🪼 Jellyfish

The swimming jellyfish: sixteen LEDs in the bell, a motor that swims it forwards or backwards at variable speed, and the same coded RF remotes as the lanterns. Three units.

Scenes: light, motion, or both

Pairing remote buttons works exactly like the lantern — capture a code into a scene card. What's new is the motor row in every card:

Motor setting	What happens
unticked	this scene doesn't touch the motor — a pure lighting cue while the jellyfish keeps swimming (or stays still)
ticked, slider at 0	explicit stop
ticked, slider right	swim forward — further right is faster
ticked, slider left	swim in reverse

Typical setup: one button for "glow + slow swim", one for "colour change only" (motor unticked), and an all off blackout scene — the all-off button in a card fills in lights-off and motor-stop in one click.

The motor always stops at power-on and during firmware updates, whatever scene was last active. Motion only ever starts from an explicit scene.

Motor calibration

Each jellyfish's motor controller is slightly different, so Settings has two numbers per unit (these appear only on motor props):

Setting	Meaning
Motor PWM offset	the stop point. The motor must not turn when a scene sets speed 0. If it creeps, nudge this value until it holds still.
Motor PWM range	how much swing full speed adds either side of the stop point — effectively the top speed.

Fire a scene with motor ticked and the slider at 0.
Adjust the offset until the motor is truly still — changes apply the moment you save, so you get instant feedback.
Slide a test scene to full and trim the range to taste.

Calibration is per-unit and survives config pushes: syncing scenes across the three jellyfish never overwrites each unit's tuned values.

Running three jellyfish

Set up one unit's scenes, then push config from its Fleet page to the other two — they keep their own names and calibration.
Give them a shared group (e.g. jellyfish) so lantern pushes can't touch them, or individual groups if each swims to different cues.
One remote button can drive all three at once — capture the same button into each unit's scene (radio is broadcast; they all hear it).

Worth knowing

Held buttons fire once, same as the lantern — a scene doesn't re-trigger until the button is released.
Power is a rechargeable cell + charger board; the motor is the main drain when swimming, WiFi when idle — show mode (WiFi-off on first press) applies here too.
A lighting-only scene fired mid-swim genuinely leaves the swim alone — that's the no change feature, not luck.
