Have a look in that file for the units that mesowx knows about and use
those. If what you want is missing from there then it gets complicated as
you'll need to add them and mesowx is sulky silent when reporting error
messages. That is, you'll most likely be met with nothing but a blank
screen in your browser if you get something wrong.
The only workaround to the silent treatment (for me anyway) is to make
small changes, ones that are easily reversed when experimenting. When you
get a working version save it as a milestone, you'll probably need to
revert to it at some point.

I'd be careful of changing indents within these files, they can be extra
sensitive to changes in whitespace (and commas, and colns, and...). What
follows appears to have an extra tab spacing - I'd remove that and continue
as the original has it formatted.

The units you've added above; do they tally with how weewx describes them?
Have a look within the file weewx/units.py where you'll find, for example...
obs_group_dict = ListOfDicts(
[...]
"soilMoist1" : "group_moisture",
[...]
which leads to...
MetricUnits = ListOfDicts({
[...]
"group_moisture" : "centibar",
[...]
Not percent as you have it described above
"soilMoist1" : {"unit" : "perc"}
Similarily with...
"heatingVoltage" : "group_volt",
leads to...
"group_volt" : "volt",
again, not perc(ent)
As a working example, I had to add "volt" to my Mesowx installation.
I did that within js/mesowx.js by adding that unit , as follows...
mesowx.Unit = (function() {
var Unit = {
[...]
volt : new meso.UnitDef("volt", 'V') // volt
};
Also adding to include/Unit.class.php (and note the comment, it meant
something to me at the time :-)
class Unit {
[...]
const volt = "volt"; // volt - not registering??
}
Doing the above I'm able to use volt within js/Config.js without getting
errors in the browser output... or at least the silent treatment. (And
ignore my database field names - I co-opted those fields and never went
back and created new, specific - ie: nonconfusing - fields)
js/Config.js
Config.fieldDefaults = {
[...]
'inTempBatteryStatus': new meso.FieldDef('inTempBatteryStatus',
mesowx.Unit.volt, 2, meso.Agg.avg, 'InHumidity voltage'),
'outTempBatteryStatus': new meso.FieldDef('outTempBatteryStatus',
mesowx.Unit.volt, 2, meso.Agg.avg, 'outHumidity voltage'),
'windBatteryStatus': new meso.FieldDef('windBatteryStatus',
mesowx.Unit.volt, 2, meso.Agg.avg, 'Vane voltage'),
'rainBatteryStatus': new meso.FieldDef('rainBatteryStatus',
mesowx.Unit.volt, 2, meso.Agg.avg, 'Barometer voltage')
};
also within include/config.json
"columns" : {
[...]
"inTempBatteryStatus" : {"unit" : "volt"},
"outTempBatteryStatus" : {"unit" : "volt"},
"rainBatteryStatus" : {"unit" : "volt"},
"windBatteryStatus" : {"unit" : "volt"}
},
To recap. With mesowx, make small changes at a time. Once you get the hang
of its quirks perhaps you'll be able to wade in and do them all as a batch
but do start small.
