Lo scopo di questa app è quello di consentire la configurazione del dispositivo MyOT/MyMB al momento in cui viene installato sulla caldaia/pompa di calore/inverter e molti altri dispositivi. Risulta possibile indicare il server di controllo a cui collegarlo e i riferimenti al Wi-Fi di casa necessari al suo controllo remoto (ad es. per l'aggiornamento del firmware di bordo). In aggiunta è possibile visualizzare una lista di tutti i dispositivi MyOT/MyMB censiti, i propri dati anagrafici ed i messaggi che questo dispositivo genera e trasmette verso il centro.
