v1.20.0 — Wh support, yearly costs, WP benchmark fix
What's New
Wh Unit Support
All energy sensors now automatically detect and convert Wh → kWh. No more manual helper entities needed for systems that report in Wh.
Yearly Costs in Amortization
New "Yearly Cost" field under Prices & Amortization. Enter insurance, maintenance costs etc. (€/year) — they are proportionally deducted from total savings.
Heat Pump Benchmark Fix
New "Heat Pump Commissioning Date" in Benchmark settings. When set, the yearly WP consumption is calculated from the total sensor value ÷ actual operating days — instead of extrapolating from short delta-tracking periods.
