Hi LeeS
Take it a step further. They provided an updated firmware that does accept the sensor. If I remember previous occasions , on a future firmware release, that capability will be removed.
Its not like the system always had the capability, it didn't. They pushed out a firmware and it does. Now they will more than likely removed it.
If I were them, in order to mitigate this confusion, would not have pushed out a firmware that does. Sure I like having it, but knowing its probably temporary , well ... eh
