+      OneKey-Heizungsregelung mit aktivierter evcc-Anbindung. Die Wärmepumpe
+      wird über SG-Ready-Zustände geführt (1=Dimmen, 2=Normal, 3=Boost).
+      Dazu muss im OneKey-Gerät der Energiemanager im Modus SG-Ready laufen
+      und evcc als SG-Ready-Quelle eingestellt sein. Läuft evcc auf dem
+      OneKey-Gerät selbst, ist der Broker `localhost`.

+      OneKey heating controller with evcc integration enabled. The heat pump
+      is controlled via SG Ready states (1=dim, 2=normal, 3=boost). The
+      device's energy manager must run in SG Ready mode with evcc selected
+      as the SG Ready source. When evcc runs on the OneKey device itself the
+      broker is `localhost`.
