shit, you should start selling that package, i know id buy one
Nice setup! I am running home assistant as well and its the best thing since sliced bread. I use Ruuvi tags for temp/humidity reading. They use the bosch BME280 that is popular and are in a waterproof plastic puck which is nice for humid grow tent environments like mine. There is a Ruvvi integration in HA and the Ruvvi tags donāt require bluetooth pairing which is nice. As long as you have an esp32 board already in play you just have to hard code the MAC addresses for the tags into your Yaml file and upload it to the esp32 board. So far they have been really good and the readings seem to be consistent.
I have a bunch of smart electric switches that I have my lights plugged into and I control the schedule using Node-Red automations. Same thing with a dehumidifier with triggers set based of the Ruuvi tag readings.
The shit is cool and the sky is the limit if you know some coding. I bet I am all in for less then $400 and I have a system that would have cost over $2000 off the shelf if I bought something like TrolMaster or a true PLC system.
What soil moisture sensor are you using? Automated irrigation is the next automation I want to add to HA.
Also if you are looking at power relays check out the Shelly relays. They are ESP8266 based and are made to be flashed with Tasmoda by having easy access to the pinouts of the board. They also have an integration into HA so alot of people donāt even bother with flashing Tasmoda since the built in firmware is pretty good. They are out of an Eastern European country so not Chinese made hardware like Sonoff. I want to move my lighting off the TP Link smart switches and tie the wifi enabled Shelly relay directly into the power line. I feel like this will be a cleaner connection for power.
I honestly thought about it. But it does require a fair amount of configuration at the end user. Then I remembered my time as a Dell tech, and how some people shouldnāt even own a computer, and had second thoughtsā¦ The problem is that the remote sensors, aka the ESP32 chips, need to be programmed with network access info, the switches need to be linked from a different app, change a switch name slightly and its broken. If there was a truly Plug N Play way I could, Iād consider it. To someone slightly tech savvy, a cut-n-paste programmer, or someone whoās built their own PC, it would be pretty easy to setup. To others, it would be all greek, and lots of people want it to ājust workā.
I bought raw BME280 sensors for the ESP32. The Ruvvi are a nice option though. The BME280 sensors are only a few dollars for a multipack. The co2 sensor cost closer to $20.
I like the idea of one upload to an ESP32 board with the Ruvvi tags, that would solve some issues for a new user to setup, certainly make it a little easier.
All my automations / triggers for the lights and humidifier (and shortly adding the dehumidifier) are in Node-Red as well. Powerful piece of software there once you play a little and realize the flow of it all.
All in here, with all the sensors and switches, including the Pi4 / 4gb that runs it, maybe $150?? ESP32 modules are cheap, most sensors are cheap, the TP Link / Kasa switches werenāt even that expensive. The Pi was probably the most expensive thingā¦ Sure, I can 3D print housings for my ESP32 stuff, thats a big advantage for sureā¦ But even using Ruvvi tags its not cost prohibitive 
Resistive sensors have lots of issues, notably deterioration / degradation of the actual sensor itself. Not worth it.
Nice Dashboard. I love how the charts put into perspective temp / humidity swings, how they interact with each other, with the co2 (for me). My cams are ESP32 cams, but I have Wyze Cam V2.0ās I will be swapping to (the 3.0ās dont have firmware that can be flashed for HA, the V2.0 does). I have a few 120/250v relays for raspberry pi / esp32 here that are simple as wellā¦ Assign the pinouts, connect to an ESP32, and I have an 8 channel relay capable of handling 120v no issuesā¦
The sky and your imagination really are the limit hereā¦ The tools are there, just gotta make the best use of them, thinking outside the box at timesā¦

(105) Automate Your Grow with Home Assistant! - YouTube
I am soil, so some of the parts donāt pertain to me, but the meat and potatoes is thereā¦ Light one up, and start watchingā¦ You can even do one project at a time and add to the system via the videosā¦

Looks like we have a few people here using Home Assistant. I might have to start a thread to consolidate that knowledgeā¦
If you have questions, certainly feel free to askā¦ If I can answer, or know where one is, Iāll shareā¦ I think the hive mind here could figure out most issues 
I like to think of it as an electronic erector set for adults

There is already a garden automation thread and I would love for people to start posting in there to give it life again. Home Assistant running on a Rasberry PI is such an amazing tool every gardener should be using it. I am shocked it doesnāt get more love on this site.

Thanks. The charts for me are worth their weight in gold. I love data points and this gives me amazing understanding of how events that happen in my garden effect the environmental variables. Once I get that understanding I can then take actions to control getting things into the range I want.
I would like to get my AC Infinity fan controlled using PWM with HA and MQTT. From what I have read on Ledgardener site its difficult because the newer gen fans have an EC motor instead of DC and that presents issues. I need to research it a bit more as I donāt full understand why its an issue.
Its SOOOOOO nice having all the information at your fingertips in HA. Add in smart switches, relays and sensors and man you can have total control over your garden.
LEDGardener even has his automation system measuring out and mixing his nutrient batches for him. Cool stuff.

Well you just saved me a lot of work! Thats awesomeā¦ Checking it out nowā¦ And Iām sure Iāll add my own things to itā¦

Please do! We are all working to a common goal with much of the same type of equipment. So if we can all collectively help each other work through the issues along the way it surely helps.
