IR control not working

by Jerry


Many devices connected to Caavo can be controlled directly and reliably using IP (internet protocol), BT (Bluetooth) or HDMI-CEC (Consumer Electronics Control) protocol.  However many devices can't use these methods (e.g. TV, cable box, TiVo, many BluRay players, etc) so Caavo resorts to using IR (infrared) control.  IR signals are digitally-coded pulses of infrared radiation to control functions such as power, volume, and channel changes.  These devices require a direct "line of sight" with an IR transmitter to work properly.  If the "line of sight" is changed/blocked, or the transmitter is moved out of alignment, IR control can become sporadic or stop working altogether.

If the device, or Caavo, is behind a closed cabinet door you will need to point an IR transmitter at the device in order to send a signal.

Things to check:

  • Make sure Caavo has a line-of-sight to device. If you are using an IR transmitter, check its connection to Caavo's IR port
  • Check that the transmitter wasn't knocked out of alignment. The transmitter should point at the sensor of the device you intend to control, not at Caavo.
  • If you are using the Caavo HDMI-IR cable, make sure the HDMI-IR cable is connected directly to the device (your TV or cable box, for example, not to Caavo) and that the transmitter is plugged in firmly to the HDMI-IR cable
  • If the device that doesn't have control is a TV, make sure the HDMI cable from Caavo is NOT plugged into the ARC port of the TV.
  • Try restarting the device and Caavo
  • Make sure the device being controlled has the latest firmware.  Many TVs are not always connected to the internet to receive updates.

To retest device control with Caavo, go to Settings> Devices> [device name]> Change Device

IR can be difficult to troubleshoot because it cannot be seen with the naked eye.  Try using a digital camera (your phone's camera should work) to "see" the Infrared signal blasting from the Caavo box as well as any attached emitters. The Caavo box has two emitters on the front and one on each side that will light up when issuing IR commands like Volume UP/Down.  This is also a good method to determine if your IR transmitter is actually sending a signal or not.
