Motion sensors to turn on an outlet that powers a water pump

So I read through this Creating your first flow : Node-RED and was a bit lost, but thankfully your video Creating a flow - Node-RED Essentials - YouTube helped to fill in the blanks. I successfully created a couple flows, but now trying to figure out how to get my Sonoff Zigbee 3 Plus to work with node red. First need to install it on my Debian machine. Not finding much in the way of resources on that topic, but will continue researching. Currently checking out Getting started | Zigbee2MQTT . Also ran into a roadblock installing my coordinator. If any has time to weigh in on the topic I created I'd be obliged. HOW TO - Sonoff Zigbee 3.0 Dongle Plus on Debian running on HP2000 Thank you in advance!
