Looks like it has a good antenna.

I already have a gateway with a Trransmitter STX882 and Receiver SRX882, but I can not get the signal from a sensor on the edge of my house.

Is this sensor inplace replacement?

This device is not supported by OMG.

By the way may I advise you 2 things:

  • add good antennas to your transmitter and receiver
  • if it is not enough add a second gateway

with the antennas. I read the suggested post (from some weather portal) related to using other antennas but I do not think it will be easy to attach better antenna to this.

Also for the transmitter I can use 9V for better range right? But the receiver should not use anything over 5V?

I already replaced the wire antenna at the smoke sensor with a spiral one so I can not do more.

STX882 is rated for 6V max, it will not support 9V see details below:

SRX882 is rated for 5V:

Yes I think the antennas could be better, you are using the basics ones. If you know how to solder it can be done easily to add an armed wire and a more performant antenna.
Some infos there

Thanks

Then I will order this too:

Just cut the small connector on the end and solder the outer layer to GND and the core to Antenna pin?

Yes and fix the antenna to a plan base.

Hi there.
I’m using these CC1101, but not with OpenMediaGateway because it’s saddly not supported.
I’m using it with a NodeMCU-Board and a flashed SignalESP, which supports CC1101.
The CC1101 is able to sniff my no-name-weather sensors accross my home… Maybe someone can tell me, how i can use other RF-Receiver with OpenMediaGateway to readout these temperature sensors properly. I had no luck in the past doing that. If that would work, i would replace my SignalESP with an OpenMediaGateway

Hello,

Could you indicate the brand and model of your sensors?

Hi, thanks for reply,
the CC1101 is a TI-CC1101 on in and i bought it here:
https://eckstein-shop.de/Wireless-RF-Transceiver-Module-433Mhz-CC1101-CC1100-Antenna

but i think you propably meant my other current with openmediagateway working sensors:
RBX6 v2 and FS1000A 2008-8…

i know, they are really ugly once and if its a problem i would change them to some better parts if that helps to work.

10

I mean more if you have a link to your no name weather sensors ?

11

its something like IAN279818

It works pretty well with the CC1101 and SignalESP but i can’t capture any data with the RBX-Receiver…
So i tried to get the OpenMQTTGateway-CC1101 samples working, the last one with the lib from LSATAN seems to talk fine with the CC1101 but only captures signals from my RF-Remote :-D,

12

maybe that helps:
the CC1101 receives the following Manchester-code with SignalESP…

MS;P1=-960;P2=490;P3=-1939;P4=-3891;D=24232123212123232323212121212121212323232321212321232323232121212121212121;CP=2;SP=4;R=1;O;m2;

I have read that pilight supports a weatherstation from Lidl (Ninja blocks).
So maybe try the pilight version of OMG?

14

Thanks for the suggestion… i will test it…
I spend the half day on RF-investigation… It seems to be a bit more complex as i thought. SignalESP has a complex class especial for analyzing the received signals…also the receiver has to be set up in a special way, but i couln’t yet figure out how…
so i will try the pilight version later…

15

The OpenMqttGateway Pilight Version with CC1101 works well with the LSatan Lib… But it only captures signals from my switching sockets with the quigg_gt9000 protocol. But no weather signals will be received :frowning:

16

Yeah, the only gateway that recognises my Lidl outdoor sensor is RFLink, OMG RF and Pilight know nothing about it :frowning:

17

And how is it? It’s a directional antenna so you might have hard time getting it in the right position to actually improve the range…

18

Waaay better. I was thinking about adding a second geteway but it works great. I also replaced the spiral wire antenna of the smoke detectors and I have 100% coverage at home (100m^3)

19

Thanks for the info.
Do I get it right that you connected that antenna to your OMG receiver?
And what antenna do you use with your smoke detector now?
