Ohme Home Pro 7.4kW Smart EV Charger
Ohme Home Pro 7.4kW: deepest direct-API tariff integration with Octopus, sub-£1,000 fitted, 3-yr warranty. No solar; OVO support pulled Aug 2025.
4.2 / 5
☆☆☆☆☆
★★★★★
Pros
- Deepest direct-API tariff integration with Octopus (Intelligent Octopus Go, Go, Agile, Cosy)
- Built-in 3-inch colour LCD for on-charger control without opening the app
- 5m cable as standard, 8m option for awkward driveway runs
- IP55 rated for outdoor mounting; built-in O-PEN fault device removes the need for an external earth rod at most installs
- CT clamp included for dynamic load balancing against the household main fuse
- Three-year warranty as standard; sub-£1,000 entry price including installation
Cons
- No native solar diversion — Zappi v2 or Hypervolt with myenergi integration is a better choice for households with PV
- Lost OVO Charge Anytime app integration in August 2025; OVO customers must use the OVO app via vehicle telemetry instead
- Plain industrial design compared with rivals like the Hypervolt Home 3 Pro
- Vehicle-API integration for live state-of-charge depends on car make/model and is intermittent on some VW MEB models (ID.7 reports recur)
- In-session cost figure on the Ohme app does not match billed cost on Intelligent Octopus Go until Octopus reconciles slot data after unplug
