5.2. Sensor Attributes
sdiMsg
r/w
Send SDI command(s) in pseudo-transparent mode to an SDI
sensor. The attribute is intended to be updated through the M2M
Gateway. More than one command can be sent in one string; while
spaces between commands are optional, they improve readability.
If a delay is required between commands, it can be specified as \n,
where n specifies the delay in seconds. Example: 0M! \5 0D0! The
results returned by the sensor(s) are piped to the log.
sdiTermination
r/w
If true, it activates an 150Ω terminating resistor (valid only in RS-485
and CAN modes; default false).
swBootVersion
r
The version of the RTU’s bootloader.
swVersion
r
The version of the RTU’s firmware.
telemetry
r
A list of telemetry values reflecting various RTU conditions (power
supply, microcontroller’s temperature, RSSI, etc.).
timeZone
r/w
The ISO definition of the time zone where the RTU operates (default
UTC). The timeZoneOffset attribute is derived form this attribute.
uptime
r
Time since the last RTU’s reboot.

acquisitionMode
r/w
Defines how the sensor will be sampled (default 2). Following modes
are defined:
0 – no sampling, sensor is disabled.
1 – not used.
2 – automatic mode, defined by the sensor's aquisitionSchedule
attribute.
acquisitionSchedule
r/w
Defines the sensor sampling schedule. It uses a cron syntax, ex: */10
means that the sensor should be sampled every ten minutes starting
with minute 0. A complete cron string may specify minutes, hours,
days, months and the day of the week. The smallest unit that can be
set is therefore one minute. For additional details on configuring cron,
consult the unix man pages for crontab (5) (https://man.openbsd.org/
crontab.5).
archiveInterval
r/w
Specifies the archiving interval in minutes (default 10) on a Davis
WeatherLink logger/interface. This attribute is valid for Davis loggers
only.
davisVersion
r
Returns the software version of the Davis WeatherLink logger/
interface. This attribute is valid for Davis loggers only.
