2.4/5GHz Network Set-Ups

Your eSphere sensor connects to your home network over the 2.4 GHz Wi-Fi band — by design. 2.4 GHz offers better range and wall penetration than 5 GHz, so it's the ideal choice for a sensor that needs to stay reliably connected throughout your home.

Your phone, meanwhile, will typically hop onto the faster 5 GHz band whenever it's available. That's completely normal and expected.

No. The sensor doesn't track your phone by which Wi-Fi band it's using — it detects your phone's presence on your home network. As long as your phone and the sensor are on the same home network, the sensor will detect it regardless of band.

The HC0100 is designed and tested on networks with a single, combined name for both bands. If your router supports this, we strongly recommend using it.

That said, most routers that show two separate names — for example HomeWiFi_24g and HomeWiFi_5g — still treat both as part of the same underlying home network. In those cases your phone and sensor can usually still see each other, and presence detection works. Because it's not a setup we validate against, we can't guarantee consistent behaviour across every router that uses split names.

A small number of home network setups can cause issues:

• Guest network — if your phone is on your router's guest network instead of your main home network, the sensor can't detect it. Keep your phone on your main network.
• IoT network with device isolation — some routers offer a dedicated IoT network for smart-home devices. These often block devices from talking to each other, which stops the sensor from working. Keep the sensor on your main network instead.
• Managed or office-grade equipment — if your home uses enterprise-grade networking configured by an IT professional, extra network separation may affect the sensor. Check with your network administrator if you're unsure.

When adding a visitor using the QR-code feature, your phone (the primary user) must be connected to the same Wi-Fi network name as the sensor when you generate the code. The visitor scanning it doesn't have that restriction — they just need to be on your home network in some form. Once they're added, you and your visitor can connect to any band and will keep being detected normally.

If the sensor is having trouble detecting devices, confirm:

• Your phone is on your main home network — not the guest network.
• The sensor is on your main home network — not an IoT or guest network.
• Your router does not have device isolation or client isolation enabled.
