Navigate to the Home tab and scroll down to “Explore our Lab.” Tap the “Get Started” button on the section labelled “Intelligent Octopus Go.” If you don’t see this section but your smart meter is properly configured, it’s likely Octopus Energy is unable to connect to your meter at the moment. Wait awhile before trying again, and contact Octopus if the problem persists.

Tap “Add my car” and select your car model from the provided list. If you don’t see your car’s model, scroll down to the bottom of the page and tap “request an integration.”

Tap “Set up charger” and select your home charger from the list. If you don’t yet have a home charger, choose the “No charger” option. If you can’t find your specific charger model, you can also tap “request an integration” at the bottom of the page.

Tap “Start tariff switch.” Read the necessary terms and conditions, then agree to them by ticking the box at the bottom of the page. Tap “Start my switch.”

Octopus Energy will now connect to your car to verify that they can control it for scheduled charging sessions. Tap “Connect Device,” which will prompt you to connect to your Tesla. Tapping “Go to device login” will redirect you to the Tesla website.

Log in to your Tesla account. Tick the boxes for “Vehicle Information” and “Vehicle Charging Management,” then tap “Allow.” Note that you need to select both boxes, otherwise Octopus will not be able to charge your car.

A sign reading “Device connected” will confirm the connection is successful. From here, tap “Add virtual key.” You can skip this step if you have a Tesla Model X or Model S from earlier than 2021. In this case, simply tap “Virtual key added or not required.” Otherwise, clicking “Add virtual key” will take you to a Tesla screen.

Open your Tesla app and tap “Allow third parties to access your vehicles.” From there, navigate back to the previous Tesla screen and tap “Finish setup.” Go back to the Octopus app and tap “Virtual key added or not required.”

Tap “Test connection” and follow the app’s instructions to perform a test charge. If the test charge succeeds, the app should take you to a completion screen and display your car in the Devices tab.

Most simple problems with your charger can be resolved by simply resetting the unit. Follow these steps to reset the Tesla Wall Connector:

1. Find the circuit breaker your charger is connected to.

2. Turn the circuit breaker off and leave it alone for around 10 seconds. This gives you time for any residual current to drain out.

3. Turn the circuit breaker on.

4. Wait for your charger to turn back on. If you see a solid green light on the front of your unit, then the charger has been successfully reconnected.

When you plug the Tesla Wall Connector’s charging gun into your vehicle, you should see a green light streaming down the strip to signal that it has commenced charging. You may also see a solid blue light if your vehicle has a set charging schedule. If you see neither of these and your vehicle doesn’t seem to be charging, it’s likely your unit is faulty and you’ll need to get in touch with Tesla to resolve the issue.

The light strip on the front of your Tesla Wall Connector is there to signal that it’s receiving an electrical current. If it’s unlit, it generally means that no power is reaching your unit. If this is the case, check your circuit breaker in case it’s off or tripped.

The most common reason a charger might trip is because of the PEN fault detection identifying a voltage spike at the property. Elecology installs a PEN fault consumer unit for the Tesla Wall Connector that records the voltage at the time of tripping. The LCD screen will record the voltage and confirm if it is the cause.

In the UK, the declared voltage and tolerance for an electricity supply is 230 volts -6%, +10%. This gives an allowed voltage range of 216.2 volts to 253.0 volts. If the voltage is outside the allowed rating, then the Distribution Network Operator (DNO) needs to resolve the fault by reducing the voltage at your property. You’ll need to rectify this right away for the sake of other electrical devices in your house besides your charging point, as high voltage will degrade all electrical equipment. You can find your DNO here.

Here’s what to do in case this happens:

1. Take a picture of the LCD screen on your consumer unit and make a note of the time your charger trips.

2. Voltage can fluctuate daily. If it happens again, reach out to your DNO and report the issue.

3. The DNO will install a monitoring device that records the voltage over a set period of time. From there, the possibilities are as follows:

   1. If the voltage is peaking, then it’s the DNO’s responsibility to resolve it.

   2. If the results show normal readings, please reach out to Elecology so we can request additional data from Tesla.

   3. If the voltage is within the tolerance level, then we can arrange a site visit to help you figure out the problem.

The charger itself doesn’t lock the cable in place. Your electric vehicle controls the charging port lock. To untether the cable, do the following: 

• Make sure the vehicle has ended the charging session before trying to disconnect the cable.

• Refer to your vehicle’s user manual for instructions on how to end the charging session. Typically, there’s a button to unlock the charging port, which may be located in the centre console, near the driver’s door, or on the key fob.

This may be because your vehicle is set to charge at a later scheduled time. It can also be because the vehicle is already fully charged. It’s also possible that there’s an error with the vehicle, so check for any warning messages. If the vehicle is not charging due to improper connection, try unplugging and reconnecting the charging cable. You can also clean and inspect the charging plug to ensure that this issue is not caused by debris or damage to the plug. 

Three blinking red lights indicate that your unit may be malfunctioning due to high temperatures. This is a rare problem in the UK, but you may encounter it on certain hot days during the summer. Simply leave the charger alone for a few minutes to let it cool down.

Incorrect installation may also cause your charger to display high-temperature warnings. Check for faulty installations by feeling the charger’s faceplate and the charging gun’s handle. If it feels excessively warm, please stop using your charger for the time being and contact Tesla.

If you see four blinking red lights on your charger, it’s having trouble connecting to your Wi-Fi network. Check your Wi-Fi router to make sure that it’s functioning properly and connected to the internet.

Recent password changes will require you to update your charger with your new connection details. Please see the above section on connecting to the Wi-Fi network for how to do this if you don’t remember.

In the event that your router is fully functional but your charger still can’t connect to it, the signal strength around your charger might be the problem. Elecology will always ask you to check your signal strength at the charger location before we go ahead with your installation, but it also helps to recheck it periodically afterwards, especially if you start experiencing connectivity problems you didn’t have before. If you’ve moved your router recently, that might be interfering with your charger’s ability to connect.

To check your signal strength, bring any Wi-Fi-enabled mobile device near your charger and count the number of bars on the signal strength indicator. If you’re on a smartphone, you’ll find this indicator on the top right corner of the screen.

As mentioned above, a solid red light may indicate an internal fault. Try resetting your circuit breaker, and if you continue to experience this problem, contact Tesla.

If you have an issue not listed above or none of the above advice has worked for you, get in touch with Tesla for direct support. You can do this by calling them at 0800 756 9960 or logging into your Tesla account and accessing their customer service page.
