nilsandClaude Opus 5.5 582c084b35 Live dashboard: show what the car sends, compute pack energy 
The car publishes no battery, cabin or outside temperature and no pack
energy (checked against the fields that reached InfluxDB). Instead of
panels that stay empty:

- Battery temperature tile -> Climate setpoint.
- Outside temperature tile -> Last update ("2 minutes ago").
- Energy in pack = SOC x usable capacity, from the hidden dashboard
  constant usableKwh = 50.8 (51 kWh battery).
- Temperatures chart -> Battery voltage and current.

Checked with a simulated drive carrying exactly the car's fields: all
11 panels return data, energy matches 61 % x 50.8 kWh. SPECS.md lists
the missing signals and why.
