Use GPIO pins 0 and 1 for CO2 sensor

[/RaspberryPi]

Hi! I am trying to setup a Pi4 as an in-house air quality monitor with display.
I have the display (SSD1306) connected to physical pin 03 (GPIO2 SDA1) and 05 (GPIO3 SDL1). The display is working fine.
I have connected the air quality sensor (SCD40) to physical pins 27 (GPIO0 SDA0) and 28 (GPIO1 SDL0)... but I can't get the python script to read them.
Based on some googling I have dropped the following in to my /config/boot.txt
dtoverlay=i2c-gpio,bus=3,i2c_gpio_delay_us=1,i2c_gpio_sda=27,i2c_gpio_scl=28 When I run sudo i2cdetect -y 3 it seems to see the device:
0 1 2 3 4 5 6 7 8 9 a b c d e f 00: 08 09 0a 0b 0c 0d 0e 0f 10: 10 11 12 13 14 15 16 17 18 19 1a 1b 1c 1d 1e 1f 20: 20 21 22 23 24 25 26 27 28 29 2a 2b 2c 2d 2e 2f 30: 30 31 32 33 34 35 36 37 38 39 3a 3b 3c 3d 3e 3f 40: 40 41 42 43 44 45 46 47 48 49 4a 4b 4c 4d 4e 4f 50: 50 51 52 53 54 55 56 57 58 59 5a 5b 5c 5d 5e 5f 60: 60 61 62 63 64 65 66 67 68 69 6a 6b 6c 6d 6e 6f 70: 70 71 72 73 74 75 76 77 The error I get is
ValueError: No I2C device at address: 0x62 What am I missing to get this to work? I probably need to hit 0x62 on bus 3 but I can't figure out how to do that.
