It works the same way with channels. The channels are compared by the mandatory field name; if the channel name from the configuration file matches the channel name in the template, all unspecified values will be taken from the template. | It works the same way with channels.

In this case, we have described one my-device template, by which we have defined two different devices Device 1 and Device 2 with the same set of channels. | |||

Since Device 1 is on the local network, it is logical to set it a small timeout value to quickly determine the malfunction of the device. All other settings are taken from the template. | |||
Device 2 and the remote server, because for him, it is necessary to increase the timeout to not think the device is faulty if the delay of the package. What's more, for channel 2 here, we are redefining the polling interval to a larger one to reduce the load on the network. | |||
So, it is very convenient to use templates to describe a group of similar devices. | |||
