    First experiments with NodeMCU to publish the current settings of my adjustable height working desk to MQTT.
NodeMCU can be found here: https://github.com/nodemcu/nodemcu-firmware
Note that you'll need a current version with support for floats (which the ultrasonic sensor library utilizes), I'm using 0.9.5 2015-03-18 with float support myself.
Support for the HC-SR04 sensor in NodeMCU can be found here: https://github.com/sza2/node_hcsr04
I provided my slightly adjusted version which makes measuring a non-blocking afair, allowing for callbacks when the measurement completes.
