Main router takes longer to change status to not_home

[walberjunior]

Hello, first I would like to thank you for your project.

I have the following configuration: Archer C7 as the main router and an Archer C2 with DHCP turned off.

When leaving home I'm always connected to C2, which when disconnecting gives me the status of not_home more accurate than C7. C7 takes an average of 3 or 4 minutes longer to change the status to not_home.

Both use the same configuration in settings.json, except for ap_name.

Any way to make the C7 more accurate on disconnect?

Hi @walberjunior. From the bits of log you've supplied I see that the device is disconnected because of a timeout. This means the device went out of range, and the router de-associates it after a certain amount of time. This amount of time is usually a few minutes, depending on your Wifi settings. This is different from when you actively disconnect the device (for example by turning off wifi on a phone): the device then disassociates itself, which is instant. Long story short: when a device leaves because it goes out of range, there's not much the detector can do about that. It relies on hostapd to signal that a device has left, which only happens after a bunch of timeouts.

I hope this explains it a bit. In this case I guess the C7 router has a wider (outside) range so it's usually the last one to still have signal and then time out?
