Any automatic ph systems?

Check out Taurus hydro they make a device you toss in the water and it keeps the solution within range but lets it drift around within range and way cheaper than a doser unless you get a doser from chewy for aquariums

Build one with 12v peristaltic pumps and H Bridge motor driver. I used to use L298n but recently swapped to a board Adafruit makes which is a PCA9285 with two TB6612 which gives you 4 outputs per board. I also automate my dosing of nutes etc so I first lower the speed of the pump and then coding it for forward and reverse for TIME based calibration. I have also just ordered 8 x HX711 5kg load sensors as each pump has a pipe to a 2 litre glass mason jar. Below the jar is a 90mm PC fan with magnets attached which spin up before dosing and there is food safe magnets in the jars. So once these cheap £3.20ish scales arrive I don’t have to use just time, I can use a combination of weight and time. Having the scales also lets me know how much solution is in each one also.

This is all doable via Home Assistant and ESPHome and I decided to mount the pumps in my main control box. I cannot take credit for this design as it’s based on LEDGardener who was the boss of Home Assistant Hydroponic Automation. I just a changed a few things like using a more efficient motor drivers, only 2 wires to the ESP (i2c) and adding the scales.

I’m using a Gothen 12v G9XX (forgot the last two digits. Run the hole saw (I used a 3in reverse stop plastic cracking and also biting into the plastic as it can REALLY small at you if it’s a decent high torque drill!

Slow and steady! These enclosures are not cheap (this was around £70 without the plastic grill inside.IMG_3567.jpeg

Finished! Just wire to the motors to pumps and keep them tidy.

ESP32-S3 in the middle with 4 motor channels each side sitting on feather triplet or whatever it’s called. When happy, il make my own PCB up using the same components plus the required resistors as il be embedding an ESP32 into my control PCB board:

just watch out for those pumps they basically squeeze the tube to make the sucking.soo after a while the tubes break.

yesh I know that I al aware hence going for the more expensive pumps. They are not as expensive as atlas ones but that’s only because they don’t have integrated motor driver with each one. If I had there pumps I wouldn’t need the motor drivers boards.

That's neat!

Im planning to make a peristaltic pump with an Fysetc E4 board. This has an ESP32 and 4 TMC2209 to drive stepper motors.
How did you integrate the stepper motors into ESPHome? That's the step I havn't figured out yet.

I will pop a thread up soon :)

Keep an eye out at forums.inspectorgrow.com as the board, pumping station etc will be posted soon.

havent seen any updates. id like to get my arduino and my atlas probes to work. how do you sync the esp32 to the home assistant after you have teh probes wired? I cant figure it out. do you run a seperate arduino for each probe

Are there any systems that let you specify a ph.rsnge without breaking the bank? Like if it falls below 5.5 allow it to climb back to 6.0 etc.

I thought.i read about someone using a pool system or fish tank system but can't find the thread anymore.

I use aquarium dosing pumps that have a app. I already had a ph/tds/temp meter and a remote cam to view it so it made sense for me. Not automatic but I look in on it often and it has worked for me. Some people have issues with the app but its worked 100% for me.
$80 each so cost me $320 for up/down on 2 tents.
