efergye2 Classic 3.0 Wireless Energy Monitor (Latest Version) with elink Energy Management Software (Windows and Mac Compatible)

I found this monitor very easy to set up and configure. I have economy 7 but I only needed the single sensor as supplied. However, the software on the disc did not work (Windows 7). Go to the efergy website and download the latest software then there is no problem. But do make sure the date is correct on the monitor. This gives a good record of my usage over several time periods. After watching the real time energy consumption on the monitor, I think this will pay for itself very quickly in savings.

Disturbed by ever rising energy prices, I decided to have a closer look at the electricity usage monitors available on the retail market - from which there are many to choose! The efergy E2 and the OWL wireless monitors , the type that sample total electricity outputting from the house electric meter, were picked to evaluate as both appeared to be claiming market leadership and both had similar favourable reviews. The display monitors of each are incidentally, remarkably similar in appearance The price for both was also similar, and for no particular reason I ordered the E2. This model is capable of downloading usage information to a computer software programme. The goods swiftly arrived from an Amazon supplier and the, plainly, good quality items were inspected and, using the set-up manual, quickly installed. This is a very simple procedure that takes barely a minute or so, after a manual pre-read through. The sensor is clipped around the identified cable exiting the electric meter and plugged into the small, eggcup sized transmitter. That's that and the duo can be left together by the side of the meter and within the meter box - if you have one. The transmitter will have been previously fitted with the appropriate AA batteries. With the display monitor to hand - also now fitted with AAA batteries - a small button on the back and a button on the transmitter are pressed - the manual instruction is quite clear on this. It is a rapid and simple procedure. The monitor should now show a steady `wireless' emblem and a small LED indicator should flash on the monitor and the transmitter at about six second intervals. That's it! Job done! The monitor can now be placed anywhere within range of the transmitter (about 40m) in the building, and will display data as wished. The manual is again clear on the various preferences one might wish to display.Does it work? Well, initially mind did then didn't! My house is a modern semi with the meter box on an outside wall. I was not over confident that a flawless initiation would be achieved and I was right! Within a short time the `wireless' emblem was flashing and a line of dashes had appeared where there should be figures. The manual says this situation indicates a loss of contact between the transmitter and the monitor.A further emblem was also flashing. It looked like a battery symbol. No mention in the manual of this - or indeed any other symbols, currently unknown that may at some time appear. However I rechecked the batteries and one in the transmitter had slipped from a tight fit in its slot. On correcting this all became well. The set-up is now working perfectly and by experiment have placed the monitor throughout the extremes of my house without loss of data. It is quite clear from observation that when, for example, an electric kettle is switched on, a 2kw increase in the displayed data is shown. Similar changes can be seen when switching on or off other appliances and lighting.This is a very intuitive piece of electronics and I hope when this `honeymoon' period is over I will not have become obsessed with forever closing down the house electric's system and living a life in semi darkness! The accuracy of the read-out data will not be of the quality of the official house electric meter but is still given as greater than ninety percent. At this level it will allow a reasonable check and comparison of usage against an electricity bill detail. It will activate a new energy awareness discipline I am sure and that is my prime aim.I haven't got round to using the software facility as yet - these are early days - but this promises to be interesting, when the historical data gathered by the monitor can be downloaded and displayed in various graphic forms. To conclude, this equipment will surely provide, for anyone, a more disciplined approach to energy use and will certainly appeal to gadget lovers or those who just love an analytical challenge!Pros: The components in the box appear well made and of good quality. Supplying Company has good reputation and a UK phone number! Reasonable cost. Simple to set up.Cons: No batteries supplied as standard. Instruction manuals okay but contain a few minor (non technical)errors and could be more comprehensive.

Hardware InstallationThe monitor and sensor were setup with ease following easy instructions. Had the monitor working very quickly indeed.Software installFor a Mac it was pretty grim. Efergy have not registered the application with Apple so straight away users are faced with a warning that that this software maybe dangerous and requires an administrator security override in settings. Next it spawns multiple other application/ driver setups. Most Mac users have never had to install a driver do this is very odd indeed. Two driver installs and an install of Adobe Air you are required to reboot the computer. Most Mac users go months without rebooting, so this is odd too. Overall a great sense of unease is instilled by the Efergy eLink install.Monitor usageIt worked well reporting realtime costs, energy usage and CO2 consumption. Additionally provided average usage for day week month. As a coffee table electricity monitor it does an adequate job.eLink SoftwareThe initial concerns were bourne out by the usage. It is an un Mac like app, it appears that the authors of this software have never seen a Mac OS X application. The design is confusing. On a Mac the magnifying symbol is used to indicate Search, but on this app it is resize the application. The usual three traffic lights in the top left of EVERY Mac app are absent here. So instead of pressing the Red traffic light to close the app as used in Every Mac app this instead requires rummaging around the application to find a button hidden away on one of the screens.Transferring data from the monitor to the Mac over the supplied USB cable was incredibly slow, took several minutes to collect a couple of hours of data. I dread to think how long it would take to download a few weeks worth of data, hours by the rate demonstrated.Overall the application is very pretty but largely alien yo any Mac user, navigating around using the unique design style employed requires significant effort and concentration. A great pity they did not follow all the standard Mac design rules and made it much much easier to use.OverallAs a coffee electricity monitor, it is solid, competent device.But trying to do anything else using the Mac eLink software is very disappointing and with, more competent products available not worth it, so I have returned mine and purchased a competors.A great pity.

