My energy supplier is in the vanguard of the rush to introduce Smart tariffs where the energy cost varies during the day according to demand and surplus criteria. So when consumption is high, it can restrict use of high power gadgets, but can reward with low cost energy when there is surplus. Similar to the White Meter / Economy 7 tariff, but adjusting load every say half hour.
To achieve this we will need to have a Smart Meter to allow readings to be taken rapidly and remotely. My supplier already uses my meter in this way. Now we get to the bottom line. The company issues a tariff code to all registered customers via an App (or API) which then acts like the conductor of an orchestra. The App will act like Alexa in being able to turn off smart appliances to a schedule defined in the App so as to maximise use while minimising cost. Sounds like a good idea, and on windy or sunny days, you can actually be paid for electicity you do not use.
Seems to be the way to go, but unfortunately I have way to go before I can benefit. I need Smart Appliances connected to the internet of things. So far I have a Robovac that is compatible, but my central heating controller is the wrong type and needs to be replaced: even though I can control it oover the internet it speaks a different language. My fridge is dumb, as is my washing machine, and my brand new diswasher will all need to be replaced before I can join the elite. My lighting is also not intelligent and the API is not on speaking terms with my alexa. So any alexa controlled mood lighting will need to be replaced. Bye bye disco lighting.
So what interested me as a geek is now a closed door. Unless I fit our all my appliances with smart power switches like Nest or Hive and yet another wifi controller and I bet my Sky network will complain about being interferred with. Or my doorbell will ring every time the fridge switches off.
The final nail in the coffin is that I will need a Smart Phone to run the App. It is not compatible with my laptop, and my mobile phone only receives morse code. I do have a tablet somewhere but it was pretty useless when it worked, and is probably junk now or an antique. I found it impossible to use sensibly.
