I'm building my new house and I would like to have all my sockets to be flushed with the wall. If I use your Sonoff S20 Smart Socket than it will be protruding and would not look as good as Sonoff Touch switch.
Are you thinking of making built in sockets or at least modules which can fit into wall box? I'm interested in European Socket version. My wall box internal dimension is 78x78mm 60mm deep.
I want to have complete control over all sockets in my house (including power meter feature)
For me it means that I would need to purchase 150 such outlets. I think business case looks promising for Sonoff.
