Review: efenery additional monitoring - all i needed to monitor additional sections in my house. i have 3 of these and now i can see where my energy is going. the efenergy sit is also nice. their graphs are abit limited but you can pull a report and extract that into excel.
Review: Inaccurate Readings and not directional measurement - I purchased the Engage Hub and three CT Transmitters + CT Clamps over the last 5-6 months which are now sitting in a draw whilst I try to get a refund. As others have said, their Customer Support don't reply to my emails, and as I refuse to sell on a faulty product, I have wasted over £200. My problems are broken down into two main issues: 1/ The accuracy of the kW usage recording is very inaccurate, my electrician estimates up to 30-40% over reading; 2/ The clamps are not directional, which makes installation easier but the CT clamp doesn't know if the flow is from the grid to my house or from my solar to the grid! Both are recorded as usage in the App! I have asked for a full refund but still have not received any reply. If you want a display of meanless figures, that bear no relation to your electricity usage, then this is the product for you! Otherwise, steer well clear.

## Questions & Answers

**Q: Is this the Engage sub monitor kit that is needed for tracking my solar panel generation?**
A: Yes. In theory. It should clip on to the cable at the solar generation meter.
I have set mine up and can see it on the screen but it gives me a zero reading as I have a ground mounted solar system in the garden so the wireless signal is too far away.
If your solar meter is in house near you consumer meter then it should be fine.

**Q: What RF frequency is used by the transmitter?**
A: 433Mhz i think.

**Q: Does it go around the live or the bundle of live/neutral/earth? Can the information from multiple sensors be shown on one website?**
A: Like the standard energy monitors, this is for "whole house" monitoring and must be clipped around the live (positive) cable only. Please note this is not a complete energy monitor, it is an additional transmitter and sensor for use with the Efergy Engage hub.If used with an Engage Hub, you can see each phase.Hope that helps

### ⭐⭐⭐⭐⭐ efenery additional monitoring

all i needed to monitor additional sections in my house. i have 3 of these and now i can see where my energy is going. the efenergy sit is also nice. their graphs are abit limited but you can pull a report and extract that into excel.

### ⭐ Inaccurate Readings and not directional measurement

### ⭐⭐⭐⭐ They work as expected but accuracy and especially linearity is quite poor due to manual voltage adjustment
*by R***. on 13 September 2015*

I added two of these kits to an existing Efergy engage to measure two of my HVAC's. They work as expected but accuracy and especially linearity is quite poor due to manual voltage adjustment. This method of measuring energy has its limitations but a gives good picture of trends and times of fluctuating energy consumption. The ability to have five different measuring channels on same dashboard is a great plus. In general I am quite satisfied with my purchase and the ability to monitor my house and HVAC energy consumption also remotely from an internet cloud.
