In this and the next videos, I build a Home Automation system with Sonoff Switches, Wemos Mini PIR sensors, MQTT, Pi Zero, and Alexa. Without one line of coding.

Wireless mesh networks are fascinating because they adapt to changing situations and can bridge longer distances than point-to-point connections. Today we will have a look into the standard Zigbee mesh technology, learn its pros and cons, and compare it with Wi-Fi and LoraWAN networks. Mesh networks are a little anarchic, and maybe this is why they are fascinating for many free-thinking Makers. But is this true? To find this out, we will: - Compare mesh networks with star or “hub-n-spoke” networks - Look at the different roles in a mesh network - Look at the pros- and cons of a mesh structure - Enable a Raspberry Pi and a cheap USB dongle to act as a network coordinator - Find a way to chart the network for analysis automatically - Try out various network constellations and see if and how it adapts - Connect the network to Node-Red - And glimpse into other mesh networks I am a proud Patreon of GreatScott!, Electroboom, Electronoobs, EEVblog, and others.
