BrewPi@ESP8266, no need of RPI and Arduino.

[pocketmon]

Running BrewPi without RPI would lose the most powerful functions of it, but these will still be available:
Remote LCD display:

Run-Once-and-forget device setting:

Temperature control, include scheduled temperature:


The only thing missed is the beautiful temperature charts, but storing the temperature log is also possible.


This is how the GoogleSheet looks like:

https://docs.google.com/spreadsheets/d/1Zq2vR8DL5Xr_95H6LiLrpHZqwIm9rbvMX84UeI6hhNU/edit?usp=sharing

The data on "bluemoon" sheet is real data from my fermenter in which is fact an IPA, not bluemoon. It has been fermenting for two weeks, so I dare to run the test on it. BTW, I just replaced the Arduino Nano with a NodeMcu board, and it works like a charm.


To reduce resource requirement, jQuery is not used, so the pages look ugly. That is the price for a SD card.

I've just run it for a few days. Therefore, it might still be unstable. Please verify before you put it into real brew. (IMO, enable watchdog timer reset is a better and for now the only way I can think to improve the usability.)

Special thanks to Thorax for the porting of BrewPi to ESP8266, which saves a lot time for me. The BrewPi part is copied from his git.

 

[thekraken]

Subbed!

 

[pocketmon]

Really? Only one person is interested?

Pushing data to thinkspeak.com is easy.

The test data stream is my temperature. It's a hot day today.

[day_trippr]

is this not the same effort described here https://www.homebrewtalk.com/showthread.php?t=586476

if so, seems like this thread should be merged to it...

Cheers!

 

[pocketmon]

not really. I eliminate the RPI while Thorax replaces Arduino with ESP8266.

 

[day_trippr]

Whoops. My bad.
Carry on...

 

[pocketmon]

never mind. I was thinking post in that thread but decided not to hijack his thread.
I started by developing ESP8266 for replacing RPI and thought about porting Arduino code to ESP8266. Just about the time I was going to start, Thorax did it. Then, I just merged his code.

 

[froot]

I'm sure there are more than a few of us keeping an eye on this thread and your development, post count isn't everything. My software skills finish with Dhtml. And seems you've got the hardware wired, and I'm about to move house so no more projects for me till thats done and dusted.

Can this form be used to push data arbitrarily to what ever url is in that URL text box? IE my local ruby web server?

 

[pointcity-homebrew]

Nice project.

I love the ESP8266 module.

I made a wifi mash temp monitor so could watch my temp and not have to keep opening the mash tun and letting heat escape.

 

[pocketmon]

Can this form be used to push data arbitrarily to what ever url is in that URL text box? IE my local ruby web server?

Yes, You can specify any URL as long as it is HTTP, and it is reachable by ESP8266. That is the exact way by which I push data to GoogleSheet.

I wanted to push data to GoogleSheet directly but found out that SSL used too much resource and crashed ESP8266. Then, I changed the code to GET/POST data to a specified URL with specified field names, and setup a PHP script on my NAS as a proxy to push data to Google by HTTPS.

The maximize the flexibility, the filed names can be specified. For example, I use "bt" for BeerTemp in my proxy, and thingspeak.com requires "field1".

I'm starting to think your project will suit me perfectly!

I was looking at your Github readme, in the 'Hardware Setup' there is no mention of the heating actuator?

I don't need heating for now, so I didn't test it.
The other reason is that the left PINs are D0(GOIO16) and D8(GPIO15). On my NodeMcu board, I had trouble using them.
D8(GPIO15) should be pulled down during boot to enable normal boot. Connect D8 to the rotary encoder seems to stop ESP8266 from booting. (sorry, I don't remember what's wrong with D0. )

Anyway, I modified the code to support using D0 and D8 as heater, and they seems to control the LEDs correctly. However, I would suggest not to use D8(GPIO15) if possible. I will update after testing it on my really working setup.

It seems that you don't install OneWire library.
Go to the menu of Arduino IDE
sketch>Import Library > Manage Library
Search "OneWire" and install the library.

I forget which library I downloaded, but the following library is exact the one I have.
You can manually download the library (this is the one in my library path) and put it in your library path.(usually in [user path]/Arduino/libraries/)

So I got the onewire library installed and got another error about SNTP missing. So I downloaded that library as well. This is the next error I get when I verify the sketch. It looks like there is a conflict trying to structure the time. How do I resolve that? If I delete the library "esp8266-SNTPClock" then I get an error for the SNTP includes. What SNTP library are you using?

 

[pocketmon]

Sorry about that.
This is the SNTPClock that I am using.
https://github.com/Juppit/esp8266-SNTPClock

FYI, I couldn't find enough information about SNTP@ESP8266, so I just settled by the first library that I found appropriate. I will go back to this later.

