Good morning everyone,
I wanted to ask what your house’s electricity consumption is at night when everything is quiet and sleeping, so what is running continuously?
We have a newly built house, moved in summer 2019. Our building services include underfloor heating (air-to-water heat pump), controlled mechanical ventilation (runs at full power 3 times a day for 2 hours each, then reduced), a photovoltaic system, and otherwise the usual nighttime appliances (phone charger plugged into USB outlet, e-bikes charging occasionally, 2 TVs on standby, Alexas on standby, etc.).
At night, we have a continuous consumption of about 232W (with ventilation running at reduced power and when the heat pump is not producing). I can see this in the app for the photovoltaic system. From 0:00 to 6:30 a.m. we consume about 2.8 kWh.
How about you?
Best regards

Sorry, but this is not normal. I also have KNX and a server, but the latter uses 50W, not 350W. Just as an example. Is that some old, discarded device consuming so much power? Investing in efficient components really helps a lot.
What is running there that constantly draws 350W?!

As a single occupant, I already consider myself a heavy user with around 3,000 kWh. This includes a home office with two computers and monitors, a large waterbed, and a lot of cooking.

What’s running there that constantly pulls 350W?! This might sound a bit odd, but I don’t think you can compare your server with mine. A server using 50W can’t really have significant computing power, but mine does. It has 4 GPUs installed (not high-end, though), and everyone at home has a VM with GPU passthrough assigned, plus KVM for mouse and keyboard. In addition, it serves as a data server (ZSF-Z2 with 12 drives), TV server, and much more. Using so-called efficient components doesn’t help here because they already are efficient. The power consumption simply reflects the amount of hardware packed into this server.

As a single user, I already feel like a high consumer at about 3,000 kWh per year. But that includes a home office with two computers and monitors, a large waterbed, and a lot of cooking. Please don’t generalize; I don’t want to argue about it—it is what it is. The technology without air conditioning, controlled ventilation, interior and exterior lighting (about 20-25 fixtures at 3-5W each), garden pump, etc., simply accounts for roughly 40% of the total consumption. I am okay with that and can live with it.

Would you like to explain what the VMs with GPU passthrough are used for?1x Kodi media center, 3x regular desktop PCs (GPU server -> HDMI to dual RJ45 -> dual RJ45 to HDMI -> monitor in the room where you want to work, plus mouse and keyboard). The remaining VMs are a data server, audio server for AirPlay, web server for home automation, CAD VM, to name just a few.

The technical equipment without air conditioning, mechanical ventilation with heat recovery, indoor and outdoor lighting (about 20-25 units at 3-5W each), garden pump, etc. simply consumes about 40% of the total energy use. I think that’s okay and I can live with it. If you can live with that, it’s fine. Still, you have some major electricity consumers causing that level of power usage. 4,500 kWh annually just for “technical equipment”? And it’s not even particularly advanced technology. Using 12 kWh per day only for servers and related devices is quite a lot. If everything is running 24/7 (and it shouldn’t be for example the data server, TV server, virtual machines, etc. – or are you all online 24/7?), that’s over 500 watts constant load. Impressive!
And even more so, what you consume for everything else – 6,500 kWh.
Sorry, but I just don’t understand how it’s possible to use so much electricity.
