Solved!
Solution was to create a group and perform an action on that:
action: light.turn_on
target:
entity_id: light.kitchen_cabinet_sink
data_template:
brightness_pct: "{{100*state_attr('light.kitchen_sink_ceiling','brightness')/255}}"
Original:
Trying to run an automation to match one light's state (on/off/dim) to another's. Have this currently:
alias: Sync cabinet lights with sink light
if:
- condition: device
type: is_on
device_id: [something]5710
entity_id: [something]a438
domain: light
then:
- type: turn_on
device_id: [something]b447
entity_id: [something]470f
domain: light
brightness_pct: 100
else:
- type: turn_off
device_id: [something]b447
entity_id: [something]470f
domain: light
That works fine to turn the lights on or off, and I have triggers in the automation for that and changes in brightness. But using a non-static number for brightness_pct (yes, I know I'll probably have to math the 0-100 scale instead of 0-255) is giving me trouble. When I try something like this:
alias: Sync cabinet lights with sink light
if:
- condition: device
type: is_on
device_id: [something]5710
entity_id: [something]a438
domain: light
then:
- type: turn_on
device_id: [something]b447
entity_id: [something]470f
domain: light
brightness_pct: {{state_attr("light.kitchen_sink_ceiling", "brightness")}}
else:
- type: turn_off
device_id: [something]b447
entity_id: [something]470f
domain: light
I have also tried {{states.light.kitchen_sink_ceiling.attributes.brightness}} instead. Both seem to have the correct value when I play around in the developer tools. But when I put it in the automation, I get an error that a float value was expected. I see some similar issues online, but it always seems to be in a different context and people fix it by changing some value I never had.****
Especially in the last month or so I've been noticing how uninspiring technology has been. I used to love seeing whatever the gadget of the season was at Target while my mom shopped. Now it's all... Phone cords, and um, printer ink cartridges. The same wireless speakers we bought years ago. Nothing about it is cool anymore!
