Trouble installing WeeWX-MQTTSubscribe

[Frank Gruhlke Gg]

Hello all..   hopefully someone can help me!

I have a fresh raspbean install on a pi-4 and want to install the MQTT driver found here:

https://github.com/bellrichm/WeeWX-MQTTSubscribe

So far managed to install the Paho MQTT Python Client but then started to run into issues.

First,  DOWNLOAD_DIR = /tmp   gave me a "bad command error so I adjusted and ran:

/tmp $ wget https://github.com/bellrichm/WeeWX- MQTTSubscribe/archive/refs/tags/v2.3.1.tar.gz

and managed to get "v2.3.1.tar.gz into the /tmp directory

now it seems no matter what I try I cant install from here..

frank@pi4:/tmp $ BIN_DIR/wee_extension --install=v2.3.1.tar.gz
bash: BIN_DIR/wee_extension: No such file or directory

also tried 

frank@pi4:/tmp $ BIN_DIR/wee_extension --install v2.3.1.tar.gz
bash: BIN_DIR/wee_extension: No such file or directory

I am sure its something minor but I have no hair left to pull!

You caught me in the middle of a major documentation update.

For weewx v5 use, http://www.weewx.com/docs/5.0/utilities/weectl-extension/ and http://www.weewx.com/docs/5.0/utilities/weectl-station/

And v4, http://www.weewx.com/docs/4.10/utilities.htm#wee_extension_utility and http://www.weewx.com/docs/4.10/utilities.htm#Action_--reconfigure

Then manually update weewx.conf using https://github.com/bellrichm/WeeWX-MQTTSubscribe/wiki/Common-Options as a reference

Drop the BIN_DIR

wee_extension --install=v2.3.1.tar.gz

Assuming you are /tmp

Thanks for helping me out...  here is what got..

frank@pi4:/tmp $ wee_extension --install=v2.3.1.tar.gz
bash: wee_extension: command not found

[Rich Bell]

Just double checking, you installed WeeWX 4.x?

What method, package or setup?

It’s a bit of a matrix of what to do depending on WeeWX version and install method. I am hoping to simplify my instructions, but the docs are partially done. Sorry about that. We’ll get you up and running.

You didn't say which version of weewx but you probably installed v5.

See if 'weectl extension install' works (v5 syntax) rather than 'wee_extension --install' (v4 syntax).

[Frank Gruhlke Gg]

That got me much closer...    but (PermissionError: [Errno 13] Permission denied: '/etc/weewx/bin/user/MQTTSubscribe.py')

And sorry, yes using WeeWx 5

[Frank Gruhlke Gg]

This worked!   Vince and Rich, thank you so much!!

sudo weectl extension install https://github.com/bellrichm/WeeWX-MQTTSubscribe/archive/refs/tags/v2.3.1.tar.gz

[Frank Gruhlke Gg]

I am still trying to get everything installed correctly...

I can install weewx 5,  no problem    (sudo apt install weewx)

I can install Paho-Mqtt, no problem   (pip install paho-mqtt)

I am using this to install  WeewxMQTTSubcribe (sudo weectl extension install https://github.com/bellrichm/WeeWX-MQTTSubscribe/archive/refs/tags/v2.3.1.tar.gz)

When use" "wectl station reconfigure", it indicates I may have path issues?

Installed drivers include:
  0) ?               (user.MQTTSubscribe)      No module named 'paho'
  1) AcuRite         (weewx.drivers.acurite)
  2) CC3000          (weewx.drivers.cc3000)
  3) FineOffsetUSB   (weewx.drivers.fousb)
  4) Simulator       (weewx.drivers.simulator)
  5) TE923           (weewx.drivers.te923)

Use the packaged version of paho-mqtt.....

$ sudo apt-get install python3-paho-mqtt

[Frank Gruhlke Gg]

That worked, thank you vince!

Quick question, I use a ESP32 with an attached BME280 programed to gather my data and then use "weewxMQTTSubcribe" to feed Weewx.

The outdoor station sends the temp in "C" and the BME280 sends the pressure in "Pa"

Where and how in my chain does it makes the most sense to convert the temperature to "F" and the pressure to "inHg" ?

[bell...@gmail.com]

You have a couple of options. If all (or the majority) of your data coming in is metric, you can use; https://github.com/bellrichm/WeeWX-MQTTSubscribe/wiki/Common-Options#unit_system
Or you can set it at the field level via, https://github.com/bellrichm/WeeWX-MQTTSubscribe/wiki/Additional-Options#units

[Frank Gruhlke]

Hey Rich, thanks again... I managed to get my out-door temp to read F with this in my weewx.conf:

[[[[temperature_C]]]]
            ignore = false
            name = outTemp
            units = degree_C

I have tried every "units" option for Weewx  Barometer unit ( inHg, mbar, hPa and kpa)

for the "pa" field in my mqtt topic.

 [[[pa]]]]

          ignore = false # opt back in for this field
           name = barometer
           units = hPa

I just get  N/A (N/A) for the Barometer Reading in my reports.

I don't see any errors restarting weewx.

Here is what I am subscribed to in the driver.

"pa" is the pressure reading I am trying to bring into Weewx

{

"tempc": 20.59,

"tempf": 69.062,

"hum": 38.88184,

"pa": 98790.06,

"altim": 213.1839,

"altift": 699.4224

}

Any Ideas?

[Frank Gruhlke]

On a weewx re-boot this morning I spotted this warning:

WARNING weewx.qc: 2024-02-01 19:29:32 CST (1706837372) LOOP value 'barometer' 2924.9393558775 outside limits (26.0, 32.5)

Seems the driver is now converting the BME280 T reading of 98790.06  to  2924.9393558775.  Point of reference (30.00 in) is about right for my location at this time.

Is there a way for the driver to also reformat the 2924.9393558775 to something more like 29.24 ?

[bell...@gmail.com]

So it looks like your pressure is off by a factor of 100. I would think either of these would work (untested).
http://www.weewx.com/docs/5.0/reference/weewx-options/stdcalibrate/?h=stdco
[StdCalibrate]
[[Corrections]]
barometer = barometer / 100

https://github.com/bellrichm/WeeWX-MQTTSubscribe/wiki/Additional-Options#conversion_func

[[[pa]]]]
ignore = false # opt back in for this field
name = barometer
units = hPa

conversion_func = lambda x : x / 100

I can see pros and cons of either.

[Frank Gruhlke]

Tried option #2 and weewx is now reporting the barometer in inHg!  Truely appreciate your willingness to help!

Thank you, thank you, thank you!

[bell...@gmail.com]

That’s great! Thanks for letting us know.
