Can I make one device mirror another device?

Hi, @Sixoul
Here’s an example of a Rule to make the mirror effect:

Mirror behavior in routines running local

The engineering team mentioned the mirror functions can be achieved using the Rules API and the changes condition. It is different depending on the capability configuration to set the attribute value. For example, the Switch capability has two enum commands that don’t receive any arguments. In this case, we need to check the change to a specific value (“on”/“off”) and send the same value to the other device. This sample shows how we can mirror the switch events of a multi-component device that has a switch in two components (light and main), that’s also why only one deviceID is used. { "name":"Mirror switch events of main and light components", "actions":[ { "if":{ "changes":{ "equals":{ "left":{ …

In that case, the use case is with the Switch capability but you should be able to do it with switchLevel as well.

Here’s another example using the capability of “colorControl”:

Hi, @RJGill84 The colorControl capability is tricky, so, I created a sample, I just tested it and it worked on virtual devices that include it: { "name": "Changes - colorControl", "actions": [ { "if": { "changes": { "operand": { "device": { "devices": [ "device1-id" ], "component": "main", "capability": "colorControl", "attribute": "saturation" } } }, "then": [ { "command": { "devices": [ "device2-id" ], "commands": [ { "component": "main", "…
