Unsupported Weather Station RF Protocol Sainlogic FT-0835 433Mhz

#1 Post by Joeee » 10 Aug 2020, 12:35

Hi Forum,
i already use RFLink with my homeautomation by the well known nodered flow. However I got a new weather station with a single outdoor sensor. The weather Station is a Sainlogic FT-0835 but without the wlan. I would like to log the values but it seems it isnt supported by rflink. So here is my try to publish the debug logs.
In order to to this is I made my receiver as deaf a possible by removing the antenna and getting it close to the sender. However it seems like it receives something else too. It reads packets with around 200 pulses and packets with around 400 pulses. I think, by observing the display of the station and manipulating the wind direction, that the data is hidden in the 200 pulses packets. I am not sure if the pressure is transmitted wirless or if the sensor sits in the station. I wasnt able to simulate rain, but as the sation has a solar panel and there is no clue in the manual if it charges the 'battery' or even which cells to use i am going to take it appart. When I'm inside the station i could also stimulate the rain or count the impulses of the windspeed sensor.

I investigated further:
- the rainfall is measured by a reed switch which counts the number of buckets filled by the rain
- the wind speed is also measured by a reed switch
- the temperature and humidity seems to be measured by a SHTC3 by Sensirion ( https://www.mouser.com/datasheet/2/682/ ... 323493.pdf )
- the wind direction is measured by two hall sensors aligned 90 degree apart in a circle around a magnet
- as a plus there is the solar cell which is connceted to common gnd and a pin labeled AN0 = so perhaps there is info of the voltage of the cell encoded in the signal
- the PCB is labled on all conncetors except one that look like it is going to accept an ESP8266
- labels are there even for RF Data and the I2C bus of the temp / hum sensor
- on the backside of the pcb there is the circuit for sending, the antenna and the main processor. JP3 seems to be the programming interface with 6 pins (but the signals on it arent labeled)
- a lot of pads arent populated, some bridges arent closed
- on the pcb for the temp hum sensor there is place for a lot more sensors (perhaps activated by the bridges?)

I've got a Pulseview capture of the I2C and RF pin. This is the way i found the datasheet of the Sensor. If anyone needs the capture please write me. I could also provide pictures if anyone is interested.
Greetings

EDIT: Pressure is measured in the basestation.
EDIT: Removed the wrong packages, as reading out the rf signal on the transmitter revealed it sends out the shorter messages, so some cases ore not represented anymore

Re: Unsopported Weather Station RF Protocol Sainlogic FT-0835 433Mhz

EDIT: Was able to compress the thread.

But i have the solution now. With my DVB-t Stick lying around i found rtl_433 to be working with my sensor. It gets recogniced as an Cotech-367959. The description can be found here https://github.com/merbanan/rtl_433/blo ... _36_7959.c . Would someone with access to the sources please be so kind to adpapt this to rflink?
RFlink is so much better than running a host with the dvb stick for all the time.
TIA
Funny sidenote sniffing the I2C bus revealed it is reading the tempature in degrees C but transmitts it in F. :roll:

Hi,
i was wrong with the decoder. Some fine man wrote a working decoder. Please try to implement this into RFLink.

Thanks a lot to all involved.
