What else do you have hooked into it? Is it just that module? I want to set up electricity monitoring in a number of places but I don't have any other home automation gear setup - what do I need in that case? </pestering questions>
It's literally just this unit fitted inline

It measures the consumption travelling through it and I connected one to a multiplug which I can move around. Your phone connects to it and that's it - you see whatever is flowing through it! In addition, you can switch it on/off remotely, schedule etc - but I'm just the energy meter

Anyone else know what the rates are for the electricity they buy. Just saw this on ABSA when I bought some.

85.4 KWh @ 133.88 c/KWh
300.0 KWh @ 163.16 c/KWh
8.9 KWh @ 182.74 c/KWh
Total 394.30 kWh

Electricity R620.02
VAT R86.78
Total R706.80

That's BS pricing :mad:

Roux, I currently buy 596.50 kWh a month.
All in for R1150

Thus all inclusive R1.9279 per kWh.

Not in Stellenbosch anymore, moved to Somerset West a year ago so we fall under CoCT.

Do you have a monitor similar to an extension cord? One end would be plugged into a wall socket and the other end would take a multiplug extension cable with TV, decoder, amp, android box etc.

It would measures usage of that group of devices. Easy to unplug and move from room to room.

You can make your own.
You'll need 1 extension cord, 1 Sonoff Pow and some time.

Using this to measure my lounge power.

Tks that's perfect.

Where do you see the usage? Can't see on their pics. Do you take a reading and then check 48 hours later? Actually I've been looking for an excuse to use sonoff AND it's on sale. Bonus :)



Yes, that would work, can just plug the extension cord in. Will check it out tks.

You have an app on your phone that shows you the current usage.

Excuse the iPhone resolution. App isn’t 100% for iOS.

Will contact them tomorrow, that's pretty useful and like I said I'm looking for an excuse to start a sonoff setup. I've been following the threads for a while.

Appreciate the help.

That's even better.

Five people in the house and usage goes from 35 to 45 per day. There must be somewhere we can cut down.

Hi,

Yea I've done exactly what was said said above : I took a multiplug and added a Sonoff POW (or R2) to check my use.

45 units a day? Even with 5 people in the house, are you constantly running baths? Is your pool pump going all the time? Is the fridge door being opened and closed all the time? I don't see how people could each use almost 10 units themselves a day.

It seems impossible yet the electrician told us that's normal for a house with 2 geysers :wtf:

Pool 6 hrs p.d
2 x PCs 24 hrs p.d
1 x Mac 24 hrs p.d
5 x TVs 24 hrs p.d.
2 x 150l geysers (4 x cleanliness maniacs who shower at least once a day)
2 x loads washing per day (same cleanliness maniacs wear a thick hoodie once then wash it). A+ rated Miele washing machine.
1 x dishwasher every 2 days.
10 x day/night garden lights

Fridge gets opened quite often - normal use

Please can somebody work out for me what 10 x 14w garden lights cost per day if they're on for 10 hours at R1.32 kWh. I've confused myself with all the zeroes :)

P.S. ordered one of those sonoff plugs from geewiz so we should get an idea soon of where the power's going.

140W over 10 hours is about 1.4KWH a day so about R1.90 a day more or less

Computers could be using a fair chunk of that. Maybe turn those off?
