Agree... I've scolded Jordan at Atlas-Sci on that... 🙂 . Just kidding. This node is good and sorely needed. I can only offer suggestions from my personal experience working with the Atlas stuff, my kludges and shortcuts.. The seasoned programmers here will really be of help with conventions and best practices.

One suggestion.... I put up a quick announcement of this node because 1. you're too modest and 2. lots of people have continually asked me about developing nodes / flows. That would be a great thread to illicit opinions/suggestions from the really seasoned developers/users here.

> Folks, I want to recognize MaddyP for releasing his initial version of the node-red-contrib-ezo node for comminicating with Atlas-Scientific EZO Sensors, Devices and Circuits. I've tested it on Temp, pH and EC and it works as intended. I'll continue my testing on some of the more difficult devices (EZO-FLO, EZO-PMP, EZO-HUM). His node is slick and has some time saving features included (automatic default i2c address assignment and delay based on EZO device type). If you've followed his project…
