device_class not propagated as expected to MQTT

[pvyleta]

Description

I hope this is not a rookie mistake, but I am lost after several hours of trying.

I want to properly show the values of my Heat Recovery Unit in HomeAssistant with the right category of data, e.g. for carbon dioxide, I want them to be shown as such. For this I made change in mqtt-hassio.cfg in type_switch-number

type_switch-number =
    sensor,,total_increasing = poweron|count,
    sensor,temperature,measurement = temp|,°C$
    sensor,temperature,measurement = temp|,K$
    sensor,power_factor,measurement = power*%%
    sensor,power,measurement = power|,kW$|,W$
    sensor,voltage,measurement = volt|,V$
    sensor,current,measurement = current,|,A$
    sensor,,measurement = integral|,°min$
    sensor,energy,total_increasing = energy|,Wh$
    sensor,yield,total_increasing = total*,Wh$
    sensor,duration,total_increasing = hours|days|,h$
    sensor,,total_increasing = starts*,$
    sensor,pressure,measurement = bar$|Pa$
    sensor,gas,measurement = gas*/min$
    sensor,gas,total_increasing = air*total*,m³$
    sensor,volume,total_increasing = total*,m³$
    sensor,volume,measurement = m³$
    sensor,volume_flow_rate,measurement = m³/h$
    sensor,carbon_dioxide,measurement = *co2*,ppm$
    sensor,humidity,measurement = humid*%%$
    sensor,, =

This does work for pressure, duration and volume, however, my added definition for gas (air*total*,m³$), volume_flow_rate (m³/h$) and carbon_dioxide (*co2*,ppm$) is failing to be picked up, as can be seen from the default icons here:

but mainly from the logs:

Actual behavior

"device_class": is missing from the published value type

Expected behavior

"device_class": is present based on the pattern provided in type_switch-number

So far, I identified that *co2*,ppm$ does not work as expected for me, but co2*,ppm$ does - the star sympol will apparently not match the beginning of string which is quite different to other regex implementations. Woudl it be possible to unigy the behavior?

For the others, I made no progress whatsoever in decoding the issue.

from the docs here and here:
"*" matches a single arbitrary length wildcard part in the middle
as such it is not supposed to be more than once per entry, i.e. "ab" is similar to regexp "a.b", but "abc" does not work.
