After a couple of years thinking that a new weather station was required and
having previously looked at Ecowitt models in Dec 2023 and putting the idea on
hold, further issues with intermittent data in Oct/Nov 2024 from the
existing weather station's Wind Sensor even after installing new batteries it
was decided today (2024-11-02) to purchase an Ecowitt Wittboy Station with
Gateway (see description of
Ecowitt Wittboy with GW2000 Gateway)
2024-11-12
- Ecowitt Wittboy unpacked
- EcoWitt Wittboy & GW2000 Gateway setup
in a temporary configuration indoors
- Connected GW2000 Gateway to Home
Lan via the short Ethernet Cable provided.
The station
gateway appears in router's network list as 'GW2000X', with IP:
192.168.1.53
- CumulusMX.exe opened (opens cmd window)
-
http://localhost:8998 used to bring up CumuluMX program
-
Configuration WIZARD used to set up connection with Ecowitt weather station,
using station's IP Address
with data saved locally to
"C:\Data\AllSky Imaging\Weather Station\" and with the following data units
- Closed and reopened CumulusMX
"windunit": "mph"
"pressunit":
"mb"
"rainunit": "mm"
- Noted that CumulusMX
immediately began saving live gauge data to the file "realtimegauges.txt"
- After a while the it began saving data to a number of JSON files:
Contents of data folder
2024-11-20
- WN31 (additional temperture/humidity sensor) arrived today
- Set
channel to Ch1 & units to Celsius (these were default settings anyway)
-
Installed batteries and the placed the sensor near to GW2000 Gateway to
allow it to automatically pair
- Replaced '-99' placeholders in
CumulusMX's realtimegaugesT.txt template with <#ExtraTemp1>,
<#ExtraHum1> & <#ExtraDP1>
- Confirmed that CumulusMX is accessing and
outputting the new sensor values correctly to the realtimeguages.txt file.
- Updated AstroWeather to read new sensor data into
Ch1Temperature,Ch1Humidity & Ch1DewPoint fields in WeatherData records
-
Updated AstroWeather to display new sensor (Ch1) values on Data Tab
-
Changed data recording frequency to the Monthly Data Files to 1 minute.
- Mounting Pole arrived today
- Examined how the mounting pole fits
to Ecowitt Wittboy and to its mounting bracket.
- 20m long 12v Power Cable and A/C Adapter arrived today
- Examined
how cable will fit to Ecowitt Wittboy and to A/C Adapter
- Built and fitted Bird Spike Circle to Ecowitt Wittboy.

After a couple of years thinking
that a new weather station was required and having previously looked at
Ecowitt models in Dec 2023 and putting the idea on hold for a year,
further issues with intermittent data from the exitsing Weather Station's
Wind Sensor in Oct/Nov 2024(even after installing new batteries)
it was decided today (2024-11-02) to purchase an Ecowitt GW2001 Wittboy with
GW2000 Gateway from Amazon (
https://www.amazon.co.uk/dp/B0BBRC5W6M/?th=1 ).

Cumulus is free software for
retrieving, storing and displaying data from an electronic Automatic Weather
Station (AWS).
See
https://www.cumuluswiki.org/a/About_Cumulus for more information about
Cumulus.
Cumulus will be reviewed and examined as a potential means of
transfer weather data between a newly ordered EcoWitt weather station and my
AstroWeather program running on the observatory's AllSky/Weather Computer.
This is part of a project to eventually replace the Observatory's existing
Oregon Scientific Weather Station & VWS Software.
Cumulus MX
Cumulus MX v4.2.1 build 4043, 19-October-2024 was downloaded today
(2024-11-02) from
https://cumuluswiki.org/a/Software
Source Code (on github) :
https://github.com/cumulusmx/CumulusMX
An installation guide is
available at
https://cumulus.hosiene.co.uk/viewtopic.php?t=22051
This
version of Cumulus MX (CMX) moves away from .Net Framework 4.8 to .NET 8.
and requires .NET8 to be present on the computer.

Design Change for Observatory's new Ecowitt Weather Station
CumulusMX's 'realtimegauges' template will have the following construction
comprising 20 fields in a comma separated single line record
<#timeUTC format=yyyy-MM-dd>T<#timeUTC
format=HH:mm:ss>Z,V1,<#temp>,<#hum>,<#dew>,-99,-99,-99,
<#intemp>,<#inhum>,<#press>,<#wlatest>,<#wspeed>,<#wgust>,<#bearing>,<#avgbearing>,<#rrate>,<#rfall>,<#Light>,<#UV>
which generates a record like the following :
2024-11-16T19:14:51Z,V1,19.2,49,8.2,-99,-99,-99,21.1,45,1006.9,2,1,3,107,109,0.0,0.0,0.0,0.0

After installation of new equipment in Nov 2024 Ecowitt GW2000 Hub and
Tapo C325WD Camara the 5 port Ethernet Hub will be fully utilised and any
additional ethernet devices will require a new Hub with additional ports.
The existing Ethernet Switch is a 10/100 model, and after installation
of Cat6 cable direct to the router, there may now be a benefit in using a
100/1000 Switch model. Previously with the slower
Ethernet-Over-Powerline connection there was no benefit in using a 100/1000
Switch.

Following diagram compares the use & configuration of the Observatory's
Ethernet Switch as it has been since the Clair Dome Observatory was kitted out
in 2018 (and still was as at 2024-10-01), with the proposed use & configuration
moving forward.
