My HGI80 equivalent Domoticz setup without HGI80

[bruce_miranda]

We've got plenty of those. Currently the evofw3 is to be considered to be in debug mode. So don't be too alarmed by the error messages. It picks up a lot more than any of it's predecessors, so train your eye to look past the errors, while we continue to work on the firmware.

I acquired an RFBee + UARTBee configured to run this in February.
I installed it on my Windows 10 machine and it has been running perfectly since.
Earlier this month I decided that I wanted to move it to a Raspberry Pi and bought a Pi 4 model B 2Gb.
I have installed Raspian and Domoticz on it. It’s working fine. However, when I add the RFBee + UARTBee combination, It fails to work.

I am presented with 4 serial port options:
/dev/ttyUSB0
/dev/serial1
/dev/ttyAMA0
/dev/serial/by-id/usb-FTDI_FT232R-USB_UART_A800F23V-if00-port0
And three speeds:
38400, 76800 and 115200.

The ports Serial1 and ttyAMA0 both fail to open at any Baud rate.

2020-05-19 09:58:17.958 Error: ASyncSerial: Error setting options!

The ports /dev/ttyUSB0 and /dev/serial/by-id/usb-FTDI_FT232R-USB_UART_A800F23V-if00-port0
both report the same errors at 76800 and 115200. However, at 38400 they both report opening. Eventually, sometimes after an hour or two, the following messages appear in the log:

Can anyone tell me what I have done wrong or is the Pi 4 not happy with an RFBee + UARTBee?

[bruce_miranda]

You should be using Baud 76800, that is the issue.

If its working on Windows, it should work on any OS. The RFBee is just a serial device and is OS independent.
Close Domoticz down completely and make sure that your OS can actually read anything from that serial port directly using screen or another terminal viewer.
Unplug RFBee and look for /dev/tty* devices. Then plug it in and look again. What is your RFBee device called? Is it USB0?
Then try the command "screen /dev/ttyUSB0 76800"

[bruce_miranda]

That normally means the baud rate is wrong. What baud rate were you using on Windows where this was working?

[didsbury]

78600 as recommended

[bruce_miranda]

There is something strange either with your serial driver or the configuration. The RFBee doesn't care what OS its connected too.

[didsbury]

I think I will flatten the Pi and start from scratch again.


Is there anyone using RFBee + UARTBee with a different low power computer?

[bruce_miranda]

A lot of us have used that with the Pi.

[didsbury]

Oh well, I'm currently reinstalling raspbian and then I'll see how that goes.
