I'm not happy with ZigBee: Only a single, flaky edge between two floors means one floor sometimes craps out and can't be talked to by the coordinator/home assistant. The WiFi devices (Shelly&Sonoff) are much better thanks to great WiFi (3 indoor APs, one outdoor). However, we have a few ZigBee remotes/portable buttons and sensors (motion and temperature/humidity), which are a great addition. I already know where to put another ZigBee router to finally make that floor reliable. But I can only do so once my SO&I agree on what fixture to put there, and that's complicated ;-) Maybe look at the nVidia Shield as a more privacy-friendly alternative to FireTV et al. (at least that's what Mozilla says). Sadly it's pretty expensive. Can't say anything about NVR. The remainder I can totally agree with. If I unplug my modem, only thing lost are weather report and mower bot control.
