Doorbell with iOS alert
« on: August 29, 2019, 09:19:41 pm »
I need a new doorbell since next door got the same one as us and their front door bell,ouch rings our door bell. But I want one with iOS connectivity so that I get an alert when someone comes to the door. I’m not bothered about a camera and I’m particularly keen to avoid 3rd party server solutions.

The question is, Kim or anyone else, what have you got? Is it good? Is it commercially available or am I going to that to go home brew?

FWIW check your doorbell doesn't have a way to change its ID.  Probably some jumpers or DIP switches or something in the battery compartment of both parts.

Ours is extremely homebrew, and is part of a complex interconnected system with a squillion other non-doorbell features[1] (and at least one major bug I haven't been able to work around satisfactorily), represents a huge number of Kim-hours of work, a four-figure hardware cost, and wouldn't be much use unless you're already heavily invested in IRC[2] as a user interface.

But more generally, this is the sort of thing Arduinos are good at.  There seem to be various solutions to generating push notifications from an internet-connected Arduino, although the first three I clicked on seem to involve some third-party service that I've never heard of.  You could always do something standards-based like send an email, or low-tech and real time like a phone call[3].


[1] Everything from a gentle message if the computer thinks someone has fallen asleep in the bath, to re-enacting the Nostromo's self-destruct sequence when the fire alarm goes off, via telling you what it was you came upstairs for.
[2] Mainly this shows the age of our original system, but the great thing about having missed out on the cloud computing IoT revolution is that it all still works without an internet connection.  You can still just about get an IRC client for smartphones with a working highlight function.
[3] Back in the days when SMSes could take a several of minutes to be delivered, I used to have a Nokia wired to the Fiat Of The Apocalypse's alarm system via a PIC.  It would generate the appropriate AT command string to attempt to make a HSCSD modem call to my phone when the alarm went off (at which point I'd recognise the number and immediately reject the call).  I thought this was pretty clever until I saw Postman Piers's version based on a relay shorting one of the speed-dial buttons on a much older and less impressive Nokia.

I could fall back on IfTTT but that would fail the 3PS criteria.

If I was going to go old skool then I could rig something with relays and a bastardised mechanical digit regenerator, but it would take an age to find the parts and I’d have to build a 50v power supply.

I’ll probably look at a Wi-Fi connected Arduino or RaspPi, because, as OTS IoT kit suppliers are all obsessed with using their own servers to provide a service at a cost.

Push notifications on iOS pretty much require a third party server of some kind or another, unless you’re going to homebrew your own push server and receiver app.

I use my Arlo for free – the camera on the driveway activates when there's motion and triggers the one in the porch, so I get a notification and a video of what they've been up to along with a mugshot. I'm not sure I'd put more effort into a doorbell, when we had an actual doorbell that worked and I was at home, it's was a rarity to get there before the ringer was at the bottom of the drive and hopping back into the van to speed away.

This is true.  Not sure if it's always been this way, or the behaviour has evolved alongside the rise of mobile phones (people don't let a phone ring for longer than it takes to get one out of your pocket and answer it these days - if your hands are dirty or the phone's in another room, you're unlikely to make it in time).

Our doorbell plays a 10 second sample of Rod Hull and his finest drama students[1].  If I'm sitting at my desk and not entangled by headphones or anything, I can just about get to the front door within a second or so of it stopping playing.  I then have to get some keys and open the door, to typically find the ringer in the process of walking away having given up.
