hoplite's Issues

Backend rework for 2.0

Introduce a tap object
- Taps are where the beer comes out
- Single object associated with kegs, specific sensor channels, in both real life and Hoplite
- tap object will have references to a specific sensor instance and a single channel on said instance
- also a reference to the currently loaded keg object for that tap
Create a generic sensor object
- Subclass that object for hx711_sensor
- Allows common logic for different sensor types in the future
Move all weight->volume logic inside keg objects
- update() function for getting new weight data, converting to available volume
- available_volume() function for getting that converted data out
- data stored internally as metric volume, do all weight->volume conversion during update()
Rework UI process
- Create sensor, define type, channels, etc.
- Create tap, associate with sensor
- Create keg with sizes, beer names, etc.
- Associate keg with specific tap

Setting a keg tare weight or volume to 0 causes a division by zero error

This happens in both web and main processes.

Automatically build RasPi images

Figure out a way to use pipelines to build RasPi images for releases and on every commit. There should be an existing method to build a minimal Raspbian/Ubuntu/LibreELEC image via GitHub, then cram in Hoplite.

SNMP, LLDP, MDNS support

Adding additional protocols and things could make the experience a lot more pleasant and extensible.

Move file handling to pkgutil

Also make a module for static included files, or add that to the config module.

Add an About page on the web GUI

Would be neat to have a help/about page on the Web GUI that links to the wiki, and has the current version of Hoplite, the hardware it's running on, and maybe an update checker.

Redo tare/calibration procedure to use web UI

Doing this via command line sucks and is a hack from before the web UI existed.

Applying settings in web interface causes duplicates of weight data

Ended up with this mess during troubleshooting of #5 - every time I attempt to save data back to the shmem, the weight data is duplicated.

pi@hoplite:~ $ sudo cat /dev/shm/hoplite

    "co2": [
      60

Expand web UI configuration options

Need to be able to perform all tasks from the Web UI:

Create/delete sensor listings
Add/remove kegs from sensor listings
Change system-wide settings (preferred units, etc.)

The shmem stuff is a mess anyway, may fix this by moving the web interface to using the API.

Python 3 support/cutover

In theory Hoplite should still run with Python3 from the work done for v1.0.6 but I haven't tested it yet.

Since Python 2 is EOL I should make Hoplite Python3 only.
