Hello,
is it possible to connect the SCK 2.3 to eduroam?
I clicked on it, but since then it’s stuck on blue blinking and since then I cannot connect anymore with the wifi to the SCK.
Is there a way to connect the SCK to a WiFi hotspot of a phone?
Cheers,
Alessandro
The Smart Citizen Kit cannot currently connect directly to eduroam because eduroam uses WPA/WPA2-Enterprise (802.1X) authentication, while the SCK supports standard WPA/WPA2-Personal (PSK) networks.
The main difference is authentication. WPA/WPA2-Personal uses a shared Wi-Fi password, while WPA/WPA2-Enterprise authenticates each user or device individually through an 802.1X/RADIUS infrastructure, often using usernames, certificates or specific EAP methods.
The SCK Wi-Fi interface is based on the ESP8266 and operates on 2.4 GHz Wi-Fi. The current SCK firmware and configuration flow support standard WPA/WPA2-PSK networks, but do not implement the Enterprise/802.1X authentication required by eduroam.
This limitation is quite common in IoT devices, including commercial products from large vendors. For example, Google documents that Chromecast does not support WPA2-Enterprise/802.1X. The issue is therefore not specific to Smart Citizen, but reflects a broader mismatch between enterprise networks designed around authenticated users and IoT devices designed around persistent machine connectivity.
In universities and research institutions there is often a separate Wi-Fi network for sensors, displays, printers and other IoT equipment. It may not be publicly advertised. We recommend asking your IT department whether they provide:
This has also come up previously in the Smart Citizen community, where contacting the institution’s IT team to register the device on an appropriate network was the recommended solution.

And yes, you can also connect the SCK to a Wi-Fi hotspot from a phone . This is often the easiest workaround for testing, workshops or field deployments.
Just make sure the hotspot is available on 2.4 GHz and uses a normal WPA/WPA2-Personal password. The phone will also need mobile data if the SCK should publish measurements to the Smart Citizen platform.
A phone hotspot works well as a temporary solution. For a permanent installation, a dedicated institutional IoT network is usually preferable.
