Emporia Electric Vehicle Charger

Setup / Can’t Connect

Do I need to open specific network ports for my Emporia device to access the internet?

The Emporia devices use the following ports to communicate with the Emporia Cloud: 80 (outbound), 443 (outbound), and 8883 (inbound/outbound).

Does Emporia offer any APIs?

Not at this time. Offering an API is a feature that is on our roadmap, but right now we don't have a specific release date. We are a small team with limited resources. We appreciate your feedback and hope you understand that we're working very hard to prioritize the many enhancements that have been requested.

How do I reconnect my EV Charger to WiFi? (New WiFi Router / New Internet Service Provider / Changed Wifi SSID or Password)

On your phone:

  • Ensure all app permissions are enabled for the Emporia Energy app.

In the Emporia app:

  • Make sure you're nearby the EV Charger.
  • Tap on the menu icon (three bars, upper left corner) and go to Manage Devices
  • Select your EV Charger from the list
  • Tap Reset WiFi
  • Go through the setup process and enter your WiFi credentials when prompted
The EV Charger won't connect to my network.
  • Ensure you have a strong WiFi signal nearby the EV Charger
  • Double check you're trying to connect to a 2.4GHz network and that your mobile device is also connected to the same WiFi network (won't work on 5.0GHz networks).
  • Check router settings:
  • Double check WiFi password - is case sensitive.
  • Security protocol set to WPA, WPA2, WEP.
  • WiFi/802.11 protocol set to B, G and/or N (not AX, AN).
  • Channel Assignment set to "Auto" or "Automatic".
  • No firewall settings preventing communications. Also possible that another device or program is scrubbing network traffic like Pi-Hole or a VPN.
  • If possible, try connecting the EV Charger to your mobile phones' WiFi hotspot to see if that can work. Can reset WiFi connection after the EV Charger has downloaded updated firmware (which can help connect to the local WiFi network).
  • If still having connection issues, contact Customer Support
Why won't the EV Charger start charging?
  • Ensure EV Charger is turned "on" in the app.
  • Ensure EV Charger is plugged into vehicle.
  • Double check there are no settings/configuration on the vehicle preventing charge. Things like vehicle locks, car scheduling and others can impact this behavior.
  • Reach out to Customer Support.

Installation

Can aluminum wiring be used for the hardwire power supply?

Aluminum wiring is not recommended in this situation. An electrician would be able to confirm and help if Aluminum wiring can work in your specific use case.

Can I use the EV Charger without a WiFi connection?

Yes, the EV Charger can be used offline, but its functionality will be limited. The EV Charger will need to be connected to the internet to change settings like charge rates and schedules - but once setup both of those settings should be stored on-device and used in offline situations.

I'm receiving a fault code/error in the app (or on the charger LED's) - what should I do?
If I don't connect the EV Charger to WiFi, what is the default charge rate?

If unable to connect the EV Charger to the internet, it'll be limited to the default/factory setting of a 40A charge rate.

What is the length of the provided NEMA cable?

Each EV Charger will come with a 22" NEMA cable to plug in.

What is the maximum charge rate if I hardwire the charger?

If hardwired, maximum amperage can be 48A without issue.

What is the maximum charge rate if I use a NEMA plug?

When using a NEMA plug to provide power to the EV Charger, the maximum amperage should be set no higher than 40A. This is important as any higher can cause damage to the EV Charger.

What size are the terminals inside of the charger to connect a hardline to?

The power supply terminals on the interior of the EV Charger are designed for #6 (gauge) wire.

What size is the conduit for a hardwire power supply?

Conduit spacing on the case for the EV Charger is designed for 1-1/4" conduit.

Will I need an electrician to install the EV Charger?

If you have an available 14-50 NEMA recepticle/outlet in your installation location, then you shouldn't need an electrician to install. If you are planning to hardwire the charger or need to install a NEMA recepticle at the installation location, then you will probably need an electrician to help (and is required in many cases).

Will the EV Charger work for my vehicle?

The EV Charger will work with the majority of electric vehicles on the market today. It has an SAE J1772 type of plug to connect to the vehicle which is fairly standard. Will also work with Tesla vehicles with a Tesla provided adapter for the J1772 specification.

If unsure, feel free to reach out to Customer Support for confirmation.

Emporia App

Can I control my charger behavior remotely?

Yes - as long as the EV Charger is connected to a local WiFi network, then its behavior can be managed from anywhere else in the world with access to the internet and through the Emporia Energy app.

Can I set a maximum charge rate for the EV Charger?

Yes. You can set a real-time charge rate in the app as well as a maximum charge rate in the app. That charge rate will be affected by the allowable power from the breakers as well as installation style (NEMA or hardwired).

Can I turn off my charger? (to prevent others from using it)

Yes, you can turn on/off the charger from the Emporia Energy application (mobile or web).

  • From the Home screen in the Emporia Energy app, select your EV Charger by tapping the battery/car icon to the left of the charger name.
  • Tap the circular button in the middle of the screen. That circuilar button will most likely have a lightning bolt icon in the center, but other icons may appear depending on the state of the charger.
How can I change the real-time charge rate?
  • From the Home screen in the Emporia Energy app, select your EV Charger by tapping the battery/car icon to the left of the charger name.
  • On the Control page, you can move the "Set Charge Rate" slider to the appropriate amperage and the charger should respond immediately.
How can I set the maximum charge rate setting?
  • From the Home screen in the Emporia Energy app, select your EV Charger by tapping the battery/car icon to the left of the charger name.
  • Select the Settings menu (gear icon) in the upper right corner of the Control page.
  • Select "EV Charger Info"
  • Select the appropriate maximum amperage via the "Dedicated Breaker / Max Charge" dropdown and tap "Save".
How can I setup a schedule for the EV Charger?
  • From the Home screen in the Emporia Energy app, select your EV Charger by tapping the battery/car icon to the left of the charger name.
  • Select the Settings menu (gear icon) in the upper right corner of the Control page.
  • Select Schedule
  • Can select between custom scheduling and Time of Use schedules (as provided by your utility).

Important: Make sure to pause the charger in the app so it is on "Standby" mode prior to the start of the schedule. If the vehicle is plugged in when the charger is in the "Ready" state, the charge will start immediately rather than waiting for the schedule to start. Also important if setting up a custom schedule that you create both a start charge scheduled time/event as well as an end charge scheduled time/event.

Will EV Charger schedules work if the device is offline/not connected to the internet?

Yes. The EV Charger will need an internet connection to setup (and edit/remove) schedules, but once added they'll be downloaded directly on the device firmware and should be followed even when offline.

Will the EV Charger track charge history by vehicle?

Not at the moment. The EV Charger will track charge sessions over time but won't be able to distinguish which vehicle was charged. This is functionality we would like to add in the future.

Hardware

Can I control my EV Charger via an API or local/on-device access?

Not at the moment, all EV Charger functionality is managed through the Emporia Energy app.

Can I monitor my Emporia Product with more than one mobile app?

Yes, simply install the Emporia Energy app on the other phone/mobile device and login with the same email address and password (account information) that you used to set up the Emporia device.

Is the EV Charger certified?

Yes, the EV Charger is UL Certified (file #E528156)

Why is my EV Charger only charging to "XX" amps when I have it set higher?

In most of these situations it'd be the vehicle restricting the charge rate rather than the EV Charger. You should double check the allowable charge rate (in amps or kW) for your vehicle through the owners manual. Can reach out to Customer Support if there is an issue/discrepancy.

Will the EV Charger work in countries outside the US? (240V electrical systems, single or three phase)

No. The EV Charger was only designed to work on split-phase 240V AC circuits.
