LOW is the cheaper night rate, HIGH the day rate. Hours are local clock hours; the night window wraps past midnight. The season follows the clock change automatically — summer hours apply while daylight-saving time is in effect, winter hours otherwise.
Rain + open attic window: warn when rain is likely within the lookahead window and the attic window reads open.
Which Emporia channel is which. They are integrated into kWh and combined with the heat pump's heat counters to give today / last 24 h energy and COP (shown under Derived on the dashboard). "Heat pump system" = compressor + control + pumps. Leave a field empty to disable that channel.
A draw is detected when the DHW tank temperature drops by more than the threshold over the lookback period while the charging pump is off. A longer lookback catches slower draws but may detect natural cooldown.
Detection only applies to new readings by itself. To re-judge everything already stored (e.g. after changing the numbers above), save and recompute the history. Draws less than 15 minutes apart count as one.
