You need to read the router manual to learn how to disable 5Ghz band

People like me only can give you general guideline, specific product requires specific knowledge. no one knows everything.

Just get your old pc (if you have) installed with docker, then you can use docker to run firgate and HA containers.

my environment setup (a bit complicated but you don't have to use my setup)

3 x Ubuntu Server master nodes (1 x86 PC + 2 ARM Single Board Computers) running on Rancher K3S kubernetes cluster
Longhorn storage to mirror container persistent volumes between 2 x Ubuntu Server master nodes
Home Assistant containers running on K3S cluster
Frigate runs on docker container with Coral M.2 PCIe as AI image recognition accelerator
Nginx load balancer ingress engine to handle internet access to HA in K3S cluster
Cert-manager to mange my HA SSL certificate using duckdns.org free dynamic DNS

you cannot compare smart switch with light switch, normal light switch is just a simple on-off passive device, whereas smart switch is active device requires power to control on-off.

When a device is active device, it requires electrical power, it needs a close loop, without neutral line and only live wire, how to achieve close loop? this is why it requires capacitor to achieve it.

Zigbee compatibility between vendors is not good, almost impossible for multiple vendors work together to make their own devices compatible to each other.

Matter is designed to make all future IoT devices to work together.

Thread is another protocol similar to zigbee but based on IP, it intends to replace zigbee/z-wave due to standardization and multiple vendors support

You are wrong, Matter and Thread are open standards, they are meant to solve proprietary issues to lock you in.

Smart relay does not power the device (pump/heater), it creates connection from the power source to the device, hence, it can be used for controlling high power appliances.

sonoff is pretty good at this area, they have smart relay supports 20A current, good for water heater, and it is easily integrate with Home Assistant.

MCB tripped means current overloaded or short circuit, need to check the L/N/E wires whether or not it is shorted.

The relay does not support homekit, as such, in order to use home app, it must be homekit device

You can explore Home Assistant with homekit feature, all home assistant devices can be exposed to iOS homekit as homekit device.

I have sonoff inching ewelink device controlling autogate and managed by home assistant and I exposed it as homekit device, I use my iPhone shortcut to execute autogate open/close through homekit autogate device

Your terncy smart module is not suitable for your autogate controller

as you can see in your autogate board wiring diagram, "P.SW normal" is to open/close indoor (no idea why the autogate got such indoor and outdoor)

The physical switch that connect to "P.SW normal" is a momentary switch or inching switch, a momentary switch example is door bell switch which get connected for a short period to trigger the bell ring, the smart module is supposed to act as momentary switch, however, look at the terncy smart module, it is acted as power connector and provide power to the load such as light bulb, it is not a relay.

Unless the terncy app can configure the switch as virtual momentary switch, then it is possible to use terncy smart module to control autogate.

16A is good enough, 240V x 16A = 3.8kW, I hardly see any aircon requires such high power, my 1.5HP inverter running at full speed only uses around 1kW.

CAT 5E supports 1Gb, no issue at all, if cable length is within 30 meters, it can go up to 5Gb

I have been using the fp2 for almost 2 weeks, this mmWave occupancy sensor is amazing!

It is multi zone’s detection, can act like multiple motion sensors
It is damn sensitive and accurate to few cm, even you are sleeping and it can sense your respiratory movements
It has very fast response times, once you are entering or leaving the designated zone, it triggers in less than a second
You can configure interference zones for fan, curtains to avoid unintended triggers
It works well in HomeKit, so it can work flawlessly with home assistant

The drawback is it requires usb power, hence, not convenient to place at the best spot

Currently the device available in China and can only pair to China region, and the connection to China is damn slow, the setup of zones requires real time connections to China servers, hence, it is not easy to setup. However, detection is locally run and does not require connection to China servers

You can position the sensor downwards to your couch or bed, the sensor has not-so-wide cover area

Interference zones cannot overlap with detection zones, thus, placement is very crucial to get accurate and sensitive detection, I spent two days to find the best spot

120 degree horizontal, actual test is around 100 degree, it will be much less sensitive over 100 degree

It uses AI learning, my standing fan just 3 meter away from fp2 sensor, no interference at all.

Facial detection and object detection for security cameras, reduce false alarms and improve security

I have few Tuya devices, their quality is not consistent probably due to many vendors in one eco system.

Aqara is the most reliable and consistent product I have used.

Among aqara, tuya, xiaomi, smartthings, sonoff, Aqara is the most reliable products. Aesthetically their products are also good looking too.

Yes, you can, it will expose all entities to HA

I also configure HA to expose all entities including HomeKit controller entities back to Apple HomeKit

No need home hub such as Apple TV or HomePod mini at all, HA can act as the home hub!

Frigate coral tpu uses old yolo object detection model which is pretty inaccurate, many times can’t tell person and dogs or cats, so don’t expect it can recognise car plates. This requires custom train model


Enlarge your home location radius, this will help to increase success rate.

My autogate auto open bases on my iPhone gps location running on home assistant companion app, the success rate is over 90%
