Subscription Extras

upgrade.png Octopus Watch comes with an optional subscription that unlocks a number of powerful new features. These features help you plan your consumption better to save more on Agile. The subscription is available as both a monthly (£1.29) and a yearly option (£8.99).

Rate Predictions

Ever wondered what the future may hold? With the rate predictions you can see what the rates are for the next 24h (accurate) or 48h (less accurate), even if the rates are not available yet from Octopus Energy.

Rate predictions can help you plan your day better. Ever pondered whether you should quickly do another load of laundry between noon and 4PM, or wait for better prices overnight? Using the predicted rates you can quickly get an estimate of what overnight prices will be.

Predictions are continuously updated to provide you with the most accurate estimates. A total of 4 models are used, each requiring more data yet providing more robust predictions. This makes it possible to provide you with an idea of what the prices will be as much as 48h in advance, while still providing prices you can rely on for the next 12-24h. The predictions you see in the app are always the latest and most reliable prices known at that time. In general, predictions are updated roughly every 5-15 minutes.

Predictions can change!

Rate predictions are just that; a prediction. Their accuracy increases closer towards 4PM as electricity availability and weather data stabilises. Predictions can provide an invaluable benefit when used as a tool to plan your usage.

How predictions are shown and used is up to you. The Options screen has a dedicated section for predictions. To use predictions you need to enable the Show Predicted Rates option. The slot finder can also use the predicted rates to find the best slot by toggling on Use Predictions for Slots. To ensure that you don’t overpay the slot finder only uses the reliable 24h predictions.

The new predictions engine used by Octopus Watch 3 can not only predict the rates for the next 48h, but can also predict the range in which prices will fall. Since predicted rates can fluctuate due to changing weather, power plant failures, etc. the predicted prices can go up and down with time as more information becomes available. To still help you decide in the longer term Octopus Watch now has the option to Show Chance of Better Slots. Whenever Octopus Watch thinks there could be a better slot if you wait a bit longer the app will tell you so. The confidence intervals are used to make this decision and Octopus Watch will tell you on the slot finder card when there is a low, medium, or high chance of better rates if you wait another day to use electricity.

If you are not on the Agile tariff, you can still choose to see the Agile predictions along with the prices for the tariff you are currently on. To do so, enable the option Always Show Agile Predictions.

Finally, if you also have export, you can now also get export predictions. To see export predictions make sure you have the option Show Export on Rates Tab turned on, as well as option Show Export Predictions.

Predictions can change!

Predictions for the day after tomorrow rely heavily on weather forecasts. Similar to how weather forecasts can turn out to be unreliable — particularly during stormy weather — the 48h rate predictions can be unreliable when the weather is erratic.

CO2 Integration

With the CO2 integration you can see an estimate of the carbon impact of every upcoming half hour, find slots with the lowest carbon impact, and see a summary of your carbon footprint based on your usage data. These values are obtained through a service run by the National Grid. Whitepapers provided by the Carbon Intensity service and detailing how the national and regional values are calculated are available through the links.

To see the impact and fuel composition of an upcoming half hour slot you can tap on any row in the Upcoming Rates Table on the Rates tab. This opens a new screen where you can select whether you want to see either the national or region carbon intensity as well as a pie chart that shows you the energy composition for that half hour. The pie chart is interactive; you can tap any slice to see further details such as the percentage and the type of fuel.

CO2 integration also extends into the detailed reporting, which is discussed in the next section.

If desired, the best slot to minimise your carbon footprint for running appliances can be found. There are two ways to active this mode. You can tap the current unit rate banner at the top of the Rates to switch to CO2 priority mode. Alternatively, you can toggle the CO2 priority mode in the Options screen found in the Settings tab. This screen furthermore allows you to select whether you prefer to use the national or the regional CO2 levels. When CO2 priority mode is enabled the slider on the Rates page helps you to quickly find the best slot to minimise your carbom impact. Furthermore, an extra line chart is shown with the CO2 values for the next 24h or 48h. pro_co2graph.png

Turning Off CO2 Information

Not interested in CO2 information? You can hide it throughout the app. To do so, go to the Options screen in Settings and enable the option Hide All CO2 Data.

Detailed Reporting

Detailed reporting allows you to both see more daily details, and to generate comprehensive energy reports. To see the daily details you can tap on the respective row in the History screen for which you want to see the details.

The page that opens shows you:

  • a graph with both your usage as well as the Octopus Agile rate for each half hour slot;
  • various additional statistics such as your baseload and the CO2 emissions for your usage;
  • the national/regional fuel composition for your electricity usage;
  • estimates of the unit rate and cost for the Go tariff if you are currently on Agile, or vice versa.

Agile/Go Comparison

Agile/Go comparison information is only available if you have version 3 of Octopus Watch, if you have the option enabled in the Options screen to perform an Agile/Go comparison, and if you currently are on either Agile or Go (Faster).

If you also have export the overview is different and provides you:

  • the same graph that now includes both your electricity import and export, as well as your import and export unit rates;
  • your net import/export and your net cost/gain;
  • statistics related to your electricity import;
  • statistics related to your electricty export.

CO2 information is shown in the same way as discussed above. The CO2 information always relates to the electricity you imported and does not take your export into account. day_report_export.png

Tap the graph to see the details of your electricty consumption. The screens that opens shows, for each half hour slot, your consumption in kWh and the applicable unit rate. If you also have export this information will be further broken down to show both your import and export.

