Walli charger causes lights in the house to flicker or dim when charging starts.

Safety first: Significant flicker can indicate dangerous wiring conditions.

Steps:

• Check circuit design: Confirm that the Walli charger is on a dedicated circuit with appropriate cable size and breaker rating.
• Reduce current: In the Walli app or installer settings, lower the maximum charging current and observe if flicker is reduced.
• Inspect connections: Have an electrician check all terminations in the main panel and at the Walli for tightness and signs of overheating.
• Consider load management: If the supply is limited, enable Walli dynamic load balancing (if available) or schedule charging during low‑load periods.
