@Gonz0,

Hmm, there should be options to add a static route. I  believe that this feature may require each node on the network to be compatible. Have all of your Deco's updated to the most recent version, or do you have any non-X20 nodes on your network?

Also, are you able to try and configure the network from another device? It may be that a setting for the device itself is preventing your Deco app from properly communicating with your network.

I would also recommend checking to ensure that all of your Nodes are being seen as connected by the Deco App, if not, try rebooting your Deco network.

You may also check to may try seeing if you can access your Deco network from the app if you have your cellular connection disabled, as this will prevent the networks from automatically switching.

For documentation, our teams are just beginning to roll our official documentation for the features. They are only available on a select few pages thus far, such as the X60. However, the guide does apply to the Deco App as a whole and should prove useful to you: Deco App 3.0 User Guide
