Hello,
I am experienced nodejs developer, and linux administrator, i can create your nodejs project for your raspberry pi.
On 1st phase, i will create mini bash script to install nodejs on debial, on your rasp. pi.
Then by wget i will download your script, build depencies and run.
On 2nd phase as i understood you need to interact on cylon js sensors ( i have taken a look at documentation of this framework), and i will publish data via mqtt. Also it will listen on update messages to reload node script. Reloading of script i can manage via forever script.
Contact me if interested
