Thanks Ashok,
What SigmaDesigns is telling us is that zwave+ (500 series) devices are backwards compatible with regular zwave. So, based on that, my preference would be to future-proof my investment and obtain zwave+ devices instead of regular zwave.
However, in your experience, do zwave+ (500 series) devices work better or worse than their regular zwave counterparts? I understand, that some of the specific zwave+ functionality will not work out of the box with A+, like ota updates, etc
My preference also lies with Aeon Labs devices, as they have embedded power monitoring as well. And even if Almond+ may not be currently supporting certain capabilities, these products are mainstream enough that, i am sure, the support will come at some point in the very distant future, perhaps when 0.84 is released...
