Title: Re: [weewx-user] Re: TFA Klimalogg PRO on RaspberryPi
Hi Walter,

I don't know if your approach is working. The software in the KlimaLogg PRO station is very time critical.
Perhaps you try the driver first within weewx and when it is working you can go from there.

The KlimaLogg PRO base station needs to be synchronized once with the driver.
To do this:
Press and hold the USB button for three seconds until a beep is heard, then start weewx with the kl-driver (within 5 seconds). A second beep is heard when the synchronization was succesfull.

>From now on a short press on the USB button is needed whenever the driver lost communication with the base station. The driver is telling you to do so.

There is another (much easier) way to read the values of the KlimaLogg sensors with a SDR-dongle (the base station is not needed anymore), see:
https://github.com/baycom/tfrec 
The instructions on this site to compile the tfrc program don't work anymore for Raspbian Buster. When you are interested I can send you my notes how I managed to get it work under Buster.

Success,
Luc


Luc,
I appreciate so much the profound work you have been doing over the last 5 years.
Could you please advise for my project? I am not using weewx, did not even install it. Yet I want to retrieve data from KlimaLogg-pro.

starting from:
https://github.com/matthewwall/weewx-klimalogg

My approach: call routines in your kl.py from another python program like
    from kl import *
    maxtries = 3
    klimalogg = KlimaLoggConfigurator()
    klimalogg.station = KlimaLoggDriver()
    klimalogg.check_transceiver(maxtries)
    klimalogg.pair(maxtries)
in your code KlimaLoggConfigurator and KlimaLoggDriver are subclassed from weewx classes. I removed the superclass from their definitions.
first "results":
    Checking for transceiver...
    Transceiver is present
    serial: 01012110140255
    id: 567 (0x0237)
    Pairing transceiver with console...
    Press and hold the USB button until "USB" appears (attempt 1 of 3)
    Press and hold the USB button until "USB" appears (attempt 2 of 3)
    Press and hold the USB button until "USB" appears (attempt 3 of 3)
    Transceiver not paired to console.

Would you agree, this makes sense? Anything to change up to here?
USB pairing did not work so far (pressing the button --> "USB" blinking in display, nothing else happening.


best regards
Walter

Hi Pete,

Attached the Klimalogg Pro driver compatible with python2, python3 and the weewx v.4.0 logging.

Hi everyone!

This thread has been extremely helpful. Thank you so much for all the input. Nevertheless unfortunatly I wasn't able yet to successfully get the rf communication between the raspi and the Klimalogg Pro started.

I was able to connect to the transceiver and everything went well until the log showed the error message "exception in doRF: %s" after "starting rf communication". Since I am not firm (yet) with python (I'm more one of the old php guys), I wonder if there was the possibility to have a python3 compatible version of the Klimalogg Pro driver? I did get the message to press the USB button on the console but that did not help, it kept on showing up...

Did anyone else have this problem?

Thank you again and cheers

Pete
