Will a relay+ESP be the best way to get this kind of precision in duration?.Is it possible to create such automation in HA?.a PC fan (5V?), some magnets and a magnetic mixer, for mixing.a power supply for the ESP device (I have an old phone charger that I could use ideally).a power supply to feed the relay (still need to figure out the convenient model).an ESP32 Node MCU or an ESP8266 (i have a couple of spare Wemos D1 Mini clones that I could use ideally).a 8 channel relay 5V, arduino compatible.8 peristaltic pumps (still need to figure out the voltage).So, I spent the whole day researching and here is the draft I have so far. I normally do this manually, but I need it to be handled automatically, at least when I’m out for vacations. In my case, the minimum duration I will need is 1 second (for 1ml of fertilizer). I learned that some cheap pumps can measure with an acceptable precision the amount of liquid they pull off if there’s a way to control precisely the duration of the time they are switched on. Most of the fertilizers are in a liquid state, except for one, which is thicker, but still a liquid.įertilizers need to be administered with precision. They need to be mixed in the watering water in the moment of watering the plants, not before. The fertilizers I use in my garden are organic, and very perishable. My very first steps on creating an automated watering system with variable and easily perishable fertilizers. Hello, my first post here, I’m really impressed with HA community.
