Zappi displays E019, charging disabled, often when linked with myenergi hub or other myenergi devices

Safety first: Communication faults do not usually affect electrical safety but may affect smart features.

• 1. Check hub status: Ensure the myenergi hub is powered, connected to the network, and showing normal status LEDs.
• 2. Verify pairing: In the Zappi menu, check that the hub and any linked devices (eddi, harvi, etc.) are correctly paired and visible.
• 3. Reduce interference: Move the hub closer to the Zappi or away from large metal objects and other RF sources (Wi‑Fi routers, microwaves).
• 4. Re-pair devices: Remove and re-add the Zappi in the hub/app, following myenergi’s pairing procedure.
• 5. Firmware update: Update firmware on both Zappi and hub to the latest versions.
• 6. If RF module is faulty: Persistent E019 with good signal and correct pairing may indicate a failed RF module on the Zappi PCB, requiring board replacement.
