If you run Home Assistant and own a standing desk with a Jiecang-compatible controller, a new open source project called DeskUp Pro wants to bridge the two. Built around an ESP32-C6 or ESP32-S3 microcontroller, the device plugs directly into the desk's RJ11/RJ12 port, draws power from the connection itself, and joins your 2.4 GHz Wi-Fi network. From there it exposes up to 32 entities in Home Assistant, including height control, sensor readings, and preset positions, giving you full desk automation without sacrificing the original physical keypad.
The board ships pre-flashed with ESPHome firmware and includes a built-in web interface plus a REST API, so it works with any smart home platform that can make HTTP requests. Initial configuration happens over USB-C or Bluetooth. Voice control through Google Home and Alexa is supported as well, and the developer built the project specifically to automate standing reminders as a way to combat prolonged sitting. The underlying desk commands were community reverse-engineered, and confirmed working desks include the Maidesite Premium and Standard lines, Desktronic Home One, Boho Office Basic Line, and the IKEA Uppspel. One caveat: Maidesite removed the RJ12 port from Standard controllers manufactured after July 2025, and desk makers sometimes change internal electronics without updating model numbers, so compatibility is not guaranteed across all revisions.
The DeskUp Pro sells for $75 (€69) on Tindie, with the price dropping to $65 (€60) for multi-unit orders. If you would rather build your own, the GitHub repository provides wiring instructions, YAML configuration files, example dashboards, and automation templates, though the project is licensed for personal, non-commercial use only.
