Hi.. it will be great if ewelink will make like a 5-way power extension cord where each of the 5 plugs can be individually controlled via ewelink app & shows consumption (Amp, Watts,Voltage)..etc..
Note: not only this extension cord .. but also ewelink should be incorporated within all electrical devices of the world.. & this becomes a huge challenge for ewelink..
I made three of my own with a 4-Ch, wired into a PVC cable duct with 4 sockets embedded in mounting plates. It serves the purpose but demonstrates the need for such a product, albeit low priority.
Why only five‑fold? Let’s go all out, why not. Make it seven‑fold or even nine‑fold, with a suitably thick cable. Or give it a modular design so everyone can attach as many sockets as they need. That would be wonderful 
And they should throw in a rice‑cooking gadget while they’re at it.
