Yeah, I have a single 4b doing everything from openhab to shinobi to LoRA bridging, MQTT brokering, VPN termination, DNS, routing, pretty much anything where I need a Linux box to do a thing - we live off grid, so having a handy utility server that uses very little power is dead handy. Plans to get another, as some redundancy would be good and it strains transcoding video, but you can pile a surprising amount onto one.
