STIEBEL ELTRON	Instructions on how to integrate STIEBEL ELTRON integral ventilation and heat pump units into Home Assistant.	Climate	0.92	Local Polling	@fucm	stiebel_eltron	climate	integration

The stiebel_eltron integration lets you control integral ventilation or heat pump units of STIEBEL ELTRON.

It requires the following components:

• Compatible STIEBEL ELTRON unit (see "Compatibility overview" in Software Documentation Modbus TCP/IP)
• ISG web, with the Modbus module enabled
• IP network connection to the ISG web

Supported units

By now, the following units are tested:

• LWZ 504e
• LWZ 304
• LWZ 304 Trend

HVAC modes

The following HVAC modes are supported. The STIEBEL ELTRON modes are mapped and configurable as follows:

• Auto (HVAC_MODE_AUTO): Automatic mode
• Manual (HVAC_MODE_HEAT): Manual mode
• Off (HVAC_MODE_OFF): DHW mode (domestic hot water mode, heating is switched off)

Preset modes

The following preset modes are supported. The STIEBEL ELTRON modes are mapped and configurable as follows:

• Eco mode (PRESET_ECO)
• Day mode (PRESET_DAY)
• Setback mode (PRESET_SETBACK)
• Emergency mode (PRESET_EMERGENCY)

Configuration

To enable this component, add the following lines to your configuration.yaml file:

# Example configuration.yaml entry
stiebel_eltron:
  name: LWZ504e

{% configuration %} name: description: Displayed name of the unit. required: false default: Unnamed Device type: string hub: description: The name of the hub where this slave is located. required: false default: default type: string {% endconfiguration %}

This integration requires the Modbus integration to be set up to work

Full configuration example including modbus setup shown below:

# Full example configuration.yaml entry
modbus:
  type: tcp
  host: YOUR_ISGWEB_IP
  port: 502
