Get to know your Ohme Home Pro
Now you have your Ohme Home Pro, we've created this page to help understand your EV charger so you can get the most out of it and deal with any potential hiccups along the way. Follow these steps to get used to the app features.
Getting to know what’s on the screen
+

With the Ohme Home Pro, you can start a charge and edit a current charge session as well as review various statuses from the unit’s screen. To get started, plug the cable into your vehicle and follow the instructions below depending on what you want to do:

Start a max charge session

Starting a max charging session will override any charge sessions currently active and charge a plugged-in vehicle until it is full.

To start a max charge from the Ohme Home Pro's screen, you will first need to make sure that your car is plugged in. The Ohme Home Pro’s screen will then display the phrase “smart charging” or 'car connected' if it detects that a vehicle is connected. Next, tap the blue button under 'max charge', after which the screen should turn red and your vehicle will begin charging.

If you need to stop a max charge session early, simply tap the blue button under 'stop charge'. The screen will then go back to blue and the percentage of charge added during the charge schedule will be displayed. If you would like the resume the max charge session, tap the blue button on the left under 'charge now'. From this screen, you can also set a target charge by tapping the middle blue button. To stop the max charge session completely, unplug your vehicle.

Edit a charge session

Tapping on 'edit charge' will allow you to make changes to the current charge schedule in place.

To edit the current charge session from the Ohme Home Pro’s screen you will first need to make sure that your car is plugged in; the Ohme Home Pro’s screen will display the phrase 'smart charging' or 'car connected' if it detects that a vehicle is plugged in. Next, tap “edit charge” and edit the target percentage using the left button and middle button to adjust the number on the screen. When you’re happy with your target percentage, tap 'next'. On this screen, you will be given the option to change the time that you want your charge session to stop using the left and middle buttons to add or subtract in 30 minutes increments. Tap 'done' when finished editing your target finish time.

Set up and edit a charge schedule
+

If you have a multi-rate energy tariff such as Octopus Go or EDF Goelectric, setting up a charge schedule is one of the easiest ways that you can save money on car charging costs.

You can also set multiple schedules up to suit different scenarios if you like, but for now, try setting up your first schedule:

  1. Open the Ohme app
  2. Tap the menu option in the top left corner of the screen (the icon looks like three small solid lines)
  3. Tap 'charge schedule'
  4. Tap the blue circle with a plus inside located on the bottom corner of the screen
  5. Name the schedule
  6. Select the days that you want your charge schedule to be active on using the icons. You can also select the 'weekdays' or 'weekends' icons if you prefer.
  7. Set a target range/battery percentage of 100 miles (or whatever you need each day) using the slider
  8. Set a finish time, for the time that you need your vehicle to be charged by each morning.
  9. Tap “Create” at the bottom to save your charge schedule.

Once done, your newly created charge schedule should appear in the charge schedule menu. Here you can edit a current charge schedule simply by tapping on it. You can also turn a schedule on and off using the toggle switch located on the right side of the schedule.

To add another charge schedule, simply repeat the process above.

Adding your energy tariff
+

The Ohme Home Pro can communicate with your energy provider and charge your vehicle according to your energy tariff’s off-peak rate (if you have a multi-rate tariff). Doing this also allows you to see how much each charge session costs as well as what type of energy has gone into your vehicle (i.e. renewable or non-renewable).

To add your energy provider and tariff you will need to:

  1. Open the Ohme App
  2. Tap the menu button
  3. Select the “tariff” option (If you have successfully paired the tariff to your app this will option will show “Tariff: Your Tariff”)
  4. Choose the supplier you are currently with.
  5. Enter your postcode.
  6. Some suppliers offer multiple tariffs and if yours is one of them then you’ll need to select the tariff you are currently with (If your tariff doesn’t appear on the list then please see the solution in the troubleshooting section).
  7. After confirmation, set the “never charge above rate” to the price you want your charger to be limited to if you want to do so.
Setting a price cap
+

If you have a multi-rate energy tariff and would like your Ohme Pro to only charge during your off-peak hours, regardless of your target range, then there’s an easy way to do this. Follow these steps:

  1. Tap the menu in the top left corner of the app
  2. Select the option “charge schedule”
  3. Tap the cog in the top right hand corner
  4. Tap the ‘limit charging over a certain cost’ toggle icon
  5. In the ‘cost’ box, enter the price rate that you would like your Ohme Home to stop charging at.
  6. Tap save changes.

Remember: if you select this option it will override your charging schedule and Ohme will stop charging once your electricity rate goes above this price. Therefore it may not meet your desired target range. Keep this in mind if you have a long journey planned as you may need to disable this setting. The Ohme app will alert you if it cannot reach the amount of miles you want.

Adding your vehicle to your Ohme Profile
+

In order to provide accurate data on your charging sessions, Ohme recommends that you add your vehicle make and model to your account. 

