RE: [weewx-user] Re: No data being recieved by weewx from WMR-918

[Keith Baddock]

I have added the “baudrate” : 9600  to the driver (as looking at the embedded docs in there, which sent me to a link confirming it is 9600 baud) I think this (if it is correct) should be hardcoded rather than configurable as it seems the wmr9x8 will always be 9600 baud, though if this is the default pyserial rate anyway, nothing should need to change!   Debugging:   Stopped the service. Then ran sudo python3 /usr/share/weewx/weewxd /etc/weewx/weewx.conf  to run from the command line.   Should I be seeing anything in the console at all?  Syslog last line indicates  weewx[34003] INFO weewx.engine: Starting main packet loop.   So I think it is listening, but not getting anything so looking like a hardware or configuration issue with the serial port on the PC.  And just when I thought I had “upgraded” my PC with RS232 😉     I let it run for 15 minutes, then cancelled, with no loop packets received.   I will experiment further with the hardware side – maybe something in BIOS configures the port in some way.   Thanks for the help – will let you know how I go, could help some future me!   Keith   Sent from Mail for Windows   From: Tom Keffer Sent: Sunday, 24 July 2022 7:47 AM To: weewx-user Subject: Re: [weewx-user] Re: No data being recieved by weewx from WMR-918   Unfortunately, the driver does not let you set the baudrate from the configuration file. If you want to change it, you'll have to go into the code. If you want to do this, starting at line 94 of weewx/driver/wmr9x8.py you'll find this:           self.serialconfig = {             "bytesize": serial.EIGHTBITS,             "parity": serial.PARITY_NONE,             "stopbits": serial.STOPBITS_ONE,             "timeout": None,             "rtscts": 1         }   Just add baudrate so it looks like this:           self.serialconfig = {             "bytesize": serial.EIGHTBITS,             "parity": serial.PARITY_NONE,             "stopbits": serial.STOPBITS_ONE,             "timeout": None,             "rtscts": 1,             "baudrate" : 4800         }   If that works for you, I'll add the ability to change baudrate through weewx.conf.   -tk   On Sat, Jul 23, 2022 at 2:37 PM Keith Baddock <keithbadd...@gmail.com> wrote: I'll have to investigate how to set the baud rate, as I'm pretty sure the wmr918 is outputting at 9600. It just appears I might not be listening at 9600! I did think that the 11.5k baud was the max the interface could support, but the client software could set it to whatever it needed to suit the device. Running from the command line gives me no visual output. I was expecting to see loop packets too.     Sent from my Galaxy-Tab A 2017 on the Telstra Mobile Network Get Outlook for Android From: weewx-user@googlegroups.com <weewx-user@googlegroups.com> on behalf of Tom Keffer <tkef...@gmail.com> Sent: Sunday, July 24, 2022 12:21:45 AM To: weewx-user <weewx-user@googlegroups.com> Subject: Re: [weewx-user] Re: No data being recieved by weewx from WMR-918   Could definitely be a baud rate issue. The driver opens the port using the default pyserial rate, which is 9600, and you seem to be at 115200.    Can you change the port rate to 9600? If not, we can try changing the driver to expect 115200.   These things are also easier to diagnose by running weewxd from the command line. Then you can see the LOOP packets coming in.   -tk   On Sat, Jul 23, 2022 at 4:27 AM Keith <keithbadd...@gmail.com> wrote: Jul 23 20:33:14 dragon systemd[1]: Started Run anacron jobs.
