Yep! I'm not sure if they have a PC application. But you can connect with your phone and pull data that way. Coupling with Mycodo is my general recommendation

Those MiFlora look great too. I have an Adafruit soil temp/humidity sensor but it doesnt have BLE onboard so I never got around to using it yet.
Only question is the first Gearbest site says they are discontinued?
I know. What a bummer. I found some on ebay and amazon. Little expensive though.
I'd love a BLE sensor to measure soil moisture...
I've moved to Wemos D1 Mini units for my production grow tents. I've also wired in several sensors that guard my house and property. Here's a collection of a few various sensors while I'm in transition:
Again, that's a collection of various sensors only. It does not depict all of them.
My "breach" sensors alert me via text and email (with camera motion) when things move when they shouldn't. Also, I have a significant 120V alarm sound when my house is breached. Since I live on a lake, the alarm isn't something a B&E person wants to hear as they come within 15" of any window or entry point. If the audible doesn't bust ear drums, it'll send shock waves.

What software are you using? Very nice!

(edited to add - I will re-read all of this thread now that I will be able to understand more of it - I realize some of my questions are covered here! thanks for your patience)
Would love a nudge in the right direction from some of the experts here. I am VERY new (2 days) to Arduino. My first "project" was to try and use nodemcu with bme280 to get the data output to local a webpage (one of the wesbites I used https://lastminuteengineers.com/bme280-esp8266-weather-station)
LOL. I didn't realize the bme280 had to be soldered to the header pins, you would have laughed seeing me wondering why my first attempts weren't working with the bme just balancing on header pins in a breadboard. haha. So yesterday I did my first attempt at soldering, and got the basic project working. its been hanging all night in my tent, and I've been comparing to my INKBIRD (temp/humidity controller) and generic device. (aside - now I want to take the inkbird and my generic device apart to see what sensors they use... I would guess possibly the less accurate dht11 or 22)
next - DATA LOGGING. Please help me. I started googling this last night, and see there are many different ways to approach. Onboard sd card storage, more complex web servers etc. For my setup - my nodemcu are in my house on local wifi. all i need to do is log the basic data (could my pc on local network do this instead of the added cost and hassle of putting a sd card on the nodemcu?). I am good with excel, and for the time being would be content just to get a log of the data so I can graph and analyze. I plan to add multiple sensors in different rooms.
What is the easiest/cheapest way to log this data (keeping in mind I want to build up to 10 sensors)?
other quick easy questions I plan to go on to google right now - please add if you have expert thoughts;
- best way to power these little units
- cheap ways to mount/contain them
- any issues i'll run into with multiple bme280? I see that two can be run on one nodemcu by changing address on one to 0x77, but I suspect I will have a separate nodemcu for each sensor.
Thanks in advance!

Ok I re-read the thread, and learned most of you are doing way more than I am after right now, and I am not sure I saw a "cheap and cheerful" way to log data for my application.
After posting the last time, I was thinking that perhaps I could just get excel to ping the local ip address of the nodemcu (on wifi) and pull the data at set intervals. I will look into that but would love to hear from any of you.

I'm just getting started using a raspberry pi with various sensors to monitor my grow room, but would like to leverage the rpi to control temp/humidity and to switch the lights, but am obviously getting into high power territory. Which relays are you folks using to switch high power devices; e.g. heater, lights, etc.

In case you haven't figured out a solution yet, I am just having the ucontroller join the network and send a udp packet to broadcast. A script listens on a separate device and writes any data received to file or displays it. There are many udp libraries for android if you want phone display - idk the name of the drag and drop one offhand, where you don't need to know programming. Mit inventor or something.
Choose normally open (lights) or normally closed (fans) as necessary for failsafing?

Look back on page one of this thread. I'm still using those/these 30 amp/240Vac relays.
Even though they both have 30A relays, I use the big one with it's own 5Vdc power supply and the cover over the 25 Vac rated connectors, not the smaller one with the 5Vac connectors. I get 5 at a time from AliExpress or Bangood if I don't mind waiting a few weeks for delivery. If I need one right away, there's always Amazon. If I remember correctly, the high output signal from the Pi is 3.3 Vdc. That will be enough to turn these relays on without even though they normally require 5Vdc. I'm using them with both ESP-8266s and 32s, both outputting 3.3 Vdc high signals, and have had no problems. If you do have problems, put a 3.3Vdc to 5Vdc logic level converter in between the Pi and the relay. Good Luck.

Describe your hardware, software and network if you need help with webserver. I would just change the output in the sample code to a html page with a table and scrape it into excel.

i sign for the mycodo... its amazing! it has data logging included, here is a link to blog about it:
Automated Hydroponic System Build – Projects | Kyle Gabriel
kylegabriel.com
and to github page:
Mycodo
Documentation for Mycodo, an open source environmental monitoring and regulation system.
kizniche.github.io
very, very capable machine!
im also doing my own automation system, but ill be using nodes with one master, sensor node for air temp and humidity, co2 and leaf temp near canopy, relay node for controlling vents, humidifier and dehumidifier, heater, (ac will keep outer temps lower, so if i need lower temp i just pull one from room), all pid tuned of course, with nutrient doser which would be mix of these ones:
and light node for my custom led lights, with spectrum picker and supplement light management (uvr8 t12 bulbs 15 min on 15 min off for xy duration), ir light after main light for 10 mins for that emmerson effect (and longer main light), all connected to openHab user interface module with data logging for some future ai shit... hope this sparks some ideas and put you on good track! happy growing <3

I love this, I've been wanting to do something similar myself due to my love for technology. I'm fairly familiar with computer programming due to my work as a developer, but I'm completely in the dark about Arduino. I do have a Pi I use to emulate old games, but I think it would be better off for this. My eyes will definitely be on this. I did get a pair of bluetooth temperature/hydrgometers in the mail earlier at least, so I'm already getting my foot in the door. My next move is to see if I can set up my old smart phone in the area with them, and maybe even see if the company I bought them from could get me an API key so I can do more with the data.
Had some, hated them. Measuring the top couple inches for moisture was next to worthless. Sticking them into the bottom of the pot maybe.