This is because Ohme can communicate with some vehicles using an API (Application Programming Interface), which is a system that allows the charger to access information such as the vehicle’s state of charge (SOC) and battery level. Sadly, only a handful of manufactures disclose their vehicle’s API information. These manufacturers are:

  • Renault
  • Tesla
  • Nissan
  • Jaguar
  • Hyundai
  • BMW
  • Kia

If you don’t have a vehicle from a manufacturer that discloses their vehicle’s API then fear not, you’ll still be able to access many of the features that the Ohme Home has to offer but they might require a few additional steps.

For example, say if you want to charge your vehicle to 80% of its battery after your commute to and from work. You’ll need to look at how much charge you have leftover after your commute and adjust your charge schedule so that it adds the percentage needed to reach the target.

Adding your vehicle from a manufacturer that shares their API information

  1. Tap the menu button in your Ohme App.
  2. Tap the “settings” option
  3. Tap “change car”
  4. Select your vehicle's manufacturer.
  5. If you have an online account with your vehicle’s manufacturer, tap account sign in, and enter your credentials. Skip to step 8
  6. If you don’t have an online account with your manufacturer, tap connect without an account.
  7. Select your vehicle’s model
  8. Tap 'done' on the confirmation screen.

Adding your vehicle from a manufacturer that doesn’t share their API information

  1. Tap the menu button in your Ohme App.
  2. Tap the “settings” option
  3. Tap “change car”
  4. Select the “other” option at the bottom right corner
  5. Select your vehicle’s manufacturer and tap either "account sign in" if you have an account with your vehicle's manufacturer or "connect without an account" if you don't
  6. Choose the model of your vehicle (Pay attention to the battery capacity and kW input. For example, if you have a 2011 24kWh Nissan leaf with a 3.3kW charger onboard select “Leaf 24kWh / 3.3kW 2011”)
  7. Tap 'done' on the confirmation screen.

Charger isn't working? Try these steps first!
Most EV chargers are very reliable and should charge your vehicle as intended. However, there are lots of variables when it comes to charging an electric car that can occasionally interrupt this. It's worth checking the below before moving on to the more advanced troubleshooting steps further down the page, as there could be a very simple solution to the problem.
Is there power to the unit?
+

The best way to tell if the Ohme Home Pro is receiving power is by checking if the screen on the front of the unit is on and displaying information. If the screen is black, then this could mean that there is no current reaching the unit. If you are finding that this happening to your Ohme Home, then we advise that you check that the circuit breaker to your unit isn't off or tripped.

If the circuit breaker is set to the on position but your charger still does not power on, please contact Ohme via:
Email: help@ohme-ev.com
Tel: +44 (0) 20 3375 1586

Can you charge your car at all?
+

If you have not paired your Ohme Home Pro with your Ohme app, the unit will act as a 'dumb charger' and should start charging your unit straight away.

If you have paired your Ohme app with your Ohme Home Pro, you should be able to go onto the main screen of your Ohme app to find out if your unit has recognised the vehicle you have plugged into it. The screen on the front of the unit should also display the phrase “smart charging” or “car connected” if it detects that a car is plugged-in. If both of the above are occurring when you plug in your vehicle, you should be able to tell the Ohme Home Pro to start charging or obey your charge schedules via the app or the unit’s screen.

If you can't do any of the above or your vehicle doesn't start charging after you have confirmed that you want to start a charge session then it means that there could be a fault with the unit and you will need to contact Ohme the support section of their website or by using the contact details in the drop-down above.

Have you tried resetting the unit?
+

Now we may be sounding like your local PC repair helpline when saying this but, have you tried turning it off and on again? Sometimes all the charger needs is a good old-fashioned reset (Also known as ‘power cycling’ in the EV world), below is how you do it.

  1. Locate the circuit breaker that your charger has been connected to, this can either be found within your main consumer unit or installed as a separate switch.
  2. Once you have found the switch, pull it down to the off position for 10 seconds. This will allow any residual charge to drain away and the charger to power down completely.
  3. After waiting 10 seconds, push the switch back up to the “on” position and wait for the charger to power back on.
  4. If a successful connection has been established, the Ohme screen should begin powering on.
Update the app
+

The Ohme app should be keeping itself up to date with the latest firmware automatically, but it’s always worth checking to see if the app is up to date via the app store on the iPhone or the Google Play on Android.

It goes without saying, if your problem is that your Ohme is not connecting to mobile data (You can check this by looking at the signal strength indicator located in the top right of the LED screen on the front of the unit) then that is a separate issue that needs fixing.

Ohme Home Pro Advanced Troubleshooting
My Ohme Home Pro acts as a “dumb charger” and charges my vehicle as soon as I plug it in rather than waiting for the set off-peak times or charge schedules.
+

First things first, make sure that you have added your energy tariff and set a charge schedule with a price cap. If you're unsure of how to do this then please see the advice above.

If you have done the above and the issue persists then the next thing you will want to check is your charger’s network connection. To do this, first tap the button labelled “info” on the main menu of your Ohme Home Pro’s screen and check for a signal strength indicator.

