Hi Ryan,

great work on your Sous-Vide topic. Some ideas / nice to haves:

• it would be great to set a temperature profile - i.e. xx F for 300 min, xy F for 400 min etc. - for 3-5 periods, with a final zone that is kept constant
• it would be great to visualize the ON / OFF in the graph to verify the proper functioning of the PID
• it would be great to have the graph just continue to plot right from the start (or after a reset) - so taht one can see what happend with the temperature.

I am still new to the programming , I worked a bit through your code, but I have to admit, these points (and the used libraries) show me my limits.. ;-)

BTW - any reason why you did build your own PID instead of the standard PID library of Brett Beauregard?

Best Timmo

I am unable to set a target temperature or turn off the system from the home screen. As a workaround, I can use the recipes and reboot the device to turn off. Also, at the end of the cook time, does the device stop holding temperature?

I can get it to boot up and appear as an access point named Sous Vide however if I try to connect to it via an Android device or a Mac desktop, it eventually crashes like so:

setup complete.

I'm using the most recent versions of the required libraries via the Arduino library manager.

Hi,
at first thank you very much for the project. I was just thinking about a diy sous vide solution and then found this project.

From your experience ... does it have to switch the relais very quickly on and off or is it more like a minute on, then off, a minute on, then off and so on?

I'm asking because I'm wondering if it would be possible to replace the relais with a SonOff basic switch (5$) connected to the cooking device running Tasmota or so. This way it could be turned on by wifi or mqtt and there wouldn't be any physical connection between the temperature sensor connected to the esp8266 controller and the actual switch controlling the cooker. There would probably a delay of a second or two everytime it has to switch.

I compile cketch and upload it to wemos d1 mini. It seems working but the webpage of esp still reloading and there no any data on the screen of the webpage. What is wrong?

I'm also looking into what it would take to get this on an ESP board that only has 1024k of flash, can you think of a way to slim it down so that it would all fit? If not, what would have to be cut?

Arduino: 1.8.13 (Linux), Board: "LOLIN(WEMOS) D1 mini Pro, 80 MHz, Flash, Legacy (new can return nullptr), All SSL ciphers (most compatible), 16MB (FS:14MB OTA:~1019KB), v2 Lower Memory, Disabled, None, All Flash Contents, 115200"

This report would have more information with
"Show verbose output during compilation"
option enabled in File -> Preferences.

I couldn't get this to work until I completely erased the flash memory on my ESP8266 using esptool. Without doing that, it would boot up and log "setup complete" on the console but the wifi part would not load. I suspect before loading this project, something had already written to the memory in the chip and when the network code in this project attempted to read persisted data, it failed in some way that prevented it from fully loading. Perhaps there is a way to fix that?

But in the meantime, if anyone else is stuck, just clear the firmware memory completely using esptool before flashing this project.

Thanks!

Hello, I am unfamiliar with angular, I have tried to follow some tutorials online with no success... How do I run the webserver?

After updating Chrome and Edge, I have such a message after connecting to ESP as attached.
Help on how to fix this problem.

Hi,

Thanks for your project. It is great!

https://learn.adafruit.com/sous-vide-powered-by-arduino-the-sous-viduino/sous-vide is a similar project and it offers a way to auto tune the PDI settings.

I saw that you hardcoded your settings, could you share some advice on how to determine correct settings / tune the PID for my cooker?

Regards

After updating Google Chrome, the control interface stopped working. However, under Microsoft Edge this problem does not occur.

Dear Ryan,

The PowerOff seems to throw an "undefined" in the browser. I am not deep into angular (acually just learning it whily tring to modify your scripts), but somehow this seems to be undefined in the core.js file.

any hint? thx!
