Rapid Fire update rate

[Roger Lee]

How do I change the rapid fire update rate to WU? I would like to update once every 30 seconds.

No easy way to do it. You'd have to subclass class StdWunderground, then override method new_loop_packet() to filter the LOOP packets down to what you want.

Have to ask: the whole point of RF is to give realtime displays on the WU. What's the point of posting less often?

"rtfreq

When rapidfire is set, the rtfreq parameter is sent, and should correspond to "the frequency of updates in seconds". Optional. Default is 2.5"

That does not seem to do anything. Just trying to reduce the bandwidth to WU.  There are few, if any, weather parameters that change fast enough that I need to see values faster than, say, 30 seconds.

What station are you using? If enabled rapid fire updates are sent on receipt of every loop packet, so for Davis stations it’s every 2.5 odd seconds, for other stations it’s different and for some stations that send loop packets at different intervals it’s variable. So you might not be using as much bandwidth as you think.

The rtfreq config option is a bit of window dressing really; all it does is set the value of the rtfreq parameter in the rapid fire data string that is sent or WU. What WU does with it nobody knows, but as far as WeeWX is concerned it’s just a fixed number sent to WU in every rapid fire packet.

Davis Vantage Vue. I guess I can live with the update rate as long as WU can handle it. Thanks for the information on rtfreq.

Here's an old post that explains rtfreq. https://github.com/weewx/weewx/issues/128#issuecomment-225394020

Something to do with Flash graphics (remember that?!)
