[@kumd]

@@LEDGardener Ha, exactly how I feel. It’s certainly a rabbit hole. I have sensors and monitors on things that I don’t really need them on just because I’ve ran out of ideas. I’m tempted to switch to a reservoir system. Do you have a preference or find one to be more accurate between scales or an ultrasonic way of measuring your reservoir? I’m sure they are both good.

[@LEDGardener]

@@kumd The scale will be more accurate. The problem with the scale is that if you have a constant weight on it, it will drift. Mine drifts very slowly though so I just check and recalibrate every few weeks.

[@danp762]

@@LEDGardener How much drift are you getting? How long have you been using them? Is the drift or accuracy getting worse over time?

[@LEDGardener]

@@danp762 I remember checking it a year ago or so - I think it had drifted so it was off by like .25 liters over 6 months or something. The drift does not seem to worsen. I typically had 60 or 70 liters sitting on the scale.

[@wurzermichael]

He’s back!

[@danp762]

I like the videos. Thanks for sharing. I'm doing someting similar with esp32s, a raspiberry pi, and HA. I designed a PCB and had JLCPCB assemble it. It can read 18 moisture sensors, 2 water level switches and output (19) 24 volt AC for watering solenoids or contactors. It has ESD, surge, and overcurrent protection on all inputs/outputs that leave the enclosure. I'm writing the firmware in Arduno. Once, I figured out how to get entries into HA it been pretty easy. I want all my nodes to operate independently. Just in case something goes wrong with the Pi or router. I am planning on using HA as an UI and to notify me if there is a problem. It's been pretty hard finding up to date examples of projects using HA that are easy to follow. It seems they update HA a lot fast than the documentation. Maybe I'm doing it wrong and the is a good place to find good info. I just haven't found it. Is the Raspiberry Pi and HA really reliable enough to run your garden without a fail safe?

[@LEDGardener]

Very cool. HA has been stable in my experience. If it goes down, my garden isn't exactly mission-critical though. From time to time I'll have to reboot my Pi but I'm happy with its performance.

[@danp762]

@@LEDGardener Do you know the reason the Pi is going down? Is it possible to add a esp32 to monitor the MQTT server on the Pi and reset the Pi if it goes down?

[@LEDGardener]

@@danp762 I'm not sure - it's usually just a networking thing I think. Often it can be resolved just be unplugging/plugging the ethernet cable on the Pi. Could be a result of updates or changes I make in HA and it really doesn't happen that often. Maybe a few times in a year. You could program around it pretty easily, like you've suggested.

[@mphatsomtogolo6263]

Bravo man!!!!!!!

[@AudreyRobinel]

Super awesome setup! One thing on sensors: sensiron sht30 and 40 series are considerably more accurate than bme280. I tested any sensors for a long time, including bme280s and bme680s, and the bmes tend to have some shift. Other sensors agree but the BME often is the outlier. Bme680 did not provide very meaningful air quality measurements on top of temp, humidity and pressure, so not worth the extra cash on top of the bme280 price. But in general, sensiron are not much more expensive and more precise. I have co2 sensors to try (from Adafruit, but a bit expensive at 50 bucks a pop). I will post a mini review on your forum when I have some meaningful data to share.

[@LEDGardener]

I really want to try the SCD40 for CO2 monitoring. Wouldn't mind giving the SHT's a go as well but I haven't gotten around to ordering one. Thanks for your input.

[@grotbags4524]

just to add i noticed ruuvi changed from using the BME280 to the sensiron SHTC3

[@Marco9K]

Thanks for sharing! You have come to the same conclusions I have in many cases and I am really impressed that you have gone way beyond what I've done with pumps, magnetic stirrers, custom PCB and the weight sensors for the nutrients. I am on the verge of buying myself a 3D printer myself as what is holding my tinkering back is the lack of enclosures for my gadgets. I have a grow room sensor that uses the same dallas sensor, other sensors for measuring CO2 (my home office is the grow room) , temperature and humidity that I would like to enclose in a nice manner. I am also making a NFT system for lettuce and such but sourcing big reservoirs is challenging where I live, I might need to settle for a smaller one that I need to top up more often. What is your experience with the pH sensor and have you considered including a ec sensor to your system? Also, are you controlling fans, humidity and such in your grow tents?

[@LEDGardener]

I have an Atlas EC probe in my nute mixing reservoir and as I mentioned in the video, I have space to add an EC circuit to each PCB if I can afford them in the future - it'd be nice! I am controlling exhaust fans via PWM and will be humidifying the whole space on a controlled outlet.

The amount of options are pretty overwhelming. I would love to see a video or write up about a budget friendly, basic HA hydro setup. Maybe a video about what you've bought that isn't worth it too.

That looks very promising! I have a suggestion for a future addition to your system: it would be very interesting to track energy and water consumption to measure efficiency. This could be helpful to find optimal values for certain parameters of the system and to compare performance with other agriculture methods. PCB design is a big level up from the older version!

Have you managed to calibrate the Ph sensor from HomeAssistant/ESPHome? As far as I've seen most people use mqtt, or an extra microcontroller to send calibration codes.

I'm tempted to modify the file so I can fire the commands through ESPHome. I built my own custom component in ESPHome for the IR sensors so I think I could pull it off now... it was a hell of a learning curve though.

[@adambadahdah]

How are you using the ultrasonic sensor to measure water level? I’ve been trying to use one to measure water level in the same style tank and I find the echo-y-ness of the tank to give really bad readings. I’m using the one of the waterproof ones.

Really cool, makes me considering buying a 3d printer. And everything so cleanly done, wow. Do you experience wifi to be reliable enough? Did you consider a wired protocol, like ethernet?

I prefer to hardwire when I can, but the WiFi connection for the ESP32s has proven remarkably reliable for me over the past couple years so I saw no need to run cat to each box. I'm not sure which microcontroller I'd use for a wired connection anyway.
