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"

`substitutions:
device_name: Schreibtisch
name: esp-schreibtisch
min_height: "75.1" # Min height + 0.1
max_height: "109.1" # Max height - 0.1

esphome:

platform: esp32
board: esp32dev
includes:
- desk_height_sensor.h

project:

Wake Desk by sending the "M" command

This will pull the current height after boot

on_boot:
priority: -10
then:
- button.press: button_m

wifi:
ssid: !secret wifi_ssid

Enable logging

logger:
level: DEBUG

level: VERBOSE # Makes uart stream available in esphome logstream

baud_rate: 0 # Disable logging over uart
