To remotely manage Chargifi SmartSpots, troubleshoot, monitor, and obtain insights into wireless charging sessions, you need to connect the SmartSpots to the following WiFi bands depending on the version of SmartSpots you have purchased:
- V2: 2.4 GHz
- V3: 2.4 GHz or 5 GHz
SmartSpots can connect to the following WiFi networks:
Our SmartSpots do not support enterprise WiFi authentication such as WPA-802.1x mode. WPA-Enterprise mode is not suitable for headless IoT devices such as Chargif Neutrons and Cloud Gateways. The EAP types that are used for authentication and the range of different RADIUS servers on the market vary widely.
Captive Portal and HTTP Authorization
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).
For Chargif Cloud v2, each SmartSpot 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 that matches the number of SmartSpots you are planning to install and accommodate.
For Chargifi Cloud v3, each Cloud gateway requires its own IP address.
Access Point Capacity
Each SmartSpot maintains its own connection with the wireless network.
Ensure your network has enough capacity for the number of SmartSpots you are planning to install.
WiFi Frequency Bands
V2 SmartSpots support only 2.4GHz with 20MHz channels.
V3 SmartSpots support either 2.4GHz or 5GHz.
There are three regional models: US, EU, and Asia.
Please contact your local Chargifi partner for further details.
The SmartSpots will need to connect through certain TCP ports. This is for device-server communication, firmware upgrades, and fallback ports for communication.
Ensure your firewall allows outbound traffic on TCP ports 443, 80.
The Chargifi Cloud infrastructure does not have a restricted IP range that can be used in firewall rules. Upon network activation, SmartSpots will build a TLS tunnel to the Chargifi Cloud, then keep a two-way communication channel open. There is no need for the network administrator to open any inbound firewall ports.
WiFi Credential Updates
When your WiFi network credentials (SSID and/or password) are updated the SmartSpots will lose connection to the Chargifi Cloud, and a manual update will need to be performed on each SmartSpot.It is not possible to remotely update network credentials.
Every SmartSpot maintains a continuous two-way connection to the Chargifi Cloud. The following guidelines can be used when estimating the bandwidth required per SmartSpot per day.
If we assume the SmartSpot 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
SmartSpots send telemetry data to the Chargifi Cloud in order to remotely manage and troubleshoot SmartSpots, and give insights into Chargifi sessions.
We do not collect any personal data from users who are wirelessly charging devices.
