I’ve got three sensors I want to take an average temperature of at that point (so their current readings). To give me a “house average” point, so I can then work with it.
I’ve made a new group for them (a subset of the main temperatures group). Now working on the average.
I assume I could just make a rule that iterates over that group, counts the number of items, adds them together and divide by the number and push it into a new item.
I guess I’m wondering if there’s a one line/item only way of doing it. Persistence is on at the higher temperature group (each reading goes into it’s own table).
