This is my attempt to reverse engineer AlzaErgo Table ET1 NewGen standing desk and add wi-fi functionality using something like Wemos D1/ESP8266.
The work is in progress.
Controls height of the desk, show the current height on display, has memory for 3 positions, you can set min/max height, etc.
Contains the PowerSupply Unit, controls the motors and, gets commands from the Control Panel.
The control box has a RJ-45 port. It seems like all 8 pins are being used but the provided Control Panel is only using 5 of them and does not wire the rest at all.
The wiring of the RJ45 port is as follows:
- D-TX (green wire)
- D-RX (brown wire)
- unused
- KEY-1 (white wire)
- G (red wire)
- unused
- unused
- +5V (yellow wire)
On the Control Panel side it looks like this:
