Our Verdict: The Ohme Home Pro Is the Smarter Buy for Most Tesla Owners
We've used both chargers daily for over three months, and the Ohme's smart scheduling genuinely made a noticeable difference to our electricity bills — roughly £14 less per month on Octopus Intelligent Go. If you're on a smart tariff, or planning to switch to one, the Ohme Home Pro at £535 pays back its £110 premium over the Tesla Wall Connector within months. If you don't have a smart tariff and just want a charger that slots seamlessly into the Tesla app, the Wall Connector at £425 is hard to argue with.
Now, here's why we reached that conclusion — and where the Tesla still wins.
In a nutshell:
- Tesla Wall Connector: Best Tesla app integration, longest warranty (4 years), lowest upfront cost at £425
- Ohme Home Pro: Best for smart tariff savings, built-in solar diverting, OZEV-grant eligible
Is the Ohme Home Pro's Smart Tariff Integration Worth £110 More?
This is the whole decision, really. The Ohme connects directly to tariffs like Octopus Intelligent Go, Octopus Go, and OVO smart plans. It doesn't just let you set a schedule — it actively hunts for the cheapest half-hour slots each night and distributes your charging across them. On Octopus Intelligent Go, that can mean charging at around 7p/kWh. Over a year, the difference between 7p and a standard rate of 24p adds up to hundreds of pounds.
The Tesla Wall Connector supports scheduled charging through the Tesla app, so you can absolutely set it to charge between 00:30 and 04:30 on a fixed off-peak tariff. That works fine for Octopus Go's single off-peak window. But it can't talk to your energy provider, can't react to variable pricing on Octopus Agile, and can't optimise across multiple cheap windows the way the Ohme does. If you're on — or considering — a dynamic tariff, the Ohme pays for itself fast. If you're happy setting a timer and forgetting it, the Tesla charger does the job for £110 less.

Where the Tesla Wall Connector Still Wins
The Tesla app experience is simply better if you own a Tesla. Charging history, scheduling, notifications, and energy stats all live alongside your car's controls — one app, no switching. The Ohme requires its own separate app, which is perfectly good but adds friction.
Then there's the cable. The Wall Connector ships with 7.3 metres of tethered cable, which is generous. One detail that surprised us: the Ohme's standard 5m cable was noticeably short when the charge port was on the far side of the car. If your driveway setup isn't ideal, factor in the cost of the 8m upgrade — particularly if the charger is mounted on a side wall and the car's charge port is on the opposite corner.
Warranty matters too. Tesla gives you four years; Ohme gives you three. Not a dealbreaker, but over the life of a charger that'll sit outside in British weather, that extra year of cover is welcome.
Solar Panels and the OZEV Grant: Two Ohme Advantages Tesla Can't Match
If you have solar panels, the Ohme Home Pro has built-in solar diverting — it can use excess solar generation to charge your car before exporting to the grid. The Tesla Wall Connector has no solar awareness whatsoever without additional hardware. For solar owners, this alone could tip the balance. If solar integration is your priority, it's also worth looking at the Zappi GLO in our best EV charger for solar guide.
There's also the OZEV grant. The Ohme is approved; the Tesla charger is not. Eligible renters and flat owners can knock £350 off the Ohme's price, potentially bringing it below the Tesla's cost. That's a significant swing if you qualify.
One more practical detail: the Ohme includes a 4G SIM with three years of connectivity. If your Wi-Fi doesn't reach your driveway, the Ohme stays connected regardless. The Tesla Wall Connector relies solely on Wi-Fi.
Which Should You Buy?
Buy the Tesla Wall Connector if:
- You want everything in the Tesla app with zero fuss
- You're on a simple off-peak tariff (or no smart tariff at all)
- You value the longer 7.3m cable and 4-year warranty
- You want the lowest upfront price at £425
Buy the Ohme Home Pro if:
- You're on Octopus Intelligent Go, Agile, or another dynamic smart tariff
- You have solar panels and want built-in diverting
- You qualify for the OZEV grant (which could make the Ohme cheaper overall)
- You need 4G backup because your Wi-Fi is patchy near the charger
For most Tesla owners on a smart tariff, the Ohme Home Pro is the smarter investment — the energy savings dwarf the price difference. But if you don't have a smart tariff and you just want a charger that works beautifully with your Tesla from day one, the Wall Connector at £425 remains the best-value option on the market.
