Not receiving TFA 30.3125

[ch-world]

I tried to receive data from my TFA 30.3125 weather sensor but the data is not being displayed on the serial console.

Here is an uploaded doc with infos about the protocol: https://forum.pilight.org/Thread-TFA-30-3125-Temp-Hum-TFA-31-3120-90-Temp?pid=15169#pid15169

I can receive it with this code: https://github.com/guillier/433mhz_receiver and RFControl receives other senders from the neighborhoud.

Edit: I'm using the version bundled to homeduino.

Hello ,

has now someone found out why that does not work?
possibly. because follow Temp and Hum always directly behind the other, with a long ca.28ms footer?
I have the same problem sometimes is temp and sometimes hum, but never both in succession, as they are sent.

@sweetpi, @Icesory, I've been looking to add the TFA 30.3125 to my setup using Homeduino as well. After some testing the sensor appears in the debug overview very rarely (compared to how often it sends) with pulse lengths like [ 512, 1164, 29020 ]. Other sensors and switches can be received fine. Could it be that RFControl does not recognise the signal?

@jochem725 Which driver are you using in your setup for RF? Serialport or GPIO driver? Which receiver do you use?

[jochem725]

@mwittig I'm currently using the RXB6 connected using the serialport (Arduino Nano).

Hello ,

I am using Serialport connect to an Arduiono Nano too and have the same Problem. See the last post from me.

[jochem725]

@Schroedi71 Temperature seems to be received more often (about 2 times per hour), humidity even less. Sometimes there is no humidity update for over 4 hours, while the sensor sends very often. Looking at the protocol (http://www.f6fbb.org/domo/sensors/tx3_th.php) there are two separate packets sent quickly after each other. Do you see the same behaviour?

I have the same issue. Arduiono Nano, RXB6 and TFA 30.3125. No data is received on serialport. Homeduino is up to date. Could somebody solve the issue?

[Schroedi71]

Hello Nona00,
I have adapted the Homeduino firmware. It works satisfactorily with it. The protocol is Weather17 and has since been added to the Pimatic plugin. See pimatic/rfcontroljs#108. I did not upload the Arduino firmware because I can only test my existing RF433 devices. And also just "hobby programmer" am. If you want to try them, I could make them available to you. But without guarantee :-)
Unfortunately I have to translate everything with Google.
Do you happen to speak German?

Best regards,
Frank

Hallo Schroedi71,

ja ich spreche Deutsch :-) Also Weather17 habe ich zur Auswahl bei pimatic, aber wie gesagt es kommen keine Daten vom Arduino (müsste auch erst mal die ID des TFA herausfinden). Prinzipiell funktionniert der RXB6 schon am Arduino, die Signale der 433Mhz Elro Steckdosen kann ich empfangen.

Es würde mich sehr interessieren, was du an der Homeduino Firmware modifiziert hast.

[Schroedi71]

ok, ich kann sie Dir per Mail zum testen schicken.
Nur bitte nicht veröffentlichen, da ich wie gesagt nur für das TFA 30.3125 Modul getestet habe. Ich habe nur die "Empfindlichkeit herunter gedreht" (weniger Paketvergleich, das Modul nur 2 oder 3 pakete sendet und Hum gleich im Anschluß)
@mwittig or can you test it ?

Hast du eine Mailadresse für mich ? Ich glaube PN geht hier nicht oder ??

Hallo Schroedi71,

Werde es dann testen. Danke schonmal!

I tried the patched homeduino firmware of Schroedi71. The weather values are now received each 2 minutes, but I'm not able to get humidity very often with TFA 30.3125. I receive only 2-5 humidity values per day. Seems to be an issue with the homedunio firmware.
