PiSerialGateway and Domoticz

[Fat Fly]

Try with 10µF capacitor. 470 is too big .

[raptorjr]

Thank you. Bought some 10µF.

But I don't see any change in the output from the sensor or the gateway. Have been waiting 5-10 minutes, but nothing appears in Domoticz. Is there anything I can do to try to find the problem? I seem to get the output described on other webpages for working sensor/gateway. But they don't seem to connect.

And how do I get the log function to work? The few times when a log is created I only see some startup message. Nothing about the communication going on. I have to start PiSerialGateway manually to see any communication output. Or isn't that possible to see in the log file?

Here is the sensorsketch, if I have forgotten something. Works fine with plain USB connection to my Pi.

Connect gateway to comp usb and check what happening with arduino ide serial monitor.

[raptorjr]

@Fat-Fly
I don't really understand. The gateway is on a Raspberry Pi, and I have a piece of what is happening in my first post. The output from PiSerialGateway. Otherwise you have to explain a little more on how I should connect my RPi to USB and what to look for.

[Fat Fly]

Connect arduino with nrf to comp. Not raspberry. And check serial monitor.

[raptorjr]

@Fat-Fly

But the NRF is connected directly to the Raspberry. There is no Arduino on the gateway. And the output from my node (Arduino and NRF) with sensors is also shown in my first post.

I'm really lost on what you want me to test.

[Fat Fly]

Okay. With mysensors 2.0 not working nrf directly. Use 1.5 library.

[raptorjr]

@Fat-Fly

Really? They removed that or is it a bug? Didn't think that 2.0 would be a problem. But could test, but sad to not be able to use the latest version.

[mfalkvidd]

@raptorjr this thread discusses an alternative implementation of the Raspberry Pi gateway, compatible with MySensors 2.0.

[Fat Fly]

2.0 is compatible connect nrf directly to raspberry? I do not know and not read this. Maybe i sleep this moment when somebody writing from this. :)

[raptorjr]

@mfalkvidd

Thank you, will check it out. Would be sad to leave 2.0. It seems to be a big step forward in the development.

[Fat Fly]

:D :) :-)

[raptorjr]

It works =)

[Fat Fly]

Beer from you.
