Smart home cooling doesn't have to be overwhelming. This checklist walks you through setup in order: assess your AC, choose devices, install, connect, create your first automation, and verify. Follow it step by step and you'll have automated, money-saving AC control in a weekend.
Phase 1: Assess Your Setup
Before buying anything, understand what you have. Note your AC type (window, split, central), brand, model, and whether it has Wi-Fi. Check if you have a smart speaker (Google, Alexa) or plan to use your phone only. This determines which products to buy.
| Your AC Type | Recommended First Purchase | Est. Cost |
|---|---|---|
| Wi-Fi smart AC | Nothing (use brand app) | ₹0 |
| Window AC, conventional | Smart plug (energy monitoring) | ₹1,000–2,500 |
| Split AC, conventional | IR blaster | ₹1,500–4,000 |
| Multiple ACs | IR blaster + smart plug for one | ₹2,500–5,000 |
Phase 2: Buy and Install Devices
Order devices that match your AC and ecosystem. Install smart plugs between socket and AC (ensure plug supports AC load). Place IR blaster where it has line-of-sight to the AC's IR receiver. Connect devices to Wi-Fi via their apps. Name them clearly (e.g., "Living Room AC").
Phase 3: Connect to Your Hub
Add devices to Google Home or Alexa. Open the assistant app → Add device → discover. Assign rooms. Test basic on/off and temperature (if supported). If using an IR blaster, ensure the AC is in its database or teach it your remote's signals.
Phase 4: Create Your First Automation
Start with one simple automation: a schedule. "Turn off Living Room AC at 10 PM" or "Set AC to 26°C at 9 AM on weekdays." Test it. Once it works, add another: "Turn on AC at 6 PM." Build up; don't create 10 automations at once.
| Automation | Trigger | Action | Savings |
|---|---|---|---|
| Away mode | Time (e.g., 9 AM–6 PM weekdays) | AC off or 28°C | 15–25% |
| Sleep mode | Time (10 PM) | AC 25°C or sleep mode | 5–10% |
| Pre-cool | Time (5:30 PM) | AC on, 24°C | Comfort (not savings) |
| Voice "Good night" | Routine | All ACs sleep or off | Prevents forgetfulness |
Phase 5: Optional Upgrades
Once basics work, consider: a temperature sensor for temp-based triggers; occupancy sensor for "turn off when empty"; smart fan to pair with AC; energy monitoring to track savings. Add one at a time and test.
Verification and Troubleshooting
Run your automations for a week and verify they fire correctly. Check the app or smart plug for runtime and kWh. If something fails, check: Wi-Fi stability, device placement (IR line-of-sight), schedule overlap, and correct room/device names.
FAQs
Do I need a smart speaker for automation?
No. Schedules and routines can run without voice. A speaker is convenient for manual control and voice triggers but not required.
What if my IR blaster doesn't support my AC?
Most blasters have "learn" mode. Use your existing remote to teach it each button (on, off, temp up/down, mode). Takes 10–15 minutes.
Can I use a smart plug with a split AC?
Split ACs draw 10–20A. Most smart plugs handle 10–16A. Check your AC's specs and the plug's max load. Heavy-duty plugs exist for 20A.
How long does setup take?
First device: 15–30 min. First automation: 10 min. Full checklist (through Phase 5): a weekend if you add sensors and fine-tune.
What's the first automation I should create?
Away mode—turn AC off or to eco when you leave for work. Biggest impact for office-goers. Use time-based or geo-fence if supported.
How do I know if it's saving money?
Use a smart plug with energy monitoring and compare kWh before/after. Or use our AC Energy & Cost Calculator to model savings.
