Good to see it is working Steve.

Unfortunately there is not much you can do. A similar issue arises if a
sensor drops for some reason. The SteelSeries code is such that it takes
the value for a given observation and tries to interpret it as a number, if
it can then the number is displayed in the selected units, if it can't be
converted to a number then 0 is displayed. There is no ability to display
anything other than a number on the gauge LCD and the pointer just reflects
what is on the LCD (or is it vice versa?). I guess you could say that I
have contributed a little to the issue as rtgd.py will set a field to 0 in
the applicable Metric units if the observation in non-numeric or undefined
(or None in python parlance). So for temperature type fields that have a
misisng or undefined value, 0C or 32F will be displayed. Why? I guess
because I use Metric and I find that if a field is missing data displaying
a 0 is better than a display of 32. I could probably make the units in such
a case user selectable, so folks that display F will see 0F rather than
32F. UInfortunately not much else that can be done short of modifying the
SteelSeries code and I won't be embarking on that.

By all means, I will update the wiki on the realtime_gauge-data GitHub site
and referece it on the weeWX wiki, but that will be a work in progress for
a little while.
As a final thought a couple of things you might want to consider doing to
fine tune your SteelSeries setup.
1. gauge-data.txt units. A default install of the realtime_gauge-data
extension will result in gauge-data.txt containing Metric units. Whilst the
SteelSeries Gauges page gives you the ability to change display units
dynamically, anyone going to your page the first time will see the units
used in gauge-data.txt. (as an aside the SteelSeries gauges stores a cookie
that keeps your display units settings for subsequent page visits). Given
you are in the US you might want to switch your gauge-data.txt units to US
customary so that visitors will see US customary by default (I expect most
of your visitors are US based). To do this you need to edit the
[RealtimeGaugeData] [[Groups]] config options in weewx.conf. Just change
the options to the units desired, the unit codes are the same as used in
weeWX skins ie degree_C, degree_F etc. Be aware that the SteelSeries Gauges
do not support all units that weeWX does (eg mmHg).
2. Mouseover plots. Given the changes made the mouseover plots are broken,
I suspect a chnage is requried to gauges.js, the plots are still in
Weather/ss on your web server but they are not being updated (refer point 3
below). Try changing the following line (line 38) to read:
imgPathURL : '../ss/', // *** Change this to
the relative path for your 'Trend' graph images
3. Disabling the [[SteelSeries]] skin was done as an easy way to prevent
there being conflicting gauge-data.txt files on your web server. There are
a few side issues to disabling the skin. One is that the ss/index.html file
is no longer generated each report cycle, this means that things like weeWX
version etc will never update on this page is you happen to upgrade weeWX.
Another is that the mouseover plots for the gauges are not generated so
your mouseover plots are empty. So you probably should re-enable the
SteelSeries skin but disable couple of its features. I suggest you:
a. edit weewx.conf and remove the comments against the [[SteelSeries]] skin
b. edit skins/ss/skin.conf, locate [CheetahGenerator] and disable the
generation of gauge-data.txt eg:
[CheetahGenerator]
encoding = html_entities
[[ToDate]]
[[[index]]]
template = index.html.tmpl
#[[[data]]]
# template = gauge-data.txt.tmpl
c. edit skins/ss/scripts/gauges.js and make the same changes to it that you
made to gauges.js on your web server. We do this as once the skin is
enabled again any restart of weeWX would see the gauges.js on your web
server overwritten.
d. stop then start weeWX
e. check that it all still works!
