Trying to gee AS3935 to work with weewx 4.5.1

[philip....@gmail.com]

Have a new install of weewx installed (4.5.1)  on a Raspberry Pi and using the Simulator driver loaded  the zip file from as3935 · weewx/weewx Wiki · GitHub with no problems

Stopped and Started weewx but will not start now.

In weewx.conf under

[Engine]

[[Services]]

process_services =  , user.as3935.AS3935  (This was added)

If I remove  user.as3935.AS3935 from process_services weewx will start OK but the AS3935 does not add anything to the database.

The AS3935.py is version 6

Just wondered what I have missed.

Thanks for any help

See https://github.com/weewx/weewx/wiki/faq-python-error

You have a variety of options:

• find a later version of the driver/extension that supports python3
• patch your copy to be python3 compliant using 2to3
• use python2 for your installation

In your particular case it looks like the second option is pretty trivial.

Change the offending line to be

     except Exception as e:

And see if that works ok...

[philip....@gmail.com]

Thanks Vince

Changed Line 233 to except Exception as e:

It then moved to Line 73 === no such module but sudo pip3 install RPi_AS3935 seems to have cured that (Installed ver 0.2.0 OK)

Now it stuck on Line 153 'object not callable. (address=addr, bus=bus)  

In weewx.conf I have

[AS3935]

address = 3

bus = 1

Pin 17

calibration = 6

Think I will try weewx 3.9.2, as I think that was the last python2 version , just to see if my lighnting sensor does work.

> Think I will try weewx 3.9.2, as I think that was the last python2 version

All WeeWX releases to date have been python 2 compatible, including any 4.x releases. Python 4.0.0 and later are also python 3 compatible. It all comes down to what dependencies you have installed and what version of python WeeWX is run under.

Phil:

In looking at your weewx.conf, you may want to switch the process service to be before the comma. I think the error is because you are passing [None] as the first object in the process_services dictionary.

[Engine]

[[Services]]

process_services =  user.as3935.AS3935, 

After that, it maybe prudent to go through and covert the AS3935 code to python3 syntax.

Thanks Doug but it didnt make any difference

As Im trying to use a DFRobot AS3935 I started again but this time on Python2

The i2cdetect -y 1 shows 03 show it appears the Raspberry Pi can see the AS3935

Using the simulator driver weewx now starts

Im using the zip file from as3935 · weewx/weewx Wiki · GitHub

Have loaded sudo pip install RPi_AS3935 and sudo pip install GPIO

In each 300second cycle I just get the last 5 lines from above with nothing regarding the lightning detector

The database has the lightning fields in but always shows NULL

There isn't any lightning about at present but just wondered if thats correct 

Using weewxd the loop string I don't see anything to do with lightning .

Thanks for any help Phil

In the as3935.py

[philip....@gmail.com]

In the as3935.py I noticed for LOOP working I have to put that in the weewx.conf file which then showed lightning_strikes = 0

When checking the weewx.sdb it didnt have a lightning_strikes field its called lightning_strikes_count

When I added lighnting_strikes it now has a zero (0) in. 

So has the field names changed ??

The test will be when I get any lightning I shall keep you posted.

[philip....@gmail.com]

Lightning all round today but the only log entries were when the lightning was over head 7 in total

as3935: strike at 1.0 km

Calibration = 6 , changed to 2 didn't seem to make any difference

Storms now gone and still not sure if the dfrobot works that well

[ian.r...@gmail.com]

I think I have found the remaining Python 2 issue - 2to3 didnt find it when I tried

In as3935.py on line 73 change from:

from RPi_AS3935 import RPi_AS3935

to:

from RPi_AS3935.RPi_AS3935 import RPi_AS3935

Seems to be related to the situation discussed here

https://stackoverflow.com/questions/4534438/typeerror-module-object-is-not-callable

[philip....@gmail.com]

Im using python2 so as to get a lightning detector to work to that

Just had several lightning strikes overhead but it only recorded 1 strike 10km away and nothing else

Can anybody recommend a lightning detector that does work connected to a raspberry pi via weewx

The mod 1016 from EMBEDDED ADVENTURES has been mentioned but they dont seem to be in business anymore  

Thanks

Phil

[philip....@gmail.com]

Is the Calibration figure in weewx.conf the same as the tuning capacitance of the chip on the lightning detector

Why I ask is the dfrobot = 8 - 120 pf and has to be in multiple of 8's

They suggest 96 to start with but the Calibration figure in weewx.conf will only except 0-15

Or does that relate to some other figure

Thanks in anticipation

Phil
