Zappi v2.1 vs Ohme ePod: Two Very Different Takes on Smart EV Charging
The Zappi and Ohme ePod are the two most frequently recommended smart chargers in the UK market, and they are aimed at genuinely different use cases. Buying the wrong one for your situation costs money — here is how to tell which fits.
The core difference
Zappi: Designed for solar households. Its primary intelligence is routing surplus solar generation into your car rather than exporting it at low Smart Export Guarantee rates. Without solar panels, most of its differentiating features are irrelevant.
Ohme ePod: Designed for tariff-smart grid charging. It integrates with time-of-use tariffs — particularly Octopus Agile and Go — to automatically charge your car when grid electricity is cheapest. Without a dynamic tariff, most of its differentiating features are irrelevant.
Zappi in detail
Three eco modes: Eco (supplements with grid to maintain minimum charge rate), Eco+ (only charges from solar surplus, no grid top-up), Fast (full 7.4kW regardless of solar). The CT clamp installation is mandatory — without it, the Zappi cannot see your solar generation.
Price: £779 installed. IP65. 3-year warranty. 6.5m tethered cable.
Works without solar as a standard scheduled charger, but you are paying a premium for functionality you are not using.
Ohme ePod in detail
Connects to Octopus Energy (and several other suppliers) via API. When you have an Agile tariff, it receives half-hourly pricing and automatically schedules charging for the cheapest periods — sometimes below 10p/kWh, occasionally negative prices. You set a departure time and target state of charge; the ePod figures out when to charge.
Price: £499 installed. IP55. 3-year warranty. 7.5m tethered cable. No solar divert.
Which one?
You have solar panels: Zappi — full stop. The solar divert payback easily justifies the £280 premium over the ePod within two or three years for anyone who drives regularly.
You are on Octopus Agile or a similar dynamic tariff, no solar: Ohme ePod. The tariff integration is seamless and the lower price is a genuine advantage.
You have solar AND a dynamic tariff: Zappi, and set it to Eco mode for daytime solar divert and scheduled charging for overnight off-peak top-ups. The Zappi handles both; the ePod only handles one.
You have neither solar nor a dynamic tariff: both chargers are premium products for use cases you do not have. Consider the Wallbox Pulsar Plus at a similar price point with simpler smart scheduling.
