Unable to send/receive data
Closed this issue · 12 comments
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?

Hi. The wiring looks pretty good to me. Nothing obviously wrong.
- Are you wiring the RESETn pin to ground as documented in the README?
- Are you seeing anything in the device logs?
- You can enable UART debugging to see if there's any traffic flowing.
e.g.
uart:
baud_rate: 115200
debug:
direction: BOTH
after:
delimiter: "\n"
sequence:
- lambda: UARTDebug::log_string(direction, bytes);- Yes, wired Q16 to GND
- The only thing I see in the logs is device ready over and over again.

Is the WiFi LED on your Winix on? If not, press the WiFi button and it should start blinking then go solid
Hmm that must be the issue then.
I pressed the WiFi button to turn it on.
LED blinks but never goes solid.
Anything different in the logs?
Messages show up but are not controlling the actual state or receiving the current state.
Looks like your UART connections are OK it's just that the handshake isn't completing properly.
Did you press and hold the WiFi button? It should just be a short press since you don't want the Winix MCU to think the WiFi is in AP mode.
I did press and hold the WiFi button which is how I got the LED to start blinking and the logs to show MCU ready.
When LED is off, and I press the WiFi button, nothing happends; LED is still off.
I can only get it to blink when I press and hold and it still never goes solid.
Gotcha. I'm guessing you never setup the OEM Wi-Fi? There's probably some extra handshake needed for that case. I'll review the captures I took in the past and see what else might be needed
You are correct. I never setup the OEM WiFi.
I removed the RESET wire to setup OEM WiFi. There was a firmware update so I updated the machine.
After setup was complete I put back the RESET wire and now everything works.
I wonder if it's because I was on an older firmware.
Thanks for your help!
Ah haha, I was actually just working on support for the AP handshake in #10.
Either way, glad it's working for you.

Ah okay, I have another C545 that I was planning on upgrading later this week so I will try out the new AP handshake.
Thanks!
