What else can this energy monitor do?
This smart meter is also capable of turning off your devices from wherever you are, with an internet connection, and you can even see the difference in energy usage. This can show just how much energy you can save by turning certain appliances off.

Please note: You will require the optional LightwaveRF Wi-Fi Link A23RX.

Rated 5 out of 5 by from I purchased this last week to go with my ever expanding collection of LightwaveRF products. So simple to set up with the WiFi link controller for the iPhone. I can now manage my electricity consumption easily, and I'm confident That it will quickly pay for itself. I can monitor my electricity consumption from anywhere in the world I really can't recommend LightwaveRF products enough, they just work. It's even easier now the new new app is available I'm not a LightwaveRF or Maplin employee, and rarely write reviews; but credit where it's due.

Rated 5 out of 5 by from I bought one of these along with a "Wifi Link" and a 13A socket on Friday night and much to my surprise had it all installed and working in 30 minutes. I've been playing with it all weekend and it seems to work perfectly :-). I had been meaning to try out home automation as I'm away from home a lot and this seems to fit the bill perfectly and is reasonably priced. The hardware is of very good quality but the software is rather amateurish - I hope this will be fixed as it lets the product down. The software works but is rather clunky. The instructions are not in Chinglish but proper English and once you get the hang of how it all works its easy. There are some good You Tube videos which makes operation clearer. The controller box & system is not really Wifi in that it operates at about 400kHz but the principle is the same and it works much better - through very thick granite walls in my case. The Energy Monitor works well and now I can turn lights on & off, check my power consumption all via the internet. I'm just about to use the relay LightwaveRF sell to turn my oil CH boiler on and off until their heating controller is launched. If you are toying with the idea of trying Home Automation why not give this a try. For Ј100 you can't really go wrong for a basic setup. Well done Maplin & LIghtwave RF! I have absolutely no connection with either company but am an inveterate gadgeteer.

Rated 3 out of 5 by from Doesn't support dual tariff (Economy 7) Disappointed that the LightwaveRF smartphone app and Web app only work with one electricity tariff. The LW600 Energy Monitor will happily transmit how many watts you're using every 15-30 seconds, but if you have Economy 7, the app currently can't take into account the fact that it's at a cheaper rate for approx. 7 hours during every 24 hour period. This means that the app's calculated cost of electricity used is always going to be wrong. Also, at the time of writing, the Maplin Product Details Overview states: "This smart meter is also capable of turning off your devices from wherever you are . . ." I have seen no evidence of this in the LightwaveRF documentation. The app in conjunction with the WiFi Link can turn devices on/off, but I don't think the Energy Monitor can. Because of the Economy 7 issue, I returned my Energy Monitor to a store under the Maplin 30-day money-back policy and exchanged it for a light switch from the LightwaveRF range.

Rated 4 out of 5 by from Works OK but range less than 30m claimed It works OK but I've had to move my wifI link to get it within range which is <20m. Still misses some readings. However, useful bit of kit for the price.
