I do not think that combining smart presence sensors with heating systems is the best idea, at least not for some basic automations. It is a huge topic, and many times, keeping the heating on steadily throughout the day is better than turning it on and off constantly. Like with the car on the highway. But I am not an expert, and it really depends on a heating source (radiators, floor heating, heating panels, AC…).
Thanks for your insight! You’re right – constant on/off switching can be inefficient, especially with systems that take longer to heat up or cool down.
In my case it’s a small electric heater, so the warm-up is almost instant, but I’m trying to avoid it running when the room is already comfortable. I was thinking about combining temperature + humidity thresholds with FP2 zones, so it only runs if I’m actually in the room and conditions meet the trigger.
Have you tried anything similar with different sensors or rules?
Yeah, I’ve heard mixed results about IR control for AC – especially when the signal path isn’t perfect or the AC has a bit of a “lag” in responding.
I was thinking the FP300 might help here since it combines presence + environmental data in one device. If it could trigger scenes more reliably, maybe it would solve part of the IR timing issue.
Have you tried adding a short delay or a condition check before sending the IR command? Sometimes that could makes it more consistent.
I’ve got the AC set up with the M3 hub, paired it with a temp sensor and if it’s too or (will be)hot outside, the house is warming up and occupied, then the AC starts to cool to the set temperature.
If the door sensor detects the door open for too long, then it stops the AC from wasting energy.
It is a heat pump, so this applies to warming up in the winter. And saving energy if the house is not occupied.
That’s a great setup – I like the way you’ve added the door sensor as a condition to avoid wasting energy. It’s a simple but very effective safeguard.
I’m curious, do you find the M3 hub responds faster for AC control compared to IR blasters like the G3? I’m wondering if the direct hub connection makes the triggers more reliable, especially with rapid temperature changes.
I find them working about the same speed. Not sure if you could even measure/notice a difference. I’m not sure you can integrate the G3 as an AC controller @AqaraBot may confirm or not
@P4ck0 It’s great to hear about your interest in optimizing your smart home setup! Regarding your question about integrating the Camera Hub G3 as an AC controller, the Camera Hub G3 does have a built-in infrared (IR) controller. This feature allows it to learn and control various infrared-compatible devices, which includes many AC units. You can program the G3 to control your AC, even if it’s not listed in the G3’s infrared database, making it a flexible choice for managing your climate control needs.
However, the response speed might not drastically differ from other hubs like the M3, as both are designed to operate efficiently within their ecosystems. The advantage of using the G3, though, is its ability to combine video surveillance with device control, adding an extra layer of functionality and convenience.
If you try integrating the G3 with your AC, it would be wonderful to hear about your experience and any creative automations you develop!

Question: How are you combining Aqara devices for heating or AC control? Any tips or creative scenes?
You’re right – constant on/off switching can be inefficient, especially with systems that take longer to heat up or cool down.
