Oh geez that vid is worrying. Good to know for my project.
Luckily I’m on regulated 5v so first two issues don’t apply (didn’t check for issue) and my design seems to be clear of the third.
I’ve also given mine the nail polish treatment.
Forgot to mention, that I have uploaded the new version to git now. The old one is still there too.
I cannot see it, last update on your GitHub repo is 21 days ago.
Thanks, much more clear! But still unsure which sensor we are talking about. What link are you referring to?
I pressed the commit but not the push button. Git takes a bit of getting used to, I guess. Have another look now.
This is the one:
DIY Capacitive Water Level Sensor using ESP32 Touch Read function - YouTube
There is work going on for ESP-home support for it as well I believe: ESPHome GPIO Touch Sensor as Capacitive Input for Waterlevel - #6 by mulcmu
Also, where did you find the 5 mil laminate sheets for DIY sensor? What I find seems way over priced.
Good question. I had the same thought while I worked on it, but just assumed they had been there all along, and not giving them much thought while focusing on other parts. But they haven’t. I’ll get rid of them and re-upload.
I just had some lying around. I am not sure what they are. As I understand capacitors, the thinner isolator (it’s called the dielectric, right?) the better. I haven’t tested mine yet.
Are any arguments given for the increased thickness wherever you saw the requirement?
One of the holes must be for refilling the water?
In the video he mentioned 0.5 mm make the sensor stronger. Maybe we don’t it that strength, I don’t know.
No we don’t need it. I think he needs his sensor to be a little stiff, but we don’t.
The two mysterious holes are gone now. Complex models made by someone who only almost know what he is doing have a tendency to behave in funny ways.

Anyone here have any updates?
Its been two weeks since the last post, I am just wondering how everyone is getting on?
Anything that you guys can report back on and let us know of?
Anything I can do to help? (I don’t know how to code, (other than python) sorry.)
Thx!

I am still working on it. Next step for me has been to test the new version of the physical parts.
I’ve been having issues with my 3d printer, hence the silence, but now I’m rolling again. I’m getting rid of the last bugs in the design, by printing small portions of it. Hopefully I can start the first full print in a few days.
The next things that needs doing are almost exclusively coding, I think.
Btw. if you can code Python you can surely code Home Assistant Yaml too.
I tried printing your latest model, I could not fit anything in the reservoir hole for the sensor. It was too tight.
I also built the DIY sensor, and it seems to work well. 
No, that was one of my findings as well. I’ve made the big pipe 2mm bigger to fit the tube and the wires. It’s on it’s way out the printer.
Awesome news about the sensor. Did you test it with moist soil as well as water? If not, could you also test how well it measures soild moisture, and if it will do it when mounted as it is in my design?
I’ve uploaded a new version of the pot, but I haven’t made a final test-print of it yet. Will do one of these days.
