[released in beta] Yearly Energy Data

Energy IQ is a good start and enables the user to see costs of current months heating cost compared to last months.

Can you add a feature that allows user to look at last years complete monthly data and compare it with current year to date.

Users can then see if changes to their system have made a difference to running costs

    Hi Derek,
    I know that this doesn't actually help with your requested information being available via the tado° App....but you can do your own Spreadsheet and you will get truly accurate information from your own data input, and not a "rough approximation" from whatever algorithm that tado° deems appropriate for "all" it's customers.

    This has become available in beta earlier this week. Assuming no issues arise for the beta users, it means we will make it available to the normal app within a week or two.

    Do note that we do need the heating data for those historical months. So, you can only look back as far as the month you installed tado° at best. Additionally, it's only energy consumption, not energy cost, as the cost per unit of energy has differed greatly over time. Cost estimation will be done for the current month only, for now.

    Hi Derek,
    Did you notice that @Rob stated that it is "energy consumption" and is not directly attributable to "heating" usage.

    Well, it's a heating energy consumption estimation. Could be oil, gas, whatever source you use.

    Hi Rob,
    Sorry to be a bit pedantic, but......
    How does tado° differentiate between.... Hot Water..... Gas Hob/Cooker....Central Heating "Energy Consumption"
    Surely, if tado° is using an algorithm, what "assumptions" are being used to determine the breakdown of specific energy usage for each element.....and how does tado° know how each unique household operates......I don't see how "one size fits all" can be anymore than a "guesstimate"........or is there more specific data available that I am unaware of ?? 🤔
    If there is....can you expand on this so that I can fully understand.

    You need to subscribe to Auto Assist for it to work which I do not need or want! I should have added that I am covered by Green Flag which might make sense to UK Viewers!!

    @GrayDav4276

    It works like this:

    • When you upload your energy data into the tado° app, we know how much energy (whether kWh electricity, m3 gas, litres of oil, ...) you've used between 2 dates.
    • Assuming you've used tado° in the same period, we also know how often/how long you've heated in the same period.
    • We make the assumption that you use your heating-energy-source mostly for heating, and use little of this source for anything else.

    Based on those first two parameters and the assumption of point three we make our calculation and prediction. Very simplistic: If you use your heating 10% less in March than in February, your energy consumption (in kWh, m3, L. Not in £) for heating will have gone down by roughly 10% in the same period as well. In reality the calculation/prediction is a bit more complex, but I guess you get the gist of it.

    We don't take cooking on gas into account, for example, however this is entirely insignificant compared to gas consumption for heating. Hot water consumption is more significant, but even here, assuming you don't take very long hot showers very often, it is relatively insignificant compared to energy consumption for heating a house.

    The prediction we make is the best one available given the limited amount of data we have.

    @Rob,
    I understand what you are saying........but you use the words "assuming and assumptions and predictions"......and then you state.....
    "The prediction we make is the best one available given the limited amount of data we have"
    So, as I said......I don't see how "one size fits all" can be anymore than a "guesstimate"
    I'm still not convinced of the usefulness of this tado° feature.........my spreadsheet gives me accurate figures for my "energy usage"...... obviously, I can't differentiate between Hot Water/Cooking and Heating, but then again I'm not attempting to convince tado° customers to pay for a subscription service. 🤔😎
  • This feature is not working. My system has been isolated from fuel and power and all Tado units are turned off since 1st May. Apparently I have used €89 so far as of 30th May. Complete nonsense and also complete inaction from Tado via email. Fix it or delete it Tado false information on energy is of zero use to anyone.
