SmartThing smart wifi plug question

I’m new to IoT/IFTTT. I just picked up the Samsung - SmartThings Wi-Fi Smart Plug - White (GP-WOU019BBAWU) today. My plan is to have my Samsung Galaxy s10+ monitor its battery percentage level and turn on/off the wifi smart plug where the wireless charger is connected. I like to accomplish this without requiring any cloud account/connection setups. An app/trigger/tasker on the phone should connect to the plug through my WiFi router and turn the plug on/off. It’s even better if the phone can directly connect to the plug without the router (Bluetooth may be). I don’t need to turn the plug on/off from half way around the world - no need to control it from the cloud. Thanks
