How often does loggers upload measurement data to the system?
It depends on the logger type and if the logger is connected to power. Generally CO 03.01/13.01 and CO 03.02/13.02 loggers are used for warehouse monitoring. These loggers uploads measurement data every 10 minutes.
CO 21.01 logger, that are used to monitor stand alone fridges for example, uploads data every 10 minutes if the device is connected to power. If it is not connected to power and runs in Power Saving Mode, it uploads data every 24 hours until the battery level is around 35% (up to 180 days). Then the logger starts to upload data every 48 hours until the battery level is around 5%. (up to 145 days). The logger then uploads data every 96 hours until the battery is empty. Overall, CO 21.01 could, in theory operate up to one year on one battery charge. Cellular signal quality and frequent excursion will effect the battery endurance.
What is "Entity"?
The measurement data can be organized in a hierarchy and categorized according to collection. Each point in the data hierarchy tree is called a Entity. Each entity can be a collection, asset or measuring point.
What is a "Collection"?
A "Collection" is similar as a group in the system and can represent a country, region, city etc.
What is a "Root-Collection"?
Root-Collection is the first or the top collection in the entity tree.
What is a "Sub-Collection"?
A "Sub-Collection(s)" is collection that is under another collection, see picture below
Why are they different sub-types of collections?
Different sub-types of collections changes how the data is shown in the user interface
Collection (Generic)
Collections and assets are shown as a folder structure in the Overview Tab
Area Collection
Show sub-collections or assets on a geographical map
Facility Collection
Gives the option of drawing a schematic of the facility and show current temperature measurements
Do I need to create a complex entity tree to represent sites that I want to monitor?
No, the entity tree can be simple as a group collection. Asset directly under the root collection or skip the root-collection and create asset at the top of the entity tree.
What is an "ASSET"
An "Asset" is an Entity for measuring points that measure the same area. For example a fridge, freezer, aisle in a warehouse etc. Each asset can contain many measuring points. Average, MKT, min and max temperatures are calculated for the Asset
What is an "Measuring Point"
Measuring point collects the measured data from a sensor. Measurement point is given a name that represent the location of the temperature. For example "Shelf A1". A temperature logger measures the temperature and uploads the data to the measurement point. The logger can be replaced without loosing the measurement history.
What is an "Event"
In FMv2, a EVENT is created when the temperature is outside set limits or out of bound i.e. the temperature is too low or too high. When the temperature logger sense that the temperature is outside set limits, the system creates an EVENT to identify abnormal temperature. The EVENT is ON-GOING or ACTIVE while the temperature is out of bound.
What is "Aggregation"
"Aggregation" basically means "a group or mass of distinct or varied things".
