weewx-skyvex

A WeeWX extension that uploads your weather data to Skyvex.

Skyvex speaks the Weather Underground upload protocol. This extension uses the same uploader class as WeeWX's built-in Wunderground service (weewx.restx.AmbientThread), but with a section of its own, [[Skyvex]]. That way you can keep posting to Weather Underground and post to Skyvex at the same time.

Each archive record is sent once, in US units, the same fields WeeWX sends to Weather Underground (temperature, humidity, dew point, pressure, wind, rain, solar radiation, UV, soil and leaf sensors, PM2.5/PM10). Indoor values are sent only with post_indoor_observations = true.

Soil moisture and leaf wetness are sent on the Davis scale: soilmoisture in centibar (0 = wet, 200 = dry), leafwetness as an index from 0 to 15. Skyvex does not read soilmoisture as a percentage; in the Skyvex settings, under Sensors, create a custom field mapping for soilmoisture with the unit cb.

Requirements

• WeeWX 4 or 5 running under Python 3 (tested against WeeWX 4.10.2 and 5.0 to 5.5.2)
• A Skyvex account. Your Station ID and station password are shown in the Skyvex settings on your station card. The station password is not your login password.

Installation

WeeWX 5:

weectl extension install https://github.com/MichaelStrommer-dreiS/weewx-skyvex/archive/refs/heads/main.zip

WeeWX 4 (wee_extension does not accept URLs, so download first):

wget -O weewx-skyvex.zip https://github.com/MichaelStrommer-dreiS/weewx-skyvex/archive/refs/heads/main.zip
sudo wee_extension --install weewx-skyvex.zip

Configuration

The installer adds a disabled [[Skyvex]] section to [StdRESTful] in weewx.conf. Fill in your values and enable it:

[StdRESTful]
    [[Skyvex]]
        enable = true
        station = STATION-ID
        password = PASSWORD

Optional settings:

Option	Default	Meaning
post_indoor_observations	false	Also send indoor temperature and humidity
server_url	https://api.skyvex.org/weatherstation/updateweatherstation.php	Upload endpoint
log_success / log_failure	from weewx.conf	Log every upload

Rapidfire (loop packet) uploads are not supported; rapidfire, archive_post and rtfreq are ignored.

Restart and check

sudo systemctl restart weewx
journalctl -u weewx -f

After the next archive interval (usually five minutes) the log shows:

Skyvex: Published record 2026-09-30 14:05:00 CEST (1790770700)

Skyvex: Failed to publish record ... HTTP Error 401 means the Station ID or the station password is wrong.

Alternative without this extension

If you do not post to Weather Underground, you do not need this extension: WeeWX's built-in Wunderground uploader can be pointed at Skyvex with the option server_url. Details and ready-to-copy snippets: https://skyvex.org/setup-guide#weewx

Uninstall

weectl extension uninstall skyvex        # WeeWX 5
sudo wee_extension --uninstall skyvex    # WeeWX 4
