Noob question... I got a esp32 and I flashed it with esphome to run a ruuvi tag.

I now also want to run a MH-Z19 sensor to monitor Co2. Can I add the MH-Z19 code from the esphome helper code site to the same esp32 and run both the MH-Z19 and ruuvi on it? or do I need 2 separate esp32's?

Thanks,
Jeff

yes its possible

You should be able to run 2 of the same type of sensor. Look into: uart_id (Optional, ID): Manually specify the ID of the UART Component if you want to use multiple UART buses.
