Please forgive me if this is covered in documentation that I have yet to read. I’m using multiple esp32’s and I’m able to on-board them to ESPHome. However, I’m not sure how to add the C code that I have written to accept data from my pinouts. For example, Adafruit soil sensors, gps boards, etc…
I found a post within these forums where there is a good code example (or better than mine) but on information on where that custom C is places for access in the configuration.yaml.
Sorry for the noob question and I hope someone out there is kind enough to lead me in the proper direction.
Read about generic custom C components for esphome here…
But heed that big warning at the top. You should probably find another way to do it. Port the code into esphome perhaps?
What are you trying to do? I ask because you’re riding the line on an X/Y problem. (telling us what you want to do without context on what you’re trying to accomplish while your method may not be correct for the platform and leading you down a rabbit hole.)
Thanks for the resource. Before I take a read, I’m trying to automate my garden (seems to be a common topic on the internet) but at scale.
I have 6 3x10 beds where I’d like to put a moisture sensor every 2 or so feet. I’m using general esp32s with the Adafruit soil sensor. This sensor is connected to 2 digital outputs and I’m leveraging the wifi capabilities of the esp32 to report into ESPHome. I’ll continue on with remote water control, pump control, etc.
Been reading your post and moved on to contributing code. I think this is the path I want to take. And maybe when I’m done, y’all can include in in the base installation. I also like the option of external code reference with GIt so I’m not dorking around with local files and can share for troubleshooting with the community.
I’m going to start setting up a dev evn as soon as I’m done with my coffee.
Thanks for opening a new thread! Much appreciated!
In addition to what was already said, there might be an interesting project, where you could “steal” some ideas! It’s not particularly an irrigation control, it’s a growroom control (you might get that from the forum where it’s made )
I wanted to introduce that script in a seperate thread, but hadn’t have the time to do so: Note: This is not my script and I’m not taking any credit for it! I’m not the author!
Nope, no git whatsoever… That’s the problem, that the author doesn’t want to expose himself in connection with this script… I do know, that the author has more than one Github repo, but these are probably connected to his employer…you get the idea
The forum thread is the only place to get it, and to look for changes, sorry! I can tag you, when I present the script here in this forum, this thread will be updated. And I already have the permission to do so (you can find it somewhere in that thread) and will try to find the time in the next weeks.
@nickrout thanks for the data, this will help with the watering but not with the moisture sensor. I’m trying to bend my brain around c coding without much success. However, I’m still willing to try and share the repo for hits, tricks, and code addition.
Well, I’m doing my best to create this add-on for the adafruit sensor (w22515-c stemma soil sensor) but something is not working. I took information and code samples from the b-parasite, and I2C sensor like the one I’m trying to import. I created a fork on the ESPHome dev branch and add my own branch here: esphome/esphome/components/w22515-c at adafruit_soil_sensor · FreRange/esphome · GitHub
