Who are Myenergi?
Myenergi are a manufacturer of home energy management devices. Its award winning EV charger, zappi 2.1, and the new zappi GLO seamlessly connect together into an ecosystem for customers. And it’s now compatible with Charge Anytime.
zappi 2.1 and GLO are now compatible with Charge Anytime
Charge Anytime, our home EV charging add-on, is now compatible with myenergi zappi 2.1 and zappi GLO chargers. It's free to add on to your account and lets you smart charge your EV at home for a lower charging rate of 7p per kWh1, day or night, saving you up to £542 a year 2.
If you have a zappi 2.1 or zappi GLO charger and are already using Charge Anytime through a vehicle connection, you may find it useful to switch and connect with your charger. This would mean you remove your vehicle connection to Charge Anytime and then reconnect directly with your newly compatible zappi charger. The charger connection could be a better choice if you have multiple EVs that aren’t all compatible.
The zappi 2.1 and zappi GLO charger models are solar compatible, so you can make full use of your home charger set up when adding Charge Anytime. OVO can install a zappi charger at your home - you can find out more here.
Onboarding with your zappi
So you can onboard to Charge Anytime successfully you’ll need to make sure that your zappi charger is on the correct firmware and the CT clamp on your charger is installed with the correct orientation:
Firmware: zappi devices must be on the latest version of firmware to be able to onboard to Charge Anytime. Please update your firmware by following the instructions before onboarding to Charge Anytime.
CT clamp orientation: You will also need to ensure that when your zappi device is installed the CT clamp orientation is the correct way round. The arrow needs to point in the direction of the import (e.g. towards the consumer unit if on the live cable). You can find more information about the role of the CT in the myenergi ecosystem and rules for CT clamp installation. The below image in the MyEnergi app shows the correct flow if your CT clamp is installed correctly. The arrows must be flowing from the grid (red icon) towards the centre leaf and on towards the house (pink icon). If you need support with this please contact the myenergi support centre who can help get you set up.
Once successfully connected, your zappi will switch to Managed Mode. This means:
- Charging schedules and boost controls are managed entirely via the Charge app (download from the App Store or Google Play).
- Local changes such as scheduling or mode switching will be disabled
- Manual boost remains available on the device if the internet connection is lost
- Charge Anytime will create a schedule based on grid demand and your charge preferences.. If you have a Solar CT clamp, solar generation will also be factored into scheduling decisions

¹ When you add Charge Anytime to your plan, your home energy rate will stay the same, but the energy used to charge your EV will be charged at an effective rate of 7p per kWh when smart charging (this is applied as a monthly charging credit). Individual costs will vary based on your vehicle efficiency, driving style and weather conditions. Subject to eligibility and acceptance of our terms and conditions.
If you need your car in a hurry, you can override your smart charging schedule with the Charge Now function. You'll be charged at your standard home electricity rate when you're not smart charging.
² Actual sum is £542.81. The £542.81 saving is based on an average Charge Anytime customer using 3100kWh a year to charge their EV using the Charge Anytime add on. The Charge Anytime rate on 01/07/2025 is 7p per kWh for Charge Anytime charging compared to the OVO’s UK average SVT rate of 24.51p per kWh. Actual savings will vary depending on vehicle efficiency, driving style, EV charging usage and the cost per kWh of your standard home energy tariff.
