Hi @HiFiJ
Not sure if you have given up completely already, but I am having success with my Froggit weather station, which looks exactly the same as yours, but requires setting the frequency to 868.35 MHz
'-DOOK_MODULATION=false' ; FSK modulation activated
'-DRF_FREQUENCY=868.35'
then the MQTT messages coming in with
{
"model": "Fineoffset-WH65B",
"id": 52,
"battery_ok": 1,
"temperature_C": 18.1,
"humidity": 48,
"wind_dir_deg": 281,
"wind_avg_m_s": 0,
"wind_max_m_s": 0,
"rain_mm": 0,
"uv": 1,
"uvi": 0,
"light_lux": 0,
"mic": "CRC",
"protocol": "Fine Offset Electronics, WH25, WH32B, WH24, WH65B, HP1000, Misol WS2320 Temperature/Humidity/Pressure Sensor",

}
Hope this helps with yours as well.
