Registering your cylinder, configuring settings and monitoring everything from hot water levels to energy consumption.
The Mixergy App enables you to get the most out of your Mixergy cylinder. Whether you want to set schedules, monitor use or intgrate a smart tariff, the App is there to help you. Some key features of the App include:
- See the available hot water and give a boost when needed.
- Monitor the hot water levels and energy consumption of your hot water cylinder over time
- Set a heating schedule, integrate a smart tariff and make use of machine learning to optimise your system
Downloading the Mixergy App
The step is to download the Mixergy App. This can be done from the Apple App Store or Google Play
The Mixergy App will require you to create an account upon first use. Once your account has been created, you will be asked to register your tank.
Don't use a smartphone?
If you don't use a smartphone or prefer to use another device, you can access most of the same functions through our mixergy.io website.
Registering your tank
Once you've created your profile, you'll be asked to add a cylinder. To do this, you'll be asked for some information.
Mixdevice code
This is a 25-character identifier unique to your tank. It will look like this: mixdevice-xxxxx-xxxxx-xxxxx-xxxxx-xxxxx. You can enter this manually or use the QR code label on your cylinder.
Automatic schedule control
Choose whether you want to use Automatic schedule control. This enables our machine learning algorithm to optimise your schedule based on use. This will monitor your hot water use, consider a smart tariff (if integrated) and refine your schedule to bemore efficient; saving you both energy and money.
You will be given the following options:
- Off: your schedule will not be adjusted, and you must manually schedule your tank.
- Standard (with Grid Assistance): your tank will be conservative in its scheduling, aiming to save some money whilst minimising the chance that you'll run out of hot water.
- Economy (with Grid Assistance): your tank will optimise its schedule to maximise savings. This comes with an increased risk of running out of hot water if your household uses more than estimated.
- Grid Assistance Only: This require a manual schedule but will enable the Grid Assistance Feature. This is a Demand-Side-Response (DSR) feature that aims to help stabilize and maintain the balance of the electrical grid, typically by adjusting their power usage based on grid demands.
This setting can been changed later through by selecting 'Tank settings' in the top menu on the App or the tab on Mixergy.io.
Heating profile
This determines your main heat source.
- Electric
- Indirect (e.g gas boiler)
- Heat pump
This setting can be changed later.
Once the required settings are in place, your cylinder is ready to go.
Using the App
Home screen
The homescreen has three key areas:
- Hot Water: Click here to go to your tank. From there you will be able to see and boost your hot water levels, manage settings and see consumption data.
- Device Management: Detectand connect to your tank.
- Inbox: Here you will find notifications such as feature updates, customer service messages and tank specific information.
View your hot water level
The home screen shows the current heating status of your tank and how much water is available.
The Hot Water Level is the percentage of usable hot water in the tank.
In this example, 59% of the water in the tank is usable hot water (the red portion of the graph), and the remaining 41% is considered cold (the blue portion).
The Heating Status tells you if the tank is currently heating or not. If it is heating, it will state where the instruction has come from. For example, whether it's in response to a boost (from the internet or gauge), due to a user-defined heating schedule, demand side response, or a water sterilisation cycle.
Below the Heating Status it will say what time Mixergy servers last received the water measurements. This information can be helpful when diagnosing internet connection issues in the home.
Boosting your tank
To boost your tank to heat more water, drag the slider on the right up with your finger to the desired level and let go. The green portion of the graph represents the level your tank is heating to, and the heating status below will change. The red portion will climb as the tank heats up until the target hot water level is reached. To cancel a boost made from the App, click Cancel Boost.
Setting a manual heating schedule
Click on the Schedule tab at the bottom of the page and press the + button to set when and how much you want your tank to heat. Click Save to view your new schedule.
You can set a different schedule for each day or copy the same schedule over to several days. You can also set the tank to maintain between a minimum and maximum level – this means that if the hot water level falls below the minimum hot water level, the tank will automatically turn back on again until the maximum level is reached. If no maintain parameter is set, the usable hot water will naturally cool off unless it is first used by a draw event.
For example, a schedule can be set every weekday to heat in the morning at 06:00 up to 80%, and then again at 18:00 to 40%. The initial heat to 80% in the morning should provide enough water to cover all morning showers, with a second boost in the evening in anticipation of another shower or bath, for example.
On the weekends, it could be that everyone is expected to be in the house all day and likely to be using hot water at different times. Therefore, a schedule can be set to heat at 08:00 to 70%. Then a maintain parameter is set to ensure between 15-25% usable hot water is always available throughout the rest of the day.
If you do not set a schedule yourself, your tank will automatically run on a 'default schedule' until you do. This setting will heat your tank to 100% every day at 3am. This may be useful to begin with if you are unsure of how much hot water your household requires, but please note that this may not be the most efficient setting to optimise on energy/cost!
Please note, the minimum hot water level your tank can heat to will be approx.
~40% for indirect tanks and 20% for direct tanks (this will be slightly different
depending on tank size). After this initial heat, you will be able to heat in 1%
increments.
Vacation mode
Vacation mode will stop your tank heating when you are away, and any schedule currently set will be ignored until your return day. To enter vacation dates, click the aeroplane icon on the tool bar.
Setting your heat source
Click the Heat Sources tab to specify which heat sources you want to use to heat your tank.
Set which Default Heat Source you'd like to use to heat your water This will be used for all heating (boosting or scheduling), unless a Custom Heat Source is selected to run for a certain time of day. For example, you may wish to use electricity for heating during off-peak Economy 7 hours when electricity is cheap, and by gas outside of these hours.
You can set a custom source by clicking Add Heat Source on the toolbar. Select from Electric and Indirect (e.g. gas/oil/biomass).
Please note: If available, your tank will automatically utilise any surpluses of solar thermal or PV, regardless of the heat sources selected in this tab.
Viewing hot water usage
Click the Measurements tab to view graphs visualising your hot water usage and electricity consumption. You can see graphs of previous days by clicking Pick Date underneath the graph.
You can see how these graphs are consistent with the set heating schedule and reflect water usage and natural cooling of the water throughout the day.
For example, in the hot water level graph you can see the hot water level rising to 70% at 01:30, as per the schedule. Just after 18:00, the water level dropped below 18%. As the tank's schedule was set to maintain between 18% and 35%, the tank automatically boosted itself to 35%. This worked out well for the user as shortly afterwards there was a large draw event, and without this boost there wouldn't have been enough hot water available.
Swipe right to see the Power graph. This shows how much power was used by the immersion heater (if heating by electric). In this example, there are three spikes, one at 01:30, and another one after 18:00 and 20:00. This is what you'd expected to see from looking at the heating schedule and hot water levels.
Calculation of energy usage and cost
The Mixergy App can calculate how much energy you've used to heat your water, and provide an estimate of how much this has cost. Click the Energy tab, and depending on which heat source you use, select either Electricity or Indirect. Then click Set Tariff.
If you are heating electrically, enter your peak/off-peak electricity prices for an estimation.
If you are heating via an indirect source, enter your tariff price and the capacity of your tank (in litres – this is written on the label on the front of your tank!). If you know the efficiency of your indirect heat source, enter this here for the most accurate price estimate. If you do not know the efficiency, a default rating of 80% efficiency will be set.
