About the Smart Plug category

The U-tec Smart Plug upgrades your traditional appliances to smart devices. We value your feedback, please leave your comments below.

Can you give some insight on how the groups work, like should all smart plugs be in the same group for the mesh to work?
How do you connect 1 plug to the next?

I have been using the Smart Plug on my room lamps and have noticed that I must set the on/off times one hour ahead of what I want it to work. Is that normal? Could it be because we are in Daylight Savings? If so, why? If not, what is going on?
Thank you!
