The philosophy for everything from the ground up needs to be to design in the use of less power from the start - if a sensor reads temperature an fires the result over the network, keep the traffic down - will a reading every second do, oe once a minute or ten per hour.

We do not care now but if the 'IoT' grows ar the current rate for too long, we sure will.

Keep the payload small - do the processing at the origin and only send what data is needed to solve the problem, not several kb of padding. Run lines idle when there is nothing to do. Power down totally when we can be sure of not being needed.

As an example of how not to do it, consider the whole battery backed up fibre phone fails in a long power cut fiasco.

All that could have been avoided if the initial standard had had a 'power cut mode' from the beginning, where the whole thing shuts off until there is activity on the right laser wavelength for incoming traffic, and/or there is outbound data on the phone line. An emergancy handset phone pick up can be detected with very little idle current indeed.

Or Why is your WiFi on when everyone is in bed ? Does it need to be?

In a country with tens of millions of households, every negawatt* counts.

Data centres are big, but there are not that many of them. Households look small, but there are a great many of them - much as there are more insects by weight than mammals. 

Mike.

* negawatt - thing not using power at the moment because it is turned off ..

Agreed Mike, we should all connect a time clock on our routers and this would stop pinging noises in the middle of the night as well.  Win, win situation.

Other problem is that all photos sent to me clog up my computer memory and certainly should not be allowed to be stored in my cloud memory.  How can we delete received photos automatically after say a month?    Any idea??

I suppose it does if you have security cameras that are connected via your WiFi or if there's anything else that relies on the connection such as the monitoring gizmo connected to a friend's pacemaker that is also used to remotely adjust it as they sleep .

My phone is set to go into DND mode at 9pm every night and only my parents and my partner can bypass that i.e. messages or phone calls from them will get through but no one else. This minimises the pings and other noises that can suddenly wake me up in the middle of the night! 

Re photos and the amount of storage space they take up, strangely enough, one of my old blog posts  Getting Your Digital Self In Order... has seen a sudden surge in viewership over the last few months which makes me think that it's now becoming quite a hot topic!
