We use it to orchestrate agents, most of which, but not all, tunnel into VPN concentrators scattered across the globe to monitor and control remote devices. Admittedly ours is in the M2M IoT space for now (Digital Cinema) -- we don't deploy our own sensor network (yet) though our agent could broker that integration as well.
After toying with k8s, we realized just how much tinker time our current docker-n-script approach takes to optimize and scale optimally. We're close to moving to k8s after almost a year of on-again/off-again dev and I'm very excited to roll it out. Not as excited as DevOps, maybe, as it's going to lift a lot of weight off their shoulders.
TL;DR: IoT means different things in different industries.
