List the normal actions

Write down power, volume, source selection and the streaming service you usually open. Identify which remote currently handles each. Remove unused accessories from the routine, but keep original remotes available for setup and troubleshooting.

Test shared control carefully

Some connected devices can control each other through supported features such as HDMI-CEC. Names and behaviour vary, so check the manuals and change one setting at a time. Unexpected power-on behaviour is a reason to review the arrangement, not enable every option.

Create a simple home for them

Use one tray or accessible spot and label confusing controls without covering sensors. Check battery orientation and condition when a remote behaves inconsistently. If trying a universal model, verify support for the exact devices and any activities that require more than basic infrared commands.
