I'll be impressed if you can pick your fridge's consumption out of the overall import data.http:///newforum/extensions/Vanillacons/smilies/standard/bigsmile.gif" alt="

A plug-in energy meter is much more useful for measuring appliances.
Posted By: tonyI think BigData can see your fridge use but need second by second energy use record and extensive analysisUK smart meters provide data no more often than every 30minutes to the energy co. But every 10s to the householder, I went round turning things off to work out how much the fridge uses. My overnight usage seems higher than expected, more investigations to follow.
Posted By: tonysmart meters but they only record they don’t do anything smart like assisting you to save more.
Posted By: meI was surprised... but having the display of £ and p has saved 10-20% usage
Posted By: tonyWho pays for smart meters, individual customers or all of us ?Based on what I've unexpectedly saved so far, I'm very happy to pay for it in my bill. I expect to save a lot more if/when we get EV or HP.

Posted By: DamonHDYou can clearly see our fridge/freezer demand in my 15-minute Enphase data
Posted By: RobLOVO can give us daily kWh use, but they also magically manage to figure out what appliance types use what percentage of energy, averaged over a month. Quite impressive I think, it could show the importance of different things better than a kW display - I think you can pay for gadgets to do similar. Piccy below shows some of it, all I could fit on my screen in one go:

Posted By: CWattersI will switch when they can guarantee I will get a SMEETs 2 smart meter.
Posted By: djhI'm not interested in passing data over the Internet.I've been wondering about this as the reliability of meter data is so poor. I suspect the specification was written long before the Wi-Fi became pretty much ubiquitous and I wonder how many folk would be happy to have a HAN device that could upload data to the DCC via Wi-Fi. i.e. you plug it in, it talks to your meters over the HAN (Home Area Network) then uploads the data over Wi-Fi rather than relying on the WAN comms.
Posted By: WillInAberdeenThe vital next step is not for the meter to communicate with the IHD - rather it needs to communicate with the immersion heater and the ASHP and the towel rail to run them at the cheapest times.Making them talk to the immersion etc is way outside the scope of the SM, the variables immense and is just not feasible. In addition, the meters do not reliably know what the current half hour tariff is nor (and more importantly) accurately know what he time is.However, making the spec such that there is a defined API to access the data on the HAN is more than possible and, as pointed out recently, is actually required as part of the spec!
