To remotely manage Chargifi Spots, troubleshoot, monitor, and obtain insights into wireless charging sessions, you need to connect the Spots to the following Wi-Fi bands depending on which version of Spots you purchase:
V2: 2.4 GHz with 20 MHz channels
V3: 2.4 GHz or 5 GHz
Spots can connect to the following Wi-Fi networks:
- Our Spots do not support enterprise Wi-Fi authentication such as WPA-802.1x mode. WPA-Enterprise mode is not suitable for headless IoT devices such as Chargifi Neutrons and Cloud Gateways. The Extensible Authentication Protocol (EAP) types and the range of different RADIUS servers on the market vary widely.
- Captive portals were designed for humans, not IoT devices, so we are unable to connect to networks with sign-in pages such as captive portals (ICMP or DNS) or HTTP authorization (e.g. terms of service pages).
Internet Protocol (IP) Addresses
If you're deploying V2 Spots, each Spot requires its own IP address. Individual IP addresses can be assigned dynamically using a DHCP network management protocol. Chargifi Cloud cannot set the IP address statically.
Ensure your network has a minimum number of available IP addresses in its subnet to match the number of Spots you are planning to install.
If you're deploying V3 Spots, each Cloud Gateway requires its own IP address.
Each Spot maintains its own connection with the wireless network.
Ensure your network has enough capacity for the number of Spots you are planning to install.
There are three regional models: US, EU, and Asia.

Transmission Control Protocol (TCP) Ports
The Spots connect through certain TCP ports for bidirectional device-server communication, firmware upgrades, and fallback ports for communication.
Ensure your firewall allows outbound traffic on TCP ports 443 and 80.
The Chargifi Cloud infrastructure does not have a restricted IP range that can be used in firewall rules.
Transport Layer Security (TLS) Tunnels
Once activated, Spots build a TLS tunnel to Chargifi Cloud, then keep a two-way communication channel open.
There is no need for the network administrator to open any inbound firewall ports.
If your Wi-Fi network credentials (SSID and/or password) change, Spots that have already been installed and activated will lose their connection to Chargifi Cloud. To reconnect, configure each Spot again with the updated network details.
Network credentials can only be updated using the Installer app, not remotely in Chargifi Cloud.
For more information, see Configuring Spots.
The following guidelines can be used when estimating the bandwidth required per Spot per day.
If we assume the Spot is online 24 hours a day and has 20 charging sessions per day, then the following estimates apply:
Upload: 218 kilobytes per day
Download: 10 kilobytes per day
Spots send telemetry data to the Chargifi Cloud so that you can manage and troubleshoot Spots remotely, and obtain insights into Chargifi sessions.
We do not collect any personal data from users who are wirelessly charging devices.
