Booster Lights

Booster lights and what they mean
Light What it means
Amber = Charging

If the Booster is plugged in to USB power, the amber light indicates the onboard battery is charging and/or the thermometer is charging. (With older firmware, the light may blink amber. If it does, please update your firmware.)

In portable charger mode, press the button (light). An amber light response indicates the thermometer is still charging.

The indicator will turn off after 5 seconds.

Green = Charged!

When plugged in, that means the Booster is charged and the Predictive Thermometer (if it's in there) is also fully charged.

In portable charger mode, press the button (light). A green light response indicates the thermometer is fully charged.

The indicator will turn off after 5 seconds.

Blinking White x3 = Searching

A repeated pattern of 3 white blinks indicates that the Booster is searching for linked tools within range.

It will only connect to Combustion tools that have been linked already.

Follow the linking steps above.

Single White Blink = Connected/Repeating

When the Booster is connected to a Predictive Thermometer (either directly or via another Booster/Display), it will repeat and rebroadcast the signal.

A single white blink indicates this connection is live! The blink will repeat every 5 seconds.

Quick Red Blink = Low Battery When the onboard battery is low, the Booster will repeat a very quick red blink. Time to recharge it!
Overlapping Patterns?

It's possible that more than one light pattern will be triggered at a time.

For instance, a Booster which is recharging itself (blinking amber) may also be repeating (single white blink).

If you see a confusing light pattern, it's most likely two simple patterns that are overlapping.
