V7/V13 UDP protocol client in python
« Dato: Nov 30, 2015, 14:17 »
Jens told me that the new UDP protocol for local communication with the V7/13 box is nearing final, so if you have an updated V7 box you can try to talk to it with a test program I put up on github. It's written in python so it works on windows/mac/linux (and with some effort http://pythoncentral.io/python-for-android-the-scripting-layer-sl4a/ on android).  The test code implements a simple command line client that sends one request to the controller and prints the response.

https://github.com/motoz/nbetest

Use like this:

Kode: [Vælg]
python client.py -a address -p password functioncode payloador
Kode: [Vælg]
python client.py -v -a address -p password functioncode payloadfor a more verbose output.

If the address is left out the controller is discovered automatically on the local network

NBE kindly provides a public test box on v7testbox.stokercloud.dk with password 6464111183 that I have used to test the code since I don't (yet) have a V7 controller.

Read some settings from the text box:
Kode: [Vælg]
python client.py -a v7testbox.stokercloud.dk -p 6464111183 1 boiler.*
You need python installed which can be downloaded here https://www.python.org/downloads/windows/. Both 2.7 and 3.5 work fine.

Ask Jens "BoinkUser" for more details on the protocol if you are interested.

Hi Motoz

Thats just splendid  8)

Works like a charm.

Yes, any questions just ask, we also have Android code and Java (PC/Mac/Linux you name it) code, that are free for any interested. Anyone particulary interested in iOS we also have that. But Motoz' code is also a good choice for your preferred platform.

Regards Jens

Now I have a V7 box to play with...

Looks like the latest released (not beta) firmware has an older version of the protocol (no sequence numbers). I made a change to the nbetest client so it works with 7.0612 when using the --noseqnum option on the command line:

Kode: [Vælg]
python client.py --noseqnum -p xxxxxxxxxx 4 *
time=22120
boiler_temp=22.2
smoke_temp=999.9
return_temp=999.9
dhw_temp=999.9
external_temp=999.9
forward_temp=999.9
t7_temp=999.9
distance=0
photo_level=0
shaft_temp=999.9
milli_ampere=0
oxygen=15.4
...

On linux and mac you need to escape the wildcard character '*' (otherwise the shell will expand it to filenames from the current directory):
Kode: [Vælg]
python client.py --noseqnum -p xxxxxxxxxx 4 \*
This is fun... ;D

I fleshed out the test client a bit yesterday. Now there is a 'get' and a 'set' command and a 'raw' command to send raw frames as before.
Kode: [Vælg]
$ python client.py get

$ python client.py get settings/auger

settings/auger/auger_50=12.9
settings/auger/auger_100=21.9
settings/auger/kw_min=6.0
settings/auger/kw_max=23
settings/auger/runs_minute=6
settings/auger/min_dose=5.0

Kode: [Vælg]
$ python client.py get settings/auger/auger_capacity
2200

And set:
Kode: [Vælg]
$ python client.py set settings/auger/auger_capacity 2300
OK

As you may have noticed the controller does not (yet?) check that the password supplied is correct so it can be skipped.

Looks nice, I could not get the client to work though.
My firmware is currently v7.0522, but I dont think it got sofar as to actually talk to it.

You need at least 7.0612, I don't think there is any UDP protocol support at all in 7.0522. With 7.0612 it should work without sequence numbers, and above that with sequence numbers. The error exceptions are not handled at all in the test client, so when it does not work it just errors out as you noticed. Cool that you are testing it.

Updates to v7.0612 today, but what is the correct command to get some data from it?
The python scripts to fail too fast for it to be actual network exchange with a host it needs to detect first.

With 7.0612 you have to add the option --noseqnum to the command line, eg:
Kode: [Vælg]
python client.py --noseqnum getreturns:

and
Kode: [Vælg]

settings/bbq_grill/
settings/bbq_meat/

settings/bbq_div/

and
Kode: [Vælg]
python client.py --noseqnum get settings/boiler
returns:
settings/boiler/temp=62

settings/boiler/reduction=10

settings/boiler/friday=000000000000
settings/boiler/saturday=000000000000
settings/boiler/sunday=000000000000

Kode: [Vælg]
python client.py --noseqnum get settings/boiler/tempreturns only the temperature, and so on.

In the gui program you can type eg. 'get settings/boiler' in the input field and click the 'run command' button. The 'seqnums' checkbox need to be unselected on 7.0612

This is only for testing the protocol so far (which probably isn't still final), so it's not that useful yet but something to play with.

Did it fail just once? It says 'timeout', ie no answer. Could be a temporary network problem, or a glitch in the controller. There is no error handling int the test client, so it just quits with an unhandled exception on any problem.
Or did you upgrade the controller firmware?

No It has been running in a crontab every minute, but has failed since around 2pm, I only just disabled the crontab since I was getting no sensor data and went to check on it.
Firmware is same as last, it was the latest I could select, v7.0612, not sure if there is a newer one now that I have upgraded.

The error will probably go away if I restart the boiler.

I remember Jens said that there was a problem like that in some version, it just died and needed a restart. It's possible it's still in 7.612, I don't remember when it was fixed.