I had issues with D0 as well, but can't remember what they were. I believe it's "output only" - but this should be fine for controlling the heating/cooling side of the relay.

One alternative would be to use OneWire GPIO switches but that would mean more hardware.

I checked my rotary module, a KY-010, and found two of the connection are pulled up. That explains why connecting the rotary to D8(GPIO15) prevents normal booting.

The D0(GPIO16) is a special GPIO which doesn't support PULL-UP but only PULL-DOWN according to this page:
http://blog.falafel.com/programming-gpio-on-the-esp8266-with-nodemcu/

The code in RotoryEncoder.cpp sets the rotary encoder input as INPUT_PULLUP. Maybe that's the reason why it won't work.

If both of D0 and D8 work fine as output, they can be used as heating and buzzer control, which would fulfill my needs.

I checked the library in my library path and found that ESPAsyncWebServer library has been updated.

The version I am using doesn't include <time.h> while what you used does.

I will start to work on this issue. If you can't wait, you can find a version of ESPAsyncWebServer before June 18.

Hi,

First of all great work i am really impressed!!

I sadly cannot get it to work, i have an ESP8266 nodeMCU as sold here: http://www.aliexpress.com/item/New-...265993979.html?spm=2114.13010608.0.103.BD77DW

I have flashed the firmware with their tool as stated here: https://github.com/nodemcu/nodemcu-flasher

Then i added all the libraries as instructed at your github page. In Arduino i setup the board to NodeMCU 1.0 (ESP12-E module)

I doubleclick the BrewPiLess.ino file, choose upload and after the compiling it uploads to my ESP8266 module. After that i saw a Brewpi SSID, so i connected to this and setup so it connects to my own wireless network.
So far so good: the ESP8266 connects to my wireless network, i see in my router that the ESP gets an ipaddress that i can ping. BUT i cannot ping brewpi.local and also when browsing to http://192.168.1.152 (the ipaddress of the ESP) i do not see a webpage (tried in 2 browsers, Chrome gives a blank page, IE gives a webpage not found error)

However as telnet 192.168.1.152 at port 80 works so the ESP is listening at port 80 it just doesn't show anything .

Is there anything i missed ? i wonder if i have to add these library entries into the BrewPiLess.ino file?

I'm not very familair with arduino sketch so i hope you can give some hints

Jan

Per pocketmon I googled "ESP8266 SPIFFS" and came to this github page: https://github.com/esp8266/Arduino/blob/master/doc/filesystem.md
Under the "Uploading to File System" section is a link to this zip file: https://github.com/esp8266/arduino-esp8266fs-plugin/releases/download/0.2.0/ESP8266FS-0.2.0.zip
I installed unzipped this into me $HOME/Arduino/Tools/ directory per instructions from my first link.
From the arduino IDE open the BrewPiLess project and go to Tools -> ESP8266 Sketch Data Upload and it will upload the web page files. This took quite a long time to upload for me. Make sure you're in 'upload mode'. Finally, I had to reset the esp board. Now I'm in business. :rockin:

@pocketmon,
My first feature request would be to have a Celsius Fahrenheit selector.

Looks like the settings is in EepromStructs.h -> line 18, and json info is in JsonKeys.h around line 40 and the function that sets it is in PiLink.cpp line 924. I don't know how this spiffs business works or I'd attempt to make the tweaks my self. (edit) the defaults are defined in TempControl.cpp line 631, I guess as a work around I'll try erasing eeprom and hard coding it to 'F' here.

(edit edit) FYI work around seems to work: I used "esptool -p com3 erase_flash" to wipe it clean and start over, then change TempControl.cpp line 634 from 'C' to 'F'. Reuploaded everything as usual.

If your ESP8266 has the ip 192.168.1.152, browse to
http://192.168.1.152/testcmd.htm


Enter the following string, and "send". Then you have it.

j{"tempFormat":"F"}

 

[thekraken]

Yeah, that would have been a lot easier... lol

 

[thekraken]

So I have 3 ds18b20s plugged in, I can't seem to be able to assign them.

All three show up in the device list and they report their temperature. I assign a device slot and a function and click apply, my terminal reads out "putline:U{"i":"1","c":1,"f":"5","b":0,"h":2,"p":12,"a":"28FF10F76314010B"}" for example. When I go back to the first page nothing is changed.

When I go back to the setup again and refresh the probes are still unassigned.

 

[pocketmon]

would you try Erasing EEPROM? I used to have this issue on my Arduino setup, so I include an ERASE button in the setup page, but I never have this issue on ESP8266.

 

[thekraken]

That seems to have done it, though I had some issues.

First, when I query the list of installed devices the web interface shows that each probe is installed 5 times.

