Question: Does bresser 7-channel work?

[kroon040]

Hi,

I bought this one https://www.bresser.de/en/Weather-Time/WLAN-Weather-Stations-Centers/BRESSER-Smart-Home-7-Channel-Tuya-Thermometer-Hygrometer.html

The outdoor sensor is the 7006300, is this working?

Hi,

I don't know. I did not have the chance to test this sensor yet. Chances are not bad - the Soil Temperature and Moisture sensor (https://www.bresser.de/en/Weather-Time/BRESSER-soil-temperature-and-moisture-meter.html) which is working is listed in the accessories. But you never know...

Cheers Matthias

BTW: 7006300 is probably the set, while the outdoor sensor is either 7009999 or 7009974.

Hi,

I go to try.

I have an cc1101 a schema that I used a time ago and the print also with a wemos d1 mini

I'm looking for the right config. I think the most are right, only RST, what pin is this on the cc1101?

#elif defined(ESP8266)
    #define PIN_RECEIVER_CS   15

    // CC1101: GDO0 / RFM95W/SX127x: G0
    #define PIN_RECEIVER_IRQ  4 

    // CC1101: GDO2 / RFM95W/SX127x: 
    #define PIN_RECEIVER_GPIO 5 

    // RFM95W/SX127x - GPIOxx / CC1101 - RADIOLIB_NC
    #define PIN_RECEIVER_RST  2
#endif

[matthias-bs]

The CC1101 does not have a reset pin - you can assign RADIOLIB_NC.

Hi,

I can confirm that it works. I only needed to use the mqttcustom.ino, because the other crashed.

I there a default interval of those sensors, I think 1 minute, but I noticed sometimes 1 minute, 2 and also some time more that 10minutes.

Thnx for the nice project

[matthias-bs]

Hi,

Thank you very much for the feedback! Could you please provide the sensor's part number?

Regarding the default interval, it is most likely in the order of 1 minute. For the Soil Moisture/Temperature sensor (7009972) the transmit interval is provided in the manual (1 min). If the interval seems to be longer, some messages could not be decoded due reception errors. You can have a look at this by enabling debug output (just uncomment #define _DEBUG_MODE_ in WeatherSensorCfg.h).

Please also see the Wiki section 'Radio Transceiver Range' for possible improvements.

Best regards Matthias

Hi,

Looking on the sensor it is 7006300 see picture. Looking on de bresser site, it should be the 7009999 (both range 150m)

I also going to flash the bresser station with tasmota.

Thank you very much for this information! May I ask you another favor? Could you please help to find out which protocol the sensor uses? In order to do this, just comment out the line #define BRESSER_5_IN_1 in WeatherSensorCfg. h. If decoding still works afterwards, we know that the 6-in-1 protocol is used.

Hi,

I commented uit de Bresser_5_IN_1, and still working.

I noticed something else. The hostname to MQTT is correct, but in my wifi router the name is ESP_MACADDRESS

I noticed also in another project it sometimes breaks with arduino version of the esp. I'm using 3.0.2 with esp8266

2.7.4 also not correct hostname for network

[matthias-bs]

Hi,

thanks again for testing!

I just googled for "ESP8266 WiFi hostname" and got this hit: https://github.com/esp8266/Arduino/issues/2826

Yes, there seem to be a few issues related to setting the hostname...

Cheers, Matthias

[matthias-bs]

I have one more question: Could you please provide the 'sensor type'? For this I would need some raw output from the debug messages, i.e. some lines starting with "Raw Data: ". Thanks in advance again!

This would allow users to filter receive messages for this sensor type with getData().

IN debug mode, I got errors compiling

[matthias-bs]

Can can you please try to comment out line 692 in WeatherSensor.cpp? Or even better: uncomment the line int chksum = msg[17];

I'll try to fix that in the next release.

Hi,

Is it possible to disable the led on the wemos complete?

Here the debug log

Hi,

thanks a lot again! So the sensor type is the upper four bits of byte[6] (the one following the ID) => 2.

Raw Data:  31 2C 55 01 84 20 ->2<-9 BB BB BB BB B0 04 96 96 BB B0 A5 00 00 00 00 80 10 60 00

You can disable the LED by commenting out this line: https://github.com/matthias-bs/BresserWeatherSensorReceiver/blob/baef2e4126bd922c4c2dcdc92688c72967c676b9/examples/BresserWeatherSensorMQTTCustom/BresserWeatherSensorMQTTCustom.ino#L108

Cheers Matthias

[kroon040]

thanks commenting out worked.
