JMaurin,
Thanks for all your help and diligence here. It is always hard to help when we can't duplicate the problem!

I've had a similar issue. The sensor works fine when the MUX isn't installed, but it doesn't work with the i2c MUX. I think the issue is that the sensor needs a little time to calibrate and the bus is constantly switching out from under it since the while true main loop switches to bus 0 every second. That being said, I've tried duplicating the sample test code for the SI1145 inside GroveWeatherPI and disabled all the timers so that only sampleAndPrint is running and also disabled the 1 second reset to bus 0 in the main loop and I'm still getting 0s. Are you able to get it to work with the I2C Mux at all?

OK. We had a problem with the SI1145 in version 2.97, which I see you have. Update to 2.99 so we are on the same version.

Checking the README.md after a git pull only shows 2.98. Version 2.98 www.switchdoc.com/November 18, 2017 - Adjusted Lightning Detector detection for 0x02 or 0x03 November 16, 2017 - Fixed name clash with latest OS version |

Misky,
We need to duplicate this problem. We have added it to our bug list.

Hi again. Version 2.99 and detection of sensor is working fine by now. But the values are totally wrong! -----------------
Sunlight Vi/IR/UV Sensor
-----------------
Sunlight Visible(Lux): 26752.46
Sunlight IR(Lux): 26754.92
Sunlight UV Index: 349.74
Whilw running the example code from here ( github.com/THP-JOE/Python_SI1145 ) the values are fine (in the same board, same place, same time/day) pi@skyweather:~/Python_SI1145/examples $ python simpletest.py
Press Cntrl + Z to cancel
Vis: 528
IR: 2898
UV Index: 1.45
Vis: 528
IR: 2906
UV Index: 1.45
Vis: 529
IR: 2914
UV Index: 1.46

Is it out in bright sunlight? There are gain variables set in the software that may be different in each version of the software.

Day.....but the values are way too different, isn't?

This is a very sensitive device and has gain variables of over 100 to one, so it looks kind of right. We have one down in Project Curacao that reads up to the limit (like yours does) in bright sunlight.

In sunlight I always get a reading of 349.74. At night this does drop to 0.0
Is there a calibration or is something totally wrong?

We will try to duplicate your problem when I get back to the lab next Tuesday. This has GOT to be a software problem of some kind in GroveWeatherPi. Your testing proves that.

check again. Version 2.99 is up there now. BP Where do I get 2.99??
On GitHub I only see 2.97. I am having issues getting this sensor to work
github.com/switchdoclabs/SDL_Pi_GroveWeatherPi/tree/master/SDL_Pi_SI1145
simple test output Traceback (most recent call last):
File "simpletest.py", line 41, in <module>
sensor = SDL_Pi_SI1145.SDL_Pi_SI1145()

self._device.write_byte_data(SI1145_ADDR,SI1145_REG_MEASRATE0, 0)
IOError: [Errno 121] Remote I/O error
I can see the device on 60 on Bus 3
