I have a bunch of the WD500Zs working properly in Scenes, Rules, and individually. One thing I have noted is that they do not seem to notify the Almond when they are manually pressed. Ex: Switch is off, you turn it on with app/rule/whatever, it will turn on. You MANUALLY press the switch to turn it off... Almond will not know it is off. This seems to be with the switches themselves. I have contacted Linear (a couple times) asking about this and gotten no response. Securifi went to a lot of effort looking into this with me, we were even checking the Z-Wave logs, but it shows no messages come in with manual presses.
