The new node works fine too, but unfortunately I get an error, when
a sensor is right at 85 deg C:

hold on, my test was done in a rush, so I forgot to stop the task
reading the temps from the temperature node.
Could that have anything to do with error message?
As long as you have a single owserver process running, there can be
any number of concurrent clients, or even concurrent access via the
same pyownet.protocol.proxy object from different threads… I do not
think this is the problem.
yes, I can confirm, I do use concurrent clients and never had problems.
I was more-so thinking, that owserver might take a sensor 'offline' or
something like that, when a value of exactly 85 deg C is read. When I
then at that time try to read that sensor it might come to this strange
error???
BTW, pyownet.protocol.OwnetError simply reports the owserver error
number (in this case 22) along with the error description available
from /settings/return_codes/text.ALL (in this case "legacy - Invalid
transaction”) and the path that caused the error.
I do get sometimes
/
[Errno 1] Startup - command line parameters invalid:
'28.CF7915020000/temperature'
/but this is rare, so I thought I better not mention it right now - but
hey, now I did ;-)
Me too, I’ve never experienced a 22 error: we need the help of a owfs
wizard.
Yes, let's see what our 'Wizard of OWFS' (aka Jan) has to say to this.
