read-only,
floating point
Temperature read every 30 seconds. Resolution .5C (uses an
on-board DS18B20). Temperature is only present in the
EE-series devices.
read-write,
floating point
Offset stored on device to apply to temperature
readings.
read-only
floating point
UV Index (ultraviolet index) in the range 0.0 to 16.0
resolution .1
Only the UVI version of the EE device has a UVI sensor. Readings made every .5 seconds.
read-write,
floating point
Signed offset to apply to the UVI measurement. Stored
on-device non-volatile.
read-write,
yes-no
Flag to apply compensation for the protective case. Stored
on-device non-volatile.
read-only, yes-no Flag the the EE device type matches the known UVI type.
read-only
integer
Up to 4 sensors reading moisture can be attached.
OWFS addresses the sensors as 0 through 3 while the
datasheet uses 1-4. Two types of external sensors are
supported (and the data range):
Watermark Soil Moisture Sensor
0-199
Leaf Wetness Sensor
0-99
read-write
yes_no
Set or get the type of sensor attached to each channel. Note
that OWFS addresses the sensors as 0 through 3 while
the datasheet uses 1-4. Two types of external sensors are
supported:
Watermark Soil Moisture
Sensor
Leaf Wetness
Sensor
Note that is_leaf and is_moisture are complementary and clearing one sets the other.
read-write
unsigned integer
Set or get the upper and lower range for the raw data for
leaf wetness scaling. See the datasheet for details.
read-only
unsigned integer
Read the raw leaf wetness values for setting scaling. See
the datasheet for details. Note that OWFS addresses
the sensors as 0 through 3 while the datasheet uses 1-4.
4-channel hub. Individual branches can be switched on and off.
read-write,
yes-no
The HobbyBoards hub has four 1-wire bus lines. Each branch
is electricaly isolated from reflections and shorts, and can
be optionally excluded from the 1-wire network.
You can turn each branch on or off by writing 0 (off) or 1 (on) to the corresponding property. Note that OWFS indexes the branches 0 to 3 while the datasheet uses 1 to 4.
The easiest way to turn all the branches on is to write 15 (0x0F) to hub/branch.BYTE
read-only,
yes-no
Is the corresponding branch in "short" condition?
(Electrically shorted out).
read-only,
ascii
Firmware version for the EE/EF device. Reported in nn.nn
format where nn is major/minor decimal value.
Note: This format was changed as of version owfs-2.9p6 at the request of the HobbyBoards. Formerly reported in HH.HH format where HH is a hex digit (0-9A-F).
read-only,

The EEEF (3) are a reference platform of microprocessor based 1-wire slaves. In general they require external power, and have an on-board index for the specific capabilities. They are designed by Eric Vickery at HobbyBoards.com
The EE class device uses family code EE and has an included temperature sensor. The EF devices have no temperature sensor,
The UVI sensor is an implementation of the EE class device with Ultra Violet Index sensing. All it’s specific properties are in the UVI/ directory.
