As we all now know that our energy go up to £3,549 energy price cap. Question is - I think dynamic line measurement system (DLM) allow us to switched off router overnight (once per every night) will not trigger any DLM to save our cost of turned off router every nights to save £72 per year on electricity bill?

Can you elaborate on the arithmetic of this, ie., how have you calculated the £72 yearly cost saving?
As the "unit" tariff will vary dependant on provider, method of payment etc, best to quote "unit" (kWh) claimed savings.

[XGS_Is_On]

The £72 is the annual figure for running a router according to a Think Broadband article. Turning it off overnight for 8 hours will save £24 a year based on these numbers.

Essentially pointless given the price increase. Switching off the router and cancelling the broadband entirely won't touch the sides.

Turning the router off overnight should not trigger DLM.

How much energy standby is Zyxel router for a total of 9 hours overnight (without switched it off)?

My electricity fixed tariff rate (Scottish Power Exclusive Fixed April 2023 B2) are:

Price guaranteed until 30 Apr 2023

Unit rate 28.22p

Standing charge 22.74p

Exit fee £30.00

Tariff end date 30 Apr 2023

Monthly DD: £40

You are on a fixed rate. The price cap won't impact you until May 2023.

I heard it will go up £6,000 in May 2023 from my current £1,943 

[XGS_Is_On]

The price cap doesn't work like that. It's a cap on standing charges and cost per unit. Your bill doesn't automatically rise to meet the cap that number is for the average home.

On the current cap your bill will more than double, though. By the time your fix runs out I image your £40 a month for electricity will be over £100 and your gas will rise even more sharply.

Just make sure you give regular meter readings if you don't have a smart meter installed, so you are billed on actual usage not estimates

I am on smart meter. My last 12 months on electricity are £400

My router power use 2.5A, 12V = 30Watts

£134 = £11.16 per month

The maximum rating may be that, but its unlikely it uses more than 1/3 of that in the real world.

A lot of routers include a ton of overhead if it has USB ports, as they need to be able to push a couple of watts per port, plus the router and WiFi when actively hammered will use a lot more than idle.  Even just having an ethernet port plugged in and active can add I think about half a watt?

It wont use 30W, I have a UDM SE (a much larger more capable box with an SSD in it, IDS etc) and it uses 22-24W and when I push my 1GB net with it doing IDS etc it hits just shy of 30w.
I would expect it to be 10w or less, so the equiv of 2 bulbs and some use less power if you turn off the wifi at night.

Which model is it?

This: http://www.tpcdb.com/list.php?type=&query=Zyxel has some logged rates.

 I would consider a plug to give you readings as its quite interesting getting the costs of washing clothes etc, I have a bunch of wifi tasmota ones that log power usage for me and send me alerts via Home Assistant.

[Alex Atkin UK]

You also have to bear in mind that constantly power cycling the PSU will potentially age it faster, that could be another £25/year if you're really unlucky.

Adding devices to monitor power consumption, you're adding another couple of watts per device you do that on, so its only really worth it either temporarily to get a baseline power consumption figure for that device, or on high power devices.

Ever since we got a smart meter we relied on it to tell when the electric oven has reached temperature.  Although we still waste a ton of electricity because I didn't notice it had done so 15-30 minutes ago.  I really could do with a little PCB fitted to the oven to report over WiFi when the element it on or off, so I can have a script to let me know immediately, but I'm not comfortable making one myself.   We do primarily cook with the microwave though.

The plugs I use, use less than 0.5w.

[Alex Atkin UK]

Which is why they are redundant if you're trying to shave a few watts but very useful for heavy loads.

Its also hard to confirm that as power meters in my experience are only accurate down to a few watts.

You realise I am not the one trying to turn off my router?
I use them to turn off things that I dont want and they happen to be calibrated and measure power usage as well. I save well over the little power they use and get the function of switching devices off at the wall.
