Support RFT-RF sensor

[meijberg]

Hello,

I am using an HRU ECO 300 R together with Home Assistant Green and the “haithowifi” integration. Everything is functioning well so far, thank you for that.

I do have a question regarding three remote sensors:

RFT-CO2 in the living room

RFT-CO2 in the bedroom

RFT-RF in the bathroom

The first two sensors are detected correctly and provide CO2 (ppm) readings.
However, the RFT-RF sensor, which should provide humidity, temperature, dewpoint and battery values, is not being detected or displayed.

Could you please confirm whether this sensor type is not supported, or if there is a way for me to add or configure it manually?

Thank you in advance for your assistance.

Kind regards,
John
