Interact home assistant with node network without entity

Hi,

I don’t know if this topic is already here… but I need help.

I want to Interact Home Assistant with node-red to turn siemens LOGO! devices on and off.

I already have the configuration between siemens and nodered, but I need a dummy device (entity) to be able to act on it.

I think that is where I should go, but I don’t know how to create an entity or if there is something easier.Captura
