- Battery Percent Item to Thing Link
Profile: JS
Profile Configuration: | (((parseFloat(i) - 3)/0.012) + 0).toFixed(1) + "%"
With this configuration:
- Battery Voltage shows (eg) 3.536 V
- Battery Level shows 44.7 % in Settings → Items and Analyze chart, but 44.7 V in almost all other UI, eg:
- overview UI, Settings → Items → Battery Percent, etc
If I remove “unit: V” from thing definition, item value starts showing “UNDEF” in UI.
Any recommendations to make this shows “%” units everywhere.
