Grow Room Automation

[AvidLerner]

I am on to another project. I have decided to approach the process with a total approach. So I have been researching automation systems. I settled on openHAB as versatile and reliable and readily available and open source, as well.

So i have set up a raspberry pi 3+ with wifi, bluetooth, and ethernet. I have set up a basic grow setup with three areas of veg, Bloom, and Cloning, each with independent air, water, and light schedule controls that are available to control on any mobile device. here are a few screen shots to wet your lips.

Awesome! I haven't played with a raspberry pi yet, but it's on my list of things to do.
I just got some DHT22's today for an arduino humidity controler I'm planning. I should probably make the jump to pi before I end up with 12 arduinos running different equipment and not communicating with each other.

That looks great

Update:
I have completed re-programming of the ESP8266E development board and connected the board via wifi to my mqtt service, which is a message and transport service, allowing devices to communicate with established criteria on both sides.

I use node-red for development and final transfer to openHAB after all programming is completed and tested.

I am using three relay boards with two 10A/250V or 10A /125V relays. The relays use 5v control to turn the relays on/off. I have programmed the ESP8266 to communicate with both mqtt receiving and sending updates on each relay to node-red which will be openHAB upon final completion.

A single zone will need 6 relays, 1.light, 2.recirculating fan, 3. CO2, 4. F&D/Hydro pump, 5. AC, 6. humidity as well as gathering temperature and humidity data and taking action based on established limits of heating/cooling demands.

The system will run on an a raspberry pi 3+ with 250 gb HDD running openHAB2 and mqtt with access to router for wifi allowing both local and remote access with password protection and no cloud-based activities. All activity is behind the router except when you access with smartphone over internet, otherwise smartphone is inside router, as well. So the system can be run from a smartphone if desired.
