// The cheap universal IR bridge

Broadlink

Inexpensive infrared and RF blasters that can learn the codes from any handset - aircon, TV, fan, projector, old audio gear. Crude compared with a proper integration, and indispensable for the things that have no other route.

Why we use Broadlink

  • Learns codes from any IR handset, so it can control equipment that has no smart option whatsoever.
  • Some models can be controlled locally without the vendor cloud once set up.
  • Very cheap, and one unit covers a whole room.
  • The RF models can also control older ceiling fans and gate remotes.

Where we do not, and why

  • One-way, with no state feedback. The system is guessing at what the device is doing.
  • Line of sight required, so placement matters and furniture breaks it.
  • Initial setup involves the vendor app and account.
  • It is a fallback rather than a design choice.

Where it fits in a CtrlSpace build

Used for the leftovers - an old projector, a ceiling fan with only an RF remote, a legacy amplifier. Never for something that has a proper integration available.

// Frequently asked

Broadlink, answered plainly

Why would I use an IR blaster instead of a real integration?

Only when no real integration exists. Plenty of equipment in a Singapore home - older fans, projectors, legacy audio - has nothing but a handset, and this is the way to bring it in.

Does the system know if the device actually turned on?

No. Infrared is one-way. Where state matters, we pair it with something that measures reality, such as a power-monitoring plug that can tell whether the device is drawing current.
