We have just released a well requested feature, hiding of devices.
Many Z-Waves support multi channels. This means that one device may have several devices in Telldus Live! This is for instance in-wall receivers with dual relays, power strips and others. Sometimes you don't need all nodes a Z-Wave device may offer and those devices will then clutter the interface.
By hiding unused devices it is also possible to prevent controlling of sensitive devices by mistake.
A new api-call has been added, device/setIgnore. This works exactly the same as for sensors. Ignored devices are not returned by devices/list. Just as sensors/list there is now a parameter includeIgnored to retrieve all devices.
