Particular devices' signals are not getting picked by RFLink

#1 Post by pibi » 19 Apr 2023, 23:06

Hello all,

I am a bit puzzled by a problem I'm having and I have some questions you may be able to answer, hopefully ^^.

For a bit of context, some weeks ago I started trying home automation and installed Home Assistant on a Raspberry Pi, mainly to control some AC and heaters. I am quite a noob with all that so not everything has been easy but overall it has been great fun (and it worked in the end!). Now I'd like to control the diverse RF devices I have and I bought a Nodo RFLink 433.92 gateway. Unfortunately, it is not going as good as I would have hoped ^^'.

Here is a summary of the problem: I have 6 RF thermometers, 1 gate remote and 3 pairs of switches/receptors for the lights of my living room. The 6 thermometers (7 if I count the one from the neighbors) and the remote are recognized brilliantly by RFLink (both under the loader and HA), but the switches are not picked at all, i.e. when I'm pushing a button on one of the switches, the corresponding lamp lights up but nothing is printed in the debug mode of RF Loader.

Here are some info I could get on these switches:
- https://www.amazon.fr/Mengshen-Commutat ... B07Y87Y3Z8
(this is what I actually bought, sorry for the french)
- https://fccid.io/2ANPS-SWNK1R01
- https://chinese-electronics-products-te ... emote.html
Unfortunately, the technical documents are a bit too technical for me to understand for now ^^' .

Anecdotally, RF Loader under debug mode picks some random signals that do not seem to be tied to anything I own, or at least they do not appear when I press the switches.

I tried a couple of basic things to see if something would change, to no avail:
- I reflashed the last firmware (1.48) just in case,
- I tried both plugging directly the gateway on my laptop and with a 9 volts power supply (while having shutdown the Raspberry Pi hosting HA),
- I tried putting one of the receptors in pair mode (through its switch) to see if some signal would be heard (and nothing was heard).

My current hypothesis/questions are the following:
- I have subpar soldering skills and I may have damaged something, or the soldering is just not good enough. But could it be that the gateway is faulty in such a way that some signals are heard and not others?
- Maybe, contrary to what is advertised, the switches/receptors are not exactly at the 433.92 frequency and are thus not compatible (but I guess that would be weird, given the documents above).
- The switches/receptors are indeed at 433.92 MHz but maybe they are working in such a way that RFLink, or the Aurel transceiver, cannot "see" them.
- I may have missed something really obvious and I am not realizing it ^^'.

Would you have any idea of what could be the problem?

Sorry for the long post and thanks!

Thats an expensive piece of hardware.
For such prices I would have moved to some zigbee or wifi switches that offer 2 way communications..
Anyway, I dont know these sets yet.
The frequency indeed seems to be 433.92 and the modulation type would be OOK. Both are supposed to work with the RFLink setup.

Check here https://www.rflink.nl/develop.php what to do with signals that are not recognized yet.
During testing, deactivate as many signals as you can (other sensors) and test the remote at a distance of around 1 meter from the RFLink antenna..

Hey, thanks for the reply.

Indeed they are quite expensive, and clearly with what I discovered since then I would have done things differently. Back then my knowledge of all that was nonexistent and I bought what seemed to be a good solution to my urgent problem. I may change at some point, but for now I'll try to do what I can with what I have.

I'll try to re-do the debug mode experiments tonight taking into account the 1 meter distance (I must admit that I went the other way and tried to get the remote as close as possible), and following the webpage recommendation I will send you a screenshot by email.

Thanks!

Hey again,

So unfortunately I won't be able to send the logs by email, I re-tested and the remote is still not detected.

More precisely: I deactivated all other sensors, tried the remote at a distance of around 1 meter, 5 cm and ~5 meters, and the debug is empty, absolutely nothing is printed. Just in case, I used my car remote to check and it is instantaneously detected.
Bummer :/.

Would you have another idea of what I could test?

Cheers.
