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.

#gitcheck.js This initializer checks plugin directories for git branches, and reports which branch is being loaded by the server.

I use npm link to serve up my plugins-in-progress for actionhero. I ask npm's preinstall hook to run npm link $PLUGIN so that the plugin will be in actionhero's node_modules dir when the main install happens.

It works very well for us, but when the gitflow is feverish I need to double check which branch I'm running in a given actionhero config.

I put this initializer at the projectRoot level, and it sweeps my plugins to report on git branches.
