Harmony One remote won't input channels very well
Most DirecTV receivers are able to be controlled with IR (infrared) or RF (Radio Frequency) signals. DirecTV receivers are usually set to be controlled by RF.
To control a DirecTV PVR / Satellite, it needs to be set to respond to an IR Remote:
1. On the original DirecTV remote press the Menu button
2. From the Menu press Select on Settings
3. Select Remote from the left menu
4. Press Select on the IR/RF Setup button
5. Use the Up or Down arrows to change from RF to IR
6. Press Select to save
Note: Some models of DirecTV may have different steps to enable IR. You may need to refer to your user manual
Harmony Remotes only control IR signals. so this is not the issue. The Harmony Remote should control the tv. the original remotr needs to be tested for IR or RF.
The device we are working on that is not being controlled by the Harmony Remote could be operating on RF (Radio Frequency) signals. Harmony Remote can only control the devices that operate on IR (Infrared) signals. Most devices that work on RF signals can be changed to operate on IR signals, and this usually could be done by changing the remote control command mode to IR from RF.
Please follow the steps listed below to test to see if the device is being operated on RF or IR signal:
1- We need to use the original remote for that device to complete this task
2- Using your hand or a thick and wide object (wall, pillow, book...), cover the top part of the original remote. In other words block the direct positioning between the original remote and the device.
3- After you cover the top part of the original remote (or used an alternate way to block the direct communication of the original remote and the device), try pressing the buttons on the original remote to see if it can still send commands that can be received by the original remote. You can try powering on/off your device using the original remote when the original remote is being blocked by your hand or another object.
4- If you still can control the device using the original remote without a point of sight, your device is being operated on RF signals. If you cannot control the device without a point of sight, then it is IR operated.
5- If the device is RF operated, please change the command receiving mode to IR rather than RF and test the Harmony Remote.
6- If the device is IR operated, please contact us again by replying to this email and let us know if none of the commands or some certain commands are not working for that device.
You can usually find the information on how to switch the device to be operated on IR signals rather than RF signals, through the user manual for your device, or by contacting technical support of the manufacturer for that device, or even sometimes reaching the information simply by doing a basic research over the internet.
