# Infrared (IR)

## How to Send Multiple IR Commands with Delays?

Smart IR remotes, such as the LinknLink eRemote or eHub, can assist with app or voice control. But how can an IR remote handle setups that require multiple IR operations to be performed sequentially with controllable intervals?

For instance, if you want to switch your input to HDMI2, you might need to:

Turn ON the TV (15s)\
Press Up (2s)\
Press OK (2s)\
Press Right (2s)\
Press OK (2s) to select HDMI2 as the input

Here is a simple and effective way to set this up: 

1/ In LinknLink App, add a "General Scene"\
2/ Add actions\
3/ Click the "Timer" icon next to each action to set delay

You can refer to the [Tutorial Video](https://youtu.be/r2AEgaliXKY) for a better understanding:

   Click the grey buttons and follow the wizard to manually learn the lR codeusing your physical remote.
