Tips

  1. Remote Control

    The Harvest ITU G2 systems can be used for remote control of equipment from a computer or smartphone, e.g. to turn on/off an irrigation pump - see the screenshot below. This is an internet based control system with immediate on screen acknowledgment, rather than a text message which you cannot be sure if or when it has been received.

    Tip 1

    To find out more about remote control on your property, contact our sales team via sales@harvest.com or +64 370 1991 (freephone 0800 HARVEST).

  2. Growing Degree Days & Richardson Chill Units

    Any Harvest system with at least one air temperature sensor can calculate Growing Degree Days (GDD) and Richardson Chill Units (RCU). The GDD and RCU values are displayed alongside the related sensors' graph (see below) for the time period you are viewing, apart from the current day in progress.

    Tip 2

    To view or change your growing season for GDD/RCU calculations, go to "Login and Settings" in the Options menu of your Harvest Webpage. Then scroll down to "Seasons" and use the drop down menu to change the growing season, then click "Save All Options".

    Tip 2

    To set up your Harvest system to show GDD and RCU, contact our Tech Support team via support@harvest.com or +64 370 1991 (freephone 0800 HARVEST).

    For more information on our Harvest system calculations please visit our system calculations page.

  3. Wet Bulb Temperature

    We can calculate and display wet bulb temperature for any systems with temperature and humidity sensors. Simply ask our Tech Support team to set this up for you. Wet bulb temperature is very useful if you use water for frost protection. When you first start to apply water, the leaf temperature rapidly drops to the wet bulb temperature, so you must be sure that the water is turned on before the wet bulb temperature gets to zero.

    Tip 2

    To set up your Harvest system to calculate wet bulb temperature, contact our Tech Support team via support@harvest.com or +64 370 1991 (freephone 0800 HARVEST).

  4. Localised Forecast

    For any Harvest system with functioning weather sensors, as an add-on service we can push weather data to Weather Underground who then provide a localised forecast based on those readings and their expanding network of personal weather stations. You can read more about how they do this here - Weather Underground Website.

    Tip 4

    To add a localised forecast to your Harvest system, contact our sales team via sales@harvest.com or +64 370 1991 (freephone 0800 HARVEST).

  5. Download Data

    You can download data from your Harvest system in text or CSV format. Here's how:

    Head to your Harvest webpage and under the "Options" menu at the top of the page click "Download Data".

    tip 05 a

    Choose the format, start date and the duration or end date for the period of data you would like to download. The "Split Date/Time" tickbox gives you an option to split the date and time data into two seperate fields.

    tip 05 b

    Use the "Custom Fields" to customise the data you would like to download.

    Logs: If selecting monthly, daily, or hourly logs - options for the minimum, average, maximum or total values for each parameter will appear. You must select at least one of these values.

    tip 05 c

    Summary: Use these tick boxes to include easy-to-read summaries for the parameters selected in the next step.

    tip 05 d

    Columns: Use these tick boxes to specify the parameters you want to download. Each parameter will have it's own column. The default is set to all parameters.

    tip 05 e

    Once you have selected your desired options, click the "Download Data" button at the top of the page and your data should begin to download after a few moments.

    If you have any issues or questions regarding the downloading of data, please contact our Tech Support team on +64 370 1991 or 0800 HARVEST.

  6. Botrytis & Powdery Mildew Risk

    With the right sensors, your Harvest weather station can calculate and display the risk of Botrytis cinerea and powdery mildew.

    The sensors needed for these calculations are a leaf wetness sensor and an air temperature sensor. The Bacchus modelĀ for calculating Botrytis risk was actually developed in NZ by Dr Balasubramaniam (Bala). Click the image below to see live data.

    Please contact us to get these risk models displayed on your website.

    Further information about how we calculate these, plus other calculations possible with the Harvest system can be found atĀ www.harvest.com/support/calculations/.
