It's not necessary. Regardless, you 'can' do this if you fork the driver and edit judiciously. I successfully started two Simulator instances with one renamed to 'Simulator2' driver type, but I needed to copy the existing simulator.py driver to simulator2.py 'and' edit its DRIVER_NAME to match. root@buster:/home/weewx# ls LICENSE.txt README.md Simulator1.conf Simulator2.conf archive bin docs examples skins util weewx.conf weewx.conf.4.5.1 root@buster:/home/weewx# diff Simulator* 48c48 < station_type = Simulator --- > station_type = Simulator2 62c62 < [Simulator] --- > [Simulator2] 79c79 < driver = weewx.drivers.simulator --- > driver = weewx.drivers.simulator2 572c572 < database_name = weewx-Simulator1.sdb --- > database_name = weewx-Simulator2.sdb Note - that required me to copy the original driver to another name and edit lightly for consistency. root@buster:/home/weewx/bin/weewx/drivers# ls __init__.py __pycache__ acurite.py cc3000.py fousb.py simulator.py simulator2.py te923.py ultimeter.py vantage.py wmr100.py wmr300.py wmr9x8.py ws1.py ws23xx.py ws28xx.py root@buster:/home/weewx/bin/weewx/drivers# diff sim* 18c18 < DRIVER_NAME = 'Simulator' --- > DRIVER_NAME = 'Simulator2' For my original scenario (one interceptor, one GW1000) this all works now - > after divination between the WiKi lines ... > > A wiki is a 'shared' editing environment. If you have changes that you think will make the wiki better, please write them up and submit them.

For example, the WeathflowUDP driver defaults to 'not' sharing its listening socket with other programs on the same computer, but it can be configured to share the socket if you edit the driver stanza in the config file. It's possible gw1000 is similar and that you can run only one instance on the host computer (I didn't have time to test this).

You can run two of the same, or two different, as long as you're consistent in your naming 'and' as long as the driver supports multiple instances of things on the same port if it's a network-based driver like WeatherFlowUDP and gw1000 are. -- You received this message because you are subscribed to the Google Groups "weewx-user" group.
