The best way to keep formaldehyde low is to ventilate indoor air, this not only improves air quality, it also prevents mold

Keep your front and back windows open most of the time, it help air circulating.

Siri can do automation? I doubt it. homekit with apple tv/homepod mini as hub can do automation.

If you don't have homekit hub, then you cannot perform automation using homekit, need to use Aqara/xiaomi hub to run its own automation, if your devices are all aqara or xiaomi brand, then there is no issue to use aqara/xiaomi automation.

if you have multi-brand smart devices that support homekit, then it is wise to get homekit hub (Apple TV/Homepod mini) or setup home-assistant which is more complicated to setup but very powerful for automation

Siri shortcut can only do personal automation, not home automation.

for example, when you were away from home, and someone break in your house and trigger motion sensor, will your siri enabled switch turn on light or siren?

Successful integrated all IP camara with RTSP capability for object detection using nvidia cuda toolkit, and use mqtt to send alerts to home assistant

Components

1. Viseron self hosted NVR with object detection https://github.com/roflcoopter/viseron#cameras
2. Home assistant
3. MQTT
4. nvidia cuda toolkit (required nvidia graphic card)

all above components are running on docker images.

The object detection use nvidia cuda engine to perform object detection based on YOLOv3/4 Darknet using OpenCV
the accuracy is pretty good, it is way better than any motion detection which always giving false alarm, look at the image below which can identify a person pretty far away.




nvidia graphic card utilization, it use quite amount of ram but gpu is running not so hot.



next plan is to setup a new rasbperry pi camera with face detection to enable occupancy detection in rooms.

Many IP camera supports RTSP, I have foscam, tplink, ezviz (hikvision), imou (Da hua), all supports RTSP protocol.

RTSP is a standard protocol for IP camera, you can use opensource NVR software to manage all different brands of ip camera.

I prefer imou ip camera, cheap, very good night vision (it is color!), and able to perform good motion detection with tracking using camera hardware.

all of the software I mentioned are running on docker container, which is hosted by Intel quad Core gen4 cpu, 8GB RAM, 1 x Nvidia 1030 GPU and Ubuntu 20.04 LTS OS
object detection is running in real time, fed by RTSP H264/H265 video streams, you can set the video FPS and the zones, the bigger the zone, the more memory and gpu it used. you also can set the accuracy rate, it can identify person, car, cat, dog and you can configure if you want to trigger the detection by person or other object types

I don't have coral usb accelerator and Frigate doesn't support CUDA to perform object detection, but Frigate is pretty similar to Viseron, both use similar codes.

This is the strangest wiring for three gang switch I have ever seen, is this what you wanted? the live wire run serially through three gangs? must turn on switch A in order to turn on B, and must turn on be A and B in order to turn on C.

Sometime I really amazed by certain people braveness, 240V is no kidding, if you don't know electricity, it could kill you, it could burn your house, it could get your entire family killed in the worst case scenario. don't play play lah ....

If Aqara app set to non china region, then it supports Alexa and Google home

if only use homekit mode, there is no need to set region, but it also means you can't use alexa either.

Only changing china region to other regions or vice versa will cause all of your current devices missing, and you need to redo everything.

you already noticed it.

You are wrong, Xiaomi and sonoff automation are not really done in cloud, automation is run locally, just the setup and devices are managed from cloud.

My xiaomi and sonoff lights turn on in less than 1 second when motion/door sensor detected activity.

me same as @soonwai, aqara hub managed xiaomi devices, automation runs locally in Aqara App (not homekit), response is fast even set in china region.

Use Broadlink RM4 Pro to control your Dooya tubular, then configure Broadlink to integrate to your smarthome system.

it can be done on main stream or substream

I have not yet configured room occupancy as busy working on another IoT high availability setup.

Home Assistant is the solution ,google it or search this thread

As long as there is a CCP Great Firewall in between, don't expect the delay or latency issue can be improved. My Aqara home app get time out frequently as my devices are set in China region.

If you want, we can share the shipping fee, RM75 shipping fee split by two persons is RM37.5, more ppl even cheaper.

I plan to get coral usb for my raspberry pi4
