I don’t know who developed this binding but I have several HS105 smart wifi plug minis using the binding and it works great so THANK YOU! to developer!
On add-ons page here it says the HS300 is not supported yet
Any plans to add to binding? I’m going to buy one anyhow because I need a power strip, it has 3 usb charging ports also and individual outlets in the power strip can be controlled and monitored via tp-link app. It isn’t cheap however. Here in the states at big box electronics store $80
