WiFiXpert Compatibility Score — myenergi zappi charger
Uses a small hub indoors to reach the charger, so problems are usually between hub and charger, not hub and router.
Fussy — expect some setup pain
Eight checks, same for every device. The eight numbers below add up to 58.
The eight checks
| What we check | Rating | Points |
|---|---|---|
Works on 2.4 GHz The hub uses the long-range band. | Excellent | 14/14 |
Works on 5 GHz Not offered on the hub. | Not supported | 4/14 |
Modern Wi-Fi security Works with current router security. | Good | 9/12 |
Happy on mesh Wi-Fi The hub stays put; the link out to the charger is its own radio. | Fair | 10/16 |
Works on a guest network Setup needs your phone on the same network as the hub. | Poor | 3/8 |
Survives a plug-in extender Extenders don't help the hub-to-charger link at all. | Issues possible | 4/8 |
Doesn't depend on chatty discovery The hub reports to myenergi's servers. | Low dependency | 9/16 |
Easy to fix when it goes wrong The hub's screen codes need the manual to decode. | Medium | 5/12 |
| WiFiXpert Compatibility Score | 58/100 | |
What usually goes wrong
App shows the charger offline even though it charges the car fine.
Free things to try, in this order
- 1
Move the hub closer to the garage wall — it needs to reach the charger, not just the router.
- 2
Plug the hub into the router with a cable and use the app to check it appears.
- 3
Restart the hub before re-pairing anything.
Before you buy anything
A hub relocation or a longer cable first; extra myenergi kit only if the charger is genuinely out of reach.
Answers about this gadget
What it needs from your network
2.4 GHz client mounted outside, through at least one external wall.
- Bands it uses
- 2.4 GHz only on most models. It will not see a Wi-Fi name that is 5 GHz only, and setup fails silently if your phone is on the 5 GHz half of a split network.
- How it's found
- Cloud-based; scheduling and cheap-rate charging depend on it staying online.
- Background discovery traffic
- Low.
- On a guest network
- Setup fails.
- On a separate gadget network
- Fine on an IoT network.
Getting it set up
- • Get the installer to check signal at the charger position before drilling.
- • Many chargers also take a mobile SIM — worth it if the wall is thick.
- • Stand next to your router while you set it up, then move the gadget to where it lives.
- • Put your phone on the 2.4 GHz network name for the setup, or use one name for both bands so the phone can follow.
- • If your router splits bands into two names, turn the 5 GHz one off for five minutes rather than fighting it.
- • Turn mobile data off on your phone during setup — some apps quietly use it and never find the gadget.
With mesh Wi-Fi
- • A mesh box in the room nearest the charger, or an outdoor unit in the garage, is the usual fix.
If it simply won't play nicely
- A charger with a mobile SIM — Removes the house Wi-Fi from the equation for a garage or driveway unit.
