Brilliant was a Smart Home company who made light switches you could install, replacing your existing ones.<p>They only offered cloud control and APIs were private — they actively rebuffed any attempt by the community around Home Assistant to better support their product.<p>No Matter, nor ZigBee or Zwave, so with the shut down they are another IOT device you essentially need to rip out and throw away, this is painful since they were approximately $350 USD each.
