Then it should be like this i think

[zuckschwerdt]

@nkpap @danrhjones can you test the code in #1225 and report your exact device name/product number with the ID+Status from the output?

[mvdgrift]

I've tested the code in #1225 in combination with my Wi-Fi Colour Weather Station with 5in1 Sensor (Art.No.: 7002580) and it seems to work. Please ignore the UV-sensor value (the weather station is not equipped with a UV-sensor).

The reported ID is: 2030 088d 18

[zuckschwerdt]

Rain is an accumulated (life time) value, so 441.6 seems to match 440.8, right? UV 1650 is ff0, I'll filter that out with the next update.

Can't see a model indication in the ID though, e.g. we have both

• 2030 088d 10 : mvdgrift, Wi-Fi Colour Weather Station with 5in1 Sensor, Art.No.: 7002580
• 1970 0d57 18 : danrhjones, bresser 5-in-1 model 7002580

[mvdgrift]

Minor correction, the ID reported by my weather station is 2030 088d 18 (instead of 2030 088d 10)

[zuckschwerdt]

The 0/8 seems to be a battery indicator, broken out as battery in the output. The lower bits are shown as channel. Not sure if 0 or 8 (=1 in the output) means good or bad battery. Watch out for that and let me know.

[RebeckaJohansson]

My Ventus w835 6in1 gives me ID:1910084d

Still check bitbench. Is there something that have been changed or is this still correct?

Thanks. UV (165 = ff01) is already filtered in the updated version now. Not sure what the data ab01 (=111.0) in the UV field means. It should mean something as the invalid value is ff01 and a valid UV is e.g. 123? (=12.3). But I don't know if a value is missing? ab01 could be 54 (xored with 0xff, like wind and rain) -- but what would 54 be?

My uv index is 0 here. I think something is mabey missing in the code. But i dont know what 🤔

[zuckschwerdt]

You have an UV sensor (which sometimes reads something like 2.3) that should be reading 0.0 but only gives 165 and 111?

[RebeckaJohansson]

Yes, but my uv has been on 0 many days now because of very bad weather. I know that my ventus has

24 seconds loop for temperatur, hum, uv and rain 12 seconds loop for wind data

I dont know if my solar panel that powers the battery on sensor is the same as battery reading.

But i find this information for my outside sensor and my manual book says that weatherdata reads from outside is: Temperature, hum, wind, winddirection, rain and uv

[RebeckaJohansson]

My manual in different language it says two models for my ventus

English is says model W835 Germany is says model C8488A

If i try to connect it to windows i can see in controlpanel and via device and printers i got name C8488

Hi,

I have the new Bresser 5-in-1 (no UV sensor) and I can get its data using the 6-in-1 protocol with the command rtl_433 -f 868.3M -R 172. The station has a pressure sensor, but the data isn't reported. This is what I get:

Hi @m-alzam,

The pressure sensor is part of the base station (not of the remote sensor). That means that the pressure value is not transmitted over the air. And that is the reason why it is not displayed.

I was seeing that same "flag" in the last nibble: https://github.com/merbanan/rtl_433/blob/master/src/devices/bresser_6in1.c#L152 But I'm not sure if that's really the purpose or if this is something else.

Isn't wind in every message, thus 12s? UV is shared with rain, like you write above, thus 12s x2 = 24s, right?

wouldn't it make sense to add in uv_ok "msg[15] >= 0xe9" so it would be something like: int uv_ok = msg[15] <= 0x99 && msg[15] >= 0xe9 && (msg[16] & 0xf0) <= 0x90;?

Not sure about other conditions there, but mine simple humidity/temperature sensor is recognised as 6in1 and it reports UV=0 all the time.

example data: model : Bresser-6in1 count : 1 num_rows : 1 rows : len : 242 data : 096a209019872900000000002226420000fc000001c000000000000000000 codes : {242}096a209019872900000000002226420000fc000001c000000000000000000

Temperature: 22.2 C Humidity : 42 Sensor type: 2

or maybe it would be more safe to do just: if (s_type == 2) uv_ok = 0 ; in my case?

or... something else? ;)

[zuckschwerdt]

From my side it's all just guesswork based on user feedback. Any improved decoding of the fields is welcome.

Is your byte 15-16 inverted? It should be BCD, right? (this won't work msg[15] <= 0x99 && msg[15] >= 0xe9)

[blmpl]

oh, right - it's not :/ would it be then safe just to do: if (s_type == 2) uv_ok = 0 ; can we rely on s_type in this case? I'm quite sure I don't have UV sensor there ;)

[MacH-21]

Hi Christian,

I have been testing 6in1 weather station I find the battery low/ok flag is msg13 bit3, and temperature positive/negative msg13 bit4. I have attached files/pics, Odd the use of bit4 as we can tell it's negative by bcd 999~600( -0.1~ -40) when I use my Transmitter I need to send this bit else the display shows --°c and bit3 Toggles Battery symbol on/off. hope some of this is useful.

