TV-Lift Hack

Trying to hack my tv-lift into HomeAssistant

Background info for this project

This project started with me having a TV-Lift with a stupid RF-remote that cannot be replaced by my Logitech Harmony remote. I then watched Level1Techs video about the Sonoff RF-Bridge and thought that this was the solution to all of my problems. I proceeded to buy a Sonoff RF-Bridge, started the tutorial. As soon as I opened the device, I discovered that I had a new HW-revision. HW-hacking of this kind was way above my skill level. I got annoyed, and forgot about the whole thing. Until i stumbled across this Youtube video explaining the same process using the new HW-revision of the Sonoff bridge. Finally I would finish this project! It was first when I got to the point in the video where I was going to capture the commands from my remote that I discovered that RF is not RF. The Sonoff bridge operates at 433MHz as advertised. The only RF i knew at the time. The tv-lift remote operates at 2.4GHz. The manual specifies "RF-remote", so I guess it was also as advertised.

This left me back at square one whithout a plan, but enough built up anger at my tv-lift that I swore to make it work some how.

In the meantime, I had gotten better at HomeAssistant, and had started tinkering with ESP32. This is my new plan. I will try to control the tv-lift using ESPHome.

Requirements for the ESPHome based solution

  1. Will use ESPHome and an ESP32 NodeMCU board.
  2. The remote will not be modified.
  3. Board must attach to the tv-lift in paralell with the remote.
  4. Attachment of board must be non-destructive and possible to remove at a later stage.
