-Attention: I only have one [RJ12 model](https://community-assets.home-assistant.io/original/4X/f/5/f/f5fc22327830c83a9d3d856b56f9bfc04d5047e7.jpeg) to test this
-but it's likely that other Maidsite controllers are supported as their serial protocol should be compatible.

 ## Usage
 
 ### What you need
 
 * ESPHome compatible microcontroller
-* depending on your model of desk controller
-    * cable with RJ12 connector (phone cable, RJ11 may also work)
-    * cable with RJ45 connector (network cable)
+* cable with RJ12 connector (phone cable, RJ11 may also work)

+Sometime the Desk Controller does not supply enough current, then simply disconnet the VCC pin and plug in a micro-usb/usb-c cable into your esp-board.
