Problems with display not updating

[ssegruts]

Thank you for all your efforts with this project, it is an excellent project.

I think I have followed everything correctly and I now have the dispay showing the current rate.
However, it doesn't update.
When I SSH in and run the update python3 octoprice_main_inky.py it connects, downloads the current prices and updates the price.

I'm new to programming so really struggling to find the problem with why it won't update.

Cron is set as below:

@reboot sleep 10; cd /home/$USER/octopus-agile-pi-prices; /usr/bin/python3 octoprice_main_inky.py > /home/$USER/cron.log
*/30 * * * * sleep 20; cd /home/$USER/octopus-agile-pi-prices; /usr/bin/python3 octoprice_main_inky.py > /home/$USER/cron.log
05 16 * * * cd /home/$USER/octopus-agile-pi-prices; /usr/bin/python3 store_prices.py -r G -t FLEX-22-11-25 > /home/$USER/cron.log

Edit this file to introduce tasks to be run by cron.

Each task to run has to be defined through a single line

indicating with different fields when the task will be run

and what command to run for the task

To define the time you can provide concrete values for

minute (m), hour (h), day of month (dom), month (mon),

and day of week (dow) or use '*' in these fields (for 'any').

Notice that tasks will be started based on the cron's system

daemon's notion of time and timezones.

Output of the crontab jobs (including errors) is sent through

email to the user the crontab file belongs to (unless redirected).

For example, you can run a backup of all your user accounts

at 5 a.m every week with:

0 5 * * 1 tar -zcf /var/backups/home.tgz /home/

For more information see the manual pages of crontab(5) and cron(8)

m h dom mon dow command

Any help on where to look next much appreciated.
Thanks
