Remote I/O

Hello,

I have a PI running from 5 days without any issue regulating a temperature in a small garden room (hotroom ?).

This night I have the following error :

Traceback (most recent call last):
File "/home/pi/Documents/Python/Temperature/RegulHumidLumino.py", line 81, in
temp = str(temperature) + '\t' + str(temperature2) + '\t' + str(temperature3) + '\t' + str(EtatChauffage) + '\t' + str(Lux.value) + '\t' + str(Hum.value)

OSError: [Errno 121] Remote I/O error

If I understand well the I2C slave was not seen, but, I run again this morning this application without issue.
So I am confuse of what is appnening !

Can you help me on this subject ? How can I have more precise idea of what was appining this night ?

Thanks you,
Jean-Marie

I write this message not a the good level, but not such where to place it ... and I don't see the possibility to move it.

Can an administrator move this message to a better place if needed ?

Sorry for the unconvenience !
And thanks you for your help
Jean-Marie
