we change locks and check smoke detectors and put new batteries in them. 

If they implement using specific build modules/packages (e.g. curl, session support, etc.) they need to identify the dependence as part of the total 'deliverable' along with the source code, schema, etc.

Hi Amy, there are some stand alone modules you can set up.

I figure  it would take to run on solar and battery bank system $30k.

@Anthony SimboliYou can go to ASHI.org and search for a certified one, they passed a battery of tests to become certified and follow a code of ethicsPaul

Home Depot makes a $40 weed whacker that uses the same 18V battery I have in my power drill, so the frustration associated with maintaining it is minimal.I would second the wood chips, fake grass, and would also throw in pebbles or gravel.  

I have general lights but apparently, the emergency lights need to be connected to some sort of battery(I’m not an electrician) and piping in order for the lights to stay on in case of a power outage.

HI IS THERE SUCH A THING AS A WIRELESS BATTERY OPERATED HALWWAY LIIGHT WITH A MOTION SENSOR, THAT IS BRIGHT ENOUGH TO BE ABLE TO SEE AT NIGHT ON STAIRCASE?   

Don’t go with battery operated Security Cameras for your smart home setup.
