Logia 5in1 - how to get barometer reading (need something like Wunderfixer)

[Joe Williams]

Hi All,

I'm a newbie to weewx,  and I have been able to set up weewx to monitor my weather station using SDR.   All works great,  but I would like to also get the barometer reading from the console back into weewx.

My color console doesn't have a way to expose the internal sensor data (no usb/serial port),  but the console has the ability to post data directly to Weather Underground,  which includes the barometric readings (which I have been doing for the last couple of weeks).   Im thinking these are my options at this point..

1) get a sensor that works at 915.000MHz. that sends the barometric reading,  and add it to my sensor map

or

2) write a python script that logs into weather underground,  and grabs the barometric reading (that was sent by my console),  and stores it back into the SQLLite database...   Not sure if anyone has done or thought of this.

Like to do 1) if I can get a cheap sensor,  but I can do 2)

Thoughts?

Hi, 

Have done #1. Got a THGN129 from oregon scientific. it does work with SDR, but barometer is shit. measures +/-7 mbar.

Have been considering to look into another sdr compliant barometer, but did not find one (and stopped looking activley for a while now)

Regarding 2. weewx loop only support for a single device. so snooping the baro from the wmr is not an option (if I understood correctly). But there seems to be a new weewx multi that might help you on this. And there is a page on weewx github wiki that explains how to snoop on network traffic for weewx.

If you are running a RPI, you can use a BME280 Sensor.

HI,

I though about adding a BME, but I never tried because of the single loop issue. If I have 2 loops, I could hook back my WMR via USB which has a decent pressure sensor but does nto advertise it over 833MHz.

Maybe I should look into the weewx-multi.

Thanks for the thoughts Storm and sbarthes!

Im running an older RPI 3.    I really like the idea using the BME280 sensor.   I can pick one of those up on Amazon for $15 CDN. :)

I did find this weewx extension for the BME280 sensor… -> https://gitlab.com/wjcarpenter/bme280wx

"bme280wx is an extension to weewx weather station software. It gives the ability to supplement existing station readings with temperature, pressure, and humidity readings from a Bosch BME280 integrated environmental sensor”

Im guessing that the BME280 will happly co-exist with the SDR that I’m using on the RPI.       Think Im going to try this out.

Cheers,

-Joe

Yes it will.  Been running the bme280wx extension and weewx-rtldavis (SDR) without out any issues.

Hi Joe,

Just checking ... I'm assuming you have the WiFi version of the Logia 5in 1 rather than the PC version:

https://logiaweatherstations.com/collections/all/products/5-in-1-wireless-weather-station-with-pc-data-sync

If you have the PC version you can use the WS6in1 driver, which will get you the Barometer and indoor temperature/humidity 

Regards

Bob

Hi Bob,  that’s correct,  I am using the wifi version.
