🏆 Chalice Fogger

The smoking chalice: twenty LEDs lighting the fog from below, switched by a simple on/off radio rather than coded buttons. Battery powered, same board family as the lanterns.

See it working

The chalice fired from the remote — lit fog from the bowl.

The finished chalice: a carved skull goblet on a metal stem, red-lit fog rising from the bowl — The chalice itself — the insert in the bowl lighting the fog from below.

The insert with its cover off: the LED ring on top, an 18650 cell and wiring on the printed frame — Under the cone: the LED ring and the 18650 cell — same board family as the lanterns.

The radio is a switch, not buttons

Unlike the lantern, the chalice doesn't decode remote button codes. Its radio receiver is a latching relay: your remote's ON latches the line, OFF releases it, and the chalice simply follows.

Remote	What happens
ON	the On scene fires — white candle flicker by default
OFF	the Off scene fires — lights out

Because the radio latches, the chalice always agrees with the remote — even after a power blip, it comes back in whichever state the remote left it.

Two fixed scenes

The web page shows exactly two scene cards, On and Off. You can't add, remove or re-pair them (there are no codes to capture) — but the look of On is entirely yours: any palette colour, any effect. Test works as on any prop.

Want the chalice glow to match the lanterns? Set the same palette colour and effect in its On scene. There's no risk of a lantern changing it: config pushes never cross prop types, and the lantern remote means nothing to the chalice's radio.

Power-up behaviour

If the remote is already latched ON when the chalice powers up, the lights come on within a blink — the prop syncs to the switch at boot.
Show-mode WiFi-off (see the main guide) applies here too, but deliberately not in the first couple of seconds after power-up — so a chalice that boots with the remote ON still joins WiFi and stays reachable.

Worth knowing

The capture bar and add/remove scene buttons are hidden on this prop — that's by design, not a fault.
The fog machine itself is separate kit; this firmware drives the chalice's light only.
On the bench, its web page behaves exactly like every other prop's: palette, fleet, settings, firmware all present.
