Hey all,
Im not a reef guy but you chaps certainly love your DIY dosing! I use Deep Water Culture and in need a of some help with some code for automating the pumps but not using Home Assistant to trigger as if Wifi or HA crashes (which is does sometimes) I want everything to run off the ESP and not having HA trigger dosing times etc, only using HA to alter them.
I am 3D printing a 4 + 4 12v dosing pump housing using the G928 pumps (none affiliate link ). Each box holds 4 of them and then a separate box holds the water temp, pH and EC values along with a few other sensors (not reef related but the rest is).
The pumps are powered by two tb6612fng in each box and also a PCA9685 inside. The PCA9685s then connect to the main box through one another via i2c to the ESP32 in the 3rd box. The PCA9685s is a 16 channel pwm driver which can act like a switch 0% or 100% and the tb6612fng's need to many pins to operate of just one ESP and I didnt want to use multiple ESPs. If you check out this breakout board from Adafruit I got the component idea from them: https://learn.adafruit.com/adafruit-stepper-dc-motor-featherwing:
Im fine with everything but the ESPHome automation side. Any ESPHome gurus able to point me in the right direction?
Many thanks and love looking at your chaps Reefs!
