it is possible to delay weewx for 45 seconds from boot.

the method depends upon the type of your operating system and configuration

Put this in the file user/extensions.py:

import time

time.sleep(45)

Using the raspbian operating system with latest Buster release. How may it be accomplished on this raspberry pi?Thank you

if you do as Thomas suggested you are changing a weewx file - so weewx will put itself to sleep and give you your delay.  It is not specific to any computer type.

Thomas -

     Is this intended for the file "/var/share/weewx/user/extensions.py" ?  I am running my weewx installation on Ubuntu,

     Thanks!

I hate to ask, but why would you want or need to do that ?

Just curious...

Yes. All files in the 'user' directory are preserved through upgrades, so you don't have to worry about losing the addition if you upgrade. The file user/extensions.py is run before the engine starts up, so it will do they delay before anything else.

Thank you. It worked as described

Just wanted all loading processes to start before weewx and be sure of good network connectivity. It also allows me to to backup of the database before starting weewx with a cron job. Thank you
