- Date: 19-04-25 Version: V19-04-25-V1B
- Beta Version.
- Working code.
- Thouroughly tested.
- Added enable/disable hooks for LCD, LEDs, STDIO, FAN, Light, Water Atomizer
- Added debug hooks.
- Added temp hysteresis for controlling exhaust fan
- Date: 19-04-30 Version: V19-04-25-V1B
- Beta Version
- Working code
- Thouroughly tested.
- Moved time variables to 'config.py'
- Set initial hi/low values to current values
- Reset hi/low values every day @ midnight
- Date: 19-05-22 Version: V19-05-20-V1B
- Creates folder where values saved from the GROWSS app are stored
- Renamed FAN_HI_HUMID constant to FAN_ON_HUMID to make more sense
- Separate day & nite temp hysteresis for controlling exhaust fan
- Humidity hysteresis for controlling exhaust fan
- Temp & humidity setpoints for Blynk mobile app
- setpoints for temp & humidity control when exhaust fan turns on
- Temp & humidity hysteresis for Blynk mobile app
- Time when lights are on/off for Blynk mobile app
- Date: 20-01-27 Version: V20-01-27
- Simplified version number
- swapped MQ2 density sensor with 2nd soil moisture sensor
- added I2C BME280 temp, humid, & pressure sensor
- modified python code to remove density sensor & add bme280 & moisture sensor.
- modified Blyk mobile app to remove density widgets & add:
- bme280 temp, humid, pressure, hi low temp & humid, hi low moisture, bme280 graphs
- Date: 20-02-02 Version: V20-02-02
- added code to control either humidifier or dehumidifier
- added enable flag to choose between humidifier or dehumidifier
- flag indicates which one (humd or dehumid) is plugged into the relay/outlet
- allows for either to increase humidity during low humidity or decrease humidity during high humidity based on the enable flag
- added code to update atom led on Blynk app to indicate whether the humidifier or dehumidifier is being used
- Date: 20-02-04 Version V20-02-04
- updated humidifier/dehumidifier control code
- added a constant to define @ what RH% the humidifier is enabled/turned on
- added a constant to define @ what RH% the de-humidifier is enabled/turned on
- selects appropriate RH% constant based on if humidifier or de-humidifer is being controlled
This is my design of a GROWbox Supervisor System (GROWSS). The GROWSS system monitors temp, humidty, &soil moisture for 2 potted plants inside a grow box or tent. It also controls the lights, exhaust fan, & hudidifier. An LCD display shows the monitored values.
A Blynk mobile app is used to monitor the values & alert when thre is an alarm present. The GROWSS Blynk mobile app has only been tested on Andriod mobile phone.
The GROWSS system will be used in a 2'x2'x6' grow box, but can be used for other sizes of grow box/cabinet/room/tent.
This design will have many stages until completion. Check documentation in the 'Files' tab above for detailed descriptions of the design.

- Read Temp (temp/humidity sensor)
- Read Humidity (temp/humidity sensor)
- Read Soil Moisture for 2 plants (soil moisture sensor)
- Visual alarms for over/under values of temp/humidity/soil moisture (leds)
- Save information to local storage as a tab delimeted text file.
- Visual Display (LCD Display)
- Increase humidity in grow box if humidity is too low (humidifier)
- Decrease humidity in grow box if humidity is too high (de-humidifier)
- IoT/Web page/mobile device access/control
- Push alarms to me via text/email
- Turn grow lights on/off using RPI (relay)
- Turn on/off fan based on day or nite temp & humidity using RPI (relay)
- Enable/Disable email, text, fan, light, leds, RGB LCD, & atomizer (humidifier)
- Interactive controls for changing env values using blynk app
- Automatically water plant when soil moisture is too low.
- Retain values after a crash or reboot.
- Catch more errors to avoid program crash from broken sensors, etc.
- Enable/Disable email, text, fan, light, & atomizer (humidifier) from Blynk app.
