Turn TV automatically ON if you select a channel

Tutorials & Examples Solutions
1

Hi,

I control my TV 99% of the time via voice assistant and always was annoyed that I need to issue two commands:

  1. Turn TV on
  2. Select the correct channel I want to watch

Therefore I created the rule below to automatically turn on the TV once the channel items receives a command. Once this rule is setup I only need to choose a specific channel and TV will automatically turn on and switch to the correct channel
Tested with OH4.0.4 & LG WebOS binding

Prerequisite:

  • Disable auto-update of power item via meta-data
  • Power item as switch
  • Channel item as string

Steps to do:

  1. Copy rule to your system
  2. Replace power & channel items within the rule triggers with your specific items
  3. Open the blockly rule and replace power & channel items at top with your specific items
  4. Have fun
