I'm trying to run 2 BME680 on the same i2c bus via master/slave (both sensors recognized by Pi on adresses 0x76 and 0x77).
Set up 2 inputs with the respective adresses in mycodo, but the slave sensor is not giving any measurments. The logs are showing the following:

Versions:
Mycodo Version: 8.5.13
Raspberry Pi Version: [e.g. 3B+] Raspberry Pi 5 8 GB
Raspbian OS Version: Debian 12 - 6.6.31+rpt-rpi2712
Reproducibility
always the same if you deactivate/activate it.
Expected behavior
Since the logs show something regarding the slave sensor doesn't get a unique name and probably that's the reason it can't be used probably, I would expect that "the logic" gives it a unique name in the initialization process for it to run properly.
