Ohme Home Pro vs myenergi Zappi

Price

myenergi sells the zappi only as a unit, at £779 untethered for the 7kW model (a little more tethered), and routes buyers to installers for a quote. OVO lists it from £949 fitted. Ohme sells the Home Pro from £999 including installation, and through Octopus Energy it costs £1,199. The charger alone is about £532 at wholesalers.

OVO’s price is the exception. Across five installer price lists in our data that quote both chargers, the zappi cost the same as the Ohme at one (Renew-Able Solutions, £1,099) and £100 to £241 more at the other four. Charge EV North West, for example, quotes the Ohme from £965 and the zappi from £1,095, and Mint Energy £949 against £1,190.

Smart features and tariffs

Octopus lists both as generally available for Intelligent Octopus Go. Ohme’s integration is the longer-standing and is controlled in the Ohme app. The zappi also works with OVO Charge Anytime on the 2.1 and GLO models, provided it has the latest firmware and the CT clamp is fitted the right way round. Ohme dropped out of OVO’s scheme on 15 July 2025.

Connectivity is the practical difference. The Ohme uses a built-in 4G SIM. The zappi has Wi-Fi and Ethernet but no 4G, and myenergi says it needs a 24-hour internet connection to work under the Smart Charge Points Regulations. Check your signal at the wall before buying either. Ohme adds a colour screen, a price cap and multi-car profiles. myenergi adds an ecosystem of the eddi hot-water diverter, the libbi home battery and the harvi wireless clamp. Neither advertises OCPP.

Solar

This is the zappi’s strongest point. It has three modes: Eco blends solar with grid power, Fast ignores solar, and Eco+ uses surplus only and pauses rather than import from the grid. A grid CT clamp with a 5m cable is in the box, and the three-phase model comes with three clamps.

Ohme does solar well enough for most homes. Solar Only starts at 1.44kW of surplus and Solar Boost from 0.72kW plus grid power. It needs a working CT clamp, which is in the box, and a charger installed from January 2023. If solar is the main reason you are buying, the zappi’s Eco+ mode is the cleaner fit. If you want solar and cheap-rate charging from one low-cost unit, the Ohme is enough. Our solar EV charging guide explains the options.

Installation and safety

The zappi is large, about 439 x 282 x 122mm according to a retailer listing, against 170 x 200 x 100mm and 4kg for the Ohme. Trade listings give the zappi IP65 and IK10, against IP55 and IK08 for the Ohme. The zappi comes tethered with a 6.5m cable or untethered, in black or white, and in 7kW or 22kW versions. The Ohme Home Pro is tethered only, with a 5m or 8m cable, and single-phase only; the untethered alternative is the ePod.

Both have built-in PEN fault protection and 6mA DC detection, so neither normally needs an earth rod. The Ohme also has a Type A 30mA RCD built in. myenergi’s UK guidance still requires a separate upstream 30mA Type A RCD, and it says wiring regulations require your installer to fit a separate surge protection device. Our PEN fault and earthing guide explains the protection.

Reliability and owners

The What Car? 2025 owner survey is brand-level and sits on a page marked as sponsored by Pod. It ranked Ohme fourth of 11 with 5, 5, 3 and 4 stars for installation, reliability, fault repairs and overall. Its fault rate was 13%, with 27% of faults unresolved. myenergi came joint fifth with 4, 3, 3 and 3 stars, a 20% fault rate and 27% unresolved, and about half of its problems ended in a replacement unit. The sample is brand-wide, so it says little about a specific zappi.

Specific zappi complaints are few in our data, beyond the OVO onboarding requirements. Ohme’s are about connectivity: dropping offline and defaulting to a peak-rate Max charge, and a platform outage from 16 to 19 August 2024.

Warranty

Both give three years as standard. Ohme’s covers parts and labour including on-site help, and covers the 4G data for the same period. What Car? says myenergi’s can be extended to five years, but we could not verify the terms or the price.

Verdict

We score the Ohme Home Pro 7.4 and the zappi 7.0 out of 10. The Ohme wins on value, size, 4G and survey record. The zappi wins on solar and on range of options: three-phase, untethered, OVO support.

Choose the Ohme if Intelligent Octopus Go matters most, you want a compact unit, or Wi-Fi is weak at the wall. Choose the zappi if solar generation or a three-phase supply drives the decision, or you are with OVO. Read the Ohme Home Pro review and myenergi zappi review, or see our best home EV chargers.
