I am trying to use some simple/cheaper Electronic gadgets to monitor our home as well as work place in 24/7

I am an Electrical Engineer, served as a project manager in TATA STEEL Jamshedpur works for last 37 years. Other than my professional life, I was an Electronic hobbyist since my childhood. Now in my retired life, I do not want any regular kind of jobs, I want to be a freelancer technical adviser.
