Sunrise and Sunset Epochs in MQTT

[Kevin Davis]

What do the epoch times in the sunrise and sunset MQTT topics represent?  Based on my latest MQTT record, neither reconcile with the times shown on the web page for sunrise and sunset?

And as an aside, if I look at my webpage mid-day, does the sunrise time shown reflect the sunrise for earlier that day, or do sunrise and sunset times always show the next time for those events?

Thanks for any help!

Hi,

Without knowing any details of your station or its config or you WeeWX config the best we can say it is should be a Unix epoch timestamp for your local sunrise and sunset time. A couple of generic troubleshooting tips; if the times are wildly in accurate then the likely culprit is an incorrect latitude or longitude setting. That setting could be in WeeWX or could be in your station hardware, again without knowing any details its impossible to say. Things to watch out for are negative and positive lat/long values, there is no standard that everyone follows. Secondly, if your times are say multiples of one hour or maybe 30 minutes out then you likely have a time setting problem somewhere; again without details its impossible to say where.

To answer your second question it depends; however, if you are using the WeeWX Seasons skin or Standard skin then the sunrise/sunset times are for the current day.

The times I see in the standard skin seem to be very accurate.  The values I pull from my MQTT records never match the standard skin values; that's my main confusion.

Ok, how are the MQTT records concerned being produced? Presumably using the WeeWX MQTT uploader or maybe something else?

Might help to get some config details, eg what station, what version of WeeWX, how is the MQTT uploader configured. Probably easiest to post a wee_debug report. If posting the wee_debug report do check the report content for sensitive data such as usernames, passwords, addresses etc before posting. wee_debug does a good job at obfuscating such data but it’s not perfect.
