A:AnswerIt comes with the LED strip, power supply, and Zigbee radio. The strip has an adhesive backing, and the power cables a pretty long.
This kit must be paired to either a Sengled hub, or a home automation hub like Hubitat Elevation or SmartThings.
A:AnswerThe strips are driven by one power supply in a line. If you were good with a soldering iron you could do this but once you cut the strip you also cut off the connector to put the second strip in line.
A:AnswerNo, but you can use the SmartThings app to control or automate it. I’m using mine as kitchen cabinet lighting that automatically turns on when motion is detected.
A:AnswerIt isn't required but helps. Basic functions such as power and color cycle are avaliable without the hub but are limited. The hub allows you to dim and access more colors. Would definitely recommend going ahead and buying the hub as well.
