## Questions & Answers

**Q: What exactly does this thing do and how does it do it??? Just really confused. Thanks!!**
A: What does it do: Measure the KW/h that your house is using on realtime, by day (and average), by week (and average) and by month (and average).How does it do it: You clamp sensors on the cables that enter your breaker box, and the sensor transmit this information to the device. They have a very good range of action

**Q: Can I use this to keep track of the electricity used on a monthly basis by a tenant in a back cottage? The cottage has its own subpanel.**
A: YES you can . I would recommend the Efergy Elite True Power which is hard wired in. Use the engage hub to monitor on-line and let you tenant view their usage too.

**Q: Do you have a 220v version as I dont live in the usa?**
A: There is a 3 phase version also available on Amazon . This model can be switched between 110v & 220v single phase.

**Q: can the energy elite be used to figure out how much to charge a tenant living in my guest house we have one meter on property ,is so how does that wo**
A: No. The Elite will not be able to differentiate usage on the one meter.

J'ai deux appareils l'un contrôle la pompe a chaleur l'autre les plaques a induction. Le fait d'être directement dans la cuisine permet de ne pas disjoncter par grand froid.
