Smart Sprinklers and Timers by protocol
How do these protocols differ? Show the pros and cons
Zigbee 2.4 GHz (IEEE 802.15.4)
Pros
- Sensors and buttons are among the cheapest on the market
- Huge catalog from Aqara, IKEA, Philips Hue, Sonoff, Third Reality, and others
- Mains-powered devices act as routers and strengthen the mesh
- Coin-cell battery devices run for a year or more
- Works fully local with Home Assistant (ZHA or Zigbee2MQTT)
Cons
- Shares the 2.4 GHz band with Wi-Fi, so channel planning matters
- Some brands bend the spec; Aqara devices can drop off third-party routers
- Needs a coordinator (hub or USB stick)
- Brand hubs like Hue only accept their own approved devices
- Bulbs used as repeaters break the mesh when someone flips the wall switch
Our take: The budget king for sensors and bulbs. Pair it with a good coordinator and plenty of plug-in repeaters and it's rock solid.
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.
