I had a booking for my smart meter yesterday but i was told no useful information could be gathered from the SMET1 and i needed SMET2 is this correct ?

Please can i be advised and if possible to pull statistics from SMET 1 and what type of information can be gathered from the API. I plan on writing a .py module that can be used within my home automation hub "homeassistant" this is the missing component of my home monitoring for me

hi, Guys,

May I request access. Part of the reason I joined OVO was this very forum article. Whilst I am not on-board yet, on Oct 5 I switch and Oct 20th is my smart meter installation, I am keen to get access to this data as I am looking to create multiple apps that I can query with Alexa, integrate with home-assistant etc. I am keen to try and pre-empt energy usage based on weather, historical heating settings from the thermostat etc. and Shift hours. And finally, break down energy usage by correlating the information from my smart plugs.

There are probably loads of ideas out there for this type of data and it is great to see OVO embracing this way of working. As more third-party products come out with their own exposure, OVO will be seen as a leader and will hopefully bring more customers to you as a side benefit.

Can't wait to see what comes of this.

There are some of us that have been on the list for quite a while and there has been no further news on access, so dont hold your breath... There are other small startup providers that are really embracing making all this 'open' to those who are capable.

Thanks for the interest in this, trial @ChrisB @deanjames

For me to get you added to our list of future volunteers (there's currently an ongoing trial using the early volunteers) I'll need a PM with your account number, name and DoB. The details of these future trials are unconfirmed.

Currently we're sending our new In Home Displays, and building an API, to allow the volunteers access to their usage data for their own smart home integrations. We are then collecting feedback from them as it progresses.

I'm sorry for the lack of contact about future trials @sam_cat - we appreciate your support and patience, and will be in contact when we know more details.

Would it be possible to add a feature to analyse the gas smart meter data against the degree day data for my area.

This is a widely used tool to analyse the energy efficiency of building heating, as it allows usage to be normalised against the weather.
Hi

I like the 'Your Energy Breakdown' not sure how much I trust the breakdown.

Since January 2017 we have plugged our Audi e-tron PHEV into our home electricity and since mid January we have used a POD Point charger. Neither have ever showed in the counts of 'Electric Vehicle'.

At the end of September, I let OVO know. But as yet the only response has been an email saying 'have a lovely Sunday' . And a follow up email saying 'How did we do' - I gave prompt feedback but did not get an acknowledgement.

Anyway, are you certain that 'Electric Vehicle' in 'Your Energy Breakdown' works.

I'm also interested in joining the early access program for the API. At present I'm using Loopenergy to monitor my gas and electric usage, and couple that with my Honeywell Evohome heating controller, I've got a fairly good monitor of overall usage and trends. At present I've a series of python scripts collecting data from both platforms and storing the metrics in an influxdb setup which I query and visualise graphically using grafana. I've also developed custom methods for adapting the overall control of the central heating system beyond what the controller already performs, adapting dynamically to usage patterns, weather, and overall energy consumption, for example, if gas usage increases without heat being called across any zone of the heating system, then the assumption is that the cooker is on and the heating then scales back on the upper floors to allow the increase in ambient temperature from the cooker to be taken into account. Plus I just like seeing what's going on (In work with some fairly big data platforms with work so it's kind of second nature really)

So yes, I'm hoping I can continue to collect data from the new smart meter and continue to use it how I do!
Hi, Your use of Loopenergy and Evo is very impressive. I would like to understand why access to a OVO API would bring advantage over your current setup. Surely that will only give you the same data as you have now?

The loopenergy devices are a good approximation of usage but not 100% accurate I find (gas isn't far off, electricity cost estimates are around £10 to £15 off each month though). Plus with moving to a smart meter, the gasloop device will no longer be compatible with it.

Having access directly to the usage data the smart meters are recording would give much greater accuracy on my usage, which will give me much greater visibility on patterns of usage. This would be especially true with the gas usage, as at present Loopenergy only gives usage data every 15 minutes.
+1 for this – or at least being able to download your raw data to be able to analyse and explore ourselves. Would be really useful and interesting.

Hi all,

It's great to see so much engagement and I can tell there's a lot of interest in live usage data and all the possibilities that go with it! There's a good few queries which I'll try my best to answer, but make sure to help each other out - that's what the forum's for!

Would it be possible to add a feature to analyse the gas smart meter data against the degree day data for my area.

This is a widely used tool to analyse the energy efficiency of building heating, as it allows usage to be normalised against the weather.


Well, @jadam, overlaying weather data over gas consumption data is something we've thought about and we may consider it in the future, as the benefits are obvious!

Sp @DaveJenYearsley for an electric vehicle usage to show,you will need to create an appliance profile. For your info, here is a screen recording of how this works:



Hope this helps,

Hi,

I’d be really interested in getting access to the data via your API. Could you please add me to this?

Many thanks,

Simon
I’d be keen to get involved with any early access program. I specifically am interested in writing a Skill for Amazon Alexa to retrieve my usage data. For example being able to verbally ask how much I spent on energy and/or am currently spending would be really useful.
Hi,

I too would be interested in being part of the trial and accessing my raw data via the API. How do I sign up?