Is it possible for rtl_433 to read a set number of bytes, ie: rtl_433-rtlsdr -f 868.3M -R 172 (read in 18bytes after AA2DD4) ?

Thanks! Very interesting. So for the 4 message examples the battery low flag is not always in the channel, but always after the temp? Strange. Does the upper bit in the channel do anything in your tests?

The temperature sign is valuable. We currently just assume that the upper range (>60) is negative, that's a hack.

[zuckschwerdt]

Is it possible for rtl_433 to read a set number of bytes,

The slicer will always give the maximum number of bits possible, with FSK there will always be a tail of 0's where the signal really is already gone.

Hi Christian, The battery flags always seem to be in the Low Nibble of msg13, I have done further tests, including the Remote Temperature/Humidity Sensor - uses more bits in msg13, I will test these bits with my diy transmitter and see what happens on the Display? see attached bitbench screen shots and Text file The text file shows more samples and BitBench links. I am not sure what you are asking re the upper bit in the channel can you please explain further ( I am not the sharpest pencil in the box ;-( ), I want to / will be doing further tests on the Rain, ie: msg12,13,14,15 when flag TX=1.

You have CH:4h in the BitBench, with values of 0 and 8. In the decoder we (wrongly) have BATT:1b CH:3h. I am interested what that (not-really-)BATT bit does. Channel should be 0 (or 1, 2...) but in your example sometimes it is +8 -- what is that?

[MacH-21]

When I reset my outside weather station it Tx's as "18" or "10" s-type=1, ch=8 or chan=0 All the Stations bar one that have reported on (bresser_6in1.c) seem to be "18" there is no channel "8"

Also I have noticed with my Remote Sensor which can be set to ch=1 through to ch=7 can Tx "21,22,23,24,25,26,27" or "29,2A,2B,2C,2D,2E,2F" s-type=2, ch=1 through to Ch=7 I will test this further...

I believe you have already cracked this one. bresser_6-in1.c 139 int s_type = (msg[6] >> 4); // 1: weather station, 2: indoor?, 4: soil probe 140 int batt = (msg[6] >> 3) & 1; 141 int chan = (msg[6] & 0x7);

Therefore 8 equates to 0, 9-1, A-2, B-3, C-4, D-5, E-6, F-7 // line 140

When I reset my outside weather station it Tx's as "18" or "10" s-type=1, ch=8 or chan=0

Ok! That explains it. We sometimes see a "manual transmit" or "new startup" flag. That would be the 8. Thanks!

[zuckschwerdt]

Added as startup flag with ed37452 now.

@zuckschwerdt I have been doing tests on the flags?? and a few other things so far for the 6in1 weather station my tests show Flags for Battery status Temperature positive or negative therefore we can use this instead of the hack (>60) I have tweeked bresser_6in1.c and run tests all data is displaying on the internal display ok and Myrtl_433.exe works fine I show the full Rain to 3 decimals as the increments are 0.254mm per bucket tip I have also included all *.cu8 files please see attached file for more info on tests and findings

[MacH-21]

Can users of the 5in1 stations report the resolution of rain? When I test some *cu8 files I see 0.4mm and sometimes 0.254mm, my 6in1 = 0.254

my bresser 7002580 is not working on hass os, I'm using freq 868.30 with protocol 172-173 but nothing has been found. please help

[zuckschwerdt]

That number is of the head unit /station, not a sensor. https://triq.org/rtl_433/ANALYZE.html and upload a sample as zip here.

[mebitek]

my station is this one: https://www.bresser.de/it/Ora-Tempo/Stazione-meteo-a-colori-BRESSER-Wi-Fi-con-sensore-professionale-5-in-1.html?mtm_campaign=Doofinder&mtm_kwd=7002580&mtm_source=Italian&mtm_medium=OnSite&mtm_cid=Italy&mtm_group=SiteSearch

[zuckschwerdt]

Yes, new Bresser 5-in-1 sensors use the "Bresser-6in1" decoder. Grab a sample, drop on https://triq.org/pdv/ to make sure it's good, then upload here.

It seems a PR was merged. Can someone test with git master, or confirm that we should close this PR?

[alcarazzam]

Hi @gdt,

I remember testing rtl_433 with a new 5-in-1 (which uses the 6-in-1 protocol) and worked perfectly fine. See this comment.

[gdt]

Thanks - we'll call this fixed and if there is a bug with current master, someone can open a fresh issue.
