Protocol
Wi-Fi
Wi-Fi devices connect over your existing wireless network. They are easy to set up and do not need a separate hub, but most rely on the manufacturer's cloud and tend to draw more power than mesh protocols.
Brands on this protocol
Wi-Fi is the most familiar protocol because every home already has it. A Wi-Fi smart device connects directly to your router, and a companion app or integration ties it back to Home Assistant.
Strengths
- No extra hub required for most devices.
- High bandwidth suits cameras, doorbells, and other high-data devices.
- Wide compatibility with consumer routers and mesh systems.
Trade-offs
- Cloud dependence is the norm. Many Wi-Fi devices stop working when the manufacturer’s servers are down, even for local actions.
- Power draw is high compared with Zigbee, Z-Wave, or Thread. Battery-powered Wi-Fi sensors typically last weeks, not years.
- Network congestion can become a problem in larger installs with many Wi-Fi devices on the same band.
When Wi-Fi makes sense
Selora installations use Wi-Fi for cameras, video doorbells, network audio devices, and selected presence and air-quality sensors where the bandwidth and refresh rate justify the trade-offs. For simple battery-powered sensors, a Zigbee or Thread alternative is usually a better fit.