Adam
I would also like to sign up for trial access to raw data.
Can you stick me on that list to? Quite fancy getting my Alexa in on the action 😉
I'd also be interested in this. Was planning to create a https://homeassistant.io component as soon as the API is available. @Tim_OVO I'll be sending you a pm shortly.

Sorry, I know I'm jumping the gun... but I'm:

a) Impatient
b) Curious

I've spent about an hour messing about to try and aggregate the realtime metrics for my Smartmeter usage, and although somewhat inconclusive (due to gaps in data going back to ovo it seems). I've done some reading up on how the SmartThings integration points work, and between that and some trial and error, got a small python script up & running which will log in, poll for active smartmeters on the account, and check the instant usage data against them (if present):

vagrant@vagrant:~/Scripts# ./ovo.py
Getting readings for GAS meter with mpan 7********4:
Estimated Annual Usage is 7144 M3
Demand : 11.693 KW
Cost/Hour: 0.3776839
Getting readings for ELECTRICITY meter with mpan 1********3:
Estimated Annual Usage is 7091.1 KWH
Demand : 2.564 KW
Cost/Hour: 0.3610112

I'm looking now at doing historical polling, so aggregating data over a set period of time, which seems easy enough to do as it's just serialised JSON in the results for example:

{"power":[{"startTime":1513036800000,"instantPower":0.8766,"tariff":0.1408,"price":0.12342528},{"startTime":1513036860000,"instantPower":0.8114,"tariff":0.1408,"price":0.11424512},{"startTime":1513036920000,"instantPower":0.8276,"tariff":0.1408,"price":0.11652608},{"startTime":1513036980000,"instantPower":0.8102,"tariff":0.1408,"price":0.11407616},{"startTime":1513037040000,"instantPower":1.6943,"tariff":0.1408,"price":0.23855744},{"startTime":1513037100000,"dataError":"NotFound"},{"startTime":1513037160000,"dataError":"NotFound"},{"startTime":1513037220000,"dataError":"NotFound"},{"startTime":1513037280000,"dataError":"NotFound"},{"startTime":1513037340000,"instantPower":1.6696,"tariff":0.1408,"price":0.23507968},{"startTime":1513037400000,"instantPower":1.7693,"tariff":0.1408,"price":0.24911744},{"startTime":1513037460000,"instantPower":1.8,"tariff":0.1408,"price":0.25344},{"startTime":1513037520000,"instantPower":1.9155,"tariff":0.1408,"price":0.26970240},{"startTime":1513037580000,"dataError":"NotFound"},{"startTime":1513037640000,"dataError":"NotFound"},{"startTime":1513037700000,"instantPower":0.7824,"tariff":0.1408,"price":0.11016192},{"startTime":1513037760000,"instantPower":0.7688,"tariff":0.1408,"price":0.10824704},{"startTime":1513037820000,"dataError":"NotFound"},{"startTime":1513037880000,"dataError":"NotFound"},{"startTime":1513037940000,"instantPower":0.8776,"tariff":0.1408,"price":0.12356608},{"startTime":1513038000000,"instantPower":0.7783,"tariff":0.1408,"price":0.10958464},{"startTime":1513038060000,"dataError":"NotFound"},{"startTime":1513038120000,"dataError":"NotFound"},{"startTime":1513038180000,"dataError":"NotFound"},{"startTime":1513038240000,"dataError":"NotFound"},{"startTime":1513038300000,"instantPower":0.8985,"tariff":0.1408,"price":0.12650880},{"startTime":1513038360000,"instantPower":0.833,"tariff":0.1408,"price":0.1172864},{"startTime":1513038420000,"instantPower":0.8089,"tariff":0.1408,"price":0.11389312},{"startTime":1513038480000,"instantPower":0.7962,"tariff":0.1408,"price":0.11210496}]}

I just wish that the signal from the meter was more reliable so not to have gaps in the metrics... (hence the NotFound events)

During the coneversations with rep when I was enquiring about a SMART meter I asked if I would be able to download the readings which had been sent.

It is now six plus months further on and there is no sight of this on the main web site.

THEREFORE I WAS LIED TO.

Can this feature (which surely must be in the pipeline otherwise I would not have been told it was possible) be implenmented as soon as possible.

Hi @blakedrayson @MikeWilliams

At the moment, we only make available the monthly meter readings that are sent for your statement. This are available via My OVO here: http://ovoener.gy/myovo.

To be part of possible future trials which makes available your smart meter data (a trial is already in progress), send me a PM with your name, account number and DoB. I can't promise anything at the moment so I'm sorry if you were promised this feature as standard.

@ErTnEc, this is exactly what I want to be able to do. I use NodeRED to poll darksky.net for current weather readings. Can you send me your python script to play with?
Userlevel 2
You already have an internal RESTful API that your node.js framework uses for callbacks withing the Usage page et al. And this JSON return is all that you need for a Node RED flow.

However doing the page request to establish a valid session token is a bit of a PITA. It's a pity that you don;t faciliate direct access to your /api/live/meters/NNNNN/consumptions/aggregate read functions using a secret api key approach that many such system use.

Nonetheless, I'd rare do this the "approved " way, so can you sign me up for trials? Thanks.
Hey guys

@Tim_OVO I'm a smarthome developer and log term ovo customer. It would be great to get involved in this trial!
