For SmartHome-Skills & German language, there has IMHO been no progress within the last 6 months. Undocumented non-support for certain languages e.g. for scheduling with ThermostatController is a No-Go. My preferred shortlist for german language support expansion: 1) Scheduling, 2) Sensors (Liters, Watt, kWh, mm etc.) to query all kind of numbers.
