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
