Smart Energy Monitors by protocol
How do these protocols differ? Show the pros and cons
Wi-Fi 2.4 GHz (most smart devices), 5 GHz (cameras)
Pros
- No hub; it joins the network you already have
- Enough bandwidth for live video and audio
- Widest choice of brands and the lowest entry prices
- Setup is usually an app and a few taps
Cons
- Power hungry; battery Wi-Fi sensors need frequent charging
- Many devices only support 2.4 GHz, which complicates setup on mixed-band routers
- Dozens of devices can overload consumer routers
- Many products depend on the maker's cloud and stop working if it shuts down
- No mesh between devices; range is whatever your router covers
Our take: Right for cameras, doorbells, and anything plugged in. Wrong for battery sensors, and a few dozen devices can overload a cheap router.
