IKEA MYGGSPRAY - Smart Motion Lights

Smart motion lighting for IKEA MYGGSPRAY Matter-over-Thread sensors and
other Home Assistant motion detectors.

Behaviour:
- Starts when any selected motion detector reports motion, at least one
  selected illuminance sensor is below the chosen threshold, and every
  selected light is off and available.
- Motion-only detectors are supported; illuminance can be supplied by
  separate detectors that expose light-level entities.
- Sends brightness and colour in the same light.turn_on call, avoiding an
  intentional "turn on, then dim/recolour" sequence.
- Turns the lights back off after occupancy has stayed continuously clear
  for the configured time.
- Remembers each light's latest normal ON brightness/colour while idle and
  can restore that profile immediately before automatic switch-off.
- Manual/external OFF immediately releases the current motion-light session.
- Recovers from stale session locks when all target lights are already off.
- Cleans up after sensor/light faults and has a maximum-runtime failsafe.
- Supports extra user-defined activation conditions.

Previous-profile memory:
Home Assistant reports active brightness/colour attributes as null while a
light is off. Without requiring helpers, this blueprint keeps temporary
dynamic scenes whenever target lights are normally ON. Profile tracking is
locked while motion lighting owns the lights, so the automation profile
cannot overwrite the remembered normal profile.

Dynamic scenes are temporary. They are cleared by a Home Assistant restart
or scene reload and are relearned the next time each light is used normally.
If no profile has been learned yet, cleanup still turns the light off but
cannot pre-load its previous brightness/colour first.

Flash prevention:
Home Assistant cannot generically pre-stage brightness/colour while a light
is physically off. This blueprint therefore sends brightness and colour in
one turn_on command. A bulb that itself briefly recalls an old hardware
state before applying that command cannot be fully prevented by a blueprint.

This blueprint starts a motion-lighting session when any selected motion detector reports activity, at least one selected illuminance sensor says the room is dark enough, and every selected light is off and available. Motion-only detectors are supported because the illuminance entities are selected separately. It can remember the latest normal light profile, restore it before switch-off and clean up after manual changes, unavailable entities or an overlong session.

Before you start

Pair the MYGGSPRAY with Home Assistant through Matter-over-Thread.
Identify the occupancy or motion entities covering the area and at least one

illuminance entity. They do not have to belong to the same devices.

Make sure the target lights can be controlled normally from Home Assistant.

Configure

Import the blueprint and select Create automation.
Select one or more motion/occupancy sensors, one or more illuminance sensors,

and the target lights.

Choose the lux threshold, automation brightness and optional colour.
Set the clear delay and maximum session runtime.
Optionally add activation conditions, then save and test in a non-critical

room first.

The remembered profiles use temporary dynamic scenes. A Home Assistant restart or scene reload clears them; the blueprint learns them again the next time the lights are used normally.

Troubleshooting

Motion does not start a session: check the current lux value and confirm every

target light is both off and available.

Lights turn off while part of the area is occupied: confirm every selected

motion detector reports on while it detects activity. The clear delay starts only after all selected detectors report off.

A previous profile is not restored: use the light normally while the motion

session is idle so a fresh profile can be learned.

A bulb briefly flashes an old colour: some bulbs recall their hardware state

before applying Home Assistant's combined brightness and colour command. A generic blueprint cannot pre-stage a physically powered-off bulb.
