Hi
I have 2 x SCD30 sensors on separate I2C busses due to not being able to change the sensors address (hardware set permanently at 0x61).
I have added 2 new busses at /dev/i2c-3 & /dev/i2c-4
~$ sudo i2cdetect -y -l
i2c-3 i2c 3.i2c I2C adapter
i2c-1 i2c bcm2835 (i2c@7e804000) I2C adapter
i2c-4 i2c 4.i2c I2C adapter
They both return addresses successfully
pi@mypi:~$ sudo i2cdetect -y 3
0 1 2 3 4 5 6 7 8 9 a b c d e f
00: -- -- -- -- -- -- -- -- -- -- -- -- --
10: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- --
20: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- --
30: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- --
40: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- --
50: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- --
60: -- 61 -- -- -- -- -- -- -- -- -- -- -- -- -- --
70: -- -- -- -- -- -- -- --
pi@mypi:~$ sudo i2cdetect -y 4
0 1 2 3 4 5 6 7 8 9 a b c d e f

10: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- --

50: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- --
60: -- 61 -- -- -- -- -- -- -- -- -- -- -- -- -- --
70: -- -- -- -- -- -- -- --
However I can't connect to either of then via the scd30-cli to alter any configuration parameters as the command line bus number option always returns error as below:
pi@mypi:~$ scd30-cli -b 3 status

Same error for bus number 4
Is this a bug or am I providing the bus number in the wrong format?
