Sonnen Batterie

Adds support for Sonnen Batterie - Time of Use (ToU) and more. The sonnenBatterie does not only store energy, it's smart. As an intelligent, backup capable, energy storage system, sonnenBatterie 10 can integrate into any existing PV system on the market. Gain your energy independence now and secure yourself against future energy price increases. This app allows you to set or reset Time-Of-Use, change the operating mode and enable/disable forecast/prognosis charging. This is very useful with changing energy prices, you can pause your batterie delivery on low tariff or charge batterie on low tariff - so being fully charged in times with high tariff. The battery's backup buffer (EM_USOC) - the state of charge the battery will not discharge below during normal operation - can be monitored on the device, changed in the device settings and automated from flows. Reset Time-Of-Use is very useful, because once schedule is set - the schedule is repeated daily. Reset will clear the schedule. Please use this before setting a new schedule. Be aware, currently only one schedule/Time-Of-Use is supported to be set by a flow. However the device settings dialog already allows to set multiple events. Be sure to enable the ToU operating mode to be effective. Note that changes to the ToU schedule, prognosis charging and operating mode are only possible if the Sonnen write API is enabled. Usage notes: Be sure to create at least a "sonnenBatterie" home battery device. This device is mandatory to provide data to all other derived devices such as "household", "grid" and "solar panel". The derived devices offer nicely grouped capabilities, convenient insights and dedicated status indicators. Also you can associate your solar panel with your home's roof zone, your grid device and home battery with cellar or whatever zone fits. Instead of using this app's derived devices also dedicated apps providing smart meter or solar panel/inverter devices can be used. However when having multiple devices providing the same type of data, be sure to exclude all but one from Energy tab by using the device's "Exclude from Energy" setting. Also consider excluding the household device from Energy. Please visit the application's settings page, after installing this application. Configuration fields are mandatory.
