RAYN RPS sensor not showing light levels in zone screens.

Issue

A RAYN Photo Sensor shows up in Settings that it needs a zone, but the home page of the zone and the sensor page does not show any data.

Syracadia has 2 modes of Display: Lux and ppfd (default).

In 2.2+ go to Settings / Preferences / Special Tab and in 2.1 and below go to Settings / Preferences / Special / Tab
Select LUX mode if you are going to view levels in Lux. If you want levels to be viewed in ppfd do not select LUX mode.
When you bind the sensors, you get 2 choices for each sensor: PPFD or Lux. You also need to make sure you have the one bound that you prefer to view levels in. You can have both bound, you will just see levels from one at at time depending on the state of the Lux mode button in Settings.
