Hi, 1. It appears as if the Zembretti forecast is inserted into the bar at the > top of the page. Is there a way to a: have information from a different > forecast such as WU be placed there instead? or b: Insert other > non-changing text like name of station, etc.? >
Assuming you are using my realtime gauge-data extension there is presently no means to directly display a WU sourced forecast as there is with Zambretti. There is the ability to display static text or text from a file. Have a look at the comments up front of the rtgd.py file (in /home/weewx/bin/user or equivalent). The scroller_text and scroller_file options under the [RealtimGaugeData] stanza are what you want. I think the comments explain their use. 2.

Seriously, the issues will be does it display what you want on the gauges and will it survive an upgrade. Again, assuming you are using the realtime gauge-data extension, the generated gauge-data.txt file uses the heatindex and windchill values provided by weeWX. If these obs are provided by your station, weeWX just pases them through and they are what they are. If your station does not provide them, a default weeWX installation will attempt to add them through the StdWXCalculate service. In terms of heatindex, provided fields outTemp and outHumidity are present the StdWXCalculate service will calculate heatindex. If either of these fields are not present heatindex is set to None. If outTemp < 80F or outHumidity < 40% heatindex is set to outTemp. If you are seeing something different it is likely because your station provides heatindex, the StdWXCalculate service is misbehaving or maybe there is a heatindex correction set in [StdCalibrate] [[Corrections]] in weewx.conf. Similar deal for windchill but the obs required are outTemp and windSpeed, and windchill will track outTemp if outTemp >= 50F or windSpeed <= 3 mph. If neither of these fields are what you want you may be able to make simple changes via a [StdCalibrate] [[Corrections]] entry or perhaps via a simple service for something more complex. I am loathed to alter how the realtime gauge-data extension handles heatindex and windchill, the extension should simply take what is emitted from weeWX. In terms of an "out of range" message, the SteelSeries Weather Gauges will attempt to interpret heatindex and windchill as a number, if it cannot parse them as a number then the gauge will display 0. This behaviour cannot be changed without modifying the SteelSeries Weather Gauges code. This being said, the realtime gauge-data extension will only provide a numeric value for heatindex and windchill (and for all other obs) irrespective of whether weeWX emits a numeric, None or the field is omitted. It is also worth noting that as of weeWX v3.7.0 there has been a conscious effort to remove fields from the weeWX drivers that are not provided directly from the hardware. Another thing I found (which may be of no consequence) is that in gauges.js > for case 6 (weewx) there are some lines about HeatIndex, but at least one > is written as HeatIndx. Does this matter? Or am I just driving myself and > others mad?? > I trust you are referring to this line (it's appears 4 times in the file): // Temperature: dewpnt, apparent, windChill, HeatIndx, humidex This is just a Javascript comment line, it has no effect on the the code.So no need to drive yourself mad, its not worth it. I hope this answers your questions. Gary -- You received this message because you are subscribed to the Google Groups "weewx-user" group.
