The opentherm_gw climate platform is used to control the OpenTherm Gateway from Home Assistant.
{% linkable_title Configuration %}
# Example configuration.yaml entry
climate:
- platform: opentherm_gw
device: /dev/ttyUSB0
{% configuration %}
device:
description: "Path to OpenTherm Gateway device as supported by PySerial."
required: true
type: string
name:
description: The name for the device within Home Assistant.
required: false
type: string
default: OpenTherm Gateway
precision:
description: "The desired precision for this device. Can be used to match your actual thermostat's precision. Supported values are 0.1, 0.5 and 1.0."
required: false
type: float
default: "0.5 for Celsius and 1.0 for Fahrenheit."
floor_temperature:
description: Some thermostats round all temperatures down to the lower value according to their precision. Default behaviour for Home Assistant is to round temperatures to the nearest value. Set this to True to override Home Assistant and round to the lower value according to the configured precision.
required: false
type: boolean
{% endconfiguration %}
The OpenTherm protocol is based on polling. The thermostat sends requests to the boiler at specific intervals. As a result, it may take some time for changes to propagate between Home Assistant and the thermostat.
