TamaFi V2 is a pocket virtual pet that treats nearby Wi-Fi and Bluetooth activity as its environment. When it goes hunting, the radio activity it finds changes hunger and mood, while it can also choose behaviors such as discovering open networks or taking a rest.

Nearby radio activity is classified as calm, busy, open, noisy, or hostile. Detecting deauthentication or disassociation activity can lower comfort and happiness and trigger a glitch-like facial reaction. The current firmware is read-only and does not store SSIDs or MAC addresses. It was created by CiferTech.
