Ohme Home Pro vs Easee One

The £50 that decides how hard your charger works

The Ohme Home Pro costs £539. The Easee One costs £489. Both deliver 7.4 kW on single-phase, both carry a three-year warranty, and both have built-in cellular connectivity so neither depends on your Wi-Fi reaching the drive. The £50 between them buys one specific thing: the Ohme talks to your energy supplier; the Easee does not.

• Ohme Home Pro — £539, tethered, direct API integration with Octopus and British Gas. It chases cheap half-hours on your behalf.
• Easee One — £489, untethered, built-in RCD and open-PEN detection. It saves on install, not on electricity.

What the Ohme's £50 buys on a smart tariff

The Ohme Home Pro has direct API links to Octopus and British Gas. On Octopus Intelligent Go — 8p/kWh across a six-hour off-peak window, with the supplier able to slot extra cheap sessions into the small hours — the Ohme is the officially recommended charger. It does not merely schedule; it receives instructions from the grid operator and responds in real time. The Easee One cannot do this. Its app offers manual scheduling — set a start time, set a stop time — and nothing more.

On Octopus Agile, where rates shift every thirty minutes and can drop to 5p/kWh or below overnight, the difference is starker. The Ohme watches the price curve and charges during the cheapest slots automatically. The Easee, locked to a fixed window, will charge through a 20p half-hour because it has no way of knowing better. Over a year of typical mileage, that gap comfortably exceeds £50. Often double it.

On Octopus Go — a flat 8.5p/kWh between 00:30 and 05:30 — the Ohme's intelligence matters less. A manual timer set to 00:30 does the same job. The Easee handles that fine.

Where the Easee claws back the difference — and then some

The Easee One's argument is not about electricity. It is about the bill from the electrician. A built-in Type B RCD and open-PEN detection mean the installer does not need to add either at the consumer unit. That typically saves £100–£200, depending on the board. Against the Ohme's install estimate of £400–£500, the Easee can land noticeably cheaper all-in, even before you account for the £50 lower unit price.

At 1.5 kg, the Easee is also the lightest charger on the market by a wide margin — the Ohme weighs roughly 3.5 kg — which makes mounting on plasterboard or awkward walls less of a headache. If your installer has quoted a surcharge for a difficult fixing, the Easee removes it.

The trade-off: the Easee is untethered. You carry your own Type 2 cable, plug it in each time, and coil it back up afterwards. For some drivers this is a feature — a clean wall when the car is away, and the option to use the same cable at public destinations. For others it is a nightly annoyance. That is a personal call, but it is worth being honest with yourself about it before you buy.

The IP rating and the connectivity question

The Ohme carries an IP65 rating — fully sealed against dust and water jets. The Easee is IP54, the lowest in this price bracket. Both will survive British rain, but if your charger sits on an exposed wall with no overhang, the Ohme's rating offers more margin.

Both chargers have built-in cellular backup. The Ohme includes a 4G SIM for three years; the Easee's eSIM is lifetime, with no ongoing fee. On connectivity alone, the Easee edges it — no renewal to remember, no lapse after year three. Whether that matters depends on whether your Wi-Fi reaches the charger anyway.

Which to buy

Buy the Ohme Home Pro if:

• You are on, or plan to switch to, Intelligent Go, Agile, or British Gas EV Power — the tariff integration pays for itself quickly
• You want a tethered cable ready to plug in without rummaging in the boot
• You have solar panels — the Ohme's built-in solar diverting needs no extra hardware

Buy the Easee One if:

• Your consumer unit is old, full, or awkward — the built-in RCD saves real money on install
• You charge on a flat rate or a simple off-peak tariff like Octopus Go, where a manual timer does the job
• You prefer an untethered socket and a clean wall between sessions

For most Tesla owners choosing a smart tariff — and you should be choosing a smart tariff — the Ohme Home Pro is the stronger buy. The £50 premium is modest; the electricity savings are not. The Easee makes sense when the install is the expensive part, and the tariff is the simple part. If your electrician quotes £700 for consumer-unit work and the Easee brings that down to £500, the maths flips. Otherwise, spend the £50 and let the charger earn it back.
