Ohme Home Pro vs myenergi Zappi GLO

The £60 between your tariff and your roof

These two chargers occupy the same price tier — £539 for the Ohme Home Pro, £599 for the myenergi Zappi GLO — and both carry a 3-year warranty and IP65 weatherproofing. On paper, near-identical. In practice, they point in opposite directions.

• Ohme Home Pro — talks directly to your energy supplier and chases cheap electricity half-hour by half-hour. The tariff charger.
• myenergi Zappi GLO — diverts surplus solar generation into your car, and slots into myenergi's wider home-energy ecosystem. The solar charger.

The question is not which is better-made. It is which resource you have more of: a smart tariff or a south-facing roof.

Why the Ohme wins on tariff savings

The Ohme's defining feature is its direct API integration with Octopus and British Gas. On Octopus Intelligent Go, the charger is officially recommended — it negotiates extra off-peak windows at 8p/kWh beyond the standard 23:30–05:30 block, shifting charge sessions into slots the Zappi GLO simply cannot see. On Octopus Agile, where rates change every thirty minutes, the Ohme tracks them automatically; the Zappi supports smart tariffs but lacks the same depth of supplier handshake.

There is also the 4G SIM, included for three years. If your charger sits at the far end of a driveway where Wi-Fi thins to nothing, the Ohme stays connected. The Zappi GLO is Wi-Fi and Bluetooth only — a limitation that matters more than it sounds when your router is two walls and a garage away.

For a Tesla owner on a flat-rate tariff with no solar panels, neither charger's premium feature earns its keep. In that scenario, the Tesla Wall Connector at £475 does the job for less. But the moment you move to a time-of-use tariff — Octopus Go at 8.5p/kWh off-peak, EDF GoElectric at 6.99p/kWh — the Ohme starts paying back its £539 in small, automatic increments.

When the Zappi GLO earns its £60 premium

Solar panels change the arithmetic entirely. The Zappi GLO's Eco+ mode charges your car exclusively from surplus generation — energy that would otherwise be exported at around 4–5p/kWh. Diverting a typical 3–4 kWh midday surplus into the battery instead means free miles, and over a year those free miles add up faster than any tariff discount.

The Zappi also fits into myenergi's wider ecosystem. If you already run an eddi for hot-water diversion or a libbi home battery, the Zappi GLO talks to both through the myenergi hub, letting the system prioritise where surplus goes. No other charger at this price integrates as tightly with a home energy stack. For solar homes considering battery storage too, the GivEnergy EV Charger at £444 is worth a look — but it plugs into GivEnergy's own ecosystem, not myenergi's. Our solar charger guide covers the full field.

The Zappi GLO also offers a 22kW three-phase option for the rare UK home wired for it, and a 6.5-metre tethered cable as standard — 1.5 metres longer than the Ohme's base cable. Marginal advantages, but real ones if your parking spot is further from the wall.

What both share — and where both fall short

Both carry 3-year warranties. That is fine, but not generous. The Tesla Wall Connector manages four years; the Wallbox Pulsar Max offers five. Both are OZEV-approved, so eligible renters and flat owners can claim the £500 grant — which, at these prices, covers the bulk of the hardware cost and chips into the install.

Neither charger is the cheapest smart option on the market. The VCHRGD Seven Pro at £430 and the Sync Energy Wall Charger 2 at £400 both undercut the Ohme by over £100. But neither matches its tariff integration or the Zappi's solar diversion — the premium here buys a specific capability, not just a brand name.

The verdict

Buy the Ohme Home Pro if:

• You are on, or planning to switch to, a smart tariff — especially Intelligent Go or Agile
• Your charger location is beyond reliable Wi-Fi range
• You do not have solar panels and want the lowest running cost per kWh

Buy the myenergi Zappi GLO if:

• You have solar panels and want to charge from surplus generation
• You already own myenergi hardware — eddi, libbi, or the hub
• You need the longer 6.5-metre cable or a three-phase connection

For most Tesla owners without solar, the Ohme Home Pro at £539 is the charger to fit. Its tariff integration does quiet, measurable work every night, and the built-in 4G means it stays online where cheaper units drop out. The Zappi GLO is the better product for the right house — but that house has panels on the roof. If yours does not, the £60 buys you a solar computer with nothing to compute.
