If there was a local, and more importantly, dependable, web based weather service, that had up to the minute data for your location, I would agree.
Trouble is there isn't. I have a Met station close to me, but cannot access the live data.
I also think the IoT's potential is overstated and very little benefit to be had. And the security is going to be truly dreadful.
Actually, I think the big lesson from that is the potential value of weather forecasts to improving COP. Most of the hot water will be used in the morning in an average household, and not further required until the evening. Putting an inhibit on the unit until 10am and then working at max power would be a very effective strategy on that day - whereas if it was cold all day then the best strategy would be to run at lowish power rates intermittently throughout the day and leave the unit to defrost naturally in between. The whole Internet Of Things will actually make this quite easy to implement.
Trying to sort out how much I still have to do before I let my plasters in. Have no plumbing done as yet but wondering how much first fix needs done. House is a bungalow and all block walls not a stud in sight. I have 3 showers, a bath and basin with wall mounted taps so my thought is this is the only pipe that needs to go in now. How does this get done in plastic with no joints, do I end up with coils of pipe until later? BCO has already said he wants pipe work sandwiched in floor insulation but obviously I don't want plasters tramping over that constantly.
Am I missing something blindingly obvious?
