DIY Smart Home Hack: Maximizing Matter for Energy Efficiency

Hey , wanted to share a little weekend project that turned out way cooler than I expected — and actually saved me some coin on the energy bill.

I’ve been running a decent Matter-powered setup for a while now (lights, plugs, thermostat, the works), but I realized I wasn’t really using its full potential for energy efficiency. So I dove into automations.

What I did:

  • Used my Matter-compatible door and window sensors to cut off heating/cooling in specific rooms when windows are open.
  • Created a “no one’s home” scene triggered by my phone and my partner’s phone leaving the area. It turns off all lights, kills standby power via Matter plugs, and puts the thermostat in eco mode.
  • Added sunrise/sunset behaviors to smart blinds and lights — seems small, but it made mornings smoother and less energy-hungry.

The coolest part? All of this was done with Aqara sensors and some HomeKit and Google Home help. I didn’t need to switch platforms or code anything crazy.

Energy usage dropped about 10% after a two-week test run — not huge, but for a few tweaks? I’ll take it.

Curious if anyone else has done something similar, or if you’ve got smarter hacks I could steal. Let’s turn Matter into a money-saver, not just a smart toy. @AqaraBot

@GoogleHomeGuru What a fantastic weekend project! :tada: Your creative use of Matter and Aqara sensors to boost energy efficiency is seriously impressive—especially that 10% drop in energy usage. Love how you leveraged door/window sensors for heating control and built a “no one’s home” scene; those are brilliant automations that truly showcase Matter’s potential.

The sunrise/sunset behavior for blinds and lights is such a subtle but impactful touch too. It’s awesome to see how small tweaks can make a smart home both more intuitive and cost-effective.

Your setup is a great example of how Matter’s multi-ecosystem flexibility (like mixing Aqara, HomeKit, and Google Home) can simplify automations without needing complex workarounds. Thanks for sharing these actionable tips—I’m sure others in the community will be inspired to try similar hacks!

If anyone else has energy-saving tricks with Matter or Aqara devices, chime in—let’s keep the ideas flowing! :bulb:
