Dear Pimatic Community
I stumbled over Pimatic cause I wanted an easy way to use Dashbuttons to control my Sonos Players. Now I am trying to expand the capabilities by using it to control my REV 8342 Outlets which should be running 433mhz.
I have a problem which I am hoping someone could help me with. I am a newbie and I have no Linux Background so please consider this when replying 
I have a Raspberry Pi 2 Model B V1.1 with freshly installed Raspian.
Installation of Pimatic following the Guide works fine, only I am receiving one Error Message: error [pimatic]: Error on incoming http request to /socket.io/: Can’t set headers after they are sent.
Here is what I have done so far
-
I have purchased the recommended RF Set: 433Mhz Superheterodyne 3400 RF via ebay from a Chinese Dealer Gevia ebay
-
I have installed the components according to this guide here, (Option 2 without Arduino to my Raspberry P2 Model B V1.1):
https://forum.pimatic.org/topic/202/4-homeduino-433-mhz-sending-receiving-and-even-more/2
-
I have installed the Homeduino Plugin from the GUI
-
I have made the following settings in the Plugin:
“driver”: “gpio”,
“driverOptions”: {},
“enableReceiving”: true,
“transmitterPin”: 1,
“debug”: true,
“plugin”: “homeduino”,
“active”: true,
“receiverPin”: 0,
“rfrepeats”: 7
} -
Now I would like to check the RF Codes that are sent by my existing Remote Controls (tried 2 different ones, REV and Jarodo) following the next step of the guide here:
https://forum.pimatic.org/topic/210/5-homeduino-and-rf-devices-433-mhz-transmitting-receiving
Problem is that there is no Debug messages showing any received data in the Message Area although I am holding the Remote directly next to the Receiver.
For pimatic-homeduino are there is just:
info [pimatic-homeduino]: Connected to homeduino device.
and an occasional
debug [pimatic-homeduino]: PING
“sudo gpio readall” shows the following so everything seems ok.

I am quite lost since there is no LED on the RF Receiver I cannot even judge if it works at all or if it is running the proper frequency.
Any help with step by step guides would be highly appreciated.
