Hi!
Update:
43hours running with "owread uncached" ZERO error!
the script sleeps 5 seconds then read 7 1wire devices, it takes approx
4.5seconds more, then go to sleep again
So approx 1700*7 readings, no error
When the previous script was reading the directories I got a few errors. So
I believe it's the search-rom algorythm vs the read scatchpad doing the
difference.
As mentioned by Jan it's better to use "owread uncahed"
Well at least for now. I keep monitoring. I've modify the script to check
not only the owread errors but also to check if readings are within
acceptable range. Here is the script.
Tomorrow I'll add a temp sensor...
Wait & see
Best regards