Tip

You can long press on the unit cost on the right hand side to switch to cost in pounds. Long press again to switch back to the unit cost. Showing your savings or savings percentage is not possible when you also have an export meter.

Energy Reports

As part of the detailed reporting you can generate as many energy reports as you want, for any time period over the last 4 months. To do so, tap the button in the top right corner of the History tab.

day_header.png

The screen that pops up allows you to select a date range for the report. If you want, you can save the start date for easy access to subsequent monthly reports in the future. Tap Generate (iOS) or Create energy report (Android) when you are happy with the selected date range.

report.pdf

The generated report summarises your energy consumption for the selected date range.

  • New in V3: If you currently are on an Agile or Go tariff, and if you have Agile/Go comparison enabled in theoptions, the generated report shows you an estimate of how much you would have paid on each tariff for the chosen date range.
  • The graph shows, for every half hour, your average consumption and the average Agile Octopus unit rate. The vertical error lines indicate the spread of the average consumption. A long line means that, for this particular half hour, you sometimes have very high and very low consumption. Very short lines indicate that your consumption at this half hour is typically the same.
    Info

    A good usage pattern for Agile Octopus has low consumption bars during 4PM–7PM as well as low error lines during 4PM–7PM. In addition you want to see long error lines overnight and from noon–4PM when prices tend to be lowest.

  • Octopus Watch analyses your usage and can tell you if your usage and/or costs are going up or down during the selected date range.
  • Your average unit rate and standing charge is calculated to make it easy to compare the prices you pay on Agile Octopus with the prices on most other tariffs.
  • New in V3: The report shows your factual unit rate. This is the net price you paid for each kWh consumed – this is higher than your unit rate as it includes your standing charge.
Info

Baseload calculations are inaccurate if you have electricity generation or electricity storage installed. If you have an active export meter then this section will not be shown. If you did not add your export meter during setup, but you have generation or storage, then the baseload number you see here is likely wrong.

Info

Agile vs Go comparisons rely on baseload calculations to give accurate results. If you have an export meter the report cannot show you how much you would have paid on the other smart tariff.

New in V3.1: For every report that spans 2 or more days there is an additional infographic page. The infographic provides you an ever deeper insight in your usage. Full documentarion on the infographic and its various components can be found on the dedicated page.

Extra Options

A number of extra options are available in the Options screen found in the Settings tab for users who subscribe. Most of these options relate to extra functionality unlocked with the subscription. Some options, such as Include Standing Charge and Highlight Cheapest in Table, are only available to subscribers. Other options, such as Export CSV include additional data for subscribers. The functionality of these extra options is described in the Options screen itself.

Extra Functionality

New functionality is continuously added to Octopus Watch. Some of these features are still under development. This includes the notifications, which are currently trickling into the apps on both iOS and Android. Read on to find out how notifications work on the different platforms and how they can simplify your life.

Rate Notifications

Since v2.2.0 the Octopus Watch app can notify you when new rates are released by Octopus Energy. As a subscriber you can opt to only be notified on days when rates drop below a given price. To do so go to the Settings tab, tap on Options, then enable the option Notify on New Rates. The slider below can be dragged from left to right to pick the desired unit rate. Drag the slider to the far right to receive notifications on all days.

android_notification_setting.png ios_notification_setting.png

Warning

On iOS don’t forget to tap on Done to make sure the settings are enabled.

As soon as new rates become avaible and these are are at or below the indicated unit rate you will receive a notification. This notification includes the average, lowest, and highest unit rate, as well as the longest slot where rates drop below the desired unit rate.

notification_android.png notification_ios.png

Extra iOS Notifications

On iOS the app can notify you when a cheapest slot starts. This makes it easy to save electricty for those appliances that do not have timers. To activate the notification tap on the bell icon on the right of the slot finder. After you confirm the notification it will be triggered at the designated time.

Extra Android Notifications

On Android the app can show a persistent notification with the current rate. This way, regardless of which app you are using, the app can keep you up-to-date on the current rate.

notification_status.png

The value within the circle in the status bar shows the rounded down rate. The circle itself indicates whether the current rate is within the 25% cheapest rates for the next 24h, the 50% cheapest, the 50% most expensive, or the 25% most expensive. This corresponds, respectively, with one, two, three, or four filled quadrants.

notification_circles.png

Depending on the version of Android you are using the same icon notification can be shown on the lock screen (when using a Pixel phone or a Pixel Experience ROM), or it displays a more elaborate notification that also includes the next current rate.

notification_lock.png

Info

Notifications are a default component in Android. The Options screen in the Settings tap provides you easy access to the configuration options for the notifications. If you use Do not disturb mode you may want to give the notification the ability to be shown even when Do not disturb is turned on. This way you can see the rate at all times. The rate notification will never use sounds or vibrate your phone.

Support Development

Can you believe it took close to a year of continuous work to get Octopus Watch to the app it is right now? It’s been a great journey, but at the end of the day everyone likes to get paid for their work. And there is no better way to show your appreciation than to subscribe! A full year is less than the price of one month of a standard Netflix subscription. Or three coffees in your favourite coffee place. Yet it means so much to me. It gives me a steady income – Thanks ! It shows that you love the app – Thanks ! And it gives me the chance to continue developing and maintaining the app – Thanks !
