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.
Combining this with similar comments, plus adding in the math to convert to a percent, I tried this:
brightness_pct: "{{state_attr('light.kitchen_sink_ceiling', 'brightness') | float(0) /255*100}}"Still getting the same message
Message malformed: expected float for dictionary value @ data['brightness_pct']For what it’s worth, if I try to set brightness instead of brightness_pct, I get a different message
Message malformed: extra keys not allowed @ data['brightness'](I’m assuming that device just doesn’t accept a brightness attribute - not a big deal to math it out though)
Taking a different approach of starting simple and working up,
100.0 works
{{100.0}} does not work
“{{100.0}}” also does not work
