Well that took me a while… anyway I got it working for my Etekcity WiFi plugs. It’s still pretty rough but I figured I’d put the first version out here for anybody.
You can add my repo as nicolaskline | smartthings | master and then tap “Update from repo” to get the Etekcity-plug handler.
OR… use the typical method of adding via the SmartThings classic IDE. You can copy my code and create a new device handler “from code” and paste it in.
You have to add each plug from the IDE. And after installing the devices, just go to the settings on the device, in your app, and put in your username and password from the VeSync app (on each plug, sorry). Then set the name of the plug to match exactly what you have in the VeSync app.
The refresh button is just to use if the plug gets out of sync with SmartThings (turned on manually and ST doesn’t know about it).
