Based on your requirements, I think you should be setting up the mqtt extension in weewx, and publishing loop packets, at least for wind. I have a Davis Vantage Pro2, and it reports data every 2s. However, not every LOOP packet, as they call them, has every bit of data. I think wind is quite frequent, as your desire for rapid wind information is not unusual. Rain, on the other hand, is less frequent, as the tipping bucket only tips so often. There are many stations to choose from, and acurite is a popular low-cost choice. It seems to be one of the more reliable low-cost stations. Generally, people like the Davis equipment except that they complain about how much it costs, and that you have to have separate data logger, and occasionally slight USB flakiness. But other than that it's great. I am not sure how your wind is and how real time you need, if you set your thresholds right. You'd have to look at high-time-resolution data for your site for a while. Keep in mind that weather standards call for your wind instrument to be 10m above ground in the clear, but that this is often too hard. However, you just need to measure wind so you can infer conditions near the awning and figure out what's too much in your judgement. -- You received this message because you are subscribed to the Google Groups "weewx-user" group.
