    Just wondering what the mains sockets and light switches do after a power outage. Do they have flash memory so they can return to their previous (on/off/dimmed) state after a power cut, or do they come back to a factory setting?

    Actually, just as an aside to that, does the Wi-Fi Link have the ability to run a user-defined power-up activity? Would be nice if it could be set to do something specific when it reboots after a power outage (not sure what, but I’m sure there could be uses, LOL)

    the sockets and dimmers should retain their memory even after a power cut. The only exception is the lock status which should revert to ‘unlocked’. This is built in as a way to reset the unit incase the lock control is misplaced.

    I dont think the wifi-link does have a user configurable setting on power up – we tried to make it as simple as possible so as not to confuse the average user. Could possibly create one but i dont think wed put it on the retail products.

    I’ve plugged my WiFi unit into a UPS (along with routers, NAS, etc) to avoid reboots asn I seem to have problems with Time Not Set on re-boots as the WiFi unit comes up before the Router on Power On situations.

    2 WiFi, 2 sockets, 11 light switches (7 single, 4 double), 2 mood controllers, 1 double wire free switch, 6 plug in on/off, 3 plug in dimmer, 2 PIR, 2 LED, 1 300W Inline relay, 2 signal booster, 1 Energy Monitor and 1 very patient wife. Also Heatmiser's Neo, Ring Bell, Ring Camera, Nest Protect, Canary...

    Hmm, not sure if my sockets are faulty then, because all four returned to the "off" state, rather than their previous state, when I recently had to turn the ring main off to install a new socket.

    Obviously that behaviour is not good at all. Even a brief power outage would cause every socket to turn off and STAY off after the power is restored, which is not what a normal (manual) socket would do. This could cause major problems – fridge/freezer, security/safety lights, cable box (which needs to stay permanently on for timer recordings), etc.

    Just hoping there isn’t a power cut while we are away on our holidays later this year if this isn’t a simple fix!

    sockets default to off when the power comes on as a deliberate safety feature – they do have memory so could revert to previous state but do not for safety.

    Oh dear, that’s not what you said before when I asked (see above) and I fear it makes them virtually useless for many uses (e.g. for powering phone base units, video equipment such as VCRs, cable or Sky boxes, modems/wi-fi routers, fridges, freezers, household lights, clocks, security systrems, … erm, in fact most things really).

    If a switch is turned on, it should still be on after a power outage, not leave the whole house turned off! If it was off, it should also return as ‘off’ when the power comes back.

    If if was a safety issue, manual switches (and even circuit breakers) would always turn off after a power cut, and they most certainly don’t.

    Please can this be resolved, as I’ll certainly need to remove at least one of mine now (the one powering the answerphone and Virgin TiVo box) before we go on holiday.

    Though I haven’t installed the sockets yet, I have to agree with Andre. I think the sockets should return to the state they were in just before the power cut. Though I don’t see why you would use a LightwaveRF socket on a fridge or freezer, It’s definitely a problem with VCR’s, TV receivers and in particular, modems/routers.

    Yes, I’m very disappointed by this news, which is not what I expected from these otherwise brilliantly thought-out products (and from the advice given above, before I purchased).

    It makes the wall sockets next to useless for me, as we seem to get maybe 4 or 5 brown-outs a year, but normally everything just comes back on as usual afterwards and all we need to do is reset the odd digital clock, which is absolutely what you would expect to happen of course.

    Please can this be looked into again, and a solution proposed? Thanks.

    Firstly, I appologise for ‘misleading’ you – this is never my intention. I originally stated that the sockets retain their memory after a power cut – this is correct. I initially missed the point that you referred to subsequently where you want the products to return to their ‘on’ or ‘off’ status – apologies for misunderstanding.

    I must reiterate that this is not an oversight or design flaw, however, and is something carefully considered. This was a design feature specifically requested by Siemens our main customer for safety. This is regulation, because, when electronic sockets have no power you cannot tell whether it is switched on or off. On a mechanical socket you can still check the status because of the mechanical switch with the red color towards the top. You can therefore make sure all the sockets are off when the power comes back on – this can be important for some devices and (rightly or wrongly) specified as basic safety. Because you cannot tell on our sockets we are obliged to default them to off, even though we could get them to remember their status.

    I have organised a solution however. The next software revision on the wifi-link will contain a startup default sequence when you can set any essential socket to the automatically come back on when the power cut ends. The next revision is due in a few weeks time and can be done over the air so this will provide you with a solution soon. I will just need the mac codes for your wifi links nearer the time to check i have updated the correct devices. Obviously all future links will have this inbuilt.

    Alex.

    Weve now completed changes to the wifi link to solve concerns regarding power failures.

    On startup the wifilink now emits a radio pulse which will turn on selected devices on power restore. To select these devices when setting this feature up you just need to put them in pairing mode and turn the wifi link on and off again to link them.

    Ill let you know when we will be releasing the software update – it should be over the air and automatic but i may need mac codes of some earier model links so will keep you posted.

    Sounds good, I need to get me a Wi-Fi Link then. :) if” alt=”:)” title=”Smile” />

    Just got back from holiday, I used the low-tech solution of running an extension cable from the kitchen in order to power the cable box and answerphone while we were away (instead of their usual ConnectRF socket).

    Perhaps look at developing a box that can do the above? Although I agree, to an average user keep it simple, but for someone who isn’t average would more than likely help develop the product further for your selves?

    Any news on the API?

    Also, noticed the sockets don’t keep there locked status after a power cut, this is a feature I would prefer that the lock stays on? Example of this would be to lock a socket to off, thus reducing the need for the baby safety plugs? However if they unlock after a power cut, makes this a safety issue <img src=” title=”Sad” />

    I see your point, however you need to be able to unlock them this way as a safeguard in case you lose your locking remote and need to reset them – that was how they were designed.

    Cheers. I’m going to give this a try over the next few days (now I’ve finally got a "B&Q special" Wi-Fi Link :)
