That's very odd. In general if a switch functions from the device page, and has been added to the Amazon Echo Skill app (in Hubitat), it should be controllable by Alexa. Could you confirm that it has been added to the Amazon Echo Skill?
Also, when you added the Zooz dual plug, it should have created two child switches corresponding to the Left and Right outlets.
Can you confirm that you added the two child switches to the Amazon Echo Skill? And not the parent device?
yes it worked for a short while then started hanging up even in HE
ahh I did not see that and that is probably my problem I did not change the security when
I included the plug
I do have the c7 and i just got it 2 days ago ran the update. I will try to exclude and re include without the security
