Voice Control Devices

Google Assistant

FireBoard works with the Google Assistant available on iPhone, Google Home, and most Android phones. All you have to say is “Okay Google, talk to FireBoard.”

If this is your first time, you’ll need to link your FireBoard account through the Google Assistant App.

Once you’re talking to FireBoard, you can say any of the following:


The FireBoard works with all Amazon Alexa enabled devices. Find and enable the FireBoard Alexa Skill in the Alexa Skill Store. Sign in with your FireBoard account through the Alexa App. Once linked, you’re ready to command Alexa. Say “Alexa, ask FireBoard what is the current temperature.”

Alexa can do much more than just check the temperature, try some of the phrases mentioned above for more functionality.

With both of these voice control devices, some of the commands are relevant to having a Fan and Drive Cable, which would be purchased separately.

My screen is blank, what should I do?

There is a process you can try at home to fix this that involves opening the FireBoard unit.

  1. Open the case of the FireBoard by unscrewing the four screws on the bottom of the unit with a Phillips screwdriver.
  2. Disconnect the battery. Note that the battery connector is very tight: grip by the plastic part of the connector, not the wires.
  3. With the battery disconnected, hold down both of the buttons on the front of the FireBoard.
  4. With both buttons held down, plug the battery back in. Continue to hold the buttons for 5 seconds, then release.
  5. After releasing the buttons, the “Read” LED should lficker for 8-12 seconds. The FireBoard should boot up and function as normal.
  6. Replace the screws and secure the case.
