Cheap Onzo Energy meter - £8

[HTTPies]

Chaps, does anyone want one of these in green? I ordered 2 and don’t like the green so am keeping the orange one.
If it doesn’t work just bin it. If it does can you pass it on and buy a homeless person a coffee & a burger when you next see one.
First to pm me can have it & will post first thing tomorrow.

As mine appears to have died can I bagsy this one?

Even with spare batteries mine is now reading 1600w even when nowhere near anything Think the clamp unit is throwing a wobbly

Sorry I got there first. Many thanks as well received. Not had time to test it yet. Beer vouchures deposited in BHF bin last week.

No worries

Mine is definitely throwing a wobbly, its not the batteries but the clamp meter is giving spurious high readings even while not connected to anything!

I'm wondering about mine now. Readings daily are far higher than our average electricity use last year.

And we still haven't put the heating on yet. Plus I'm going to have a stroke with the amount of times I have chased the kids whenever I see the meter spike.

Pretty sure my second one is ok
It was the kettle test that showed the first on is in error followed by the leccy fire test.

However having gotten over the entertainment value, it's not really changed actual usage

Another one her which seems to have died. Couldn't get it to work for more then a day or two before it would loose signal.

Pairing it then became totally hit or miss!

Hmm....

Mine has been ok since I fitted it, still on the first set of sensor batts, second set in the display. Also got the monthly bill from Octopus which agrees with the gOnzo.

Given I'm fresh out of things to turn off, it's now mostly a paperweight.

[TurboRob]

Bought one of the £6.39 ones, installed this morning and working a treat!

Cheers to the OP and others for posting about this.

I finally got around to fitting mine today - working well so far (I think!) but having looked at the manual, I realised it could download data to some SSE web/app/location - as I'm not with SSE, so it's not going to work for me, so I thought I'd see if anyone's managed to 'hack it' to get at the data. It seems they have! Found on the Navitron website (which I've browsed before) and whilst I've downloaded and run the software, I don't think my Onzo has been on long enough to generate any data yet.

Just an update on battery usage. My base station batteries have finally died, fitted 3 x Duracell AA on 2nd Nov, so they have lasted nearly two months.

Need to sort out a USB option, although my leave it off for now as the device has given me the info I needed on my 'standby' power consumption.

You all had me interested, but then I remembered my own setup.



I suppose I could run the CTs over the single phase side of things.

My screen went this weekend too, so the batteries on mine that were in the screen when I had it lasted about 6 weeks.

Mine has started doing weird things after Xmas. Display flashing, goes to zero then displays power then goes to zero, then displays dashes. I suspect that the meter end batteries have died or its stopped transmitting.

Hi there
I've just gone and bought one of these meters from eBay but there were no instructions in the box aghhh!
Are there any on line anywhere as I can't find them anywhere?
Or can anyone give me a quick summary please as it can't be that hard? I assume I don't need an electrician??
Thanks
Melinda

Here you go:

To be honest it's a bit flakey but can be a guide to what you are using. I found the distance between the sender & receiver to be a bit limited. Read the rest of the tread about the leaky batteries in the sender.

en4rab's post on page 8, though his website/hosting seems to be down at the moment. It was working on the 1st Jan 2019 though!

you can get the patched onzo downloader here:
https://www.en4rab.co.uk/onzo/

Its been ages since i messed with it, from memory the only difference between iplan_dumper.zip and onzo_dumper_date.zip is the format of the date in the csv file it generates.
I think one is in unix time and the other in date and time.
The source zip is the patched uncompyled app if you want to make your own changes, you can turn it back into an exe using py2exe.

[Oakey]

Do these still let you upload the data or has that been binned off? I'm trying to find an energy meter to replace my Geo Minim that has data logging with apps or browser and the only options seem to be Loop or Owl.

For £6.50 they're really good. Mine came without batteries, but seems happy on Alkalines.

I've got a small 600w solar system, and these meters seem cleaver enough to measure current flow direction such that it reads zero when I'm exporting back to the grid...which is nice. My other meter just got all confused.
