I wonder what it looks like in the HA. I have flashed the binary files into the ESP8266 without hardwiring it to the AC. From the MQTT explorer, I can see the connection but the HA cannot discovered it automatically. Maybe I need to buy the connector and plug it into the CN_WIR port.

If anyone is interested in the above project, ensure your Daikin AC is of the "Smart Control" type or supports WIFI.

Here's how to check it:
1. Open AC front led
2. Check the wiring diagram at the side
3. Observe any port labelled as CN_WIR




Without the CN_WIR port, you can drop the above project and explore other method such as capture and playback the remote control IR signal.


To flash ESP8266, download the bin files from Faikin site and search the binary file using the build-in search function.


Download the ESP8266 flasher app from here if you are not familier with Python apps.

Here the settings that I used, ensure the correct COM port is used.







Once successfully flash, reboot the ESP8266 and try to connect the ESP8266 WIFI AP using your PC/Laptop. Run IPconfig from your Windows command prompt, copy and paste the Default Gateway IP to your browser and enter your desire MQTT Broker IP address, User name and Password.

Next steps will be soldering the jack wire to ESP8266 and plug into CN_WIR port.


Perhaps I rephase your questions also to extend other possible options

Option 1: Wall Power Socket + LAN cable
Option 2: LAN cable only
Option 3: Wall Power Socket only.

Option 1: My preferred option as I will not be limited to CCTV with POE type only, but I can use any other brand that may not support POE. I can extend the usage of the wall power socket for other purpose such as motion sensor, smart plug controlling the hanging LED light for all sort of festival etc.

Option 2: Limited to POE CCTV or any gadget supporting POE.

Option 3: Many CCTV now support WIFI connection such as 2.4GHz or 5GHz. If you plan to save the video stream into DVR, then ensure you have good mesh network.

Got 40amp switch by tuya also
My daikin averages
1 hp - 8.2A
1.5.& 2 hp - 8.5A
So 2.5 above aqara switch probably still sufficient

Buy the ones from lazada, was on sale or something
6” wifi downlight & ceiling light around rm25 each

Need to connect to cn_wir port first then all those climate entities would be automatically listed in HA
My daikin from 10 years ago includes the port, so good chance your existing model is supported

As I understand, POE requires either injector or the switch to support POE. But my (possibly outdated) understanding is also that POE has a slightly higher risk of non-standard components causing devices to fry/burn (because of the increased voltage supplied). If my entire network no POE then theoretically less risk for all the wired devices (but then would need power point for every camera).

Thanks this is helpful. I'm familiar with CCTV which support wifi, as I currently using cheap china device for that (unfortunately the data is cloud-based and calling home to China too, would prefer to move away from that). So for me is option 1 or option 2, I guess as long as aesthetics not an issue option 1 is the most flexible (plus can always be converted to POE later on if the wall socket is needed for something else). Though I think external camera exposed to some splashing from rain maybe POE is safer?

POE switch will perform handshake to device to determine whether it supports POE or not, if it is a non-POE device, it will not provide power to the device.

As long as you have good quality branded POE switch, you don’t really need to worry it.

POE camera is convenient because no need to lay power cable, no need to replace faulty power adapter especially power adapter is concealed in the ceiling, and most importantly, if the POE switch is powered by UPS, you have continue surveillance even power outage.

You think you know it all when using cheap WiFi China CCTV, until...
Those Tuya and Ewelink CCTV are seriously worst than those. Always disconnecting. And if you use if for scenes and automation, you will be seriously disappointed. It is so bad that I only wish they could add into their settings a "Disconnecting" options.

Anything External and waterproof also has it's connectors covered up.

Just share my experience with my recent purchase of a Tuya CCTV.

Reason for the Purchase:

1. My old Xiaomi CCTV installed at my car porch running on 2.4 GHz keeps on being disconnected or the signal unstable. When I check on the number of WiFi APs discovered outdoors compared to indoors, there are simply too many, and some more are using 40 MHz bandwidth for their channel. 

2. I need CCTV that supports 5 GHz (low latency and less interference).

3. CCTV that supports the RTSP protocol can be viewed from HA or any app supporting the RTSP protocol.

The result is within my expectations, except the video quality is not as good as my other 2K FHD Xiaomi CCTV.

I don't mind buying expensive Xiaomi CCTV or quality products if they support 5GHz and the RTSP protocol; otherwise, I will be locked into their ecosystem and not easily integrated into the HA.

NOTE: Not all CCTV supports the RTSP protocol.

Get Dahua, IMOU, TP-link, all support rtsp, POE, ONVIF, very good low light picture, this is important if you want to use it for object/human detection such as Frigate

Frigate with Home Assistant is currently one of the best smart security home systems, it has replaced my old fashion home security system, it has much lesser false alarms, real time monitor and view your house anywhere on earth that have internet connectivity.

Well obviously using CCTV with wifi different from using lan-connected. And more work required to have a local device which records the video/processes the feed. So you recommend to avoid tuya/ewelink for CCTV?

My CCTV are all PoE... so far ok la. Got 1 special wasn't PoE which connects to my NVR via network + injector.

Using hikvision PoE switch.

A random check on the above brands and found many running on congested 2.4GHz band, with a handful on 5GHz band.

Anyone looking for wireless CCTV running on latest technology (e.g. Wi-Fi 6), can add Imou Cruiser Z into your shopping cart.

On the Frigate, I did try to install into my HA on Virtual Machine (VM) but notice the Host CPU usage is at high side. Maybe it more suitable on a dedicated hardware.

Did you notice your CPU usage become higher too with each camera added?

You need both sides to handshake so its not gonna send more power than the device that asks for it.

With cameras in the rain, the camera is usually screwed into a small box where the wires are all located, with the box being attached to the wall. So rain aint getting it, and you can further weatherproof that. Camera itself aint the issue with the weather its just where the power connects to the camera, as long as that is weatherproofed you should be fine.

So Frigate inside of a HA VM? Not really advisable unless youre allocating a lot of resources to that. Maybe HA in bare metal with Frigate as a container then sure, better to have iGPU support really helps.

high cpu usage usually the video decoding is run on CPU, another possibility is object detection is running on CPU too.

my frigate is running on x86 container and use less than 10% CPU, because video decoding is running on intel vaapi hardware decoder, and object detection is on nvidia gpu.

Both of you are using dedicated hardware for the jobs ( ), while I am using my 10-year-old laptop (Intel i5-3320M) as a hypervisor host. 

With 6x containers and 4x VMs running concurrently, CPU utilisation is about 10%. This old laptop still refuses to retire .

If I m not mistaken, Xiaomi C400 model can support 5Ghz

Doesn't make sense 2hp is 8.5A while 1hp is 8.2A, most probably your inverter compressor slow down when ambient temp is cold that's why use less amp. Can check the label at the outdoor unit or catalog, but best is to measure using amp clamp meter. Another important thing is when compressor start it will draw a huge amp for half a second. That will exceed the amp stated on the sticker.

could you share the diagram like how you share it for Daikin? Would like to try it on my ME.

Thank you.

If you need to sort out the correct color cable for each pin, you can use tweezer, pry the tab slightly and pull the cable
