well that might be good, since I set everything up I not even getting reliable numbers for Temperature.
Since yesterday I also have lots of 0 values again, Im OK with 1 or 2 but those are again every 4th or 5th reading.
Running the main python script I am also getting this error:
Raspberry Pi= 2017-07-10 07:58:58
No handlers could be found for logger "apscheduler.executors.default"
[Errno 121] Remote I/O error
File "/usr/local/lib/python2.7/dist-packages/apscheduler/executors/base.py", line 125, in run_job
retval = job.func(*job.args, **job.kwargs)
File "GroveWeatherPi.py", line 1220, in sampleAndDisplay
print "DS3231=\t\t%s" % ds3231.read_datetime()
File "./RTC_SDL_DS3231/SDL_DS3231.py", line 151, in read_datetime
return datetime((century - 1) * 100 + self._read_year(),
File "./RTC_SDL_DS3231/SDL_DS3231.py", line 128, in _read_year
return _bcd_to_int(self._read(self._REG_YEAR))
File "./RTC_SDL_DS3231/SDL_DS3231.py", line 93, in _read
returndata = self._bus.read_byte_data(self._addr, data)
and here the last one:
Raspberry Pi= 2017-07-10 08:01:48
day is out of range for month
File "/usr/local/lib/python2.7/dist-packages/apscheduler/executors/base.py", line 125, in run_job
retval = job.func(*job.args, **job.kwargs)
File "GroveWeatherPi.py", line 1220, in sampleAndDisplay
print "DS3231=\t\t%s" % ds3231.read_datetime()
File "./RTC_SDL_DS3231/SDL_DS3231.py", line 153, in read_datetime
self._read_minutes(), self._read_seconds(), 0, tzinfo=tzinfo)
Thanks

"Running the main python script I am also getting this error:
I get thone same errors, but only when running the main script from a shell without killing the process first (while the main script is already running). I was assuming it was because the background script had the files open and locked when the shell script tried to access them.

Good suggestion Robert!
If that doesn't help, then go downing to the SDL_Pi_TCA9545/ directory and run
sudo python testSDL_Pi_TCA9545.py
and compare the results to the ones given in the tutorial or instructable.
This will pick up a bunch of wiring errors. Post the results, but do your own comparison first and give us the results.
Best,
BP

I am getting those errors also when I kill the main pythin script, but I have to say its not always the case so the reason could maybe be "locked files".
running testSDL_Pi_TCA9545.py shows me the following:
-----------BUS 0-------------------
tca9545 control register B3-B0 = 0x1
ignore Interrupts if INT3' - INT0' not connected
tca9545 control register Interrupts = 0x4
0 1 2 3 4 5 6 7 8 9 a b c d e f
00: -- -- -- -- -- -- -- -- -- -- -- -- --
10: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- --
20: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- --
30: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- --
40: -- -- -- -- -- -- -- -- 48 -- -- -- -- -- -- --
50: -- -- -- -- -- -- -- 57 -- -- -- -- -- -- -- --
60: -- -- -- -- -- -- -- -- 68 -- -- -- -- -- -- --
70: -- -- -- 73 -- -- -- 77
48: analog to digital converter
57: *cant find this in the I2c chart*
68: real time clock
73: 4 channel bus mux
77: Barometer
I think the wiring looks good....
Whats the recommended procedure to unlock locked files ... if sudo kill -9 <ID> doesnt do it?
thank

I think 0x57 is the EEPROM on the RTC Board.
Locked files? Hmmm. Maybe the OS is locking the I2C bus? I have never had that experience.
Check carefully that you don't have two copies running.
