How To Discover Devices With Room Alert Manager

The General Discovery Settings tab is shown below at defaults:

• In this tab, you may view and edit the Discovery Scan Interval.
  • This interval controls how frequently Room Alert Manager scans the network to discover devices, either automatically or manually.
  • The Discovery Scan Interval must be higher than the discovery timeout values saved in the Automatic Discovery and Manual Discovery tabs.

The Automatic Discovery Settings tab is shown below. All settings are set to default, except that we added an Excluded Network Adapter.

In this tab, you may view and edit the following settings:

• Enable Automatic Discovery
  • Automatic discovery is enabled by default. You may disable it in order to stop Room Alert Manager from automatically discovering devices on your network.
  • If you disable automatic discovery, any previously discovered devices will change to “Not Discovered” in Room Alert Manager’s Inventory list.
• IP Addresses Excluded from Automatic Discovery
  • You may enter any IP addresses that you want Room Alert Manager to skip when it scans your network.
• Network Adapters for Automatic Discovery
  • By default, Room Alert Manager looks for devices visible to each of its host computer’s enabled and connected network adapters. You can exclude adapters from discovery scans if you wish.
• Automatic Scan Timeout
  • This value determines how many seconds Room Alert Manager waits after a scan for a response from the device.
• Missed Automatic Scan Threshold
  • This value determines the number of scans it takes for Room Alert Manager to consider a previously discovered device as no longer discovered.
• Time until Undiscovered
  • Multiplying the missed scan interval by the missed scan threshold tells you how many seconds it takes Room Alert Manager to consider a previously discovered device as no longer discovered.

The Manual Discovery Settings tab is shown below. All settings are set to default, except that we added a manual scan on one IP address.

In this tab, you may view and edit the following settings:

• IP Addresses Included in Manual Discovery
  • This list displays any IP addresses that Room Alert Manager has been configured to scan over TCP Port 30718.
  • To stop Room Alert Manager from scanning an IP address, select the trash can icon beside it.
• Manual Scan Timeout
  • This value determines how many seconds Room Alert Manager waits after a scan for a response from the device.
• Missed Manual Scan Threshold
  • This value determines the number of scans it takes for Room Alert Manager to consider a previously discovered device as no longer discovered.
• Time until Undiscovered
  • Multiplying the missed scan interval by the missed scan threshold tells you how many seconds it takes Room Alert Manager to consider a previously discovered device as no longer discovered.

The Push Discovery Settings tab is shown below. All settings are set to default, with one device currently pushing its data to the software.

In this tab, you may view and edit the following settings:

• Devices Discovered by Push
  • This list displays any devices that have pushed sensor data to Room Alert Manager, along with the push interval configured on the device.
  • To remove a device from Push Discovery, click the ellipses beside it. You can then choose to Switch to Automatic Discovery or Manual Discovery.
    
  • If Room Alert Manager receives any additional sensor data pushes from the device, it will appear in this list again. (To prevent this, make sure the Push to Room Alert Manager feature has been disabled in the device’s web interface.)
• Missed Push Threshold
  • This value determines the number of missed pushes before Room Alert Manager considers a device as no longer discovered.
