added optocoupler to trigger triac

fed sensor output to esp module.

hardware set up done. will change to esp-07 after fw ok to fit in esp to black box.

here is my simple html page:


additional new features:
enable/disable motion sensing
enable motion sensing on set time
on off lamp on set time
manual control on lamp
Time is taken from ntp server

Isn't a SSR that refuses to turn off because the load is to small a good reason to at least contemplate relays?
We can't always control the load.
Maybe my SSR is faulty, all i know is that it works ok once the load is more in range of what the SSR is designed for.

I've seen the inside of some cheap chinese one...so I'm not amased about. With good quality ones and a proper setup, contemplation of the relays it's a good thing in a Technology Museum
