MT02755 Humidity Sensor
This describes the Z-Wave device MT02755, manufactured by Devolo with the thing type UID of devolo_mt2755_00_000.
The device is in the category of Door, defining Door sensors.
The MT02755 supports routing. This allows the device to communicate using other routing enabled devices as intermediate routers. This device is unable to participate in the routing of data from other devices.
The MT02755 does not permanently listen for messages sent from the controller - it will periodically wake up automatically to check if the controller has messages to send, but will sleep most of the time to conserve battery life. Refer to the Wakeup Information section below for further information.
Overview
The multisensor MT02755 has temperature and humidity function in one, based on Z-WaveTM technology.
Inclusion Information
There are one tamper keys in the back side of the device, It can add, remove, reset or association from the Z-WaveTM network.
In the first time, add the device into the Z-WaveTM network. First, make sure the primary controller is in the add mode. And then power on the device, just take out the insulation Mylar in the back side of the device. The device will auto start the NWI (Network Wide Inclusion) mode. And it should be included in 5 seconds. You will see the LED light ON one second.
- Have Z-WaveTM Controller entered inclusion mode.
- Pressing the tamper key three times within 1.5 seconds to enter the inclusion mode.
- After add successful, the device will wake to receive the setting command from Z-WaveTM Controller about 20 seconds.
Exclusion Information
Exclude/Remove:
- Have Z-WaveTM Controller entered exclusion mode.
- Pressing tamper key three times within 1.5 seconds to enter the exclusion mode. Node ID has been excluded.
Reset:
Notice: Use this procedure only in the event that the primary controller is lost or otherwise inoperable.
-
Pressing tamper key four times within 1.5 seconds and do not release the tamper key in the 4th pressed, and the LED will light ON.
-
After 3 seconds the LED will turn OFF, after that within 2 seconds, release the tamper key. If successful, the LED will light ON one second. Otherwise, the LED will flash once.
-
IDs are excluded and all settings will reset to factory default.
Wakeup Information
The MT02755 does not permanently listen for messages sent from the controller - it will periodically wake up automatically to check if the controller has messages to send, but will sleep most of the time to conserve battery life. The wakeup period can be configured in the user interface - it is advisable not to make this too short as it will impact battery life - a reasonable compromise is 1 hour.
The wakeup period does not impact the devices ability to report events or sensor data. The device can be manually woken with a button press on the device as described below - note that triggering a device to send an event is not the same as a wakeup notification, and this will not allow the controller to communicate with the device.
Press the tamper button on the back side

Wakeup Interval
The wakeup interval sets the period at which the device will listen for messages from the controller. This is required for battery devices that sleep most of the time in order to conserve battery life. The device will wake up at this interval and send a message to the controller to tell it that it can accept messages - after a few seconds, it will go back to sleep if there is no further communications.
This setting is defined in seconds. It is advisable not to set this interval too short or it could impact battery life. A period of 1 hour (3600 seconds) is suitable in most instances.
Note that this setting does not affect the devices ability to send sensor data, or notification events.
This parameter has the configuration ID wakeup_interval and is of type INTEGER.
Wakeup Node
When sleeping devices wake up, they send a notification to a listening device. Normally, this device is the network controller, and normally the controller will set this automatically to its own address. In the event that the network contains multiple controllers, it may be necessary to configure this to a node that is not the main controller. This is an advanced setting and should not be changed without a full understanding of the impact.
This parameter has the configuration ID wakeup_node and is of type INTEGER.
Association Groups
Association groups allow the device to send unsolicited reports to the controller, or other devices in the network. Using association groups can allow you to eliminate polling, providing instant feedback of a device state change without unnecessary network traffic.
The MT02755 supports 1 association group.
Group 1: Receiving Report Message
Group 1 is for receiving the report message, like triggered event, temperature, humidity
Association group 1 supports 8 nodes.
