 # Gravity Monitor for Beer Brewing
 
-This software can be used with iSpindle hardware and utilizes the same hardware configuration. No code has been reused from the iSpindle project. 
+GravityMon is a replacement firmware for the iSpindle firmware. It's 100% compatible with the iSpindle hardware design so it does not require any hardware changes. 
 
-The documenation is now moved to https://mp-se.github.io/gravitymon/index.html
+Now also works with ESP32 (use ESP32 d1 mini which is compatible with ESP8266)
+
+Installation can be made using https://www.brewflasher.com
+
+Note! If its being flagged as malware, try the older version.
+
+The main differences:
+---------------------
+
+* Modern web based user interface for configuration when connected to WIFI
+* Efficient software, long lifespan (+45 days with 5min update frequencey)
+* Send data to multiple endpoints (http-post, http-get, influxdb v2, mqtt)
+* Instructions for service such as; Brewfather, Fermentrack, Ubidots, Home Assistant, Brewers Friend, Brewspy, Thingspeak, Blynk. 
+* SSL support in standard HTTP and MQTT connections.
+* ESP32 support with Bluetooth push
+* Customize data format to be pushed
+* Automatic temperature adjustment of gravity when enabled
+* Use the temperature sensor in gyro instead of DS18B20
+* Built in function to create gravity formulas, no need for additional software, just enter tilt/gravity. 
+* Visual graph showing how gravity formula will be interpreted
+* OTA support 
+* Built in performance measurements (used to optimise code)
+* REST API for scripting 
+
+No code has been reused from the iSpindle project. 
+
+The documenation can be found here: https://mp-se.github.io/gravitymon/index.html

+Copyright (c) 2007, Jim Studt  (original old version - many contributors since)
+
+The latest version of this library may be found at:
+  http://www.pjrc.com/teensy/td_libs_OneWire.html
+
+OneWire has been maintained by Paul Stoffregen (paul@pjrc.com) since
+January 2010.
+
+DO NOT EMAIL for technical support, especially not for ESP chips!
+All project support questions must be posted on public forums
+relevant to the board or chips used.  If using Arduino, post on
+Arduino's forum.  If using ESP, post on the ESP community forums.
+There is ABSOLUTELY NO TECH SUPPORT BY PRIVATE EMAIL!
+
+Github's issue tracker for OneWire should be used only to report
+specific bugs.  DO NOT request project support via Github.  All
+project and tech support questions must be posted on forums, not
+github issues.  If you experience a problem and you are not
+absolutely sure it's an issue with the library, ask on a forum
+first.  Only use github to report issues after experts have
+confirmed the issue is with OneWire rather than your project.
+
+Back in 2010, OneWire was in need of many bug fixes, but had
+been abandoned the original author (Jim Studt).  None of the known
+contributors were interested in maintaining OneWire.  Paul typically
+works on OneWire every 6 to 12 months.  Patches usually wait that
+long.  If anyone is interested in more actively maintaining OneWire,
+please contact Paul (this is pretty much the only reason to use
+private email about OneWire).
+
+OneWire is now very mature code.  No changes other than adding
+definitions for newer hardware support are anticipated.
+

+  Unknown chip fallback mode, Roger Clark
+  Teensy-LC compatibility, Paul Stoffregen
+  Search bug fix, Love Nystrom
+
+Version 2.2:
+  Teensy 3.0 compatibility, Paul Stoffregen, paul@pjrc.com
+  Arduino Due compatibility, http://arduino.cc/forum/index.php?topic=141030
+  Fix DS18B20 example negative temperature
+  Fix DS18B20 example's low res modes, Ken Butcher
+  Improve reset timing, Mark Tillotson
+  Add const qualifiers, Bertrik Sikken
+  Add initial value input to crc16, Bertrik Sikken

