Dear all,
Since I know some of you are experienced and knowledgeable about this, I’m just quickly asking here. I want to identify my biggest energy consumers—and do it properly.
What is more cost-effective and simpler?
Putting a plug-in energy meter on every outlet?
Or measuring in the distribution board? Is it even possible to measure consumption per individual circuit breaker with fine granularity there? Or not?
For example, there is the Shelley 3PM. I still don’t understand whether it can only measure total household consumption, individual circuits, or even more detailed information. Would additional modules be needed?
The reason I’m asking is that I already have several built-in appliances. I can’t easily access the outlets without removing the appliances. Therefore, a solution in the distribution board would be preferable, but only if it is technically feasible and not prohibitively expensive.
Thanks and best regards

I want to identify my biggest energy consumers and get it right from the start.When I think about topics like this, I always ask myself what I will actually do with the results. I still have to operate the dryer, washing machine, stove, and so on.
Sure, I’ll know how much the evening TV program costs in cents and euros, but will that make me watch less TV?
So, what is your goal once you have identified the biggest consumers, and what measures do you plan to take that justify the technical effort and costs involved?

This only really makes sense if you combine the measurement with an actuator right away to avoid leaving devices in standby mode or to temporarily switch off the router or access point. It’s annoying when, for example, the TV turns off at 11:00 PM on a Monday evening during vacation because you forgot to remove it.
That’s why you can basically forget about doing this in the kitchen. Sure, a coffee machine consumes power, but that doesn’t mean you’ll drink less coffee. Also, devices have become much better at standby mode over the past years. Often, it’s not even worth turning them off with an actuator because the actuator itself consumes energy 24/7.

To find out if the consumption of individual devices might not be correct.
If I subtract heating and hot water, we still use over 6,000 kWh/year. I consider that too much.
Okay, the electricity for the pumps of the heating and ventilation system is missing here, as the Vaillant system does not include these in its energy consumption.
My wife’s plant lamps – she herself had already bought remote-controlled smart plugs that can also measure consumption – only account for about 900 kWh (also quite a lot, but it can’t be the majority).
I suspect the cooling appliances (possibly using more energy than stated? or leaking?) or that the stove also draws some power while idle, or my home computer, switch, no idea.
At the moment, I’m working completely in the dark.

To find out if the consumption of individual devices might possibly be abnormal.Why not simply take a pragmatic approach and buy a plug-in power meter? Measure directly at the device and then check each device one by one.Similar topics
