This + Etekcity ZAP remote controlled plugs x5 is like the cheapest smart plug combo.
I used the device handler code here: https://raw.githubusercontent.com/itsamti/Broadlink-RM-SmartThings-Alexa/master/Broadlink%20RM%20Bridge%20Switch%20LAN
To record EtekcityZAP remote controlled plugs, you need to click and hold the button for a second multiple times instead of holding the button the entire time.
When creating new devices, make sure you put the exact name (case sensitive) you used on the RM bridge WEBSITE as device IDs.
