[sc.lep...@gmail.com]

Hello

I used the simple template  from https://github.com/matthewwall/weewx-simple

My platform 

Debian10 / Python 3 /last Weewx (4.3.0) 

When I activate simple template  I ve this error  :

not exactly when I activated this extension , but when cheetahgenerator ;)

Would you please share your file /etc/weewx/skins/simple/index.html.tmpl ?
The error log seems to point at an error contained in this file. Something missing or too much or at the wrong place.

Without seeing it, no further conclusion possible.

Thanks and regards

It seems weewx-simple does not (yet) support Python 3.

So it appears - just tested and saw that under Python 2.7.16 the skin runs without problems. Weewx is 4.3.0

I think, if you also install python2 (they can be both on the same machine)
and change in /etc/default/weewx
the WEEWX_PYTHON entry into

WEEWX_PYTHON=python2

and then restart weewx, it should work.

Once the skin has been updated and tested for Python3, you can change it back to python3 again.

No need to make such drastic changes. True it is a python 2/python3 issue but the fix is far simpler. The clue is in the error message:

Jan 24 21:20:16 debian-weewx weewx-WMR200[13641] ERROR weewx.cheetahgenerator: **** Reason: '>' not supported between instances of 'str' and 'int'

An expression involving > in the template is using a string and an integer as operands and python3 doesn’t like the string (whereas python2 will accept a numeric string). Looking through the template there are five instances where > is used in an expression. Three of these use xxxx.raw on the left hand side of the > so they are not using a string. The remaining two are using xxxx.formatted on the left hand side of the > and xxxx.formatted does return a string. So that suggests the following lines are the source of the error:

#if $trend.windSpeed.formatted > 0
&#8679;
#elif $trend.windSpeed.formatted < 0
&#8681;

I can see no reason to use .formatted over .raw in this case so try changing the above lines in /etc/weewx/skins/simple/index.html.tmpl to:

#if $trend.windSpeed.raw > 0
&#8679;
#elif $trend.windSpeed.raw < 0
&#8681;

Save the template and see how that goes on the next report cycle, no need to restart WeeWX.
