This device would be interfacing to the CS via the serial interface.

Single-Phase, Bi-Directional Power/Energy IC

Reviewing the datasheetthe device is a dedicated chip for performing voltage, current and energy consumption calculations. Immediately, a resistive shunt used to measure current can be seen on the bottom right of the green PCB. Learn how your comment data is processed.

I found it easier to prise the unit apart from the bottom. Fill in your details below or click an icon to log in: Post was not sent – check your email addresses! Also, is there any scope to hack the device, similar to the Tweet-a-Watt? Share your thoughts Cancel reply Enter your comment here Current measurement is performed using a resistive shunt.

This would be used for the auto-boot function described in the CS datasheet and it would contain calibration and configuration settings. Once the case datashert apart, the internals are quite compact. Does the device use a current transformer CT? A flat blade screwdriver is useful for prising the case apart. Or a resistive shunt which would be much cheaper?

There is some scope for customisation here. Email required Address never made public. The two heavy gauge wires are the active connection.

Is there some sort of custom IC performing the energy measurement? A bonus is that the serial interface pins are clearly labelled on the PCB adjacent to the ribbon cable on the top right.

At that price, I was curious, how does someone manufacture and sell for some sort of profit a device that can measure up to W of power. This site uses Akismet to reduce spam.


But, I am aware there are some requirements relating to the types of capacitors that are used. Sorry, your blog cannot share posts by email.

Anyway, a resistive shunt is used for the low cost current measurement and a custom IC handles datashset the power measurement calculations.

When in service, current from the rear male prong connects to the obscured red wire, passes through the resistive shunt and then through the other red wire to the front female contacts.
