I am trying to build a map that monitors switch up/down state using the Device Tree Small map property. When I drag certain groups of devices onto the map, all of the ping sensors for the devices in question are shown. But other groups show only a couple ping sensors or none at all. Is there a device or sensor property that I need to change in order for that device's ping sensor to show up? Also, as a follow up, is there a way to append the name of the device before the sensor's name?
Thanks in advance.