If you are not seeing a mobile signal strength indicator or the unit’s screen is displaying a network connection error even after resetting the charger then this could be the result of a faulty unit and you will need to contact Ohme regarding the issue.

The Ohme Home Pro and Ohme app won’t display my vehicle’s state of charge
+

When it comes to the Ohme Home Pro, some features on the app work better with some vehicles than others. This is because Ohme communicates with vehicles using an API (Application Programming Interface), which is a system that allows the charger to access information such as the vehicle’s state of charge (SOC) and battery level. Sadly, only a handful of manufactures disclose their vehicle’s API information. These manufacturers are:

  • Renault
  • Tesla
  • Nissan
  • Jaguar
  • Hyundai
  • BMW
  • Kia

If you have a vehicle manufactured by one of the brands above then you’re in luck! Once set up, you’ll be able to do things like set charge schedules that charge your EV to a specific percentage. You will also see your vehicle’s battery percentage on the Ohme Pro’s screen when it’s connected.

If your vehicle manufacturer doesn’t share their API then the battery percentage indicator on the screen of the Ohme Pro that appears when a vehicle is plugged in will always stay at 0%

My energy tariff isn’t listed in the tariff options
+

Ohme takes most energy providers into account when it comes to setting up the price cap on your charger, however, there is always a chance that your provider isn’t listed, especially if they are one of the less well-known providers. If you don’t see your tariff listed then you’ll need to enter your details manually. To do this:

  1. Select the tariff option in the menu bar.
  2. Scroll down to the bottom until you see the “Create new tariff” option
  3. Select either “Fixed price tariff” or “Variable price tariff” depending on your tariff type

Variable tariffs

  1. Enter the start and end of your off-peak hours (This timespan can be found on your electricity bill. If it isn’t, contact your provider).
  2. Enter the price per kilowatt (p/kWh) of your off-peak hours (Again this can be found on your electricity bill or by contacting your provider)
  3. Enter the price per kilowatt (p/kWh) you pay at all other times outside of your off-peak hours and press continue.
  4. Chose your time zone and select if your meter runs on daylight savings (If you are unsure if your meter does or not, please contact your provider). After this, tap continue
  5. Enter the name of your tariff (i.e. EDF GoElectric) and tap save.

Fixed Tariffs

  1. Enter the price per kilowatt-hour that your provider charges (this can be found either on your energy bill or by contacting your provider) and tap continue
  2. Enter the time zone you are in and select if your meter runs on daylight savings (If you are unsure if your meter does or not, please contact your provider). Once done, tap continue.
  3. Enter the name of your tariff (i.e. EDF GoElectric) and tap save.

After entering your variable or fixed tariff, you should get a confirmation screen appear telling you that your tariff has been set up successfully. After you’ve tapped “okay” on the confirmation screen, you’ll be greeted with the options to edit or change your tariff.

I’m getting error messages telling me that my car is charging lower than expected
+

There are a few reasons as to why this can happen:

Firstly, some cars can limit the level of charge they take in. If you have this feature enabled and the limit is set to lower than the level of charge your Ohme Home Pro is outputting then you will receive an error message on your Ohme app. To fix this, you’ll need to go into your vehicle’s charge settings (Each manufacturer does this differently so if in doubt, check your owners manual) and either turn the limit off or set it so that the charge limit matches the Ohme Home Pro’s charge output (7.4kW).

Another reason why this problem can occur is because you might have selected a vehicle model on the app that has a higher charging capacity than the vehicle you own. For example, if you have a 2014 Nissan Leaf with a 3.3kw charger onboard and you select the version of the Leaf with the optional 6.6kw charger onboard. With the charger thinking you have a higher charger capacity on your vehicle than your vehicle actually has, the Ohme Home Pro will base its charge schedule calculations on that higher charge output which triggers an error message when it can't reach that charge capacity.

To fix this, you’ll need to:

If the manufacturer shares their API information

  1. Tap the menu button in your Ohme App.
  2. Tap the “settings” option
  3. Tap “change car”
  4. Select your vehicle's manufacturer.
  5. If you have an online account with your vehicle’s manufacturer, tap account sign in, and enter your credentials. Skip to step 8
  6. If you don’t have an online account with your manufacturer, tap connect without account.
  7. Select your vehicle’s model
  8. Tap done on the confirmation screen.

If the manufacturer doesn’t share their API information

  1. Tap the menu button in your Ohme App.
  2. Tap the “settings” option
  3. Tap “change car”
  4. Select the “other” option at the bottom right corner
  5. Select your vehicle’s manufacturer and tap either "account sign in" if you have an account with your vehicle's manufacturer or "connect without account" if you don't
  6. Choose the model of your vehicle (Pay attention to the battery capacity and kW input. For example, if you have a 2011 24kWh Nissan leaf with a 3.3kW charger onboard select “Leaf 24kWh / 3.3kW 2011”)

Tap done on the confirmation screen.
