I believe I have successfully wired up a revised board found in the wiki.
I did get it to connect once and see UART comms, but all marked as "invalid sentence" (~logs.txt)

On fresh power on, outright no connection, (ICT DEVICEREADY) with the winix showing a blinking led.

Any thoughts? Is this a handshake issues?

Hello, I looks like I have a different board revision than what is in the tutorial (although they are both v1). Below are some images of the board and info.
I was able to trace the RX and TX to a empty through hole (labeled MCU_TP) which I soldered screw terminals to. Unfortunately, I was unable to figure out how to pull the RST pin for the wifi down. The rst pin now heads into an unlabeled chip. Luckily the code works on this board revision and I had no trouble with anything else.

Board:

• Revision: 1.0
• Name: C545 PBA DISPLAY_WFM50
• Production date: 2021

MCU:

• Manufactuer: ABOV
• Model: A31G123RLN
• Product Page

WiFi:

• Manufactuer I&C Technonolgy
• Model: WFM50-SFC201
• Product Page

The component current causes the warnings in the following form to be generated when packets are received.

[00:00:00][W][component:204]: Component xxxxxx took a long time for an operation (x.xx s).
[00:00:00][W][component:205]: Components should block for at most 20-30ms.

Some targets for optimization are:

• Reduce buffer sizes for max sentence length
• Don't zero-init buffers
• Reduce std::string allocation
• Reduce logging

Hi, thanks for putting this together. I haven't opened up the C545 yet but is there any possibility for control over the leds as well? Would love to be able to disable the "sleep" mode light entirely or after a few seconds/minute after this mode is enabled.

The Auto and Sleep switches should ideally be presets, not switches.

However, this is not currently possible due to missing support in ESPHome (esphome/feature-requests#1661).

Thanks to some back and forth info exchange with @mill1000, I was able to narrow it down to an issue with sscanf and %3d for uint16_t api_code.

The issue appears to be completely fixed (#6 ), but might need to be tested on an ESP32 just to make sure it doesn't cause issues there.

New to ESPHome so not sure if I configured everything correctly but I followed the wiring as referenced in the photos.
I see all the controls in Home Assistant but they don't actually change the state of the machine.
Also sensor data like AQI or light intensity show up as Unknown.

Am I missing something?
