Add-on for Homeassistant

[magicmatt007]

I was using the GPIOs on my Raspberry PI4 to access a mhz19 CO2 sensor via a Home Assistant instance and a suitable integration:

As GPIOs are no longer directly supported since April 2022, I'm looking for alternative ways in accessing mhz19 Sensor directly from the Raspberry PI, on which Homeassistant runs.

As I'm already using the Zigbee2MQTT add-on, I was hoping that MQTT-IO could solve my problem:

1. Is it possible or planned, to make MQTT-IO available as an Add-On for Home Assistant?
2. Is the mhz-19 CO2 sensor supported by MQTT-IO already or planned to do so in future?

Many thanks!
