i just wanted to say Thank You '[email protected]' for starting this
thread and vince for getting it rolling. I'm an aged 50+ closet nerd with
great google skills and who learned B.A.S.I.C on an Atari...
Here's what they said in the above messages in a way that worked for me.
Maybe next i'll use TxBattery... instead of OutTempBattery, and maybe a
pretty graph.
not sure how to implement that test for null... might look into that more
as well.
To show tempest voltage and current low battery mode in seasons skin...
in 'etc/weewx/skins/Seasons/sensors.inc' change the #def get_battery
_status($x) definition to read as follows:
#def get_battery_status($x)
#set $y = "{:.2f}".format($x)
#if $x >= 2.455
<span class="status_ok">OK - $y</span>
#else
#if $x >= 2.41
<span class="status_ok">LOW - Mode1 - $y</span>
#else
#if $x >= 2.39
<span class="status_ok">LOW - Mode2 - $y</span>
#else
<span class="status_ok">LOW - Mode3 - $y</span>
#end if
#end if
#end if
#end def
