2 years ago Hi,
the Bresser 6-in-1 protocol provides temperature/humidity and rain gauge data in different messages in an alternating fashion. Reception of sensor messages and transmission of MQTT frames is done asynchronously in Bresser_Weather_Sensor_CC1101_MQTT.
With the current implementation, the MQTT message only provides the contents of the last sensor message and makes no attempt to collect data from multiple sensor messages.
However, when sleep mode is enabled, it is tried to receive all sensor data before going to sleep. (see Bresser_Weather_Sensor_CC1101_MQTT.ino line 1012ff.)
If you prefer to have a complete set of data (even if part of it may be a little bit out-of-date due to reception problems), you could use the flags temp_ok/rain_ok (which aggregates the state; see line 966f) instead of weatherData->temp_ok/rain_ok (which reflects the state of the last message only) to determine which part of the MQTT data to send and reset these flags afterwards.
However, you might want to wait until I add an MQTT example to my all-new BresserWeatherSensorLib!
See BresserWeatherSensorLib/tree/main/examples/BresserWeatherSensorWaiting line 71:
// Attempt to receive entire data set with timeout of 30s
// Try to receive complete set of data, even if data is distributed
// across multiple radio messages.
bool decode_ok = weatherSensor.getData(30000, true /* complete*/);Please note that I could not test BresserWeatherSensorLib yet.
Cheers, Matthias

Hi, I'm using your code on a ESP8266. Works great so far. I own a Bresser 5-in-1 Art-N°: 9602510 (new one), which uses the same protocol as a Bresser 6-in-1. In MQTT i only get a message without rain-data although rain-data is received by CC1101:
