I am trying to move my 'workhorse' (it runs weewx, as well as a fair bit of home-brew home monitoring and control software) Raspberry Pi 3B to Trixie, and I must confess that I am getting increasingly frustrated with the problems introduced by Debian's assumption that you should be happy to (essentially) recreate your system configuration from scratch every 2 years for the new release. I do have two 3Bs, so I was able to do much of the recreation on a new copy of Trixie on the 'spare' 3B, but I don't have two RTCs, and I don't have a duplicate of the Meteo-Pi that acts as the serial interface to my Vantage Pro 2. I was fairly easily able to install and run weewx (5.1, now updated to 5.2) under Trixie with its simulator driver, and I am now at the point of trying to move the configured Trixie SD card to the hardware-equipped 3B and to run weewx 'for real'. After a few gotchas, I got the RTC working, and made the appropriate modifications to my existing weewx.conf to conform it to the layout of the Trixie installation. I disabled the Console TTY and enabled the serial interface on the Pi, and pointed weewx (successively) to dev/tty, dev/tty0, and dev/tty1. weewx starts up without errors, but reports that it is getting no response from the serial port, and cycles between the 'no response' and 'retrying' messages. I don't believe that this is, strictly speaking, a weewx problem, but has anyone got weewx working with this or a similar combination of operating system and hardware, and/or got any helpful suggestions?
