HappiJac bed lift

What it does

HappiJac bed lifts are a popular off-the-shelf system. The HA integration is usually custom because the stock controller is not designed as a smart-home device.

Why it’s useful in a van

  • Reliable physical system with a clean “up/down” control goal
  • Great candidate for safety interlocks (limits, obstruction checks)

How to install

  • HappiJac bed lift system
  • A control interface you add (relay control + limit switch sensing)

Most setups: - Tap into the controller’s up/down inputs with dry-contact relays - Add limit switch sensing into ESPHome
