@mz-ber the regex has to return 3 items

MZ-BER

@sdetweil Right! And I guess it is doing so? Or am I wrong?

sdetweil

@mz-ber i do not know what the module is expecting or its process

it also does a voc dashboard…
and parses that…

MZ-BER

@sdetweil Yes, I guess voc list should work. But really quick to voc dashboard

That is the list I’m getting

B-PY 186 Position             : (52.55352783203125, 13.4XXXXXXXXXX6, '2022-03-06 20:20:32+01:00', None, None)

B-PY 186 Trip meter 2         : 1 km
B-PY 186 Fuel amount          : 40 L
B-PY 186 Fuel level           : 72 %
B-PY 186 Fuel consumption     : 9.9 L/100 km

B-PY 186 Front right window   : Closed
B-PY 186 Rear left window     : Closed
B-PY 186 Rear right window    : Closed
B-PY 186 Front right tyre     : OK
B-PY 186 Front left tyre      : OK
B-PY 186 Rear right tyre      : OK
B-PY 186 Rear left tyre       : OK
B-PY 186 Washer fluid         : OK

B-PY 186 Bulbs                : OK
B-PY 186 Doors                : Closed
B-PY 186 Windows              : Closed

With the regular expression /^([^\s]+)\s([\w\s]+)\:\s(.+)$/gm it is not perfectly matching the groups:

B-PY 186 should be always in group 1. Do you have an idea to adjust the expression?

MZ-BER

I got it to work! Finally.

The whole problem was my licence plate. The regular expression wasn’t able to grab the right groups. Thank you @sdetweil for helping me to investigate.

sdetweil

@mz-ber how did u fix the regex?

i would change the 1st capture to
in the list

^([^\(]+)\s  =capture up to but not including (

in the scan = capture 1st 8 chars
how long is a license number? always 8?

^(.{8})\s

@sdetweil said in Volvo on Call:

German Number Plates can have the following format:

ABC-D 123

ABC-DE 12 

AB-C 123 

A-BC 1234

I’m using this regex to get the variations: ^([A-Z]{1,3}-[A-Z]{1,2}\s[0-9]{1,4})\s([\w\s]+)\:\s(.+)$

@mz-ber you are missing some german number plates:

AB-CD 123E electric vehicles

AB-CD 123H oldtimer, but probably not relevant because they do not have the digital information :D

The other exceptions are not relevant for private vehicles.

MZ-BER

@strawberry-3-141 True! Good catch! So I guess every variation can also have an E at the end. Do you know if there is a whitespace between the last digit and the E? If it is without a space, this will work:

^([A-Z]{1,3}-[A-Z]{1,2}\s[0-9,E]{1,5})\s([\w\s]+)\:\s(.+)$

@mz-ber officially there is no space in between the numbers and the suffix, but I work for a provider of a mobility platform and I can tell you that users frequently come up with their own formats like AB-CD123 (no space) or AB-CD 123 E (extra space).

Your regex works, but it would also cover some invalid plates like the following in case you want a challenge to improve your regex:

AB-CD 0E5E8
The number can’t start with a 0
The E can only be in the end not mixed with the numbers
