Note on Monthly and Weekly Statistics
Important: The adapter automatically saves data from last month and last week in the states.
Monthly Statistics
- Monthly statistics are sent on the configured day (default: 1st of month)
- The adapter automatically saves current monthly data before resetting statistics
- Statistics use saved data from
statistics.lastMonth*states - Configuration: Ensure monthly statistics are sent after the last day of the month (e.g. 1st at 09:00)
Weekly Statistics
- Weekly statistics are sent on the configured weekday (default: Monday)
- The adapter automatically saves current weekly data before resetting statistics
- Statistics use saved data from
statistics.lastWeek*states - Configuration: Set weekday (0=Mon, 1=Tue, ..., 6=Sun)
Configuration Example (openweathermap)

Between 23:00 and 06:00 (configurable), the following notifications are suppressed:
- ❌ Battery FULL (100%)
- ❌ Intermediate Levels (20%, 40%, 60%, 80%)
The following notification is always sent:
- ✅ Battery EMPTY (0%) – if "Ignore night mode for 0% battery" is enabled
Quiet Mode (configurable)
Between 12:00 and 15:00 (configurable), all notifications are suppressed:
- ❌ Battery FULL (100%)
