Can I switch another actuator with the status of an actuator?

In principle, the status of an actuator cannot be used as a trigger in the HOMEPILOT App.

Google Assistant offers a practical option for this application, at least for lighting, which we describe in the following steps.

Our application should switch on a floor lamp in the living room when the light in the living room is switched on. It doesn't matter whether the light in the living room is switched on at the light switch, by app or by voice command. Whenever the light is switched on, the floor lamp is also switched on.

The devices that you want to switch together must be assigned to a room. It does not have to be the same room for all devices, but devices that are not assigned to a room cannot be used.
Now click on Automations at the bottom center and add a new automation. "Household" must be selected here.
Give the automation a name and add a trigger. "When a device does something" is the appropriate trigger type.
Select the device whose status you want to react to. In our example, it is the living room light. Specify the status to which you want to react, i.e. light on or off. You can even add a condition if required.
Click on "Add trigger" and then define the sequence. To control another smart home device, select "Set smart home device" and then search for the device you want to control. You can even trigger routines that you have already created in the HOMEPILOT App. You can find them at the bottom under Ambience
