True, but that would be a lot more complex and expensive than just using a 1-wire sensor, and i don't see any advantage.for PT100 you can add the RTD Temperature Sensor Amplifier board, I guess a new board would need to be made for both

Have a look at the github wiki there should be enough info to get u started, and just let me know if something is missing!This is just what I've been looking for. I haven't worked much with the ESP32 much but I'm sure I'll figure it out. Trying to build the perfect (for me anyway) one vessel system. So far what you have looks pretty damn good.
Buy a boiler for sparge water and your brewlife / brewday will be easier.This is just what I've been looking for. I haven't worked much with the ESP32 much but I'm sure I'll figure it out. Trying to build the perfect (for me anyway) one vessel system. So far what you have looks pretty damn good.
Yeah, I've been reading through that. I just ordered a board... so I'll know in a couple days if I can figure it out. lolHave a look at the github wiki there should be enough info to get u started, and just let me know if something is missing!
Yeah, I have all that figure out. I own a brewery which I'm currently selling.... this is my basement retirement system! Have a 15 gallon 3 vessel, but I'm looking to simplify and design something custom for me.Buy a boiler for sparge water and your brewlife / brewday will be easier.
You do own a 3.3V usb to serial and some jumper wires?, you need that to flash the board.Yeah, I've been reading through that. I just ordered a board... so I'll know in a couple days if I can figure it out. lol

Yeah good idea, i think there is nothing about the serial connection on the wiki atm!Jeroen maybe some info that you could add to your Wiki page?
Do you mean use the teensy as a usb-serial adapter?, or run esp brew engine on esp?Would the teensy work by any chance
I know it’s a stupid question but in place of the esp32 use the teensy board then add hardware as needed, I know the code will have to be changed, it has better memoryYeah good idea, i think there is nothing about the serial connection on the wiki atm!

I do now. Like I said, I've worked a little with arduino and Pi but im by now means an pro. I was able to get the board hooked up and connected to the loader, but I just can seem to figure out which file I need to load. I have looked and tried several. Im sure it's something simple I'm missing, but I could really use a little guidance. Any help would be appreciated. Don't assume I know anything, I won't be offended.You do own a 3.3V usb to serial and some jumper wires?, you need that to flash the board.
Did you get it going in the end?I do now. Like I said, I've worked a little with arduino and Pi but im by now means an pro.

Unfortunately, not. The only way I could connect to the flash tool was with the USB cable the ESP32 came with. It goes directly to the USB-C port and has a "boot" button. It appeared to download something but it does not show up on my WIFI list. Using the connections with the serial device I bought (I have 2 different ones) did not seem to want to connect to the flash tool. I connected the jumpers to the Tx, Rx, GND and the 3.3v pins (4 wires total) and it never connected.Did you get it going in the end?
If you used the same board that Jeroen used, did you use the jumper to connect GPIO0 to GND? see my reply here above.Unfortunately, not.

I am afraid ESP8266 isn't supported, atm only ESP32 is supported, ESP8266 is quite old and doesn't support the ESP-IDF framework so i am afraid it will never be supported.Do you have any idea how to resolve the issue?
Thanks for the fast response. Then I need to order an ESP32 device and wait until arrives.I am afraid ESP8266 isn't supported, atm only ESP32 is supported, ESP8266 is quite old and doesn't support the ESP-IDF framework so i am afraid it will never be supported.
You can set it manual by just disabling AP mode and setting SSID and password , you could also try to decrease the power it might help, i heard some boards have issue at max power setting.Managed to install the system on an ESP32. I have also managed to replace the NTC temp sensor with a 1-wire component. The threaded metal housing of the original sensor was very thin. Drilled out the analog component and ground the case of the DS18B20 to fit into the 4mm hole. Beleive or not, it is working.
Nevertheless, I have an issue with wifi scan. It finds no SSID. Should I try set the router's SSID manually?
It depdens on the browser, in linux you have to install some extra packages to enable it, try googling speech api linuxHow does speech work? Only "none" is selectable in the voice drop down menu. How can I add a voice?
It uses the language configured in the browser, atm there is no option to overwrite that.Thanks. It was a temporary fault with one browser. After a while it worked again. Strange.
Another question. I can see language files but no option to select language on the web UI. Is it missing or did I miss something?
I presume you mean some kind of auto PID calibration?, we don't have that atm but it is something that could indeed be useful, PID is quite complex to configure correctly, but creating a good auto PID is also a challenge.Is there any way to calibrate temperature process?
Good idea, i see you also created a github discussion/ideawould it be possible to add a second smaller pot for sparge water. That your software controls.
Not auto PID. Temperature correction might be more accurate. The DS18B20 in my experience can give diffrent temp values between diffrent probes. So if it's possible to take measurements with a know good source to find a correction value for each probe. According to spec it should be calibrated to +- 0.5 C at factory but that's not my experience. Any tested several probes in real life to see how they perform.I presume you mean some kind of auto PID calibration?, we don't have that atm but it is something that could indeed be useful, PID is quite complex to configure correctly, but creating a good auto PID is also a challenge.
Good idea, i see you also created a github discussion/ideaso if it it on the list i will consider adding it if i find the time.
