Olympia sensors 868mhz (door, pir, glass, water)

[ActionHenk]

Hi,

I have currently a Olympia Protect 9061 system, it uses the 868 mhz band.

I want to integrate the pir sensors and door sensors in domoticz with a rflink 868 mhz, is this possible?

It would be nice since then i don't have to buy and install all new door and pir sensors.

I don't have a rflink yet. But before i buy and build one i want to be shure if my Olympia sensors work with rflink 868mhz on domoticz. If this doesn't work out i see no point to build a 868mhz version. Then it would be better to build a 434mhz rf link and buy all new sensors because i have much more choice.





I have one door sensor open now, but i can't read the discription on the chip, so i don't know what chip it uses.

Please help me, greetings Chris!

I forgot to tell, i have also 2 sirenes for this system that i would like to use with rflink868 on domoticz.

Oke got some more info, all the door contacts and pir sensors have the si4010c2 chip in them.

The si4010c2 chip is actually a all in one: 27-960MHZ rf transmitter with a CIP-51 8051 MCU micro controller in it. The PCB also have 4 headers for programming, rx, tx, gnd and 1 unnamed.
I really hope i can do something with my all my installed sensors and RFLink

I wonder what chip the sounders have, because they of course receive a signal, but also send a battery low message to the base unit. Maybe a combi chip, or both.
But i can't get them now to inspect because they are hanging high on my house outside.


Hope you guys can give me some more info, i will continue to search the web for more info about what rflink supported sensors use.

greetings!

Another reply,

after a lot of searching i find it is possible to hook up a RFLink to a raspberry pi and use a signalrecorder/scanner/sniffer to log the transmitting signal.

I could then resend that signal (clone) and do nothing with it, that would work for switches it seems. But i need door and pir sensors and sirenes, not to turn a switch on.

So, i need to record/scan the signal, encode it and then turn it in to a protocol or a inverted protocol. For that i need an raspberry pi and some plugin. To bad i choose to run domoticz on a synology instead of a raspberry pi.

Can someone help me further? Is it already worth buying and building a RFLink 868 mhz? Or am i better of buying and building a RFLink 434mhz and sell all my sensors and alarm base to get some supported sensors?

I doubt it can be done with any d-i-y solution.
The RF signal itself is probably the easy part. The chip supports FSK and OOK. Finding out what signal it sends a matching receiver or transmitter can be used.

However..... the chip also has AES crypto on board!
It is very likely that communication is encrypted and braking the AES encryption is a whole different ball game.

Oke thank you very much for your answer!

I gived it some time to think what was best for me and since i needed to buy and install all new security sensors anyway and ditch all my excisting sensors i decided to go Z-wave for better protection and feedback on critical stuff that needs it and ordered 8 door sensors, 3 pir sensors and 2 sirenes, all z-wave.

Now i don't need an rflink for now, but in the future i will automate my rolling curtains with tubemotors and i think i will control those with rflink, since i don't see a nice z-wave application for it.

So for the time beeing rflink is on a hold here.

Greetings and thanks again for your help!!

Better make sure that z-wave is what you want for security.. because it has its flaws.
