Ohme: The Smart Tariff Charger
Ohme is an Irish-founded company (established in Dublin, now headquartered in London) that has built its reputation on one core idea: the home EV charger should automatically work out the cheapest time to charge and do it without any input from the user.
Where other chargers require you to set a schedule manually (start at 23:00, stop at 07:00), the Ohme app connects to live electricity price data and configures charging automatically to the cheapest periods. This is a meaningful differentiator for Irish EV owners who want completely hands-off optimisation.
Ohme offers two main home products: the Ohme Home Pro (7.4 kW, tethered) and the Ohme ePod (7.4 kW, tethered, simpler model). This review covers both.
Specifications: Ohme Home Pro
7.4 kW (32A, single-phase)
Tethered Type 2 cable (5m or 7.5m)
Wi-Fi, Bluetooth, OCPP 1.6J
Yes — auto-scheduled, tariff integration
Type B DC fault detection built-in
Specifications: Ohme ePod
The ePod is the simpler, more affordable Ohme product:
- 7.4 kW, tethered 5m cable
- IP55 rating (better than the Home Pro)
- Wi-Fi and Bluetooth, OCPP
- Smart scheduling and tariff integration (same app, same features)
- Smaller, more compact form factor than Home Pro
- SEAI approved, eligible for €600 grant
Both Home Pro and ePod deliver the same charging power and smart functionality. The Home Pro has a larger screen for on-device status display; the ePod relies entirely on the app.
The Defining Feature: Automatic Tariff Integration
What genuinely differentiates Ohme from the Easee One and Wallbox Pulsar Plus is automatic electricity tariff integration. Here is how it works:
- You connect your electricity account to the Ohme app (currently works directly with several UK suppliers; in Ireland, manual tariff input is used)
- You set your departure time — when you need the car to be charged by (e.g., 08:00)
- You set your desired charge level (e.g., 80%)
- The Ohme app automatically calculates the cheapest possible charging window within your departure constraint and schedules accordingly
In practice for Irish users in 2026, full automatic tariff integration with Irish suppliers is partially implemented. Irish users typically input their tariff’s night window manually (e.g., “night rate window 23:00–08:00 at 13 c/kWh”). The Ohme app then schedules charging automatically to this window, stopping the session once the target charge level is reached.
The Irish roadmap for Ohme includes direct integration with the main Irish electricity suppliers — Electric Ireland, Energia, Bord Gáis, and SSE Airtricity. Users with Octopus Energy (which has expanded into Ireland) already benefit from full automatic integration through the Ohme/Octopus partnership.
App Experience
The Ohme app (iOS and Android) is clean, intuitive, and more consumer-friendly than some competitor apps. Key features:
- Set and forget: Enter departure time, target charge, and desired battery percentage. Ohme handles the rest.
- Smart charge tracking: See exactly how many kWh were charged in each session and estimated cost
- Pre-conditioning: The app can notify the car to pre-heat/cool the cabin before departure (where the vehicle supports this)
- Charging history: Detailed session logs with cost and kWh data
- Notifications: Push notifications on session start, completion, and any interruptions
The app has received consistently positive reviews on the App Store and Google Play from Irish users, with particular praise for its simplicity.
Build Quality and Installation
The Ohme Home Pro is a tethered charger — a significant practical advantage for single-EV households who want the convenience of a permanently attached cable. The 5m tethered cable is good quality and connects to the wallbox housing via a strain-relief fitting that withstands repeated coiling.
The Home Pro is slightly larger than the Easee One or Wallbox Pulsar Plus, but its tethered cable is a meaningful convenience trade-off for most Irish homeowners.
Installation is standard — a Safe Electric registered electrician mounts the unit, runs the dedicated 32A circuit from the consumer unit, and commissions via the Ohme app. The Ohme Home Pro has built-in DC fault detection (no separate Type B RCD required on the incoming circuit).
Pricing and SEAI Grant
Ohme Home Pro supply cost in Ireland 2026: €450–€580
Ohme ePod supply cost in Ireland 2026: €350–€450
Typical installed cost (Home Pro): €1,000–€1,350
After SEAI Home Charger Grant (€600): €400–€750
The ePod offers a lower entry price with identical smart charging functionality — a good choice for price-conscious buyers who do not need the Home Pro’s on-device screen.
How Ohme Compares
The Ohme Home Pro is the best choice for Irish EV owners who:
- Want a tethered charger for maximum convenience
- Are on Octopus Energy (fully automated tariff integration)
- Value the simplest possible user experience (set departure time, forget)
- Do not have solar PV
Verdict
The Ohme Home Pro is a well-designed, SEAI-approved, tethered EV charger that excels at tariff-optimised smart charging. Its automatic scheduling approach is the most user-friendly of any charger on the Irish market — ideal for EV owners who do not want to think about charging configuration. The app is excellent, build quality is solid, and the tethered cable is a practical convenience for most Irish driveways.
Its absence of solar diversion capability means it is not the right choice for solar homeowners — the Zappi fills that niche. For everyone else, the Ohme Home Pro (or the more affordable ePod) is a compelling top-three option in the Irish home charger market.
Rating: 4.5/5
