We have a tiny sensor/discovery module (gist below) that picks up the (back)pressure, in Bar, of a cooling system.
However when we add below to config.php:
$config['sensor_types']['pressure']['symbol']='B'; $config['sensor_types']['pressure']['text']='Pressure'; $config['sensor_types']['pressure']['icon']=‘oicon-omega’;
it seems that these values are wiped/overwritten by the values from definitions.dat.
What, or perhaps, where, is the proper way to add these ?
Thanks,
Dw.
