Band pass-filter (new version)
#11
My Telldus system is still better at receiving, but pilight is doing a great job! I don't believe that the reason for the Telldus to perform better is software related. It either has a better receiver or antenna.

For the pilight I have a simple curled up wire as antenna, which probably isn't the best in the first place. Also I have no idea what receiver the Telldus uses. The pilight setup is doing a hell of a job and soon I will integrate pilight in my custom home automation software.

To give a concrete example: The Telldus and pilight are roughly in the same place of my living room. When I sit at the other side of the room and block the signal using my own body Telldus still does a better job. But when I don't block the signal with my body pilight works excellent.

This is something for the future though. In principle I notice pilight is working excellent with the new filter. And only 1% of CPU usage :-) Things are looking good!

Cheers for all your excellent work!

So is this with the same receiver? What is that Telldus? I don't know that one.

I'm also still looking for better reception and the best antenna/receiver combo...

I just received the new lpf. After wiring it up on a breadboard, pilight did no longer receive anything. pilight raw shows an endless stream of noise. Is there any way to check if the firmware and the microcontroller is ok? I am back to the old lpf for now. @curlymo: I hope you can help

Can you check your CPU usage when the BPF is connected and pilight-raw running. It shouldn't be more than 5%
Code:
PID   USER      PR  NI  VIRT  RES  SHR S  %CPU %MEM    TIME+  COMMAND
2898  root      20   0  9716 3188 2540 S   1.0  0.8   0:02.76 sshd
14731 root     -56   0 19620 1340  872 S   1.0  0.3   0:00.15 pilight-raw

Anyone tried to program the firmware on a ATTiny84 with Arduino IDE/compiler (on windows)?
I copied the code, but a testcompile is showing errors: "'TCCR1' was not declared in this scope"

The included AVR libs are on my system

I don't think the arduino will work. Why don't you just flash it with your Raspberry Pi?

Grabbing the USB programmer was easier than hooking up wires from the pi-plate Wink

There is not more than 5% CPU-load but the problem is that when I connect the new filter I get a constant stream of data from the filter. If I connect a LED to the output of the filter it is flickering like crazy. pilight fails to receive any command from my intertechno-remote with the BPF. Do I have to change anything in the config? I am using 433gpio.

Edit: Even if I only connect a jumper-cable to the input of the filter it is producing a lot of noise.

The filter doesn't remove all noise so it supports impuls as the most difficult protocol. If only arctech switches are used the noise could be removed with a little adjustment, however the current noise is too low to be a problem. So the filter is programmed with as much compatibility as possible.

I tested all filters myself before shipment so I know they work. Please check your connections again.

@curlymo: After reconnecting everything again I wanted to report again. The filter works. CPU usage is around 1%. Still if I run pilight-raw I get a nonstop flow of readings. Is this normal? With the old lpf I had nearly no noise at all.
