Installing multiple weewx instances with weewx 4

[Gert Andersen]

Hi

I would like to know if there are some who have been successful in installing multiple weewx instances on the same computer and with weewx 4. First I tried with weewx-multi which I could not get to work. I have also tried 2 startup scripts where I have changed names so the weewx startup script points to its own .conf file. These 2 scripts are based on the startup script that comes with weewx4.

I also asked a question about weewx-multi here, but it's a very old thread not using weewx 4

System Ubuntu 20.04, weewx installed with apt(not install.py)

Before I go any further, it would be nice to know if this is possible. If anyone has multiple instances running using weewx 4, it would also be nice to know which method is used, weewx-multi or separate startup scripts

Thanks for your advice.

Gert

I got two stations, a Vantage and a WeatherFlow, running under 3.9.x using information at https://github.com/weewx/weewx/wiki/weewx-multi.

Unfortunately I’m in the middle of implementing weewx 4 with python3 and the WeatherFlow driver doesn’t work with python3, so I’m done to one station.  But it just occurred to me that I could run a second Vantage!  I’ll try that tomorrow and get back to you.

Regards,

Garry Lockyer

i use weewx V4.0.0. multi as described here (https://github.com/weewx/weewx/wiki/weewx-multi) without any problems. installation type: setup.py

What exactly does not work?

Hi Michael

Sounds good it's possible. 

My installation is not based install.py and maybe that was the problem. Even if I changed the pointers to my installation, weewx-multi could not be started. Maybe I should try install.py.

Could you please post your files you use with weewx 4(weewx-multi used in init.d and weewx-mulite used in default)

Thanks a lot for looking

Hi Gert,

I don't think it has anything to do with the installation method.
My installation of weewx is in /home/weewx
And in this directory are also both .conf files.

Multiple instances working well for me with WeeWX4.0.0 Python3.7 following the wiki instructions. I'm am using Debian10 (Raspbian) on a RaspberryPi4

I have tried it with setup.py and Deb package and both work fine using the multi startup script. Currently running three instances with setup.py install

Hi 

I have just installed using install.py and using the files from Michael and now it's working. 

Next step to use mqtt and Belchertown for 3 instances. 

Thanks for your help.

I run 3 instances of weewx V4 on one machine, all using the same code base, but different versions of weewx.conf. It should not be a problem.

It also doesn't matter how you install the code base. The key is weewx.conf. It contains the information on where each instance is to find its drivers, skins, database, etc.
