A blueprint for Home Assistant to sync the state and brightness of one light to another light(s)
The following recommended settings will help make the transitions more fluid:
- Transitions from on to off should be set to 0 for all devices
- Initial On Level should match for all devices
- The device settings for the Control Light should not have a minimum brigtness
- Slow down the dimming speed on the Control Light to account for lag
Please note, the Control Light brightness must be able to scale between 1-100. When Minimum Brightness is > 1, the script will ensure the Target Light never falls below that value, with an adjusted linear scale between the minimum value and 100%. Because of this, the brightness value for each light will appear different.
