Disclaimer: I´m from germany and my englisch isn´t very good ... Sorry

Hello. With help from @iMicknl i was able to get my desk smart. Wanted to share my setup so that others may have an easy way to smart-up their desks :)

Hardware

• CB28M1B-1 "Control-Box"
• HS13A-1 Control-Panel
• DIGITUS D-Sub 9 zu RJ45 Adapter -> https://www.amazon.de/gp/product/B00FIUO4VI/ref=ppx_yo_dt_b_asin_title_o01_s00?ie=UTF8&th=1
• ESP32-WROOM-32 -> https://www.amazon.de/gp/product/B074RGW2VQ/ref=ppx_yo_dt_b_asin_title_o02_s00?ie=UTF8&psc=1
• Some Wires -> https://www.amazon.de/gp/product/B07VCG5YC4/ref=ppx_yo_dt_b_asin_title_o07_s00?ie=UTF8&psc=1
• RJ45-Network-Cable
• USB-Power-Supply and Micro-USB-Cable (i´m sure everybody has some of these lying around somewhere)

Wiring

  Wake Desk by sending the "M" command

  This will pull the current height after boot
