The Emporia EV Charger uses Bluetooth during initial setup and Wi-Fi for ongoing connectivity. This article covers both — what to do if the charger doesn't appear during setup, and how to resolve connection issues after it has been installed.
Charger Not Appearing During Setup (Bluetooth)
During the add device process, the Emporia app uses Bluetooth to detect your charger and send it your Wi-Fi credentials. If the charger doesn't appear in the app during setup, try the following:
Confirm Bluetooth is enabled on your phone
Make sure you are within close range of the charger — ideally within 10 feet
Verify the charger is powered on and the green power LED is illuminated
Force-close and reopen the Emporia app, then try again
If your phone is connected to a 5GHz Wi-Fi network, temporarily switching to a 2.4GHz network before setup can improve detection reliability
Restart your phone and try the setup process again
Basic Troubleshooting (Wi-Fi Connection Issues)
If your charger was previously connected but is now showing as offline or unable to reconnect, start here:
Power cycle the charger and router:
Turn off the charger at the breaker, wait 30 seconds, then turn it back on
Unplug your router, wait 30 seconds, then plug it back in
Force-close and reopen the Emporia app
Check signal strength: If the charger is far from your router, a weak signal may cause intermittent disconnections. Consider moving the router closer or adding a Wi-Fi extender. You can also connect the charger using your phone's mobile hotspot to confirm the charger itself is functioning correctly — if it connects via hotspot, the issue is your router or signal.
Wi-Fi Requirements
The Emporia EV Charger requires a specific type of Wi-Fi connection. Confirm your network meets all of the following:
2.4GHz network only — the charger cannot connect to 5GHz networks
Security protocol: WPA, WPA2, or WEP
Wi-Fi mode: B, G, or N (automatic channel selection)
No dual-layer security — networks that require a secondary login beyond the Wi-Fi password (such as hotel or guest networks) are not supported
Advanced Troubleshooting
If basic troubleshooting hasn't resolved the issue, try the following router and network adjustments:
Avoid special characters in your Wi-Fi network name (SSID) and password
Keep your SSID under 32 characters and password under 63 characters
Use a less crowded Wi-Fi channel — channels 1, 6, or 11 are recommended for 2.4GHz
Enable legacy mode (B/G/N mixed mode) in your router settings
Disable AP/Client Isolation if enabled on your router
Consider assigning a static IP to the charger via your router's DHCP reservation settings
Required network ports and domains (for IT-managed or business networks):
Port 80 (outbound), Port 443 (outbound), Port 8883 (MQTT inbound/outbound), Port 50001 (UDP inbound/outbound)
Domains: mqtts://prod-mqtt.emporiaenergy.com and udp://prod-udp-logs.emporiaenergy.com
