Highlights

Rain accumulation is now cleanly separated into two independent tracks. The web API provides rain-check corrected daily totals in rain_today / rain_yesterday. The device provides raw local totals in rain_today_local / rain_yesterday_local. Neither track can corrupt the other.

Changes

Separate Local and Web Rain Accumulation

Background: Two independent paths were writing to the same rain_today state:

• UDP path — reads the hub's own daily rain counter (hub index 18, resets at local midnight). Falls back to accumulating per-minute rain values when the hub sends shorter packets in power-save / low-battery mode (e.g. when Precipitation Failed appears in sensor_status).
• Web API path — reads precip_accum_local_day from WeatherFlow, which is always rain-check corrected and typically the more accurate total.

With both paths writing rain_today, the state alternated every ~60 seconds between the raw local value and the web value. In power-save mode this was especially visible: local showed "accumulated" while web showed a slightly different corrected total.

Additionally, the fallback accumulation used rain_today_raw_mm as its running baseline — the same state the web API wrote to. Each web poll would shift the baseline, causing the next per-minute delta to be added on top of a different starting point.

Fix — fully separated write ownership:

State	Written by	Contains
rain_today	Web API only	Rain-check corrected daily total
rain_today_raw_mm	Web API only	Same, in raw mm
rain_yesterday	Web API only	Rain-check corrected yesterday total
rain_today_local	UDP only	Device daily total (not rain-check corrected)
rain_today_local_raw_mm	UDP only	Same, in raw mm — accumulation baseline
rain_yesterday_local	UDP only	Device yesterday total (captured at midnight)
rain_today_source	UDP only	"hub" or "accumulated"

rain_today_source values:

Value	Meaning
hub	Hub index 18 present — device's own authoritative daily counter
accumulated	Hub index 18 absent (power-save / sensor fault) — plugin accumulating per-minute values as fallback

Web API is the primary source for most users. rain_today shows the rain-check corrected total and is the recommended state for automations. rain_today_local is available when you want the raw device value or need a value independent of web availability.

Midnight rollover: at midnight the plugin captures rain_today_local_raw_mm into rain_yesterday_local. The web API writes rain_yesterday from precip_accum_local_yesterday. Both yesterday states update independently.

Upgrade Notes

• No configuration changes required.
• The four new states are added automatically on the first observation after the plugin is reloaded.
• rain_today and rain_yesterday now update only when the web API polls (~60 s). They no longer update every UDP observation. Existing automations using these states are unaffected — values are the same, just sourced exclusively from web.
• If you were using rain_today as a real-time per-minute counter, switch to rain_today_local for that use case.
