Selfcheck: Check if things are correct and send data?

[kyrreso]

Hi, for new users its hard to setup.

I upload and hang mine on the wall, and refresh the sensor page furious to find out if it works, waiting for next time the data is sent. I am not sure if its correct setup, or works, so what i want is: 1: After 5 minutes it sends data

• Wifi works / how well it is / how many issues
• sensor is connected / gets power / runs
• Sensor works -Libraries are installed -what version is installed

This should be done once a week, and the user should see if "selfcheck" worked last time on their sensor site on platform.

Later it could also notify the user if anything fails.