This truly was "plug and play" on my mac. Downloaded the software, installed the USB drivers, added 3 x AAA & 3 x AA batteries, connected the sensor to my "mains In" in the garage, pressed the "Link" button and everything was up and running in under 15 mins. The sensor and receiver work through a thick structural wall between the garage and the house no problem at all.

If you already have 90% led bulbs/low energy appliances its a waste of time, it only confirms your not using much energy.Its pointless/doesn't work well for anyone on a dual tariff/so doesn't display the summary accurately. I think the old spreadsheet way was actually a lot easier.The alarm is similarly pointless, its not exactly very bright, load or act in a way that would make you go over and look at it.I found setting the thing up in the first place difficult, again, doesn't help its not designed for dual tariffs that alter after a certain amount of kw's used.If I had the chance I would have returned it.

Super Teil , ich habe es angeschafft weil ich ein extreme hoch Stromrechnung bekomme und konnte nicht glauben das ich 800 Euros nachzahlen müsste.Am Ende hat sich herausgestellt das ein Kabel der von mein Sicherungskasten kam , direkt in der Garage von Nachbar landete . Er selber wusste es nicht aber dank des Gerät könnte ich es klar nachvollziehen.Das Teil ist super da man nicht direkt Strom Kabel klemmen muss, die Magnetfeld Sensor arbeiten super und sehr präzise.Das einzige was man beachten muss ist das die nur den Strom messen und nicht die Spannung, da aber die Leistung aus Strom und Spannung gerechnet wird geht das Gerät davon aus das die Spannung immer gleich ist , die kann man aber einstellen, zb 220v .Ich habe jetzt mehr als 6 Monaten in Einsatz und es gibt kein Abweichung zum normal StromzählerWas ich toll daran finde ist das man lernt viel dazu, was alle unsere gerät verbrauchen , Kühlschrank, Back Ofen, Wasserkocher, Mikrowelle, Trockner, Spülmaschine, Lampen, ....Allein dadurch entwicklen man ein gutes Gefühl und kann etwas Stromkosten sparen.Die Batterie halten lange und die Reichweite von Sender ist sehr gut , bei mir von Sicherung Kasten , durch 2 Wände , überhaupt kein Problem ...Einzige minus , das auswerten der Daten am PC durch USB Kabel an eine MacBook ( also nicht Windows ) ist sehr mühsam , aber richtig übel .Achtung , Arbeit an Strom Leitungen ist gefährlich. Liebe ein Elektriker machen lassenUnd die Klemme funktioniert nur über ein Phase, es geht nicht wenn es über ein ganze Kabel samt Phase neutral und Erde gezogen wird

Génial franchement pour le prix, permet de suivre sa consommation en temps réel et ensuite avec le logiciel PC, parfait montage rapide et tout fonctionne. Si vous voullez savoir ce qui consomme et se met en route quand il ne faut pas. A acheter les yeux fermés

