1.1

The charger reports more than 1.0 kept. This release stores and shows all of it.

• Per-phase voltages and currents, neutral included
• WiFi signal history (RSSI and SNR, sampled every five minutes)
• The remaining lifetime counters: the raw alert counter, contactor cycles under load and charger uptime
• Grafana gains a charger-state timeline plus phase, session-energy and WiFi panels and six counter stats
• The built-in page gets matching phase and lifetime tiles
• Everything new is also exposed on /metrics

Existing databases are migrated in place on first start — just pull the new images.
