Re: [weewx-user] safety of wind instruments on metal pole on roof?

What about using a fiberglass pole instead? The wires to the instruments could still potentially attract lightning, but probably wouldn’t carry enough current to start a fire — might blow out the weather station electronics, but not burn down the house. Max-gain Systems

Re: [weewx-user] When did the blast wave of the eruption "hit" your station?

First, not starting any arguments. Second the chart is over a 48 Hr period, sample at 5 minutes intervals. Both my stations had basically shown the same increase and decrease for each wave. And according to the following link: https://twitter.com/akrherz/status/1482436390105272320, the direct

Re: [weewx-user] When did the blast wave of the eruption "hit" your station?

I think you’re looking at the wrong time period.  The initial, direct wave arrived at the U.S. west coast — about 8400 Km from Tonga — around 4:00am Pacific time on Jan 15.  It should take 3-1/2 to 4 hours to travel the additional 4600 Km to your location.  That, plus the 4 hour time difference,

Check early morning Jan 16, when the wave came the opposite direction. Might of capture that wave. They say the second wave was stronger on the east coast. [image: Eruption Pressure Blips.png] On Monday, January 17, 2022 at 10:24:20 PM UTC-5 robcr...@gmail.com wrote: > [image:

Thanks Gary, I appreciate it. Hopefully UPDATE won't raise any serious weewx issues. I look forward to seeing it raised as an issue :) On 18/01/2022, gjr80 wrote: > Correct, wee_import will not accept text only fields. When we put together > wee_import we only included support for numeric

[weewx-user] Re: Storing Text as a record, wee_import and mysql UPDATE

Correct, wee_import will not accept text only fields. When we put together wee_import we only included support for numeric fields; text fields were omitted, perhaps not intentionally, but more likely because no real consideration had been given to including them in the schema. That being said,

[weewx-user] Re: safety of wind instruments on metal pole on roof?

There are people who lost their electronic equipment in the house including radio, tv set etc. because of a little bit of lightning near their house. Trees are not exactly lightning rods. I would strongly suggest to ground the pole using a round steel of about 1/3" (about 10mm). There should

[weewx-user] safety of wind instruments on metal pole on roof?

Not strictly weewx related, but: Any safety concerns with mounting my wind speed and direction instruments on a 1.25" galvanized steel pole, 6 feet above the roof line? I currently have a prototype anemometer about 20 feet in the air. It's well away from our house so solar powered, which is

Re: [weewx-user] When did the blast wave of the eruption "hit" your station?

Not sure I am really seeing it here in maritime Canada. We're about 13000 km from Tonga. Attached is a gnuplot command file and its output is: [image: barometer.png] The pressure pulse should have arrived about 12:00 local time. There is a little pressure increase at about 12:10. Use the

Re: [weewx-user] How to extract graphs from a specific date?

You can give the utility wee_reports with a timestamp. For example, graphs of 2022-01-01 UTC would be *wee_reports /etc/weewx/weewx.conf 1640998800* Because the timestamp is a positional argument normally found in the 2nd position,

[weewx-user] How to extract graphs from a specific date?

Good afternoon, I would like to extract the mini graphs for a specific date e.g. for 2022-01-01, so that i can see e.g. the barometer curve for that day from 00:00 to 23:55 and the graph is named and saved with the corresponding time stamp e.g. barometer_2022-01-01. Is that possible with

[weewx-user] Storing Text as a record, wee_import and mysql UPDATE

Working with TEXT records. I've gone through the wiki entry https://github.com/weewx/weewx/wiki/Storing-text-in-the-database and that all works well. I can add TEXT to the database and display it in the weewx skin. So far so good. Using a modified filepile.py, I can add what I want via the
