cant seem to read software version

[arjepsen]

Hey.
I got a Nilan VP18 heatpump, and your files works great for the most part - thanks for sharing!
One small issue I have, is that I can't seem to get the major, minor and versionrelease software version.
For the life of me I can't figure out why, but when I try to use the functions to read those values, I get "null".
Any help?

Regards
Anders

Hi Anders,
Unfortunately, I have the same problem. I think it is due to the data type text. Probably these fields have a different register size than Nilan_Bus_Version. I stopped trying after a few attempts because the version was not so important to me. Here are some good starting points:

• Nilan documentation: comfort-300-top
• The services config file modbus.cfg.
• The script readNilan.py
  • reads the registers correctly
  • uses minimalmodbus.read_string on text values instead of minimalmodbus.read_register - maybe there it is possible to determine the difference.

Hey – you managed to get me thinking. I’m not too much into all the programming stuff, but I started wondering why the registers would be read wrong. There’s a mentioning of “2-character ascii text”, which got me thinking. For a quick test, I changed the type to “uint-8” instead of the default uint-16 And whaddayaknow Now it lists major version: “2.” minor version “36” Now the last value ought to list as “.a” But that one isn’t working (yet). Will fiddle som e more with it. Thanks.

Did you get it?
I was wondering if that last version part "a" is really wrong or if it is their normal Version Schema.
I tried your suggestion with "utf8" but unfortunately that doesn't work for me. I am still getting "-".
I would appreciate a pull request or code snippet with your changes. Maybe there is a difference in the sitemap or items config, too?

Best regards

Actually, I don’t think I got it anyway. I managed to get openhab to show the software numbers – same as on the small controller for the Nilan heatpump. However I then ran into some trouble around the changes I made to the config files didn’t seem to “take”. There seems to be a cache somewhere, and I couldn’t quite reset that, so I ended up simply reinstalling the whole OS and openhabian. (I’m running it on a nanopi neo +2) After I reinstalled, I couldn’t get it to show those numbers again L I think the reason openhab was able to show them in the first place, is related to me first using the python scripts to read those numbers. But on my new installation I’m having trouble with the whole python and pip setup. Hope this info can help.
