The best way to figure out what's going on with your Pulse is by pressing the reset / setup button, and reading the series of flashes from the device's indicator light. On our original square model, the reset button is located next to the power plug and you need a paperclip or pen to poke it, and the light is on the front. Our updated Pulse One has both the button and light under the battery cover. On the Pulse Pro, the button and light are on the side of the device.

After pressing the button, the light on the your Pulse will blink for about one minute (don't worry, this light turns off, and only turns back on if the Pulse loses power, and in no other circumstance).

For troubleshooting, only the sequence that happens soon after releasing the reset button matters. If it starts blinking red, but then goes to green/yellow after 30 seconds - it is the red sequence that is important for troubleshooting.

1. One long red, two short red:

This sequence means that the Pulse is looking for the wifi network, and cannot find it. Typically that is because the network name that the Pulse is looking for is incorrect, or is a 5GHz network. If you have trouble, contact support - support@pulsegrow.com or 1‑888‑53‑PULSE (888-537-8573)

Clear the configuration, correct the network name, and do blinkup again.

Alternatively, you can try renaming your wifi network to something simple, and then trying to connect again.

2. One long red, three short red

This sequence means that the Pulse has the wrong password saved to it - try confirming the password and trying again. If you continue getting the error, it could be an issue with your router. Try restarting your internet router (unplugging, waiting for 30 seconds, and plugging it back in) and then trying again.

Clear the configuration, correct the password, and do blinkup again. If you have trouble, contact support - support@pulsegrow.com or 1‑888‑53‑PULSE (888-537-8573)

3. Random red sequence when on battery power

This may mean that the batteries are too low. Switch to AC power, or replace the batteries.

1. Blinking yellow

This sequence means that the Pulse does not have any wifi information on it yet. Try doing blinkup again, make sure to read the tips in the "Before you begin" section here. If you have trouble, contact support - support@pulsegrow.com or 1‑888‑53‑PULSE (888-537-8573)

1. Solid green

This sequence means that the Pulse just performed a successful blinkup, and the wifi information on the device has been updated.

2. Faint, intermittent green blinking

This indicates some sort of power issues.

3. Blinking green

This sequence means that the Pulse is connected and working fine.

1. Alternating blinking green and yellow

This sequence means that the Pulse is intentionally disconnected. Restart the Pulse and check the light code it settles into. If it goes through a few sequences but reaches this light sequence in 5-10 seconds, everything is likely working fine.

All of these sequences should be short lived, and mean that the Pulse is going through the connection process. If they last for a while, you're likely having connection issues. Try resetting your router, waiting a minute, and then pressing the reset button on the Pulse. If you have trouble, contact support - support@pulsegrow.com or 1‑888‑53‑PULSE (888-537-8573)
