I do. Here they are.Welcome to The Farm! Got plant pics?
Thanks for the pics. If that's your first grow, and you're finishing, put it in the win column!
Moderate Ca deficiency (brown spots) and the beginnings of Mg deficiency (interveinal chlorosis). If I'm in soil, I give calmag with every non-feed watering.Thank you! :) Yeah I'm finishing it and many more will come. Those feel like our babies and I feel sad when they are a little sick like this. Any ideas about the problem on the leaves? Should I ask in another topic?

Amazing Work!!
There is any problem to you to show your monitoring system hardware/code?
I'm currently learning about esp32, i just bought one and now im trying to create a monitoring system like yours.
What do you use as server? RaspberryPI?
Thanks in advance, lets growww!!
I'm one of those nefarious salt growers, so I'm not qualified to opine on proper supplementation of an organic grow. It probably needs bat meal or something.Thank you. I thought non-feed watering is not needed when you are using organic, maybe it's a myth. I always fed according to biobizz chart. Do you recommend non-feed watering with calmag in this case or adding calmag in every feed? What would be the schedule?
I kinda feel that non-feed watering makes sense but I'm new and confused. Seeing the improvement on one baby after flush makes me think that non-feed watering may allow the plant to get excessive nutrients in the soil while getting enough water.

Thanks for sharing!!!Thank you Magonheiro! I'm glad that you are interested in the monitoring system and you already completed the first step by buying ESP32. There is absolutely no problem sharing the code. Let's build one for you!
I was already thinking of writing a guide in another post but I can only do it in the weekend. In the meantime, I'd advise you get yourself familiar with the following:
For server, I use a remote Ubuntu machine. I want to access it outside of my home so I just got one from DigitalOcean. It does not matter which device you are using as long as it stays on. You can install it on RaspberryPI and only access it within your home. So this is the easy part, you can decide later. If you got a Ubuntu machine that's reachable within your network, you're ok.
- ESPHome: https://esphome.io/. We are using this project to create the firmware for ESP32/8266. You do not need to look at HomeAssistant integration. We don't use it and we only care about pushing values to a remote server. Learn how it works and try to make sense of its configuration file. Find your sensor component and look at its configuration parameters.
- MQTT. Get yourself familiar with what it is. It's basically a message queue where the device pushes sensor readings. You get the reading from MQTT server and write it to TSDB (Time Series DataBase. In our case, InfluxDB)
- Grafana. This is the main screen. What it does is to query the database (InfluxDB) and create beautiful charts. I already have configs, so you won't have to manually create charts yourself.
- Which sensor are you using? If you got DHT11 (most probably because it's the first sensor everyone gets), I'd suggest you buy SHT31. It's battle tested and DHT11/22 do not work as expected. However, you can use whatever sensor you have for the first iteration, then change it.
- Get yourself familiar with Ubuntu. Learn basic commands (ls, cp, sudo, apt-get, etc).
Let's grow!
I currently work as Cloud Engineer, so im kinda familiar with these things, but i'm really new to IoT World.
About the sensors, for now I have only one DHT22, that will be used to monitor temp/hum outside grow tent, and im looking for alternatives sensors to put inside the grow tent, I found some intersting but Idk if its battle tested as you mentioned
ENS160 + AHT21 - Temp Humidity and CO2 levels.
AM2301
I will check about ESPHome and how to use it without HA integration, thanks to share it, I was struggling with OTA and things to make my development workflow lightness.
I already understood how ESPHome works, yaml is my life as cloud enginerCool! Then I believe you are familiar with the server side. We will be able to quickly setup a DO or AWS instance and start installing the backend components.
Awesome! I will check about it and of course I will follow your experience, buying two new sensors right now! hahaha.There is a good article that tested 4 different temp/humidity sensors. I read it before buying SHT31. It should be saved somewhere. I will try to find and post it.
It’s always a good idea to stick with one sensor because we want to get same reading from the same sensors
I already understood how ESPHome works, yaml is my life as cloud enginer-
Do you know any firmware or anything that I can study about Commercial IoT (I checked/test Blynk but IDK if will fit for this) I mean... my ideia is to make a monitoring system for me, but I would like to create a kind of a product to share with my friends, big deal right? but I want to understand how difficult it is... for now esphome will work!
Awesome! I will check about it and of course I will follow your experience, buying two new sensors right now! hahaha.
Im also curious about how do you connected it into your esp32 and how you placed/builded it inside the tent, how far it is? (sensor x esp)
There is a good article that tested 4 different temp/humidity sensors. I read it before buying SHT31. It should be saved somewhere. I will try to find and post it.
Looking at this graph, and knowing what we've learned from the previous graphs, I would say my preferences for sensors are the HTU21D-F or the SHT31-D. The SHT31-D has a tighter group in this last graph, so if I had to advise people on which temperature/humidity sensor to buy, I would actually recommend the SHT31-D based on the statistics we've seen. This sensor is available in the Adafruit shop for $13.95, which isn't outrageous by any stretch of the imaginatio
