Using a Raspberri P3 with a DS18 temperature sensor.
Use WEB on Win10 as dashboard.
https://cayenne.mydevices.com/cayenne/dashboard/project/257c24ed-3599-4d0d-b144-ca6b6fa471d3/history
It would appear as if the data storage function for my project don’t work properly.
The sensor DS18B20 widget do register the temperature and the raspberry has been running non-stop for more than 2 days, however, the historical data does not save to the cloud.
If I click on the “Details & Chart” icon for the DS18B20 widget and select the “m” then the graph is displayed.
If I download the chart data then only a few records appear in the sheet. It looks as if it only displays the data for the duration of time that I have been logged in to the web interface.
If I click on the “h” option in the graph a message is displayed “No data available for this period”.
As a test I added the DS18B20 widget to a project to see if that resolves the problem.
The data download option displays the data from the time the DS18B20 widget was added to the project.
When I click on the “Data” option on the blue bar with “Live” selected on the row below a message is displayed “Waiting for the live data…” but nothing seems to happen.
When I click on the “Data” option on the blue bar with “m” selected on the row below an hour glass with blue spinning circle comes up and a message reading “Nothing that matches the criteria”.
Any ideas?
