I've been working on the OCS again over the past couple of weeks and have added more weather sensor support. There is now support for Modern Device's "hot wire" type anemometer. There is now support f

Like OnStep the OCS an Arduino IDE based project, this one runs ONLY on the Arduino Mega2560. This simplifies development and enhances reliability which I rate as being of great importance to this pro

Strange. I looked at the code and nothing jumps out as a cause for this. I will keep an eye out for it.

Sounds normal. As expected. This is a first try at getting it working and I'm new to this also, we need to gather data and figure it out. Well shielded from light my sensor showed expected mpsas value

This is an interesting data point, a full moon lit clear sky comes in at about 15.2 mpsas: https://www.cloudynights.com/topic/623469-sqm-readings-during-full-moon/

Note that includes the brightness of the Moon itself (our sensor is "wide angle" like the SQM not the SQM-L.)

Just updated the OCS to version 1.4d at my observatory. Operating in imperial units there was no "shift" in pressure from the sensor which reads 30.00in. at the moment vs. NWS online area weather site

A nice change in the OCS 1.4d was switching to a more modular structure in the Weather.ino file. Now, each weather sensor type has prototypes for initialization and query functions. This allows the us

Please report how that works... I was afraid of "skewing" the IR sensor. I noticed that too, just didn't get back around to doing something about it. The fix is on GitHub now though.

I'm 3D printing the fixture for my SQM right now. If this works out I'll post the design and stl files. This is for the Adafruit TSL2591 sensor which sets into the four cut-outs. A weak slightly conve

I coded nothing to solve this problem and I've never seen it on my hardware. No reason to believe that. Is sensor data still correct on the "overview" / index page?

I thought the other issue likely had to do with Chart.js This seems different.

Corrupted how? If you have the file please post.

Just a note... if a weather log file does get corrupted there will be a new one tomorrow.

I will take a closer look at this over the weekend. For now, my thoughts are: 1. The chart split with data half gone ~ 17 hours back was due to the prior days data file being ok then the new data file

First off, be sure you are using the latest OCS (from a couple of days ago.) The structure of the Weather.ino file changed.

I put together an OCS w/BME280 this morning; the following code worked for me just copy each sensor type into its respective place in Weather.ino: // --------------------------------------------------

Glad to hear the charts are up and working again. I setup an more complete OCS on the bench this morning. Like I do with OnStep hardware I plan to keep this around for testing/debugging. During setup

I suppose the SD SS on my OCS W5100 probably has a pull-up resistor built in (to disable) so worked fine where this W5100 doesn't.

I didn't try to compile but the bolded line above is supposed to be a comment... ... // return (invalid) if not implemented or if there's an error double weatherSkyTemp() { if (!skyTempGood) return in
