When to use a Service vs Driver?

[PeterQuinn925]

I didn't see this in the discussion or docs. I'm trying to decide if I should use a service or driver. I have a driver that I'm using for other data, can I have two drivers? Or, should I use a service to augment the existing driver with additional MQTT data from other sensors?

Yeah, its buried in the readme and could be easier to find. A WeeWX instance can only have one driver. So, if you a running instance that you want to augment, you will need to run as a service.
An alternative is to run multiple instances of WeeWX.
