3️⃣ Google Home – Step‑by‑Step Guide

3.1 Add the IR Blaster to Google Home

1. Plug in the Broadlink RM4 Pro (or your chosen device) near the AC.
2. Download the Broadlink app (Android / iOS).
3. Follow the in‑app wizard to connect the blaster to your Wi‑Fi (2.4 GHz).
4. In the Broadlink app, “Add Device” → “Air Conditioner” and learn the IR codes (Power, Temp +, Temp -, Mode).
5. Open Google Home → + Add → Set up device → Works with Google → Search for “Broadlink” (or “Sensibo”) and link the account.

If you used a Sensibo Sky, the linking step is Sensibo → Google instead of Broadlink.

3.2 Create Voice Commands

1. In Google Home, the device will appear as “Air Conditioner” (or the name you gave it).
2. Rename it to something room‑specific, e.g., “Living‑Room AC”.
3. Test a simple command:
   
   • “Hey Google, turn on the living‑room AC.”
   • “Hey Google, set the living‑room AC to 23 °C.”

3.3 Build Routines (Automation)

Create a routine by tapping Home → Routines → + Add in the Google Home app.

4️⃣ Amazon Alexa – Step‑by‑Step Guide

4.1 Connect Your IR Blaster to Alexa

1. Open the Alexa app → Devices → + Add Device → Add Smart Home Device.
2. Search for “Broadlink” (or “Sensibo”) and sign in with the same account you used in its native app.
3. Alexa will discover the Air Conditioner as a controllable device.

4.2 Naming & Grouping

• Rename the device to “Bedroom AC” or “Office AC”.
• Add it to a Smart Home Group (e.g., “Living Area”) so you can control multiple devices with one command:
  
  • “Alexa, turn off the living area.”

4.3 Voice Commands & Routines

Create an Alexa Routine:

1. More → Routines → +
2. When this happens: Choose Schedule, Location, Smart Home Device, or Voice.
3. Add Action → Smart Home → Control Device → select your AC and set the desired state (Power On, Temp 22 °C, Mode Cool).

5️⃣ Apple HomeKit – Step‑by‑Step Guide

HomeKit does not natively support most IR blasters, but you can bridge them with Homebridge (a free, open‑source Node.js server).

5.1 Set Up Homebridge (One‑Time)

1. Hardware – a Raspberry Pi 4 (or any always‑on PC).
2. Install Homebridge:
   

   curl -L https://git.io/homebridge-installer | bash
   

3. Add the homebridge-broadlink-rm plugin (or homebridge-sensibo if you use Sensibo):
   

   sudo npm install -g homebridge-broadlink-rm
   

4. Edit the config.json (found in ~/.homebridge) to add your IR blaster’s IP address and learned AC codes. Example snippet:
   

   {
     "accessory": "BroadlinkRM",
     "name": "Living‑Room AC",
     "host": "192.168.1.45",
     "acCodes": {
       "powerOn": "0x1f2e3d4c",
       "temp24": "0x2a1b0c9d",
       "modeCool": "0x3b2c1d0e"
     }
   }
   

5. Start Homebridge (homebridge) and note the QR code displayed in the terminal.

5.2 Add to Apple Home

1. Open the Home app on your iPhone/iPad.
2. Tap + → Add Accessory → Scan QR code (or enter the 8‑digit setup code).
3. The AC appears as a “Living‑Room AC” accessory. Assign it to a room and optionally to a scene.

5.3 Voice Commands with Siri

• “Hey Siri, turn on the living‑room AC.”
• “Hey Siri, set the living‑room AC to 25 °C.”
• “Hey Siri, activate the Evening Cool‑Down scene.”

5.4 HomeKit Automations

Pro tip: If you already have a Ecobee or Nest thermostat, they appear automatically in HomeKit, letting you combine temperature sensing with AC control for tighter climate regulation.

6️⃣ Automation Ideas that Save Energy & Money

All the above can be built in the Google Home Routines, Alexa Smart Home routines, or Apple Home automations.

8️⃣ Safety, Privacy & Data‑Security Tips

1. Use Strong Wi‑Fi Passwords – at least 12 characters, mixed case, numbers, symbols.
2. Enable Two‑Factor Authentication (2FA) for your Google, Amazon, and Apple accounts.
3. Keep Firmware Updated – both the IR blaster and your router receive security patches.
4. Limit Cloud Permissions – only enable the “Control AC” permission; disable location tracking unless you need geofencing.
5. Local‑Only Mode (Advanced) – with Homebridge, you can run a local HomeKit server that never sends data to Apple’s cloud.
