    I saw this brand name mentioned recently and having read up on them I think a couple of these in the house could be quite handy. Probably save more than running a timer for instance.

    Are these the go to devices or are there alternatives or cheaper products?

    Also any other energy saving tips and gadgets would be appreciated.

    Hi,

    Yes, I know Energenie. Nice people IIRC, think that I last saw them at PHEX and may see them there again next week.

    I still think you'd likely be better off with my product (if it's the rad valve element you're referring to), given complexity and cost. Trying not to self-promote here...

    As Damon asks, which Energenie product are you asking about?

    I looked at their smart plug but decided a TP-Link HS110 was better for me.

    Sorry I should have been specific. One of the standby plugs and remotes. For the TV off etc when you can't reach the sockets

    Always assuming the plug takes less power than the TV on standby :devil:

    If you have a relatively standard cable TV box they pull nearly 20W in 'standby' (really really should be clamped down on, but you rcable company doesn't care as they aren't paying the bill). I can't imagine that one of the decent standby plugs takes more than 0.1W.

    20-odd million homes times near 20W is a small power station overnight, completely unnecessarily.

    We are using the LIME plug for this (no longer available, but same idea).

    Well we don't have cable, just freeview but Humax say our box draws less than one watt in overnight standby. 16 W if it's in 'instant-on' mode. But it can't be switched off because then it can't record programmes, which is the whole point of having it!

    The issue with these devices is that they don't seem to be very well made....

    I had two (I think) Belkin 'conserve' run down plugs which both failed. I'd probably have a go at repairing them now but they went in the bin. Had an Ansmann one for the last few years but that seems to have failed.

    The printer runs on an Energenie with a remote switch - the switch isn't great so not sure how long that will last (although if it's actually the switch that fails would be an easy repair)
    https://www.youtube.com/watch?v=9z0mxfpN0ig (notes that these consume nothing when off and about 0.25 watts when on.)

    you can now buy very cheap Wifi plugs - I've got a couple of Sonoff S20's which you can buy for well under £10 which do give the impression of quality well beyond what they cost. https://www.itead.cc/wiki/S20_Smart_Socket claims standby is under 1mW.

    Also have an E-on Powerdown which switches my subwoofer on/off with the amplifier that has quietly done it's thing for over a decade. (When it detects current to one device it switches on power to a second). a search for 'standby saver' brings up loads of product.

    Agreed. I just want something that I can fit and forget, but it seems to be very difficult to find. I have four cheap mechanical timers as backup, but I know they will fail if I use them regularly. I had committed to a policy of buying TimeGuard because they seemed reasonably well designed and made, but one failed a year or so (to be fair it was under warranty and they replaced it, but there was still hassle) and another one's just failed, so I'm changing my policy now. Half the problem with these things is that they sit there quietly doing their job and sometimes it's not immediately obvious when they've stopped working.

    I've got a couple of Teckin plugs but I think they need flashing with some new firmware before I can use them and I haven't done that yet. That's why the HS110 that I can use straight out of the box was attractive and at least I know the brand name. Time will tell!

    With all this poorly made and failing tech, does anyone consider the embodied energy/ emmissions in them going in the bin compared to the savings?

    A few years back, we had a timeswitch on the telly/video and when it failed in under a year I just thought Im binning more resource than Im saving.

    Anyone ever crunched the figures?
