Adding support for Bresser 3CH weather sensor (Lidl)

Harald654

Hello,

would it be possible to add this weather sensor: Bresser 3CH (offered by Lidl in Germany) to the rfcontroljs module
resp. pimatic-homeduino?

The protocol/data for decoding:

https://github.com/merbanan/rtl_433/blob/master/src/devices/bresser_3ch.c link text
or:
http://forum.iobroker.net/viewtopic.php?f=35&t=3831&p=35623#p35623 link text

Greetings,

@Harald654 Do you already have this device at hand? If yes, please create some debug data with pimatic-homeduino.

leader21

with some luck this is already supported

thanks for the answers,

I have three diveces at hand (so i can test all three channels of the divces togehter).
But somehow pimatic does not seems to receive any signals.
My config:

Even if I transmit signals with my radio remote control, pimatic displayed nothing in the GUI under “Log” - “Messages”.
Does someone recognize what I do wrong?

please check the howto number 4 part 2
https://forum.pimatic.org/topic/202/4-homeduino-433-mhz-sending-receiving-and-even-more/2

i guess there’s a problem with your pin numbers on the homeduino plugin.
first you should check to which gpio your receiver is attached to (should be GPIO17 as shown on the picture) then change the receiver pin to 1.

also pls. keep in mind that the raspi gpio is only capable of 3v3 !

I bought the same weather station and this should be the debug output I have.

i changed recive to pin 1, but I still do not receive any signals on the blog page.
Since the reciver works if i do not read it with pimatic, I think the problem is by my settings.

here my start-debug, is the invalid cors settings a problem?

Can you send me your config and plugin settings?

leader21

cors should be of no problem. you can delete the cors entry in the config.json
have you checked the correct gpio on the pi?
also you need to check the voltage as stated above! the pi can only handle 3v3 on the gpio. if you power the receiver with 5v the data line may have 5v too!
the best way for 433mhz RF is the arduino solution with the flashed homeduino sketch.

Hello leader 21,

yes i have checked the correct gpio to the pi (i changed to the corresponding pins in your tutorial).

I recorded the raw data of the sensor , which I receive with the pi:

So i tihnk my recviver works correctly.
What would I get for a debug entry if pimatic does not recognize the sensor or can not start with the received data?
Would I get an entry at all?

Greetings,

I also have one of these sensors. I was able to add it to the RFLink package without much trouble and it works fine there. I also cannot get it to show up on my arduino with homeduino. I think the problem is the initial pulse.
In thise protocol there is a series of 8 pulse (10101010) with a duration of 750-100us. I think the RFcontrol library cannot pick this protocol up as written.
