My guess would be that the topic will be the same for all, coming from this single tasmota device. If I was to add another PIR sensor, door sensor, or a button to this RF bridge. Well, I do not add anything to tasmota. The device is listening on RF 433MHz for any device, and I want to filter for messages that are relevant to me. Each sensor device will have a different value in Data, to identify it.
I think I am trying to achieve something similar to this post.
