This is an Arduino Reef Aquarium Controller that integrates with the supplied Vera plugin. Using the Yun’s Bridge to receive HTTP commands and send back sensor data, integrated with Vera, is useful outside of the Aquarium Controller use case. You could use the Yun as a gateway to control LED dimmers for room lighting. I am considering, for my next HA project, using a Yun in each room to handle sensors and dimming, and doing away with the Z-Wave stuff. The level you can get to now with DIY is so good, even with just a few lines of code, that it hardly seems worth paying the premium anymore for the off-the-shelf stuff.
The Arduino Sketch manages:
- 2 channels of PWM controlled lighting
- Temperature monitoring of tank and LED heatsinks
- Temp controlled LED cooling fan
- Kalk Mixer (in the day)
- Kalk delivery (at night)
The associated Vera plugin provides integration of the following features into the Vera dashboard:
- Temperature monitoring (4 devices)
- PWM dimmer level monitoring (2 devices)
- Relay control monitoring (4 devices)
