Alfawise SJ-7 (Essential oil diffuser)

alt text

Updated for ESPHOME 2025.2.0 and later (2025-03-04)

https://esphome.io/guides/contributing#a-note-about-custom-components

Working

  • All essential oil diffuser related controls (ON/OFF; LOW/HIGH; Timer 1H/3H/6H).
  • Lava lamp lighting activation, fast/slow color change, I can add stop color change button if needed.
  • OTA upgrade.

Not Working

  • Use the light like a classic bulb (just on of off and choose a color).

Installation

Flashing

For flashing, you have to solder wires like this:

alt text Use U0TXD, U0RXD, GND (and VCC if you dont want to use the diffuser power supply).

Make sure to ground GPIO0 during boot.

You can use the ESPHome add-on from Home Assistant Community Add-ons

Original firmware

I have put a backup of the original firmware, and I also modified the AMA HOME APK but only for reconnect the original firmware to Wifi, ssg360 seems down.
