The main differences
|
|
--------------------
|
|
|
|
* **Operates in two modes `gravity monitoring` and `configuration mode`**
|
|
|
|
In gravity monitoring mode it behaves just like the iSpindle, it wakes up at regular intervals, measure angle/tile, temperature, calculates gravity and pushes the data to defined endpoints.
|
|
|
|
In configuration mode the device is always active and the webserver is active. Here you can view the angle/tilt values, change configuration options and more. When in this mode you can also interact with the device
|
|
via an REST API so data can be pushed to the device via scripts (see API section for more information)-
|
|
|
|
*See the configuration section for more information on how to trigger the configuration mode.*
|
|
|
|
* **Can send data to multiple endpoints at once**
|
|
|
|
The orignial iSpindle can only have one destination, this sofware will push data to all defined endpoints so in theory you can use them all. However this will consume a lot of battery power so use only as many as needed.
|
|
|
|
Currently the device supports the following endpoints: http (2 differnt), influxdb2 and Brewfather
|
|
|
|
If you want additional targets please raise a feature request in the github repo.
|
|
|
|
* **Build in function to create gravity formulas, so no need for using other tools for this part**
|
|
|
|
Another big difference is that this software can create the gravity formula in the device, just enter the angle/gravity data that you have collected. You will also see a graph simulating how the formula would work.
|
|
|
|
* **Automatic temperature adjustment of gravity reading**
|
|
|
|
If you want to correct gravity based on beer temperature you can do this in the formula but here is a nice feature that can correct the gravity as a second step making this independant of the formula.
|
|
|
|
.. note::
|
|
|
|
This feature needs more testing to be validated.
|
|
|
|
* **OTA support from local webserver**
|
|
|
|
When starting up in configuration mode the device will check for a software update from a local webserver.
|
|
|
|
* **DS18B20 temperature adjustments**
|
|
|
|
You can adjust the temperature reading of the temperature sensor.
|
|
|
|
* **Gyro Movement**
|
|
|
|
The software will detect if the gyro is moving and if this is the case it will go back to sleep for 60seconds. This way we should avoid faulty measurements.
|
|
|
|
Other features
|
|
--------------
|
|
|
|
* Support for Celcius and Farenheigt as temperature formats.
|
|
|
|
* Support SG (Plato is not yet supported)
|
|
|
|
* Gyro data is read 50 times to ensure good accuracy
|
|
|
|
Experimental features
|
|
---------------------
|
|
|
|
* Use the temperature sensor in the gyro instead of DS18B20
|
|
|
|
This works fine when the device has time to cool down between measurements and it saves a few milliseconds (reduced battery consumption). My testing shows that this is quite accurate.
|
|
|
|
.. note::
|
|
|
|
This is not enabled by default.
|
|
|
|
* Performance measurements
|
|
|
|
I've also create a small library to measure execution code in some areas of the code that i know is time consuming. This way I can find a good balance between performace and quality.
