Blink Sync Module lights: what each LED pattern means

The Sync Module is online and connected to your network. One exception from Blink’s troubleshooting article: an offline Sync Module XR with a MicroSD card can also show this.

Applies to: Sync Module Core, XR, 2 and 1st Gen.

What to do

Blink Support gives no step for this light on the page cited; the meaning above is all it says.

The Sync Module is starting up.

Applies to: Sync Module Core, XR, 2 and 1st Gen.

The Sync Module is in pairing mode and ready to be set up.

Applies to: Sync Module Core, XR, 2 and 1st Gen.

What Blink says to do

1. In the Blink app, tap + at the top right of the Home screen, then Sync Module. Scan the QR code on the back of the device or tap Enter Serial Manually, and pick or create a system.
2. With this light showing, tap Discover Device. Blink says to check its LED article if a different pattern shows.
3. Join the temporary Wi-Fi network BLINK-xxxx (xxxx is the last four digits of the serial number), then choose your own Wi-Fi network and enter its password. Blink says the Sync Module may then update its firmware, which can take a few moments.

The Sync Module has gone offline and is trying to reconnect to the network it was set up on. Blink names power cuts, a changed Wi-Fi password, and interference from pods or extenders as causes.

Applies to: Sync Module Core, XR, 2 and 1st Gen.

What Blink says to do

1. Check that your Wi-Fi password has not changed since setup. If it has, Blink says to update the Sync Module with the new password.
2. Power-cycle your router: unplug it, wait 30 seconds, plug it back in.
3. Power-cycle the Sync Module: unplug it for 10 seconds, then plug it back in. Solid blue and solid green afterwards means it has reconnected.
4. Disconnect any pods or extenders so only your main router is on. Blink says you can reconnect them once the Sync Module is online.
5. If it is still offline, Blink says to delete the Sync Module and add it again.

The maker puts this light down to Wi-Fi or the network. If the problem is the router itself, its own lights are explained on the router and broadband hub lights page.

The Sync Module cannot connect to your network, or the Wi-Fi password entered may be wrong. Blink’s troubleshooting article places this during setup.

Applies to: Sync Module Core, XR, 2 and 1st Gen.

What Blink says to do

1. Check the Wi-Fi password. If the Blink app says “Incorrect Password for Your Wi-Fi”, re-enter it carefully and try again.
2. Put the Sync Module in the same room as your router, but not too close, and away from physical obstructions.
3. Turn off any VPN, firewall or anti-virus app on your phone, and any app Blink lists as conflicting with the Blink app.
4. Power-cycle the Sync Module for 10 seconds; blinking blue and solid green afterwards means it is ready for setup again. Power-cycle the router for 30 seconds.
5. Disconnect pods or extenders. If it still fails, Blink says to factory reset the Sync Module.

The maker puts this light down to Wi-Fi or the network. If the problem is the router itself, its own lights are explained on the router and broadband hub lights page.

The Sync Module is not plugged into an outlet, or there is a power issue.

Applies to: Sync Module Core, XR, 2 and 1st Gen.

What Blink says to do

Power. Blink links this light to the Sync Module’s power. The steps here are only Blink’s own, as its pages state them; semiatic gives no electrical instructions of its own.

1. Blink says to make sure the power adapter is firmly connected to both the Sync Module and the outlet (from its Sync Module XR steps).
2. Blink says to confirm the outlet works by testing it with another device, or to try another outlet.

Blink lists this among the signs of an offline Sync Module XR with a MicroSD card: a power problem, or a faulty or damaged card.

Applies to: Sync Module XR with a MicroSD card inserted.

What Blink says to do

Power. Blink links this light to the Sync Module’s power. The steps here are only Blink’s own, as its pages state them; semiatic gives no electrical instructions of its own.

1. Blink says to check the power adapter is firmly connected and the outlet works first.
2. Blink says to unplug the Sync Module, take out the MicroSD card and look for damage, replacing it if damaged.
3. Blink says to plug the Sync Module back in and reinsert the card only once it shows solid blue and green; if it goes offline again, the card may be faulty.
4. If it stays offline with a new card, Blink says to contact its Technical Support.
