upgrade from 3.3c to 4.3

[giantmr4]

i miss several updates for my meteohub in the past few months.

currently my meteohub is using version 3.3c.

can i simply update it directly to 4.3?

any special care or attention during such update? (i just know in version 4.x, a number of new features are introduced, for example, multi-stations, system graphs, ...)

only 1 weather station console is currently plugged to my meteohub.

thx. :)

Yes, according to the download documentation, you can upgrade directly to version 4.3 from version 3.3c:

Applicable to versions:
* Meteohub V3.1 - 4.2h

Once you have updated, you will need to go to the "Weather Station" page and update your station settings to work with the new version 4.x configuration. (You can also assign "Weather Station 1" as system data, which will give you information about Meteohub system load, uptime, etc., but that is optional.)

you are correct.

i am required to manually,

- add a new weather station and assign a name, attitude value, etc to the weather station.
- re-assign the sensor id of the top list and clear the bottom list to be evaluated in the sensor webpage

after all the setting is completed, the meteohub starts data re-computation. however, i find it takes very long, longer than the last update. is it normal?

from version 3.3b to 3.3c:

from version 3.3c to 4.3:

Note: very strange that the data recomputation takes twice itself. :dry:

That can easily happen.

Certain actions in Meteohub flag it to do a recomputation. While setting up and tweaking settings it is very easy (pretty much inevitable) that you will trip the flag for recomputation several times. Each trip of the flag is independent (i.e. a new 'trip' doesn't cancel ones already in progress or waiting), so it's quite possible to cause multiple recomputation.

In the early days of v4, while setting up and testing out the weather stations feature (trying out 3-4 stations at the same time) I think I recall queuing up more than 10 recomputations at one point! :laugh:

If you are interested in relative speeds of recomputation for different setups you might be interested to look through this thread.
