Not possible. genLoopPackets() is a generator function. While you can pipeline generator functions together (have one feed into another), you can't have them running in parallel.
The general problem is that WeeWX allows only one driver, and, for better or worse, the trend over the last few years has been for people to use more than one device feeding the WeeWX engine. I've been experimenting with designs that would use a select() function, or Python async functions, to allow multiple devices. Unfortunately, it gets complicated real fast, plus the necessary underlying libraries are not always there. It would also, almost surely, break backwards compatibility. It's a problem better done in JavaScript. On Mon, Feb 15, 2021 at 6:34 AM Pat O'Brien <[email protected]> wrote: > Is it possible for a StdService to submit it's own loop packet?
