Is it possible to define a notification across multiple sensors? E.g., something like "if sensor1 and sensor2 are down then send notification Y, otherwise if just sensor1 is down, send notification Z"
It seems notifications (or the triggers that send them) are only capable of looking at one sensor's value, not looking across multiple sensors.
Thanks

That Sensor Factory Sensor link is broken. Is it still available somewhere else, or is this answer no longer valid?

You can do this with a Sensor Factory Sensor there you would be able to define how the sensor goes into an error state with a custom formula. You would have to create the Sensor Factory Sensor with the channels from the sensors that you want to reference. It may be necessary to set up more than one depending on how you set up the formula.
