Zen Link update

Never unplug it while the light is steady blue: it is installing, which takes up to about 45 seconds.

Automatic (V2 and upgraded V1)

1. Plug in the Zen Link.
2. Let it join your Wi-Fi. About 30 seconds later the update starts by itself.
3. If it drops into Bluetooth setup instead, the saved Wi-Fi details are wrong: fix them in the Zenlink app and let it reconnect.

• Fast blue blink: downloading.
• Steady blue: installing.
• Steady green, then a restart: done.
• Three orange flashes: failed. It keeps the old version and retries later; check your internet if it keeps happening.

V1 one-time upgrade

1. Hold the blue Config button on the Zen Link V1.
2. Keep holding it while you plug the Zen Link in.
3. Open the ZenLinkConfigurator.
4. Enter your Wi-Fi name and password.
5. Select Native Mode.
6. Wait: the update begins shortly after it joins Wi-Fi.
