Parser for TS-FT002 433 mhz water level gauge for WeeWx #70

Closed splobsterman closed 4 years ago

splobsterman commented 4 years ago

This gadget uses ultrasound to provide liquid level data but needs a parser to use with WeeWx.

rtl_433 sees it using: rtl_433 -R 125

Any pointers about how to do this? I took a look at sdr.py and it's well above my pay grade.

rtl_433 output:

time : 2019-12-22 16:57:58 model : TS-FT002 Id : 127 Depth : 186 Temperature: 20.9 C Transmit Interval: 180 Battery Flag?: 8 MIC : CHECKSUM

matthewwall commented 4 years ago

please run rtl_433 but with the JSON output. something like this:

rtl_433 -M utc -R 125 -F json

then post some of the resulting output. 5 or 10 samples should be enough.

Matthew,

please try weewx-sdr as of commit fe08ccc

Matthew,

The parser works but with an odd result:

Running sudo PYTHONPATH=bin python bin/user/sdr.py --cmd="rtl_433 -M utc -F json -G”:

out:[u'{"time" : "2019-12-23 17:25:58", "model" : "TS-FT002", "id" : 127, "depth_cm" : 62, "temperature_C" : 26.400, "transmit_s" : 180, "flags" : 8, "mic" : "CHECKSUM"}\n', u'{"time" : "2019-12-23 17:25:58", "model" : "TS-FT002", "id" : 127, "depth_cm" : 62, "temperature_C" : 26.400, "transmit_s" : 180, "flags" : 8, "mic" : "CHECKSUM"}\n'] parsed: {'transmit.0000.TSFT002Packet': 180.0, 'dateTime': 1577121958, 'flags.0000.TSFT002Packet': 180, 'temperature.0000.TSFT002Packet': 26.4, 'depth.0000.TSFT002Packet': 62.0, 'usUnits': 16}

So I added 'depth.0000.TSFT002Packet’ to my SDR sensor map:

[SDR]

This section is for the software-defined radio driver.

# The driver to use
driver = user.sdr
log_unknown_sensors = True
log_unmapped_sensors = True
[[sensor_map]]
    extraTemp2 = temperature.1:215.AmbientF007THPacket          # pool temperature
    extraTemp3 = temperature.001A.AcuriteLightningPacket            # temp at lightning detector
    soilTemp1 = strikes_total.001A.AcuriteLightningPacket           # total strikes
    soilTemp2 = distance.001A.AcuriteLightningPacket                # strike distance
    leafTemp1 = depth.0000.TSFT002Packet                    # depth in cm tank level

and when I run sir.conf, it transmits this to the sdr.sdb:

LOOP: 2019-12-23 13:49:58 EST (1577126998) dateTime: 1577126998, leafTemp1: 147.2, maxSolarRad: 574.533540052, rainRate: 0, usUnits: 1

I am unsure how the 62 CM (I’ve checked it with my metric tape) gets transformed to 147.2. Have I mis-configured something?

Regards, and best wishes for the holidays.

you need to tell weewx what units to use. in its default configuration, leaftTemp1 is temperature, not length.

put this into the file user/extensions.py then restart weewx. also, be sure to clear the old data.

import weewx.units
weewx.units.USUnits['group_range'] = 'inch'
weewx.units.MetricUnits['group_range'] = 'cm'
weewx.units.MetricWXUnits['group_range'] = 'cm'
weewx.units.obs_group_dict['leafTemp1'] = 'group_range’

Thank you Matthew, most helpful.
