Fan contral doesn't like when the sensors aren't there. This just restarts fancontrol once everything is ready to go. There must be a simpler, better solution but this works for now.
Create a file:
sudo vim /lib/systemd/system-sleep/fancontrol #!/bin/sh case "$1" in post) sleep 5 systemctl restart fancontrol.service ;; esac
Make it executable:
sudo chmod +x /lib/systemd/system-sleep/fancontrol
