Sonos remote control based on an ESP8266, a rotary encoder, MicroPython and Sonos HTTP API.

• Control playback and volume with one knob
  • Volume up/down on cw/ccw rotation of encoder
  • Toggle play/pause on single press
  • Next track on double press
  • Previous track on long press
• Activity LED on sent commands
• Configurable via provisioning file
• Syslog support for info/debug logging
• Implemented based on asyncio

• Wemos D1 Mini
• KY-040 rotary encoder breakout
• Existing and configured install of Sonos HTTP API (e.g. in a Docker container).
• 3d printed case & knob
• 2 x M3x10mm screws

The firmware files can be find in the src/ folder.

• If not already done, install Sonos HTTP API somewhere on your network. This is mandatory.
• Flash current version of MicroPython to the Wemos D1 Mini as described here
• Create a sonos_remote_config.py for your target network, room and pin assignment. An example is provided which assumes the following wiring for the rotary encoder:
  • CLK to D6 aka pin 12
  • DT to D7 aka pin 13
  • SW to D5 aka pin 14
• Copy main.py, sonos_remote_config.py and the whole lib/ folder to the Wemos D1 Mini. You can use ampy, rflash or similar to do this.
• Reset the board and test.

STLs for printing a case are provided in the stls/ folder.

Please note:

• case_bottom.stl needs support from the build plate
• case_top.stl needs to be flipped to lie flat, no supports needed
