Can you wire the pump to a sonoff switch? I like the 4ch pro, it gives you a little room to add more later on if need be.

Flash it with tasmota then you can add that to home assistant

Learn node red as well it’ll help your end game

guess i should also add all these "helpers" are tied into node red using a current state entity node

im using helpers to create a drop down menu for the input of my dosing system.. so here lies the question... is there a way to make a toggle or anything that can switch between a set configuration value to a new one? trying to change a few products ml input when i swap between stages of growth.. mai...

with pumps above liquid also use a one way liquid check valve to maintain the intake flow you require and it doesnt take much effort for the pump to create draw every time its activated

graph the pH value on Home Assistant

use graph card, add sensor your using and it will create graph of its history

double click whatever card you use on lovelace, hass.io will automatically log it for you..unless you want to show it as a display on your dashboard..

jebao 3.4 from amazon
