Hey gang.
I’m just gonna post this here, to gauge if there’s any interest.
I’ve written this grow room/tent automation software. It runs on a cheap $15 raspberry pi zero (microcomputer). It interfaces with many inexpensive off-the shelf bluetooth devices (hygrometers, soil sensors, power outlets)
A lot of it does things similar to what you’ve already seen from other smart-apps, but there’s a few important differences.
- For security, none of its info goes through the cloud. It all stays in your home.
- Because it is not internet/cloud based (like most WiFi smart devices are), even if you lose internet the system keeps working.
- Smart controls over bluetooth outlets. In other words, use a measurement (like, humidity) from another device to tell the power outlet when to turn off and on. Great for controlling temperatures, humidity, or VPD.
- All device interfaces are based on plugins. If you are tech-savvy, you can write your own plugins for new bluetooth devices, or GPIO device interface on the raspberry pi.
The Main Dashboard
Shows the latest Temp/Humidity/VPD of the room.
View devices in the room
Power outlet devices can have On/OFF Schedules or Smart Controls, to automate fans, irrigation, etc.
Clicking on any of the values will let you see graphs and trends
Set up Smart Controls for Power Outlets
In this example, we set the controls to keep the room humidity between 55-60%. When the humidity gets too high, the fan is turned ON to pull in fresh dry air. After the humidity is at 55%, the fan turns off.
Rooms have a logbook
Keep notes about when you switch to 12/12, or when sprouts were germinated, etc.
Devices I have currently written plugins for:
- Xiaomi MJ-HT hygrometer
- Xiaomi Mi Flora soil sensor
- Govee Hygrometers
- Oria Thermobeacon hygrometers
- Govee H5080 bluetooth power outlet
- Govee H5082 Dual outlet power
- SwitchBot Hygrometer
- Switchbot Plus Hygrometer
Is this the sort of thing the community would be interested in?
