EDIT:
problem solved, issue was between chair and controller. No hardware issue, I connect all 3 temp sensors to sensors ports instead of temp.
And there is lag between disconnect and update of dashboard which looks like sudden disappear .
Sorry for false alarm.

Hi,
I have strange issue - my 3 temp sensors disappeared from dashboard and I guess are not detected on I2C:
result of i2cdetect -y 1:
0 1 2 3 4 5 6 7 8 9 a b c d e f
00: -- -- -- -- -- -- -- -- -- -- -- -- --
10: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- --
20: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- --
30: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- --
40: 40 -- -- -- -- -- -- -- -- -- -- -- -- -- -- --
50: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- --
60: -- -- -- 63 -- -- -- -- -- -- -- -- -- -- -- --
70: -- -- -- -- -- -- -- --
it happened during normal operation.
I have 3 temperature sensors DS18B20 plugged in sensor 1,2,3 ports. No PU or PD jumpers in place
It works well, only change I did was changing name in database for them via phpmyadmin but it works even after this change.
Ph sensor is working - so I2C is working.
I try to disconnect all 3 sensors - restart, power off, connect 1 sensor ,power on - no success, try all 3 separately to assure it is not problem with 1 of them - same result :(
Any hint what to test next please?
Thank you in advance
Karel
