Most of the Sainsmart relay boards have relays that can trigger on either 5V or 3v3 and have a built in optocoupler that allows a signal to switch a (separate) power supply that powers the relay. If you leave the jumper connected, then you're powering the relay off the 3v3 line which means that the controller's on-board voltage regulator is effectively powering the relay. This is the main issue -- the strain on the controller's voltage regulator.
Uhhhhhhhhhhh.... I don't recall why I added that note. Maybe because I hadn't vetted the component list? Regardless, the design works great, and is the primary design I recommend for new builds.
So much of my design revolves around upgrade paths for existing users.
Of course, I'll need to get a fermenter that can use glycol first!I guess I wasn't very clear--leaving aside the "official" D32 pro TFT display with its cable, what should I be looking for, and how would I connect it? Nothing of what I'm seeing on eBay has a matching connector, so it isn't quite clear what I should be shopping for.
Understood. Should I keep a given controller with a given fermenter, i.e., controller 1 with fermenter A? Or is there no particular reason to do that?
OH! Sorry about that. The overwhelming majority of the TFTs out there that are compatible have the same row of pin headers on the back. To help break it out, I created this PCB. That changes the pins from being in a row to a 2x5 pin box header. You can then use a ribbon cable to connect the TFT to the controller.
OK, a single row of pins is a lot closer to what I'd seen. Does it need to be 320x240 (that's the bulk of what I'd seen)? Given an appropriate resolution, I don't suppose the physical size really matters.
There is a parameter in the setting under Configure Control Constants that sets max fridge temperature. You will need to increase that.
Very strange about the degree sign. Pretty sure that works on my end but I’ll have to recheck when I’m next near hardware.

Well, I'm pretty sure that is just mine LCD not your code.
For me to have degree sign I need to make my custom character or use in the code: lcd.print(temp_A + (char)210 + "C"); to have something similar to degree sign like on attached picture

I got VSCode + Platformio and I did compiled some other projects (the one on the picture for example).
I got problems with BrewPi-ESP and I think it is windows system specific.
Here is output from VSC terminal after build attempt:

You can see here build for esp8266_wifi but that is because I did try different things to make it work. When it was esp32_wifi_tft result was the same.

Boards are here, complete with SMT assembly. I've built up two of the boards, and plugged an ESP and a 2004 I2C LCD into one of them--it flashes fine, talks to the display fine, comes up on the network fine. Don't have it talking to temp sensors yet, but that should be soon (there isn't a problem, just haven't gotten to it yet). I've ordered some of the "backpack" boards from oshpark along with TFT displays (and boards for your "magic box" optocoupler circuit), but those will be a while yet. Progress, progress.
That probably will be silly question.
Is iSpindel calibration necessary?
I set up fake brew for testing fermentrack, and SG shown on chart is unreal.
View attachment 832054
But I didn't make iSpindel calibration. I just took polynomial equation from iSpindel setup page and pasted values into iSpindel's configuration page at fermentrack:
Current Formula: gravity = 0.0x^3+- 0.00031x^2+0.557x+14.054
So back to original question. Do I have to perform calibration or there is something wrong with my iSpindel (when I did iSpindle pure water calibration, angles shown in info page was OK to me)?
EDIT:
OK. I know I have to calibrate my iSpindel
I play a little bit with formula calculator and inserted different equation to fermentrack and now it looks way better.
I'll get working on it. Just importing the EAGLE files into KiCad is leaving some odd artifacts, so I'm thinking I'll need to re-draw them. May take a little while, but I'll put in a PR when they're ready.
I got my first BrewPi-ESP controller put together this morning, complete with this optocoupler circuit. As expected after last week's testing, the ESP turns the chiller pump on and off as desired. I've set it up to run a beer profile in about 10 gal of water; I'll see how it goes over the next couple of days.
