check out ledgardener's "automating your grow with home assistant" youtube series. He basically uses a rasberry pi, ph meter and periscopic pumps to create a ph controller. Will probs work out cheaper and allows for you to automate other aspects in the future using that platform :)

Hey mate, I'm in the process of doing the exact same thing!

I've set up automation for my humidifier and exhaust fan and am just about to purchase the components for a ph controller. I think im going to grab the Atlas scientific EZO ph circuit & Voltage isolator, use my existing blue lab probe, and then buy an ESP32 and peristaltic pumps for DFRobot.

What components did you use?

Teyleten Robot Mini 4CH 4 Channel Motor Drive Driver
12V DC DIY Peristaltic Liquid Pump Dosing Pump
Screw Terminal Block Breakout Module Board for ESP32-DevKitC
ESP32-DevKitC core Board ESP32 Development Board ESP32-
Mini PCI U.FL to SMA Female Connector Antenna WiFi Pigtail
Junction Box with Mounting Plate
Atlas Scientific pH Kit 0-14 pH

I wish i had used a esp8266 instead of the ESP32
something like the huzzah-esp8266 just because the 8266 runs Tasmota and the version for the 32 is bata
I run through ESPHome its the poop for a controller and sensor dats not so much for calibrating or for a console
Tasmota 9.2 supports EZO sensors
I have a couple of the Atlas Scientific hydro kits flashed with Tasmota 9.2 they both have the huzzah-esp8266
I love em

I will say i started with the Milwaukee ph controller which is a piece of crap
I wish i had gotten the blue labs

ps
while coding the software and doing the wiring make sure to able to do reverse on the pumps as well you
nead to clear the line sometimes
also if i can help i will

I have the blue lab ph controller and really like it. I really had a hard time shelling out that much money but just couldn't stop my pH from crashing.

I purchased one from a very nice gentleman from this site. Gave me a great deal and it works wonderfully glad I went the route I did.

I disagree with you guys. I've been there, tried to do everything lowcost with arduinos and chinese probes.

BlueLab quality and consistency is wayyyyyyy higher than any DIY project except you spent a lot of money on components (AtlasScientific is good enough for DIY).

If you want to avoid headaches and problems, go for BlueLab or similar brands
