How can I Integrate MarQuant 014331 Weather Station with home assistant ?

Seems to be supported by RTL_433 as:
[215] Emax W6, rebrand Altronics x7063/4, Optex 990040/50/51, Orium 13093/13123, Infactory FWS-1200, Newentor Q9, Otio 810025, Protmex PT3390A, Jula Marquant 014331/32, Weather Station or temperature/humidity sensor

It uses FSK modulation which is not supported out of the box with OpenMQTTGateway with v1.6.0

/** @file
    First version was for Altronics X7064 temperature and humidity sensor.
    Then updated by Profboc75 with Optex 990040 (Emax full Weather station rain gauge/wind speed/wind direction ... ref EM3390W6 )

Nevertheless, if you are open to tinkering and building your own firmware, you can do it as done below:

If not a further version of OMG will support FSK out of the box

Thanks, I will try merbanan/Rtl_433 .I have ordered cc1101.

We got feedback about rtl 433 FSK working with sx127X chipsets but did not receive feedback for cc1101.

Is this SX/XL1278 compatible ?

With the first model - the blue one - it’s a bit of a pain to solder with the narrow 2.0mm pitch.

My preferred solution for an rtl_433 gateway would be a LilyGo TTGO LoRa32 V2.1_1.6.1 433MHz for your case.
