# ============================================================
# ESPHome - Shelly 1PM Mini Gen4
# Gira System 55 aan-uit schakelaar
# ============================================================
#
# Schakelmodi:
#   - Detached:  Schakelaar stuurt events naar HA, relay wordt
#                door HA-automations aangestuurd.
#   - Toggle:    Elke schakelactie togglet de lamp.
#   - Volgen:    Schakelaarstand = lampstatus (aan/uit).
#
# Fallback:
#   Wanneer er GEEN verbinding is met Home Assistant (geen WiFi
#   of API), valt de schakelaar automatisch terug op Toggle-modus
#   zodat de lamp altijd lokaal bedienbaar blijft.
