Not seeing all devices on network.

Recommended Posts

SKeating

Hello

I have just installed the agent on my QNAP and it is scanning my network. I have a 10.10.X.X network. The devices that receive an IP from the DHCP server are not showing up, only those devices that have a permanent IP. Is there something I need to do in the configuration to get all the devices to show up?

 

Thanks

I just installed the QNAP agent as well and my scan is seeing both DHCP and fixed IP devices other than my Ring Doorbell - it detected it but reports it offline.  I use my Ring app and all appears to be normal.  Other device drops (iPhone) seem accurate so far.  Was wondering if there is a problem with the Ring device - curiously - I can't seem to trace or "see" the ring device with my IP Scanner (which may back up what Domotz is telling me).  The Ring is connected via wireless network but is a hardwired doorbell.

The scan, on every single subnet (or VLANs) is limited to a /22 range (MASK 255.255.252.0) around the QNAP IP Address. This has been done to avoid too many broadcast messages on the network. Note that with any single subnet supported, you can monitor up to 1024 IP devices. And you can add multiple VLANs and Level 3 subnets.

 

My recommendation, if you don't need a Class B network, is to configure the network as Class C (or larger to /22) and have the devices you want to monitor in that range.

Is it possible that the Ring is behind a WiFi network extender (Layer 3 only)?

I have the same problem with my Domotz device.  It rarely detects my Ring Doorbell Pro as well as a few other devices.  Support has worked with me on this issue and concluded they would have to install custom firmware to make it work as "expected".  Or hardware isn't exactly the same but it brings up the question about the Domotz software ability to see all of the devices that are clearly online on a network.  I wasn't willing to accept the consequences of my install having custom firmware so I've just learned to live with it not accurately recognizing some of the devices on my network and I just use other tools when I want accurate current data about my network devices.  It is very disappointing that my Domotz hardware device is unreliable for some devices because it would be a very useful and powerful tool if it worked for all devices on our networks.
