Smoke alarm Nexa LM-101LC

Hi there!
New user of NetHomeServer. This far its looks really good to build up some cool stuff with.
I have some smoke alarm detectors model Nexa LM-101LC.
Connected to each other true RF 433.92MHz. If one detects smoke all connected will start warning.
Under "Create new Item" I see thats it say's "NexaSmokeDetector". Also under Settings > Installed Protocol Encoders/decoders can read "Nexa Fire",
Was thinking NetHomeServer should manage to detect them when alarm goes on. But nothing at all under "Received Events".
In the manual from Nexa Fire and Safety it says Compatible with KD-101LA. Also have a other number Nexa 13319-CPR-001.
Anyone that get it working, or have any ides?
Regards
Fred.

Maybe this is the problem?
I check under hardware in NetHomeServer and on my Tellstick duo.
When I check under "ReceivedProtocols" Nexa fire is not there. Under "TransmittedProtocols" Nexa fire is showing.
I tried to add it under "ReceivedProtocols" but can not see Nexa Fire there, and there for can not add it.
Is it not possible to add Nexa Fire under "ReceivedProtocols"? or how to make it happend?
Regards
Fred

Well unfortunately the Tellstick does not support reception of the Nexa Fire protocol (as far as I know). When OpenNetHome transmits via Tellstick, it bypasses the Tellstick's firmware and does the encoding itself, therefore it can send any protocol via Tellstick. On reception however the Tellstick firmware has to know the protocol in order for OpenNethome to receive it. The only way to receive it right now is by building your own receiver (
http://wiki.nethome.nu/doku.php/homehw) and use OpenNetHome's own decoder. Sorry...

Thanks for answer.
Ahh ok I see, so it is the limitation on receive in Tellstick that is the problem.
Sounds like I need to find some other hardware than Tellstick for make it work.
Auriel Transceiver/receiver that Walter Krämbring built sounds interesting. Or only the receiver. Is it possible to have Tellstick for transmit and a other hardware to receive?
I use Raspberry Pi as hardware for operative system.
Is there any prebuilt hardware to buy or only way to get it, is to build a own?

Yes it is possible to let Tellstick transmit and have your home built receiver receive, OpenNetHome even allows multiple transmitters and receivers at the same time. You will however have to warm up your own soldering iron in this case, because there are unfortunately no prebuilt hardware.

Obviously
I have exactly this setup (my own built receiver and a TellStick Classic, OpenNetHomeServer running in a RPi) and it is working fine, I can also confirm that OpenNetHome receives NexaFire signals from my Nexa smoke detectors
Best regards, Walter

Cool, thanks for answers.
Then I only need to get some time over to build one
