a day due to the voltage discharge curve of alkaline batteries. These units function all the way down to 15% or lower. Overall battery life from 100% to 15% should be between 3-9 months with standard Alkaline batteries. Rechargeable batteries should not be used as the voltage isn’t high enough and the voltage curve drops very quickly. Best would be to use 1.5v Lithium batteries (non rechargeable) which can double or triple the life before you need to replace batteries and provide a more stable voltage discharge curves.
- Whether the life is 3 or 9 months depends up on your settings and usage. If you set the sensitivity of humidity, temperature, motion and light very high the battery will drain quickly because you’re essentially asking the sensor to pretty much continuously send updates. What I would recommend is to identify how sensitive do you need each sensor and then set the sensitivity accordingly. E.g. For Humidity you want to know if there a 5% or 10% change, where as for light you only care about dark or light so set that at 50%, for temperature you don’t care so set it to the least sensitive, for motion similarly set the timeout and sensitivity. Optimizing this can make a HUGE difference in your battery life
- Finally set the LED mode to Off or Quick Flash setting. Avoid using the Breathing mode as it’ll drain your battery
Low Battery: If your battery below 20% consider replacing it. The device may stop sending updates if the battery falls below this level. So you won’t know if you battery has run out, the motion/no motion sensors / temperature sensor may get stuck as well and you may receive no updates.
More features to added, if you have any suggestions or ideas please feel free to ask and we’ll try to add it.
INCLUSION INSTRUCTIONS: It is recommended to install the Device Handler BEFORE paring the device for easier setup.
- If you are unsure about the device state exclude the device first otherwise it won’t pair (see below)
- To pair the device, Select Add New Device from the MarketPlace on your ST phone app.
- Then press and release the Z-Wave button with a pin (tiny hole at the bottom of of the sensor) TWICE quickly
- It should complete pairing within 30 seconds
EXCLUSION INSTRUCTIONS: If you deleted the device without excluding it won’t pair up again until you exclude it.
- Set the hub into exclude mode (log into the IDE -> My Hub -> View Utilities -> Z-Wave Exclude.
- Press and release the Z-Wave button with a pin (tiny hole at the bottom of of the sensor) TWICE quickly
FACTORY RESET: Remove the cover and press and release the Z-Wave button with a pin (tiny hole at the bottom of of the sensor) 10 times within 10 seconds.
You can find the installation/update instructions here
Here are some SmartApps that can be used with the sensor to manage humidity and temperature
