LightwaveRF Energy Monitor

Overview Shipping Returns Support

Need advice? More information?

The LightwaveRF Energy Monitor allows you to monitor your home's energy usage. It is extremely easy to install as the device simply clips onto your mains power supply cable.

The Energy monitor can be used with the LightwaveRF WiFi Link controller to give you a real-time indication of your current energy consumption and cost per minute.

This information can even be sent directly to your Smartphone or PC, allowing you to remotely control appliances, heating and lighting - even if you're away from home.

Energy monitor
Update to link box is required for energy monitor to operate correctly - this was carried out by support very quickly. Only shows current and previous days usage. May be difficult to do but a graph showing a longer period would be useful. One minor thing if device loses power it resets current days usage back to zero. But basically does a good job.

Can I use two of these at the same time to monitor my workshop supply and my house supply?
Guest Visitor 24 Apr 2016
BEST ANSWER: If they are at the same location and connected to the same Lightwaverf LINK unit, then yes. If at 2 different locations, then you will need a Lightwave link connected to wi-fi at both locations, set up 2 different Lightwaverf accounts with 2 different email address's, one set up for home and one set up for workshop, then you will have to keep alternating, logging in and out of the app, to view each separately. it's a real pain, i just use 2 iphones at the moment for home and workshop until they sort out multi location support for the app.
Its pitty that I purchased this as in Europe for example at flat, appartments and homes we have 3 phase electricity and this meter can measure only 1 single Phase. Modul have 3 inputs for clamps but delivered only one. When I contact RF they cant help me where I can purchase only additional 2 clamps. Is so problem to tell me who produce clamps for RF? Or order only clamps. Whats happen if clamp is broken, burned, cable cut ect? Buying a new one? Please help where I can find 2 additional clamps for this module. Thanks. Regards from Slovenia EU where we have 3 Phase electrical connections. On phase for boiler, one for cooking one for heating...

How does this work with a Vera Lite using a RfxTrx device? Or is there a better device to do it with?
Paul W. 4 Oct 2015
BEST ANSWER: The RFX/VERA combination will only support 433MHz LightwaveRF devices (dimmers, relays, sensors etc). The energy monitor, like the LightwaveRF heating products, uses 868MHz and cannot be used with RFXtrx433E.
