# Bresser_Weather_Sensor_CC1101_MQTT
**Bresser 5-in-1/6-in-1 868 MHz Weather Sensor Radio Receiver based on CC1101 and ESP32/ESP8266 - provides data via secure MQTT**
Based on:
- [Bresser5in1-CC1101](https://github.com/seaniefs/Bresser5in1-CC1101) by [Sean Siford](https://github.com/seaniefs)
- [RadioLib](https://github.com/jgromes/RadioLib) by [Jan Gromeš](https://github.com/jgromes)

## Weather Stations
* [BRESSER Weather Center 5-in-1](https://www.bresser.de/en/Weather-Time/Weather-Center/BRESSER-Weather-Center-5-in-1-black.html)
* [BRESSER Professional WIFI colour Weather Center 5-in-1 V](https://www.bresser.de/en/Weather-Time/WLAN-Weather-Stations-Centers/BRESSER-Professional-WIFI-colour-Weather-Center-5-in-1-V.html)
The Bresser 5-in-1 Weather Stations seem to use two different protocols. Select the appropriate decoder by (un-)commenting `#define BRESSER_6_IN_1` in the source code.
| Model | Decoder Function |
| ------------- | ------------------------------- |
| 7002510..12 | decodeBresser**5In1**Payload() |
| 7002585 | decodeBresser**6In1**Payload() |
## MQTT Topics
MQTT publications:
`/data` sensor data as JSON string - see `publishWeatherdata()`
`/radio` CC1101 radio transceiver info as JSON string - see `publishRadio()`
`/status` "online"|"offline"|"dead"$
$ via LWT
`` is set by `#define HOSTNAME ...`
`/data` JSON Example:
```
{"sensor_id":12345678,"ch":0,"battery_ok":true,"humidity":44,"wind_gust":1.2,"wind_avg":1.2,"wind_dir":150,"rain":146}
```
## Hardware
(ESP8266 D1-Mini)
### CC1101
[Texas Instruments CC1101 Product Page](https://www.ti.com/product/CC1101)
**Note: CC1101 Module Connector Pitch is 2.0mm!!!**
Unlike most modules/breakout boards, most (if not all) CC1101 modules sold on common e-commerce platforms have a pitch (distance between pins) of 2.0mm. To connect it to breadboards or jumper wires with 2.54mm/100mil pitch (standard), the following options exist:
* solder wires directly to the module
* use a 2.0mm pin header and make/buy jumper wires with 2.54mm at one end and 2.0mm at the other (e.g. [Adafruit Female-Female 2.54 to 2.0mm Jumper Wires](https://www.adafruit.com/product/1919))
* use a [2.0mm to 2.54 adapter PCB](https://www.amazon.de/Lazmin-1-27MM-2-54MM-Adapter-Platten-Brett-drahtlose-default/dp/B07V873N52)
**Note 2: Make sure to use the 868MHz version!**
