# OpenTherm Gateway Binding
This binding is used to integrate the OpenTherm Gateway into openHAB. The OpenTherm Gateway is a module designed by Schelte Bron that can be connected to units that support communication using the OpenTherm protocol, such as boiler or ventilation / heat recovery unit.
More information on the OpenTherm Gateway device can be found at https://otgw.tclcode.com/ (opens new window)
# Discovery
The binding does not support auto discovery.
# Binding Configuration
The binding does not require any configuration.
# Supported Things
The OpenTherm Gateway binding supports three Things:
openthermgatewaywhich is the bridge that handles communication with the OpenTherm Gateway device.boilerwhich represents a central heating boiler unit.ventilationheatrecoverywhich represents a ventilation / heat recovery unit.
# Thing Configuration
# Thing Configuration for openthermgateway
The openthermgateway bridge is designed to support various ways of connecting to the OpenTherm Gateway device, but currently only supports a TCP socket connection.
The configuration settings for the bridge are Hostname/IP address and Port, which are used to connect to the gateway, and an automatic connection retry interval in case the connection to the OpenTherm Gateway device is lost.
| Parameter | Name | Description | Required | Default |
|---|---|---|---|---|
ipaddress | Hostname or IP address | The hostname or IP address to connect to the OpenTherm Gateway. | yes | |
port | Port | The port used to connect to the OpenTherm Gateway. | yes | |
connectionRetryInterval | Connection Retry Interval | The interval in seconds to retry connecting (0 = disabled). | yes | 60 |
connectTimeoutSeconds | Connect Timeout | The maximum time (seconds) to wait for establishing a connection to the gateway. | yes | 5 |
readTimeoutSeconds | Read Timeout | The maximum time (seconds) to wait for reading responses from the gateway. | yes | 20 |
# Thing Configuration for boiler and ventilationheatrecovery
The boiler and ventilationheatrecovery things do not require any configuration settings.

# Transparent Slave Parameters and Fault History Buffer channels
The transparent slave parameters (TSP) and fault history buffer (FHB) use a variable number of entries. The number of entries is determined by a TSP or FHB size message. Channels for TSP and FHB entries are automatically created when a TSP or FHB size message is received. An index number is added to the base channel name to create a unique channel name for each entry.
For example, if a TSP size message is received for a boiler unit (OpenTherm DATA-ID 10) with value 60, then channels tspentry_0 through tspentry_59 will be automatically created and linked to the corresponding TSP entry (OpenTherm DATA-ID 11).
# Using OpenTherm Gateway as a master device
When using OpenTherm with a boiler and a thermostat, the thermostat (master) periodically sends messages to the boiler to request data. The boiler (slave) then sends a response message with the requested data which is then used by the OpenTherm Gateway binding to update the channel values in openHAB.
If you have a setup without a master device requesting data, then the slave device may send fewer or even no OpenTherm mesages at all.
In this case, you can make the OpenTherm Gateway act as a master device by sending Priority Message (PM) commands.
With openHAB rules, you can use the sendcommand channel of the openthermgateway bridge to periodically send PM commands to the OpenTherm Gateway.
Example:
SendCommand.sendCommand("PM=10")
This will cause the OpenTherm Gateway to send a READ-DATA message to the slave device with DATA-ID 10. If supported, the slave device will respond with a READ-ACK message and the current value.

# Migration from Prior Versions of the Binding
Between openHAB v3.2 and v3.3 the structure of Things and Channels was changed. This means that Things and their respective Channels and Items that were created on v3.2 or earlier will no longer function on version v3.3 or later. To be specific the change is as follows..
openHAB Versions v3.2 or earlier: There was just one single
otgwThing that combined the functions that communicate with the OpenTherm Gateway together with the functions of the Channels that monitor/control the connected Boiler.openHAB Versions v3.3 or later: The communication functions have been moved to a new
openthermgatewayBridge Thing. The connected Boiler functions have been moved to a newboilerThing. And in addition (if needed) new functions for a connected Ventilation / Heat-Recovery system have been added in a newventilationheatrecoveryThing.
So if you upgrade your system from openHAB v3.2 (or lower) to v3.3 (or higher), then your Thing and Item definitions must be migrated as shown below..
Divide the contents of your old
openthermgateway:otgw:yourGatewayIdThing definition into two new parts, namely 1) a newopenthermgateway:openthermgateway:yourGatewayIdBridge definition for the OpenTherm Gateway, and 2) a newopenthermgateway:boiler:yourGatewayId:yourBoilerIdThing definition for the connected Boiler.Change the
channel=".."configuration entries of all your Items from referring to the ThingUID of the oldotgwThing to refer instead to the ThingUID of the respective newly createdboilerThing.
# Old Thing Definition and respective Item Definition (example)
Thing openthermgateway:otgw:yourGatewayId [ ipaddress="192.168.1.100", port=8000, connectionRetryInterval=60 ]
e.g.
Number:Temperature Boiler_DHW_Temperature "Boiler DHW Temperature [%.1f %unit%]" <temperature> {channel="openthermgateway:otgw:yourGatewayId:dhwtemp"}
&c.
# New Thing Definition and respective and Item Definition (example)
Bridge openthermgateway:openthermgateway:yourGatewayId "OpenTherm Gateway" @ "Kitchen" [ipaddress="192.168.1.100", port=20108, connectionRetryInterval=60] {
Thing boiler remeha "Boiler" @ "Kitchen"
}
e.g.
Number:Temperature Boiler_DHW_Temperature "Boiler DHW Temperature [%.1f %unit%]" <temperature> {channel="openthermgateway:boiler:yourGatewayId:remeha:dhwtemp"}
&c.
