[Honeywell FX020] Failed to Communicate about sia HOT 13 OPEN

Hi @Alexwijn I don't know what is going on there, what you could try (if you know a bit of python) is to run the underlying package (https://github.com/eavanvalkenburg/pysiaalarm) code and see what kind of messages are being sent by the alarm, before all the parsing happens, the protocol used is quite specific, so if they implemented it slightly differently then that might cause issues!

from sia.

I also noticed that my encryption was turned on. I turned it off and I'm receiving this:
bytearray(b'D#0192\x92')

And the exception:
UnicodeDecodeError: 'ascii' codec can't decode byte 0x92 in position 6: ordinal not in range(128)

I don't know anything about the SIA protocol, but I imagine the received line should be a lot longer than that.

from sia.

@Alexwijn give the latest a try, I changed something in the underlying package that might fix this!

from sia.

Thanks for the update. Got the following error now:
Last line could not be parsed as a SIAEvent, line was: D#0192

from sia.

so it seems there is something else going on with your alarm systems, normally a line is a lot longer, do you have some documentation about the alarm system?

from sia.

No, this alarm system came pre-installed when I moved into this house. Did you find out anything out yet?

from sia.

I just noticed but the numbers 0192 are the first numbers of the account id. My account id is six digits long.

from sia.

Also note that the docs give me an example of how the account Id could look like, eg. AAA. But I can only enter numbers not letters.

from sia.

@Alexwijn do you mean you can only enter numbers in your alarm? that should work, but you might not to translate that number to a base16 number (which includes A-E), like here: https://www.rapidtables.com/convert/number/decimal-to-hex.html

from sia.

I'm trying to get this working with Honeywell Flex100 centrale.
2022-04-25 15:17:47 DEBUG (MainThread) [pysiaalarm.base_server] Incoming line: F#123456
2022-04-25 15:17:47 WARNING (MainThread) [pysiaalarm.base_server] Last line could not be parsed succesfully. Error message: No matches found, event was not a SIA or ADM Spec event, line was: %s. Line: F#123456

where 123456 is the account number defined on the Galaxy.
The company that installed the system confirmed that SIA protocol was selected for communication.
Anything I can do at my end to debug this ?

from sia.

@eavanvalkenburg, I've been able to test further and gather some network traces of communications between my Flex 100 and another app.
One communication exchange looks like follow
#123456
Nti10:20/id001/CG
A DEELB.ING
0

Each of the above lines were send separately, and required acknowledgement.

First line is the account number, second line matches a SIA event block, third line is some additional ASCII text, last line is 0 or end of communication.
This messages correspond with the sia_content_regex, but does not get matched.
At least for the account line, because the initial 'F' is included in the pattern matching.
For your information, I've used https://github.com/dklemm/FlexSIA2MQTT to generate the network traces.
Any idea what is going wrong here ?

PS: Or might it be that 4 lines should be concatenated and then matched against the sia_content_regex ?

from sia.

@compunix-be thank you so much for this effort! It indeed looks like it is spreading things out over multiple messages so this gives me a starting point to see if I can build something for this!

from sia.

@eavanvalkenburg did you had time to research this ? If you want me to debug something, let me know.
