 # Gravity Monitor for Beer Brewing

-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.
+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. 
+
+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:
 ---------------------

-* Operates in two modes gravity monitoring and configuration mode (simplify calibration)
-* Modern web based UI for configuration (in config mode)
-* REST API
-* Send data to multiple endpoints when pushing data (2xhttp, brewfather, influxdb v2, mqtt supported)
-* Automatic temperature adjustment of gravity reading
-* OTA support from local webserver
-* Built in function to create gravity formulas, no need for additional software, just enter tilt/gravity. 
-* Visual graph showing how formula will be interpreted
-* Using the temperature sensor in gyro instead of DS18B20 (faster)
-* Built in performance measurements (used to optimise code)
+* 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.

 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 
+connection. It will show 0 if data has not been collected yet.

-   This is unique identifier for the device (ESP8266 id), this is required when using the API as an API Key to safeguard 
-   against faulty requests. This is the ESP8266 chip ID, so it should be unique.

+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.

 Releases 
 ########

+v1.0.0
+------
+* Upgraded to bootstrap v5.1 for web pages.
+* Added tooltips to all fields in user interface
+* Removed brewfather option (can use standard HTTP options), the old apporach can still be used via changing format template.
+* Added 5 more points for formula creation, so a total of 10 angles/gravity values can be stored.
+* Added function on format page so that it's easy to copy a format template from the docs (simplify service integration).
+* Added https support for Influxdb
+* Added possibility to have variable push intervals for different endpoints so that different frequency can be used, for example; 5min mqtt, 15min brewfather. 
+* Added advanced settings to configuration for adjusting some internal values (gyro reads, accepted formula deviation, timeouts, moving detection etc).
+* Added additional http error codes to troubleshooting documentation
+* Installation instructions updated on how to find the device after wifi has been configured. 
+* Documentation on brewfather has been updated to adress SG/Plato conversion
+* BUG: Fixed issue in formula calculation in case there were a gap in the data series
+* BUG: Field name for wifi strenght changed from "rssi" to "RSSI"
+
+* TODO: Fix documentation for advanced settings.
+
+v0.9.0
+------
+* Added one http push target that uses HTTP GET. This can be used with ubidots or blynk api's. 
+* Added function to test push targets from configuration page. It will send data and show the return code as a first step. 
+* Added documetation on how to integrate with Blynk.io using http get.
+* Config page now shows the estimated runtime for the device (based on a full battery and previous average runtime)
+* Experimental release of firmware using an esp32 instead of esp8266
+* Merged index and device pages into one so that all the needed information is available on the index page.
+* Removed api for device (/api/device), it's now merged into the /api/status api.
+* Test function in format editor now uses real data and not fake. 
+* Split push configuration into two sections to make it fit better on smaller devices
+* Updated WifiManager and DoubleReset libraries
+* Updated esp32 target with littlefs support
+* Updated esp32 target with BLE send support (it will simulate a tilt)
+* Mounted esp32 d1 mini mounted to a iSpindle PCB 4.0 (CherryPhilip) which worked fine.
+* Documented hardware changes on esp32
+* Default mDNS name is now shown on WIFI setup page.
+* Added option to manually update/downgrade firmware under hardware settings. 
+* BUG: Corrected PIN for voltage read on ESP32
+* BUG: If using plato and not gravity formula was defined the value was set to null.
+* BUG: Temp format name was incorrect in iSpindle format causing receiver to incorrectly read temperature.
+* BUG: Temperature sensor adjusmemnt value was not handled properly when using Farenheight.
+* BUG: If the ID was to low the device id could end up with a leading space causing errors in data post. Added leading zero to ID.
+* BUG: Entering wifi setup and a timeout occured the wifi settings could be deleted.

 Brewfather is an all in one service that allows you to manage you recepies and brews. 

-Just enter the http adress found on brewfather, not other settings are needed. The endpoint has the following format:
+**Option 1** - iSpindle Endpoint
+
+This opion makes use of the standard http (1 or 2) endpoints in the push section. If you are using SG then the device name needs to end with [SG] or brewfather will assume 
+that the data is in plato. You can also modify the format template using the following options:
+
+Update the following part `"gravity": ${gravity-plato},` or `"name" : "${mdns}[SG]",``
+
+This makes use of the standard format template, no changes needed.

 .. code-block::

-   http://log.brewfather.net/http://log.brewfather.net/stream?id=<yourid>
+   http://log.brewfather.net/ispindel?id=<yourid>


-The URL is found under settings.
+Documentation on this can be found under `Brewfather iSpindle Endpoint <https://docs.brewfather.app/integrations/ispindel>`_
+
+
+**Option 2** - Custom Stream
+
+This option makes use of the http push endpoint with a custom format template. Just enter the http stream adress found 
+on brewfather, not other settings are needed. The stream endpoint URL has the following format:
+
+.. code-block::
+
+   http://log.brewfather.net/stream?id=<yourid>
+
+Documentation on this can be found under `Brewfather Custom Endpoint <https://docs.brewfather.app/integrations/custom-stream>`_

+Blynk.io
++++++++
+
+Blynk is an IoT service which can be updated via http get. It also has an mobile device that can be used to show the data.
+
+In order to use this platform you need to create a device which can be used to receive the data. Each device will have a 
+unique token that is used to identify it. You need to use the HTTP GET option (http-3) on the device for this to work. Enter the 
+following URL in the UI. This will allow us to update several data points at once. I usually enter the token in the ``token2`` field 
+so the format template does not contain any sensitive data and it's easier to switch to another device. 
+
+.. code-block::
+
+   http://blynk.cloud/external/api/batch/update
+
+
+In the format editor you can enter this template which will send 3 values to blynk. You can add as many as you want but make sure 
+these are configured on the device with the correct validation option such as data type and range. The value should be on one line 
+starting with a ``?``. This string will be added to the URL above when doing the post. You can add more values if you want.
