 Head over to the [./pcb](./pcb) for the pcb.
 
-For the firmware, install [Tasmota](https://github.com/arendst/Tasmota) e.g. using their fancy fully browser-based installer, then check out the [./berry](./berry) folder.

+## Features 
+
+* just plain fan control (%), independent of any temperatures, no PID, no HVAC-Setup
+* sensors for the RPM-Value of each Fan
+* some debug-values exposed as sensors, e.G. networking-stuff or a reboot button
+
+See [screenshots](./img/) for details.
