Smart Home Notesby Julian H. StaceyThis is: http://www.berklix.com/~jhs/smart-home/Introduction:
Routers
When you select your telecom supplier, ask if you can get a
rebate instead of a bundled router,
if you supply your own router.
Various things are easier to configure, and with more
flexibility for eg remote control for alarm call out &
monitoring if you choose one with extended functionality. eg
in Germany: Deutsche Telekom offers cheap connection first
year to tempt new customers, the rebate subsidises buying a
router. The contract ties you for 2
years. Telekom offer a small range of their own routers, or buy your own in a shop or on
the web:
Old Cameras & Smart Phones
Old cameras with USB interfaces can work as net cameras. eg
even a really cheap camera bought maybe 10 years back in
Tesco, credit card size, except for lens, for all of ten
pounds, no screen, just 1 button, but it works as a USB
camera / net cam.
Old Android phones can work as cameras via wlan, though specific cams can be screwed to walls easier. (I haven't thought through security encryption issues yet.) Wikipedia on Protocols etc

Thoughts Of The Future
Aside from all the energy supply side generation options, the
other half is demand regulation. We'll want smart meters
linked to micro controllers to control individual devices,
& not just to On & Off. & very variable very
small time slice dynamic tariffs:
Eg when no wind & tidal & solar available, & the football half time on TV is on & all turn on their kettle in UK for tea coffee (but not in countries where they fetch more beer) is worst time to keep topping up electric car batteries, which should be feeding & selling back to the grid at premium rates. Domestic hot water Immersion heater tanks could heat to a lower temperature for half an hour, not just hotter all night as now.. Kettles could boil slower at peak demand, (but difficult as cheap devices, & control would cost significant extra manufacturing cost & space on kettle). In hot periods, if there's a few minutes of high demand, the air cons & Bitcoin miners could stop or slow, & domestic PC CPUs could run slow, but not lifts or equipment in hospital, or plane runway light, or dam control gates or most of all, nuke power stations that have powered off, but still consume power for cooling. On nights when no wind & tidal, houses & swimming pools could warm a bit less, all automatically. Only the super rich/ desperate who push the device over ride button could consume at old normal settings & they will pay at the higher tarif, whether society deems that 20% more, or 500% more ;-) It will be interesting to design. we will need to design international device id classification type non forgeable electronic certification, non patented, public standard for free interoperability between manufacturers. Engineers will need some support & decisions from politicians. Criminals will want to forge device classifications. One example: What classification will power meters declare for illegal marijuana growers (in underground concrete bunker & in the loft) . Best their UV lights go out occasionally too at peak demand, wont delay plant growth much. Some already get caught by power monitoring. What will their devices declare when there are Only smart meters, & no dumb meters allowed ? Smoke DetectorsDavid of Faraday 2022-04-01 mentioned what I heard as: Bosch Ferien 5000 0W or OW 868.3 MHz, allows up to ~40 units for a large building. Searching:
