# Drayton Wiser Binding

This binding integrates the Drayton Wiser Smart Heating System (opens new window). The integration happens through the HeatHub, which acts as an IP gateway to the ZigBee devices (thermostats and TRVs).

# Supported Things

The Drayton Wiser binding supports the following things:

Bridge	Label	Description
`heathub`	HeatHub	The network device in the controller that allows us to interact with the other devices in the system

Thing	Label	Description
`boiler-controller`	Boiler Controller	The HeatHub attached to the boiler. This also acts as the hub device
`room`	Room Name	Virtual groups of Room Thermostats and TRVs that can have temperatures and humidities
`roomstat`	Thermostat	Wireless thermostats which monitor temperature and humidity, and call for heat
`itrv`	iTRV	Wireless TRVs that monitor temperature, alter the radiator valve state and call for heat
`hotwater`	Hot Water	Virtual thing to manage hot water states
`smart-plug`	Smart Plug	Wireless plug sockets which can be remotely switched

# Discovery

The HeatHub can be discovered automatically via mDNS, however the secret cannot be determined automatically. Once the secret has been configured, all other devices can be discovered by triggering device discovery again.

# Thing Configuration

# HeatHub Configuration

Once discovered, the HeatHub secret needs to be configured. There are a few ways to obtain this, assuming you have already configured the system using the Wiser App.

Temporarily install a packet sniffing tool on your mobile device. Every request made includes the secret in the header.
Enable setup mode on the HeatHub. Connect a machine temporarily to the WiserHeat_XXXXX network and browse to http://192.168.8.1/secret to obtain the secret.

The refresh interval defines in seconds, how often the binding will poll the controller for updates.

The awaySetPoint defines the temperature in degrees Celsius that will be sent to the heathub when away mode is activated.
