What it does not do

Wi-Fi

• 2.4 GHz only. The setup page says I need 2.4GHz. I can't see 5GHz-only networks.
• WEP, WPA and WPA2 networks, not WPA3. The setup page’s own words: I can join WEP, WPA and WPA2 Wi-Fi, but not WPA3.
• No networks with a sign-in page: hotels, cafés, most guest networks, and corporate networks that want a username. See Hotel, cafe and public Wi-Fi, Office and corporate Wi-Fi.

Data

• US dollars only; no other currency.
• Cryptocurrencies only; no stocks, metals or currencies. See Does it show stocks or gold?.
• No price alerts or notifications; it displays, it does not warn. See Can it alert me when a price moves?.
• No wallet or exchange connection. See Can it connect to my wallet or exchange?.

This model

• No touch screen and no screen rotation; the shipped firmware for this model leaves both out.
• No clock card; the ticker has no clock of its own and shows no time.
• No manual update button and no way to switch updates off: they arrive by themselves.

Software

• No app and no account: a browser on your Wi-Fi is the whole interface. See Is there an app?.
• No cloud control: the settings page is reachable only on your own network.
