Who this is for: operators watching the network, engineers keeping it running, and analysts working with the data.
Before you start: you are signed in (Getting started). Everyone can use the map, the node pages and the table; exporting needs the Analyst role or above (People and access).
Map: where is it bad?
Map shows every node in your organisation, coloured by the value of one channel. A city network starts on the air-quality index; otherwise the map starts on PM2.5. Pick another Channel and the map recolours.
- Open alerts are marked on their nodes.
- Stale and offline nodes are drawn grey. They are never hidden, so a node that stopped reporting still shows where it is.
- Zoomed out, nearby nodes merge into one marker that shows how many there are and the worst value among them. Zoom in to separate them.
- Hover over a node to see its current value; click it to open its page.
Filters narrow the map by site, kind, status and alert state. Basemap switches what is under the nodes: Dark, Light, Mid-tone or Satellite. Legend explains the colours.
Node page: what is happening here?
The top of a node's page answers the first questions about it: its name, kind, site and status, how it is powered, how it is connected, when it was last heard from, and its % valid data for the period you choose.
% valid data is the share of the readings the node should have sent in the period that arrived and were not suspect. It counts each local day of the site, only from the day the node was adopted, and only over the channels the node reports. When the node sent nothing at all in the period, it shows as empty, never as 0%.
Below that:
- One card per channel, with its current value, its unit and a small trend for the last hour. A value older than the node's reporting interval shows its age and is greyed, so an old reading never looks current.
- Charts of any channel over 24 hours, 7 days or 30 days, with several channels on one chart if you want them, and alert periods shaded.
- The alert history of the node.
- Details: its install date, position and hardware identifiers.
Table: which ones?
Nodes opens a table of every node with its current value in every channel. Sort or filter by any column, with the same channel and site filters as the map.
Choose a period and the table shows each node's average over that period in every channel, with its % valid data.
Export table downloads exactly what you see as CSV, followed by each node's air-quality index: its number and category, headed with the version of the index's method. A node without an index leaves those columns blank.
Export everything
For the full record, Export raw readings prepares every reading of one site over a period you choose: the last 24 hours, 7, 30 or 90 days. It comes as two CSV files: the readings, and the % valid data for each node and channel.
The export is prepared in the background. You will find it in your menu, with the date it stays available until. Exports are complete and in open formats. If your organisation has used its exports for the day, the page says so.
