Different Rain Values if It Rains between 23:55 and 00:00

[roe-dl]

Describe the bug
If it rains between 23:55 and 00:00, the rain value displayed in the station observation section is different from the rain value displayed in snapshots section of the home page.

I did some debugging and found that hint in the WeeWX comments regarding dayRain:

                # NB: The WU considers the archive with time stamp 00:00
                # (midnight) as (wrongly) belonging to the current day
                # (instead of the previous day). But, it's their site,
                # so we'll do it their way.  That means the SELECT statement
                # is inclusive on both time ends:

So dayRain (which is sent by MQTT) is calculated different than $day.rain.sum:

• dayRain: 23:55:01 up to now
• $day.rain.sum: 00:00:01 up to now

The correct value is the latter.

Version of the skin you're using
1.2

To Reproduce
You need to wait for a day when it rains between 23:55:01 and 00:00:00. Then you see the problem without further action.

Expected behavior
The daily rain is to be calculated for the time range from 00:00:01 up to now.

Additional context
I guess the solution involves introducing a second observation type for daily rain. That could be implemented by an XType extension. Such an XType extension value would be included in the MQTT output automatically.

HELP WANTED
I could try to write a fix for that, but I would do so on request only, as it is some work to do.

The problem still persists. And I think the reason is in the special behavior of dayRain. What do you think?

[roe-dl]

It is still open.

The PR I issued to weewx-mqtt is still not recognized by Matthew. So this is still actual.

Matthew is not sure he will include the PR into the MQTT extension. If not, a solution inside the Belchertown skin is required.
