Links to all parts and tools are on my website link in description, but For your convenience at you can pick up a kit with everything you need to make this device except for the extension cord part. I will leave a link in the description to different extension cord options to use with it.
 I don’t include the extension cord for 2 reasons: 
I ship worldwide yes i ship to your country
So you can choose any type of end you want
I don’t have to many available so if you want one do not wait because they could be gone.
I also have an assembled option where I basically do everything I show you in this video, so you can skip this whole process all you have to do is connect your extension cord ends and can start using it
There is also an option regardless of assembled or not where I can flash it with tasmota for you.
If you pick up a kit you can follow along with the videos. Again go to oh yea I have fast USA shipping.
