Actually, I found a way (if I don't tell before) to keep our script from sleeping.
How to do that? Just have an uptime robot to PING it every minute.

Our Heroku apps all got an website link to open, from that, we can setup Uptime Robot or other uptime services to ping the Heroku. I found this way from some websites, and it's working with my old script. I don't know how is it now.

last time i used heroku it worked that way . when there is no one accessing the site for certain amount of time it will eventually go to sleep and when i access it again it will boot the script again . uptime robot is a good idea judging from how it works . it basically acting like there is always people accessing it so it never sleep
