What size res do you usually use for a 4x 4?

Well a days research and I’ve got the following list of things I want my raspberry pi to control.
It’s a lot... not sure wether I can get a single raspberry pi to do all this or if I need multiple yet
Co2 sensor
Co2 burner relay
Humidity sensor
Air Temp sensor
Flower res Fill Water pump relay
Flower res Drain water pump relay
Solenoid Valve 1 relay
Solenoid Valve 2 relay
Solenoid Valve 3 relay
Electric heater relay
Dehumidifier relay
Humidifier relay
Flower res Water temp sensor
Flower res chiller coil solenoid relay
Mother res water temp sensor
Mother res chiller coil solenoid relay
Mother res fill water relay
Mother res drain water relay
Clone res water temp sensor
Clone res chiller coil solenoid relay
Clone res mister relay
Foliar feed pump relay
AC fan relay
Mother res ec sensor
Flower res ec sensor
Mother res ph sensor

My prototype is here. https://www.rollitup.org/t/mycodo.993710/
I have been using it in production for nearly a year and the only issue I have had has been 2 failed relays. The Pi and software itself run perfectly. You need to know some Python to get the most out of Mycodo. I am currently building a new one but this time using Home Assistant as it is more flexible and have it running using MQQT and also can use Node Red for the automation which is nice too.
Edit: Screenshot of the environment, can see when lights come on at 06:00
I think you will be fine to run that many sensors and relays on one Pi. The Pi 4 has a decent proceccor and 4GB Ram. You may need a breakout board of some type as you might run out of GPIO ports for the relays but thats not too hard. Home Assistant willl also support many more inputs (sensors etc) that Mycodo as well.

Yes no feedings at lights off but I feed right at lights on.
Yeah I’ve been reading a lot about it.
I think the issue I will have is sensors are analogue and id have some sensors 10m away from pi, 9m away 5m away etc and they don’t work over that distance from what I’ve read
I may have to look into if it’s possible to use cheaper ardunios which alll sync to the pi?

You could run multiple arduinos, I know with home assistant it is possible to go that route. HA is good like that, lots of flexibility.
I will be going Wifi for all my sensors. I have temp / humidity already running with a Sonoff TH10 flashed with Tasmota over MQQT.
For CO2 there is a good cheap option that uses ESPHome and home assistant:
MH-Z19 CO_2 and Temperature Sensor
Instructions for setting up MH-Z19 CO2 and temperature sensors
esphome.io
What options for CO2 sensor?
Yes, it works very well with ESPHome and Home Assistant esphome: name: co2sensor platform: ESP8266 board: d1_mini_pro wifi: fast_connect: true domain: .local power_save_mode: NONE reboot_timeout: 5min ssid: "mySSID" password: !secret use_address: co2sensor.local # Enable...
community.home-assistant.io
This is why I am going HA for my new build, the community support is huge
Yeah after a quick search after you first mentioned it earlier today I decided home assistant was best option.You could run multiple arduinos, I know with home assistant it is possible to go that route. HA is good like that, lots of flexibility.

The arduino would just be the sensor right? Providing the data to the pi and the pi does the computation for eg co2 < 1200 turn on burner

Yes, multiple ways to do it. Usually I need to choose the option that my limited skills can achieve lol
Yeah I have some programming experience from uni years ago but haven’t done anything since
Just figured I’d start breaking down the list into sections where the sensors will be close by and I got
Air environment ardunio
Co2 sensor
Co2 burner relay
Humidity sensor
Dehumidifier relay
Humidifier relay
Air Temp sensor
Ac relay
Electric heater relay
But then I think to myself what’s the point of home assistant if that arduino controls the environment?

Web interface, access when away from your LAN, logging, charts, customizable dashboard, community support, open source etc is why I like it. You could go a different route for sure, its personal preference in the end.

Is home assistant something I just haven't heard of or are you meaning Home automation?You could run multiple arduinos, I know with home assistant it is possible to go that route. HA is good like that, lots of flexibility.

Yeah exactly its just using home automation tech to control a grow room. Instead of turning your kitchen light on and off you are turning your grow lights on and off etc.

Have not looked into that but yes looks good. So many options there is always a way to get the job done

Nute burn. Always happens when running multiple strains some are heavier feeders some lighter.
Edit: For test runs I always start out at ~1.0 EC then go to 1.4 EC when I boost the PK. Thats usually when you get the burn but not always, some plants lap it up. Then just back off again for the remainder of the run tapering off to virtually plain water by the end. Thats how I do it anyway for seed plants.
