A separate thread might be good...

My 240 load is 4Kw of electric heating cable that is installed outside. It provides ice melting and snow clearing for a stone walkway.

A lot of remote relay stuff assumes either 120 volt AC or that a neutral/white wire is available. Not the case for my load, 240 volts with no neutral at the connection box.

I do have the option of moving the control point to a new junction box next to the breaker panel, which gives me the neutral. But still must control a 240 volt load.

I would like to be able to control this load, and see the current status (on-off) from anywhere on the Internet. SInce I already have WiFi everywhere in the building, I was hoping for a device that had it all together.
