The Topvico TP-819ZW 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 Topvico TP-819ZW 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

Water sensor powered by two AAA batteries, 1.5m probe cable.

### Inclusion Information

Click button inside housing for 0.5 seconds

### Exclusion Information

Click button inside housing for 0.5 seconds

### Wakeup Information

The Topvico TP-819ZW 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 Topvico TP-819ZW -:

| Channel | Channel Id | Category | Item Type |
|---------|------------|----------|-----------|
| Alarm (flood) | alarm_flood | Door | Switch | 
| Battery Level | battery-level | Battery | Number |

### Alarm (flood)

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 |

### 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 device has no configuration parameters defined.

## 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 Topvico TP-819ZW supports 1 association group.

### Group 1: Lifeline

The Lifeline association group reports device status to a hub and is not designed to control other devices directly. When using the Lineline group with a hub, in most cases, only the lifeline group will need to be configured and normally the hub will perform this automatically during the device initialisation.

Association group 1 supports 5 nodes.
