IoT is still expanding steadily; the hype peddlers and fad chasers have largely ignored it because there's no bubble for them to cash in on. Smart TVs, internet enabled appliances, robot vacuums, Alexa devices, Phillips Hue lighting, smart thermostats, etc. are all IoT.
The industrial IoT market is still expanding too but ordinary developers wouldn't be able to observe it unless they work in that niche specifically.
