Worked with the WD500Z-1 tonight more as I was dealing with Rules. Discovered the following issue which may or may not have been around before:
Changes at the switch itself are not detected by the Almond+.
Ex: Changing the switch to On, at the switch, does not register as any change in the state OR dimmer value at the Almond+. Turning if Off also does not get detected.
However, the switch responds to whatever settings the Almond+ sends to it. I was trying to set up 2 Rules such that when the switch was turned on (actually set to have a Dimmer value of 99%, since it never gets read or set at 100%) it would turn off a GE Link bulb. The other rule was to turn it off. These rules work fine if I do it all through the Almond+ or the app.
Just to check, I tried this with all 4 of my switches and none of the changes made physically at the switch are showing in Almond+.
