--- layout: documentation title: MT2756 - ZWave --- {% include base.html %} # MT2756 MT2756 Flood Sensor This describes the Z-Wave device *MT2756*, manufactured by *Devolo* with the thing type UID of ```devolo_mt2756_00_000```. The device is in the category of *Sensor*, defining Device used to measure something. ![MT2756 product image](https://www.cd-jackson.com/zwave_device_uploads/489/489_default.jpg) The MT2756 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 MT2756 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 Home Control Water Sensor is a water sensor and warns you about flooding or leaking water. As soon as water touches the open metal contacts, the device triggers an alarm. The Home Control Water Sensor is ideal for use in locations such as under a sink, under the supply valve of a washing machine or on an aquarium. It is equipped with an integrated LED and a release button. ### Wakeup Information The MT2756 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. ## Channels The following table summarises the channels available for the MT2756 -: | Channel | Channel Id | Category | Item Type | |---------|------------|----------|-----------| | Binary Sensor | sensor_binary | Door | Switch | | Alarm (water) | alarm_flood | Door | Switch | | Alarm (burglar) | alarm_burglar | Door | Switch | | Battery Level | battery-level | Battery | Number | ### Binary Sensor Indicates if a sensor has triggered. The ```sensor_binary``` channel supports the ```Switch``` item and is in the ```Door``` category. This is a read only channel so will only be updated following state changes from the device. The following state translation is provided for this channel to the ```Switch``` item type -: | Value | Label | |-------|-----------| | ON | Triggered | | OFF | Untriggered | ### Alarm (water) Indicates if the flood alarm is triggered. The ```alarm_flood``` channel supports the ```Switch``` item and is in the ```Door``` category. This is a read only channel so will only be updated following state changes from the device. The following state translation is provided for this channel to the ```Switch``` item type -: | Value | Label | |-------|-----------| | OFF | OK | | ON | Alarm | ### Alarm (burglar) Indicates if the burglar alarm is triggered. The ```alarm_burglar``` channel supports the ```Switch``` item and is in the ```Door``` category. This is a read only channel so will only be updated following state changes from the device. The following state translation is provided for this channel to the ```Switch``` item type -: | Value | Label | |-------|-----------| | OFF | OK | | ON | Alarm | ### Battery Level Represents the battery level as a percentage (0-100%). Bindings for things supporting battery level in a different format (e.g. 4 levels) should convert to a percentage to provide a consistent battery level reading. The ```battery-level``` channel supports the ```Number``` item and is in the ```Battery``` category. ## Device Configuration The following table provides a summary of the 7 configuration parameters available in the MT2756. Detailed information on each parameter can be found in the sections below. | Param | Name | Description | |-------|-------|-------------| | 1 | Basic Set OFF Level | Setting the BASIC command value * When the flood trigger off(0x00), send the BASIC CC to the group 2 | | 2 | Basic Set ON Level | Setting the BASIC command value * When the flood trigger on(0xFF), send the BASIC CC to the group 2 | | 5 | Disable the Flood function | Operation mode * 0: Flood function is enabled * 1: Flood function is disabled | | 7 | Customer Function | Parameter to set the sensor functionsBit 0: ReserveBit 1: ReserveBit 2: ReserveBit 3: Disable send out BASIC OFF after the flood event clearedBit 4: Notification Type. 0:Using Notification Report, 1:Using Sensor Binary ReportBit 5: Disable Multi CC in aut | | 10 | Auto Report Battery Time | The interval time for auto reporting the battery level * 0 = Turn off auto report battery. * 1-127 = Number of ticks.
