"""
Collect data from stl-sdr. Run rtl_433 on a thread and push the output onto
a queue.
The SDR detects many different sensors and sensor types, so this driver
includes a mechanism to filter the incoming data, and to map the filtered
data onto the weewx database schema and identify the type of data from each
sensor.
Sensors are filtered based on a tuple that identifies uniquely each sensor.
A tuple consists of the observation name, a unique identifier for the hardware,
and the packet type, separated by periods:
<observation_name>.<hardware_id>.<packet_type>
The filter and data types are specified in a sensor_map stanza in the driver
stanza. For example:
[SDR]
driver = user.sdr
[[sensor_map]]
inTemp = temperature.25A6.AcuriteTowerPacket
outTemp = temperature.24A4.AcuriteTowerPacket
rain_total = rain_total.A52B.Acurite5n1Packet
If no sensor_map is specified, no data will be collected.
The deltas stanza indicates which observations are cumulative measures and
how they should be split into delta measures.
[SDR]
...
[[deltas]]
rain = rain_total
In this case, the value for rain will be a delta calculated from sequential
rain_total observations.
To identify sensors, run the driver directly. Alternatively, use the options
log_unknown_sensors and log_unmapped_sensors to see data from the SDR that are
not yet recognized by your configuration.
[SDR]
driver = user.sdr
log_unknown_sensors = True
log_unmapped_sensors = True
The default for each of these is False.
Eventually we would prefer to have all rtl_433 output as json. Unfortunately,
many of the rtl_433 decoders do not emit this format yet (as of January 2017).
So this driver is designed to look for json first, then fall back to single-
or multi-line plain text format.
Battery Status
In the weewx database, a battery status of 1 indicates low battery. This has
origins in the original battery indicators from davis vantage stations. Some
devices report 'battery' where a value of 1 indicates that the battery is ok,
i.e., the battery is *not* low. The rtl_433 output has been changed recently
to make this less ambiguous, so many devices now report 'battery_ok' instead
of just 'battery'. There were also cases where the 'battery' value was a
string, typically just 'OK'. FWIW, user fgonza2 reports that the Acurite low
battery indicator kicks in when the voltage hits about 4V.
WARNING: Handling of units and unit systems in rtl_433 is a mess, but it is
getting better. Although there is an option to request SI units, there is no
indicate in the decoder output whether that option is respected, nor does
rtl_433 specify exactly which SI units are used for various types of measure.
There seems to be a pattern of appending a unit label to the observation name
in the JSON data, for example 'wind_speed_mph' instead of just 'wind_speed'.
