*cough* home invasion events *cough*

We just gonna let them tie up Rupert's mom and only respond when she doesn't go to the bathroom or open a door?   Worse, what if they DON'T tie her up and just go merrily about the business of satisfying all of our occupancy tests?

<added>

What are some events that are passive for the occupant but might act as a trigger?  Off the top...

High decibel noise.
Window or door opening between x & y hours

On ebay right now trying to put together a kit of parts to make this all happen in an Arduino.

Passive Infra red - No problem
Doors / windows opening - no problem
Decibel count - Not sure at the moment.Decibel Count - no problem

Any more to add to the list?

I should add that the wirelesstag products can also work on doors, windows opening with either the reed switch or the motion detector.

As such they can be programmed to do something, IE set off the alarm, ping someone, if it happens outside or normal hours. I'm still trying to find a plug and play microphone sensor for noise/screams etc, but so far Arduino seems to be the way.

the problem with loud noise alarms and old people is the TV. I'm still deaf from Christmas.

ok - how about....

pressure pad to identify whether someone is sitting in their favourite seat... if the house is occupied but no one sits in that seat for x period then likely there's an issue (if very clever pressure paid will identify normal sitting or unconcious sitting - if a fitbit can do it I'm sure a pressure pad can, although dodgy if they're prone to dozing)

motion detector in places which will only be rummaged in by intruder like high cupboards or in drawer marked 'valuables'

detect TV or radio NOT playing something distinct they always listen to - normally theres at least one programme which is regular and never missed and would be reliable enough to trugger a phone call at least.

Gurtie that's brilliant.

If we use the motion detector thing from wirelesstags and simple put it in their wallet, purse, necklace, bracelet etc. We can ascertain if there is no movement.

Alternatively, put it in a drawer that contains some valuables and instruct the home owner. If ver you get burgled, tell them your cash is kept in drawer X (of course make sure some cash is kept in there) but otherwise never open this drawer on the sideboard. If that drawer is opened then you know there is a code red situation and we can script appropriate action to occur immediately.

(The site shows an example with a fridge opening, showing it is sensitive enough to detect small drawers, doors, cupboards opening etc)

Or a PIR in that drawer, wardrobe etc.

>I'm still deaf from Christmas.

HHH!

>brilliant

I'm convinced that a lot of what appears to be AI is just excellent combinations of if-then.

I think the high cupboard and/or top shelf of the wardrobe is a good idea. You could put a cam there and tell Mom it's there and she'd never go near it.

>decibel

Some of the older alarm systems had a "noise of glass breaking" sensor.

Bonus: A smoke alarm would trigger it, too.

> breaking glass

I was reading this earlier this evening. We're clearly thinking similarly.

I should have added that most standard wireless house alarm sensors seem to work on the 433mhz  frequency and as there is a receiver for arduino and it costs a couple of bucks, all standard alarm sensors should interface easily.

I appreciate it's not an "off the shelf" answer, but it's the route I am going atm and I feel pretty confident I can make it internet enabled.... Kit will be ordered soon, so we'll see

Yippeee,
Back in the th3core.... it was probably me... continued here:

No, we have a server problem. LM has contacted the host, I believe.

Rupert, did you see this Hubitat release?
