Once you have your setup or once you’ve build your own GreenThumb will be ready to integrate providing automated controls and notifications with visual and sensory insight into your systems.

If you have any questions or are interested in the project or using my open-source packages, feel free to leave a comment or ping me on LinkedIn or Twitter, I will be responsive.

GreenThumb is also seeking early clients, partners, and initial funding. Yes, I did the work and paid for this all on my own.
