Consider rooms A, B and C. Each room has a door that connects to the others (doors AB, BC and CA). Each room has a motion sensor and a light. I would like to turn on the light in a room if there is motion in that room or one of its doors has been opened.
Homey supports zones to aggregate sensors that will trigger automation to turn on lights. Unfortunately, as I understand it, a sensor can only be in one zone. In order to use zone activity to trigger my lights, each of my doors would need to be in the two zones that it connects.
Do I misunderstand (is there a way for a device to appear in multiple zones)?
What is the best way to solve this problem?
Any solution that I can think of would result in the creation of intermediate virtual devices that would aggregate triggers to turn on the light.
These all seem messier than just being able to place a door sensor on the threshold of two zones in each.
A device can only be in 1 zone. You can use the Virtual Devices app to add it multiple zones, by creating a VD and copying the state from the original device within a Flow.
Consider Homey as LEGO. Using standard elements you can build your own system. Adding additional elements makes an overview of the standard elements and finding the right elements for your solution more complex. So that is why solutions you can build using standard functions are unlikely to be implemented as a new standard function. But of course you can always request Athom for a product improvement.
I think the product could be enhanced in this regard. As far as requesting such, I understand that creating a demand for it in these forums is the mechanism for doing so.
