(Switzerland) 💫 Successful HA Integration with Integra Aquaradio Smart & nanoCUL

[Z3r10]

Hello all,

I would like to kindly share my little success of the day 🤩:
I live in Switzerland, and I successfully got communication with my Integra Aquaradio Smart Meter, composed of the folowing:

• https://ch.integra-metering.com/fr/product/aquastream-m-bus-2/
• https://ch.integra-metering.com/fr/product/aquaradio-smart-m-bus/

I bought a nanoCUL M-Bus Adapter: https://smart-home-komponente.de/en/products/nano-cul-868-mbus

It went far more easy than expected:

• Installed the HA Add-on
• Plugged-in the nanoCUL, forwarded the USB to the HA VM
• Started the add-on
• Instantly found some telegram from my meter
• Finalized the config via the add-on WebUI: no key was even required! 🙌
• MQTT device showed right away!

I was prepared to spend hours, even that it would simply not work at all!
I would like to warmly thanks all the team behing this project, it is really wonderful! 🙏

✅ Please add my meter to the compatibility list,
I found another Integra meter, that's what gave me the courage to try 😊

Some News:
Apparently there is a x100 factor to add.
The value reported is 100x smaller than the real value.

I will somehow correct it with a value template in HA, but maybe there is a better way to fix it before the MQTT conversion?

✅ I fixed it elegantly, by overriding the *total_m3 values with calculations.

Not sure if the standard field override is supported, as it is not documented, but it works!

Also, by using additional field (ie: corrected_total_m3), such fields are not included in the MQTT discovery.

NB: the "factor" unit is not documented in the calculation documentation, but I found it in an issue
