36, I think. 9 are computing devices and peripherals: 3 laptops, 2 tablets, 2 phones, 1 wifi inkjet printer and 1 wifi laser printer. 6 are entertainment devices: 1 smart TV, 3 gaming consoles, 2 media players. 21 are home automation devices: 1 wifi-zwave-zigbee-leviton-lutron hub, 1 connected deadbolt lock, 2 connected garage door openers, 4 old Android phones that serve as IP security cameras, 5 connected smart bulbs, 4 connected power outlets, 1 connected thermostat, 1 Amazon Echo and 1 "plug PC" that runs a home automation server and backups. I have to run 3 routers to keep everything covered, and everything that can speak 5GHz instead of 2.4GHz does so just to keep the airwaves a bit less crowded. The network is a mess.
