Set Hostname

Each device is given a unique hostname by the factory. When using multiple thermostats, each device must have a unique name so that the devices can be distinguished from each other. Furthermore, the assigned hostname is used as an upstream prefix when sending MQTT messages in the payload. For clear differentiation and better readability, it is recommended, for example, to specify the room. The use of umlauts and special characters should be avoided.

Enter MQTT credentials

To exchange data between the thermostat and the MQTT Broker of the smart home system, the corresponding access data of the MQTT Broker must be stored in the MQTT Client page. Without providing a URL of the SSL certificate, the data exchange takes place in unencrypted form. When connecting to an MQTT broker outside the local network, the use of an SSL certificate is highly recommended. When connecting locally to an e.g. MQTT broker in HomeAssistant within the home network, the SSL certificate is negligible, as the router has a firewall for
