MyEnergi Zappi Troubleshooting

We strongly recommend you leave your Zappi powered on all the time, to ensure a stable and consistent connection with Amber. 

I can't connect my Zappi to Amber

We have a step by step guide for connecting your Zappi to Amber, which you can read here 
 

Troubleshooting steps when you can't see that your Zappi is connected to Amber

1. You’re with Amber at this address.
   Open the Amber app → Settings → Ensure the property shows Active (not Pending). If it’s Pending, that means we're waiting for Amber to become your retailer, which we need to do before we connect to your Zappi.

2. Your Zappi is associated with a myenergi account
   You must have a Myenergi account to complete the connection between Amber and your Zappi. 
   Sign in to myaccount.myenergi.com → Myenergi Products → your Zappi should appear here.
   If it doesn’t, add it with the Serial + Registration code (ask your installer if needed).
   If it’s registered to someone else, like the installer, they must release it before you can add it (ask your installer if needed).

3. OCPP is enabled and pointed at Amber
   In Myenergi Products → OCPP settings → toggle OCPP On, choose Amber in the dropdown (this auto-fills the Backend URI), and enter the Chargebox ID shown in the Amber app when you linked the charger. Allow up to ~2 minutes for the connection to be confirmed.

4. Reboot the Zappi and wait ~2 minutes. 
   Perform a reset in your Myenergi app. 
   Switch the power off and on or perform a reset in your Myenergi app.

5. Check your Wi-Fi.
   The Zappi must be online for Amber automation to work.

6. Model requirements
   Amber only supports Zappi model v2 and later. If you have a model v1 Zappi (serial number starts with a 1) you will not be able to use the Amber automation. 

7. Firmware requirements
   In order for Amber to integrate with your Zappi, you will need firmware v5.114 or later (released July 2023). We'd recommend the firmware be kept up to date on the most recent version for best performance. To update your firmware:
   For V2 Zappi, follow these instructions

   For V2.1 Zappi follow these instructions

Zappi charges the EV when I plug it in

You may notice that sometimes your Zappi will charge your EV when you plug in. 

There are 2 known causes.

1. After a reset of the zappi, or after a power outage.
   If you want to stop this occurring, you can choose to change the 'default mode' in your Zappi settings. See the below video on how to do this. 
    

2. Zappi starts charges a little but after plugging in. Sometimes after plugging in the EV, the Zappi might charge for a short time and then stop. This is caused by delays in Amber's system detecting that charging has started automatically. Charging should usually stop within 1 to 2 minutes. 

Can I do solar charging with my Zappi and A4EVs

Yes, with the right hardware setup.

Zappi’s native Solar modes (ECO/ECO+) work with A4EV via OCPP when CT clamps are installed and configured to measure grid, generation, and (for AC systems) battery. A4EV can then switch the Zappi’s Mode (Eco/Eco+) at the right times (when solar is available to charge your EV with).

Without CT clamps installed, you will have a poor experience. The ECO+ mode won’t behave as expected and may sit in a “Waiting for surplus” status. We recommend not enabling Solar mode in A4EV until CTs are present. 
 

Solar charging is causing some unwanted exports / spill to the grid

It is strongly recommended that if you have a Zappi, Solar, and a Battery, that you get CT clamps installed.

Likely causes & fixes

For DC coupled batteries, your export margin may be too low. Increase Zappi’s Export Margin a little bit more (e.g., ~100 W) so the EV waits for a small, steady surplus. This reduces seesawing with the home battery and grid spill, at the cost of slightly slower solar capture.

For AC coupled batteries with CT clamps. Make sure to set Avoid Drain/Avoid Both so the battery isn’t back-filled by the EV while exporting.

CT configuration: Confirm CT clamps are present, clipped in the correct direction, and mapped to the right circuits (grid/gen/battery). Without correct CTs installation, ECO+ decisions are blind and grid spillage can be common. Talk to your installer if you need help changing your CT clamp configuration.
