Exactly what I was looking for. I can send UDP packets to simulate the WeatherFlow device and use the existing driver. The WF API documentation is perfect .. I will duplicate that in my controller. Thanks Vince. Craig On Monday, April 24, 2023 at 4:03:47 AM UTC+12 vince wrote: > You didn't s

You didn't say which os you're using, but one option would be to generate the same input that other drivers already use, and simply reuse an existing weewx driver designed for a different vendor. For example - the WeatherFlow UDP driver listens for broadcasts that meet the published WeatherFlow

Once a second seems more than enough.  Even the venerable Davis Loop is every two seconds.  I don't know how quickly things need to be read during a heavy rainstorm, but I would think that the hardware would be keeping track of tips, if using a tipper mechanism. I only look at the Currrent va

I, too, need to follow Vince's advice as I'm looking for any leads. One thing you asked about is getting info from a file, and I looked at a routine called FileParser (I think) that was associated with a search on github and weewx. If I recall, it pulled in things from a file, parsed the reco

I update about every 15 seconds. The one second was to shorten the time between when the data file is updated and when weewx reads it. But I will look at the intake-strategies document and see what is available. On Sunday, April 23, 2023 at 2:39:31 PM UTC+12 vince wrote: > Start with https:/

Start with https://github.com/weewx/weewx/wiki/intake-strategies but short answer is sure. If you can get the data in any format it is possible to get it into weewx via a variety of methods. You might also poke around https://github.com/weewx/weewx/wiki#extensions-to-weewx for too many examp

By any chance can weewx read from a data file? I could write the incoming real time data to the file as a one line record and then weewx would read this, say once a second or so. On Sunday, April 23, 2023 at 1:56:52 PM UTC+12 DR wrote: > Craig, I don't know of a driver for the Campbell datalo

Craig, I don't know of a driver for the Campbell dataloggers. I wish there were one, I have a very dependable station (CR3000) that I'd like to interface.  Right now it is filling the native tables, and a Weather Display driver using pakbus is pulling those values from that table and handing

I don't know the answer to the primary question. As to recommended protocols, I'd choose MQTT. On Sat, Apr 22, 2023 at 5:53 PM Craig Young wrote: > Is there a driver for the CR300 data logger? If not, I have a PC > connected to the data logger, collecting the live data stream which I can > ref
