Takealot removed it from their site. On Geewiz site it states no longer available. Looking for alternatives now.

Can't see your location on the mobile app. If you're in Pretoria, CQ Electrical sell the Radiant power meter for about R210

In Boksburg though... But thanks... think I remember Discount Electrical also do the Radiant one. Just couldn't remember which brand they had. Will check them out.

Keep in mind actually measuring AC power consumption is not completely trivial.

It is the reason the Kill-A-Watt is so popular in the US, it is super accurate.

They use what is called a true RMS meter. Low quality meters (which isn't determined by price), basically use a very simple average voltage measurement and multiple the amps to give you the amount of power used.

The Kill-A-Watt samples the incoming power a bunch of times for every cycle. Every time it samples it measures the current also. The difference in accuracy can be quite large.
