Does anyone know how to connect etekcity zap remote outlet switch to smart things hub
You probably can not connect the two, assuming the Etekcity Zap Outlets are the style that uses 433MHz RF for remote operation. On the back on my box of three of these outlets, there is a Technical Data list. Mine list “Transmission Frequency” as 433.92MHz. This is not supported by SmartThings directly.
The SmartThings hub expects Z-Wave or Zigbee devices. Some other WiFi/LAN-Connected devices can work as well, but it depends on the manufacturers to build those integrations.
If you search through these forums, you will also find some user-created methods to control the Etekcity outlets using “bridge” devices.
