Just got done doing extensive testing, by uninstalling and reinstalling different versions of Axial Control / In ControlHA on my server trying to get the power fuction to show up on my Aeotec Smart Strip.
Version 5926 and older works, but 5936 and newer doesn't. When I am on 5926 I can see the option to grab the 4 outlets and manage them as both outlets and energy monitoring. On 5936 or newer, can grab the 4 outlets but no energy monitoring option. Believe in 5936 there was a minor change because that is when it asks me to upgrade my plugins.
This came to life because I had to blow away my server (OS reload) and started over and couldn't figure out how to monitor the outlets when I know before that I could. Educated guess is that in the older version when I created the outlets and energy monitors they worked because they were upgraded when installing newer versions of Axial Control.
