I got version 3 finished. I have gone through a couple of different buttons trying to find the correct one for me.
The parts list I have used
button- Amico AC 660V 10A 40mm 1.6" Green Mushroom Head Momentary Push Button Switch 1 NO NC (you want a normally closed momentary button)
door sensor - Everspring Z-Wave Door/Window Sensor sm103 (way to big, will get another schlage)
cheap project box
blinking led - this was from a dummy surveillance camera enclosure i bought to enclose a raspi ir camera setup. from harbor freight.
battery connector for led.
The vera/vox combo still is the same as before. lights on for 3 minutes, an email, and my lovely Lemon (vox) telling me someone is here.
I like the piezo idea, but i am not sure what i need to do to incorporate it. Might give me a reason to break out the arduino and try figuring it out again.
Next step is graphics. Not sure what i will do, but with my twisted mind, most likely no one will want to use the button.
Other uses for this setup- this is portable so if you had someone home sick, injured, or elderly, this would work also as an attention button, or emergency button. Or as a remote light turner oner. I actually use it to turn lights on and off when outside. (3 minute delay)
Thanks for reading.
