I want to let you in on a little secret. It all started when my solar panel inverter failed. The new inverter came with a wireless network and can be connected to the net and an app on my phone. So that's great & got me thinking about the new smart meter that also has an aerial. With some tips from chat. So I rang my electrical supplier and found I can view my power usage hourly, updated daily. Now I can see in real time what is using all our electricity and when. Yesterday was a good day. In the middle of the day a cloud must of came over. The green is power we bought. The orange is the left over power we did not use produced from the solar panels. If you have a smart meter this is what you can view online with your provider.
