I was able to add two of these devices with a little difficulty (possibly caused by the distance between the Almond+ and the device). However, I have not been able to add additional instances of this outlet. This may be caused by the fact that there are too many (31) devices connected to the Almond+.
Until I can troubleshoot the issue I'm having, I cannot confidently sign-off on these (but I do no think the issue is with the device). As soon as I know more, I'll add to this thread.
I've also included instructions for reference.
