TTLock G2 BLE Hub: The Entry-Level WiFi Gateway
If you have a TTLock Bluetooth smart lock and want remote access, the cheapest and simplest upgrade is a WiFi gateway. The SK-G2 TTLock G2 gateway is the entry-level choice — small, Type-C powered, and easy to set up.
What Does a G2 Gateway Do
The G2 connects to your 2.4G WiFi router, and talks to your TTLock smart lock over Bluetooth (BLE) within 10–15 meters. When you tap “unlock” in the TTLock App from anywhere, the command goes over the internet to the G2, which relays it to your lock. That turns a local Bluetooth lock into a remotely controllable one.
LED Status Lights: What They Mean
The G2 has a single LED that tells you what is happening:
- Red and blue flashing alternately – standby mode, ready for pairing.
- Blue light on – working mode, connected to WiFi and locks.
- Red light on – network failure, check your WiFi.
