This project contains most everything needed to 3D print, assemble, and flash an ESPHome/MQTT Smart Vent.
Here is a short video demonstration on YouTube.

- It is recommended that you pair this vent with a system that can measure and monitor Delta T (the difference in HVAC return air temperature and supply air temperature). Check out the Delta Tango project.
- It is recommended to install a Static Pressure Regulating Damper, which goes between the return air plenum and the supply air plenum. This damper acts as a bypass and will open or close relative to the backpressure change created by opening and closing vents. This will relieve the majority of the back pressure that is created by closing vents and will help to ensure the longevity of the blower.
- Create 8x14 variation.
- Fix a small bug where ESPHome's Servo Position does not match up with the Servo's Potentiometer's position after physically moving the vent's louvers.
- Investigate power saving options for battery pack use.
- Add functionality to open vent if the central vent control system goes offline.
- Experiment with 12x12 vent.

Pull Requests are always welcome. I would recommend starting with an issue, so that we can discuss viability and implementation.
Feel free to open an issue and I will respond as I have time. The hope is to create a system that gives consumers what they want, your feedback is important.