+  Improve temperature example, Paul Stoffregen
+  DS250x_PROM example, Guillermo Lovato
+  PIC32 (chipKit) compatibility, Jason Dangel, dangel.jason AT gmail.com
+  Improvements from Glenn Trewitt:
+  - crc16() now works
+  - check_crc16() does all of calculation/checking work.
+  - Added read_bytes() and write_bytes(), to reduce tedious loops.
+  - Added ds2408 example.
+  Delete very old, out-of-date readme file (info is here)
+
+Version 2.0: Modifications by Paul Stoffregen, January 2010:
+http://www.pjrc.com/teensy/td_libs_OneWire.html
+  Search fix from Robin James
+    http://www.arduino.cc/cgi-bin/yabb2/YaBB.pl?num=1238032295/27#27
+  Use direct optimized I/O in all cases
+  Disable interrupts during timing critical sections
+    (this solves many random communication errors)
+  Disable interrupts during read-modify-write I/O
+  Reduce RAM consumption by eliminating unnecessary
+    variables and trimming many to 8 bits
+  Optimize both crc8 - table version moved to flash
+
+Modified to work with larger numbers of devices - avoids loop.
+Tested in Arduino 11 alpha with 12 sensors.
+26 Sept 2008 -- Robin James
+http://www.arduino.cc/cgi-bin/yabb2/YaBB.pl?num=1238032295/27#27
+
+Updated to work with arduino-0008 and to include skip() as of
+2007/07/06. --RJL20
+
+Modified to calculate the 8-bit CRC directly, avoiding the need for
+the 256-byte lookup table to be loaded in RAM.  Tested in arduino-0010
+-- Tom Pollard, Jan 23, 2008

+Format editor
++++++++++++++
+
+To reduce the need for adding custom endpoints for various services there is an built in format editor that allows the user to customize the format being sent to the push target. 
+
+.. warning::
+
+   Since the format templates can be big this function can be quite slow on a small device such as the esp8266. 
+
+.. image:: images/format.png
+  :width: 800
+  :alt: Format editor
+
+You enter the format data in the text field and the test button will show an example on what the output would look like. If the data cannot be formatted in json it will just be displayed as a long string.
+The save button will save the current formla and reload the data from the device. 
+
+.. tip::
+
+   If you save a blank string the default template will be loaded.
+
+These are the format keys available for use in the format.

 Configuration is accessed by entering the URL for the device, this will be the mDNS name *device.local* or the IP adress. The following chapter assumes the device name is *gravmon*.
 
 The main page shows the device readings; gravity, angle, temperature and battery charge. If the checkbox is active then the device will never go into sleep mode. This is useful if 
 you are collecting angle/tilt for calibration. If this is unchecked the device will change mode as explained before.
 
+You can also view the average time a gravity measurement takes. Under optimal setting this should be around 1.5 - 2.0 seconds. If this is higher than 2 seconds this is most likley connected to slow wifi

+  but it does not validate if the remote endpoint is who it claims to be. 
 
-* **Automatic temperature adjustment of gravity reading**

 .. note::
 
-  This feature needs more testing to be validated.
+  Using SSL on a small device such as the esp8266 can be unstable since it requires a lot of RAM to work. And running out
+  of RAM will cause the device to crash. So enable SSL with caution and only when you really need it. GravityMon will try
+  to minimize the needed RAM but the remote service might not support that feature.

+* **Customize the data format beeing sent to push targets**
+
+  In order to make it easier to support more targets there is a built in format editor that can be used to 
+  customize the data that is to be sent. This way you can easily adapt the software to new targets without coding.

 Battery life
 ------------

+The long term battery test has now been completed. Using a 2200 mA battery and sending data every 5 minutes to a local server on my network. The battery lasted 47 days which is excellet battery life.

+In another test I had a device running with an sleep interval of only 30s with ok wifi connection. The device lasted 12 days which i think is excellent considering the short sleep interval.

+Hardware

+There are lots of resouces out there on how to build the hardware for an iSpindle so I will not go into details on that part. Here are two of my builds using the iSpindle PCB v4.
+
+.. image:: images/ispindel.jpg
+  :width: 500
+  :alt: Builds of iSpindel
+
+It's possible to use this PCB and mount an ESP32 on top of that. It must be an pin compatible ESP32 and the one I used was called *ESP32 d1 mini*. Since this is the same width as the PCB you need to 
+mount it really close to the PCB in order for it to fit in the PET tube/container. I also had to smooth the edge of the ESP32 in order for it to fit. 
+
+I would suggest that you try how it fits into the PET tube before soldering it to the PCB. Make sure that the battery is attached since this will be a really tight fit.
+
+You also need to desolder (remove) the RED ON LED from the ESP32 or the battery power will be reduced a lot.
+
+Final thing is to add a resistor between A0 (Analog PIN) and ground of 470k. The reason is that the esp8266 has a build in resistor which 
+the esp32 does not have. So in order to get a valid voltage (less than 3.2V) on the A0 pin this is needed. Once the modification is done you might
+need to adjust the voltage factor so the battery reading is correct.
