myenergi zappi charger — weak wi-fi in one room
Why does my myenergi zappi charger weak Wi-Fi in one room?
The short answer
App shows the charger offline even though it charges the car fine. On the WiFiXpert Compatibility Index the myenergi zappi charger scores 58/100, and its weakest check is "Works on 5 GHz" — which is exactly where this problem comes from. Not offered on the hub.

Free fixes, in order
- Move the hub closer to the garage wall — it needs to reach the charger, not just the router.
- Plug the hub into the router with a cable and use the app to check it appears.
- Restart the hub before re-pairing anything.
Before you spend anything
- A hub relocation or a longer cable first; extra myenergi kit only if the charger is genuinely out of reach.
