    The missus is suitably clued up on the usage scenario and is keen to use everything in the day. She has taken to watching the meter quite well and seems to be keener than me to use our lecy! Hope she keeps it up.
    When she switches something on she runs outside to the lecy cabinet to see if the LED is on or off. If on, she is happy (exporting), if its off, she waits for a burst of sunlight. (Is this excessive behaviour?). Martin

    Absolutely not. We do it all the time!!!!
    We have been known to turn our washing machine off more than once (7 times once) during a wash cycle because a cloud or two has appeared. We even wait to put our travel kettle on before having a cuppa. It can be nightmare if we are up the garden working on the veg beds cos we do not allow ourselves a tea break until the sun comes out. Seriously!!:D

    How else would we only use 1 to 2 kWh per day during the summer.

    Our madness does pay for itself, honest!! Leccy DD of £19 per month and no gas!! :)

    I have seen a few DIY and commercial units which monitor the import meter LED, but as I just want to know if the LED is on or not, I will have a go at a DIY sensor that will just basically (wireless'ly) relay the state of the LED so I can put it in the kitchen. Maybe something very cheap and simple!
    I don't really need to see how much I am importing, just the fact that I am importing!

    (Our lecy meter is outside so not so convenient).

    Take a look on ebay at the EON energy monitors, they are current cost meters in disguise. I bought one for £15 on the advice of Martyn, it fits over the LED flasher on your import meter, then when you're exporting it shows as zero(time to turn something on as my wife says), works perfect for me.
    You can add extra sensors too to your generation meter LED which you can tune to another channel to show what you're generating. All done wirelessly.
    I have both, but in all honesty it stays on the import and I'm happiest on zero.


    Just make sure if you get one its the EnviR model, you will have to buy an optismart add on for the LED, sorry...forgot that bit, it's been a while. You can just use the clips instead(should actually be more accurate)
    Here's one http://www.ebay.co.uk/itm/EON-Energy-Saving-Monitor-Meter-Electricity-Monitor-/271924939519?pt=LH_DefaultDomain_3&hash=item3f4ffd4aff

    EON energy monitors

    I already have the British Gas one, I had it clamped on for a while but it is so inaccurate I removed it. Of course it doesn't differentiate between import and export, so not really much use.
    I packed it away.
    I will have a look around, you have pointed me in the right direction.
    Thanks

    In that case ...... have a look at the BG monitor, see what it says on the back. I was given a SWALEC one by a friend and that too is a Current Cost model. It's an ENVi so not as good as the ENViR's Eon gave away, but still works piggy backing off the Optismart LED readers that my two ENViR's display. The main difference is that the ENViR's will display on their main screen, and do extra calcs, whereas the ENVi displays on one of the 9 device screens.

    All three monitors came with cable clamps and data senders, I just put those away, and used the Optismarts instead to send info.

    Edit: Once you get down to about 1A or less (230W or so) the clamps start to get iffy.