Second, as I was assigning the probes something happened and the esp become unresponsive, even after reboots. I had to reupload the program to get it running.

... and some crazy **** just happened as I was typing just now. The huzzah's upload mode LED came on and I got the following messages in my debug terminal

[pocketmon]

Anything that can go wrong will go wrong.

Make sure your system will restart after crash.

In my career of a software engineer, I always expect bugs. I never expect a bug-free system, but a system survives through bugs. My Arduino BrewPi setup usually crashed in 2~5 days, which might be the result of my bad hardware setup. I didn't have the ability to fix it, either hardware or software, but I managed to add a watchdog timer in BrewPi, so that the system will reset/restart when it freezes. i might have lost temperature control up to 10 minutes for several times, which seems to be nothing to me, to my beer.

I have run this ESP8266 build for three weeks. It was beer constant mode for one week, beer profile mode for cold crash, and fridge constant for 4 days. I guess it might have crashed for 2 or 3 times, because I have a monitoring script which monitors the temperature logging. However, if it will restart after crashing, I am cool with it.

Per pocketmon I googled "ESP8266 SPIFFS" and came to this github page: https://github.com/esp8266/Arduino/blob/master/doc/filesystem.md
Under the "Uploading to File System" section is a link to this zip file: https://github.com/esp8266/arduino-esp8266fs-plugin/releases/download/0.2.0/ESP8266FS-0.2.0.zip
I installed unzipped this into me $HOME/Arduino/Tools/ directory per instructions from my first link.
From the arduino IDE open the BrewPiLess project and go to Tools -> ESP8266 Sketch Data Upload and it will upload the web page files. This took quite a long time to upload for me. Make sure you're in 'upload mode'. Finally, I had to reset the esp board. Now I'm in business. :rockin:

Thanks Guys! i can see the display now! its time to play :rockin:

pocketmon: maybe a good idea to add this to your documentation at github?

keep up the good work!

Anything that can go wrong will go wrong.

Make sure your system will restart after crash.

Well the system failed to recover on it's own this time, I had to intervene.

Besides that I have noticed relatively frequent restarts, at the moment I'm attributing it to my breadboard and questionable power supply. Certainly more than would be acceptable while in use.

Hi,

Got my brewpi on ESP also up and running now cool!!
I have the same issues as Kraken each probe installed 5 times and it also crashes frequently. Hopefully i can find some time today to hookup the relais board and see if that works.

/edit

I have 3 DS18B20 sensors all recognized on the device list and a relaisboard, but it is impossible to install them all. The apply button seems to work 1 time OK for the first device you add, but adding more devices seems to be impossible. Nothing happens and after a refresh (or reboot) you will see the first device like 5 times installed on the same port and function. Is it possible to download the config file from ESP , edit manually and upload it again?

Sorry for being weekend, I don't have much time to respond in detail.

Browse to
http://[your ESP8266 IP]/testcmd.htm
You can issue commands to BrewPi directly and see the response.

The format can be found here:
http://wiki.brewpi.com/index.php/Device_Config_JSON_Format
The command to setup a device is like this:

U{"i":"0","c":"1","b":"0","f":"9","h":"2","p":"14","a":"28F0EBDD0600008B"}

"h" command is used to list all devices:

h{}

No problem!, youre giving usefull info i just cant get it to work yet though i'm very close i think.

When i do

h{}
{"i":-1,"t":0,"c":1,"b":0,"f":0,"h":2,"d":0,"p":12,"a":"28FF593F7415037C","j": 0.000}
{"i":-1,"t":0,"c":1,"b":0,"f":0,"h":2,"d":0,"p":12,"a":"28FF1B447415032A","j": 0.000}
{"i":-1,"t":0,"c":1,"b":0,"f":0,"h":2,"d":0,"p":12,"a":"28FF8774741503F4","j": 0.000}
{"i":-1,"t":0,"c":1,"b":0,"f":0,"h":1,"d":0,"p":15,"x":1}
{"i":-1,"t":0,"c":1,"b":0,"f":0,"h":1,"d":0,"p":0,"x":1}
{"i":-1,"t":0,"c":1,"b":0,"f":0,"h":1,"d":0,"p":16,"x":1}

and then add a sensor:

U:{"i":"1","c":"1","b":"0","f":"9","h":"2","p":"12","a":"28FF593F7415037C"}

After this command alot of data is being generated in the console, but nothing happens afterwards the h{} command show exactly the same again. I tried also without the quotations, with lower case u: etc but no luck.

greetings,

Jan

Ahhh i found the problem

"b":"0"

cannot be 0

this works:

U:{"i":"1","c":"1","b":"1","f":"9","h":"2","p":"12","a":"28FF593F7415037C"}