És un aparell electrònic domèstic, NO PROFESSIONAL, que serveix per mesurar el consum elèctric d'una casa.En el meu cas el vaig comprar per saber quin és el consum real del meu domicili, i sobretot per conèixer quines son les Puntes de Potència, és a dir, quina és la potència màxima que consumeixo en un moment donat.Ja sabeu que les factures d'electricitat tenen 2 parts diferents: una part fixa, que depèn de la potència contractada, i una part variable, que depèn del consum. L'estratègia de les companyies elèctriques consisteix en anar pujant brutalment la part fixa, la que depèn de la potència contractada; i a més, la part variable de la factura, la que depèn majoritàriament del consum, també depèn indirectament de quina sigui la potència contractada.La finalitat de la compra és saber, amb xifres a la mà, si el terme de potència que tinc contractada amb ENDESA és la correcta, o bé si puc baixar-la, amb la conseqüent reducció de la factura elèctrica.L'aparell és molt fàcil d'instal·lar, i de fet hi ha vídeos explicatius a la pàgina del fabricant. No s'ha de desmuntar res, tan sols s'ha de posar una pinça envoltant el cable d'entrada d'electricitat del quadre elèctric del teu domicili, i connectar-ho a un emissor inalàmbric. L'emissor inalàmbric es connecta fàcilment amb l'aparell principal, que consta d'una pantalla digital on van apareixent les lectures a temps real.Es pot configurar el lector perquè faci lectures cada 10, 15 o 20 segons, que queden emmagatzemades a l'aparell principal. Es poden baixar les dades a l'ordinador mitjançant un cable USB que ve inclós al pack, i a la pàgina web del fabricant et pots baixar el software corresponent per gestionar les dades. El programa és senzillíssim d'instal·lar i de fer funcionar. Fa resums diaris, setmanals, mensuals... etc, amb tota mena de dades, gràfiques... molta informació i fàcil d'entendre per als que no som lampistes ni tenim gaires coneixements d'electricitat.Tot i que no és un aparell per a professionals, les lectures són força ajustades al consum real. El lector capta fins i tot l'engegada/apagada d'un sol aparell, com extractor de fums, una làmpara, un aparell de TV, una ràdio... és molt sensible.En el meu cas porto menys d'un mes amb aquest medidor, i falta realitzar medicions de consum a l'estiu, amb els aires acondicionats en marxa, però el pic màxim de potència registrat fins ara és de 3,78KW. Si tenim en compte que tinc contractats 9KW, crec que tinc molt de marge per baixar la potència i estalviar en la factura d'electrictat. I de passada, ajudar a fer un planeta més sostenible.Ampliació 15/01/2018: Ja porto més d'un any amb l'aparell instal.lat i monitoritzant el consum i els pics de potència. Això m'ha servit per pendre la decisió de baixar la potència contractada amb la companyia elèctrica de 9,2KW a 6,9KW, amb la conseqüent reducció de la tarifa elèctrica de la part fixa de la factura.A més, he canviat de companyia i m'he passat a SOM ENERGIA (@SomEnergia), una cooperativa sostenible i amb energia verda. HO RECOMANO A TOTHOM! Paguem menys de la factura elèctrica, consumim energia neta, i a més fugim de l'Oligopoli energètic!!!

Il prodotto è arrivato prima del previsto, di semplice installazione seguendo il mini manuale in inglese (in italiano lo trovate su internet) oppure guardando il video dell'installazione su you tube. L'ho comprato per monitorare l'impianto fotovoltaico SolarME ( [...] )e quindi avere sotto controllo la produzione del'impianto per avviare i consumi in casa. Comodo la possibilità di scaricare i dati su PC con cui poter effettuare diverse valutazioni (punto di picco impianto, produzione a tariffe diverse, inseguimento dell'obbiettivo di produzione mensile, report della produzione da salvare anche in excel per usare i dati a piacimento). grande display, possibile vedere la produzione dei giorni precedenti come delle settimane e dei mesi anche sul piccolo display...L'unico neo è sicuramente la precisione non perfetta 95% circa (essendo una pinza amperometrica si deve impostare il voltaggio che generalmente è sui 235-240 per avere una misura del kw esatto), inoltre il software versione 2.3 creava problemi in lettura dei dati quindi passato alla versione 2.2 che fà il suo lavoro in modo egregio, si aggiunge la non possibilità di poter monitorare i consumi (dell'enel) per case che hanno un'impianto fotovoltaico in quanto la pinza amperometrica non fà differenza tra energia immessa o assorbita quindi o ci si accontenta del consumo in casa e non del prelievo dell'enel oppure si deve abbinare la "pinza" ottica da comprare a parte. P.S. nella confezione non esce il trasformatore per l'alimentazione del display ma è anche vero che con le batterie funziona ed è più facilmente trasportabile

La instalación muy sencilla, la pinza amperimétrica es pequeña y entró perfectamente en el cuadro eléctrico; la configuración del aparato muy simple y rápida. De momento, me ha servido para detectar que un microondas en reposo gastaba 50w, también que no debo bajar la potencia contratada y con la alarma nos avisa de consumo excesivo con lo cual va a mejorar el consumo energético. La precisión de estos aparatos debe ser bastante aproximada, pues nos está midiendo la potencia aparente y no nos mide la potencia reactiva con lo cual, nos dará un pequeño error. Para mi lo más útil es que nos avisa cuando hay picos de consumo que excede de lo que he marcado como límite, de esta forma también nos ahorramos un disparo del ICP con el consiguiente estropicio en caso de tener un aparato conectado (un ordenador)Muy recomendable.
