How to Control Your Regular TV via IR and Zigbee

Hi everyone, I wanted to share my recent project on integrating my regular TV into my smart home setup. It was a fun challenge, and I thought I’d walk you through how I did it in case anyone else is looking to do something similar!

The Goal:
I wanted to control my TV’s power on/off functionality using my existing smart home ecosystem. My TV doesn’t have built-in smart features, so I knew I’d need some additional hardware to make this happen.

Hardware Needed:

  1. IR Remote: I went with a Xiaomi Mi Smart IR Remote. It’s compatible with Zigbee and has a wide range of supported devices.
  2. Zigbee Socket: I used the TP-Link Kasa Smart Plug (HS100). It’s reliable and integrates seamlessly with Zigbee.
  3. IR Blaster: This is crucial for sending the IR signals to the TV.

Setup Steps:

  1. Pairing the Devices: First, I paired both the IR remote and the Zigbee socket with my Zigbee hub. This was straightforward using the manufacturer’s app.
  2. Recording IR Commands: Using the Xiaomi app, I recorded the IR commands for turning the TV on and off. This involved pointing the IR blaster at the TV and sending the necessary signals.
  3. Creating Automation Rules: In my smart home platform, I set up two automation scripts:
    • One to turn the TV on by switching the Zigbee socket on and sending the IR on command.
    • Another to turn the TV off by switching the socket off and sending the IR off command.
  4. Testing: After setting everything up, I tested the system thoroughly. Initially, there were some hiccups with the IR signals not being received consistently, but adjusting the placement of the IR blaster solved that.

Additional Tips:

  • Power Monitoring: I also set up a binary sensor to monitor the TV’s power state based on the Zigbee socket’s status. This helps in creating more complex automations, like turning on the lights when the TV is on.
  • Voice Integration: I integrated this setup with my voice assistant so I can now say, “Hey [Assistant], turn on the TV” and it works perfectly!

Challenges Faced:

  • Signal Interference: The IR signals weren’t being received reliably at first. Moving the IR blaster closer to the TV solved this issue.
  • Script Logic: Getting the automation scripts right took some trial and error, but once everything was in place, it worked like a charm.

Final Thoughts:
This project was a great way to enhance my smart home setup without needing to invest in a new TV. It’s incredibly satisfying to use my existing devices to control something as essential as my TV. If anyone has questions or needs help setting something similar up, feel free to reach out!

Happy automating! :rocket:
