Proxy Tasmota energy JSON into Homepage's customapi widget, which can
render JSON but cannot do arithmetic. Applies the tariff, sums across
plugs, and records the per-day history the plugs do not keep.
Plugs are fetched in parallel; sequential polling would stack five
timeouts into a 25s hang. An offline plug is reported rather than
counted as zero, so a dead sensor cannot read as "consumed nothing".
Tasmota exposes only Today/Yesterday/Total, so each poll writes
yesterday's finished kWh into SQLite keyed (day, plug), making repeat
polls and restarts idempotent.
Display strings are preformatted server-side: Homepage's locale
formatting renders 1593 W as an ambiguous "1,593", and its widget has
no columns, so pairing kWh with its cost in one value is what keeps
the cards compact.
