How to debug?
JshGrn opened this issue · 10 comments
Hi, I am fairly new to this I have connected up the unit to my CN-CNT terminal and connected to HA however the temp says 0c and if I set it to cool or another mode it swaps back to off.
The command line says
What can I do to debug the issue? Is there a way I can check if the ESP is actually communicating correctly?
I am just continuously getting:
[17:04:21][V][panasonic_ac.cz_tacg1:248]: Polling AC
[17:04:21][V][panasonic_ac:245]: TX: 70.0A.00.00.00.00.00.00.00.00.00.00.86 (13)
I am using the board 'az-delivery-devkit-v4'
Do you get any RX lines? If not check if your wiring is correct, try swapping the RX/TX pins. The ESP is not getting any data back.
No, the board I am using labels RX and TX as GPO1 and 3, so I even tried adjusting in the config. (https://cdn.shopify.com/s/files/1/1509/1638/files/ESP32_DevKit_C_V4_Pinout.pdf?v=1615364529)
The pin out is here, I have also tried swapping them round.
Additionally, I have tried 16/17 (which are not labeled as RX/TX).
I am not using a logic converter as this board should have it in-built (not getting hot either)
Try 16/17 or 9/10 (both in config and physically). The RX/TX pins on the ESP32 are used for the logger.
Where do you get that from? I am not seeing UART on those pins? I am very new to ESP so maybe I am getting something wrong here.
I just retested 16/17 and flipped but still nothing

That's the ESPHome documentation:
https://esphome.io/components/logger.html
https://esphome.io/components/uart.html
Unfortunately it's hard to debug these issues remotely so you will have to do some measurements on your own to check if your wiring is correct.
Just to clarify something here, my unit has WiFi module built in, and I was following the guide (https://github.com/DomiStyle/esphome-panasonic-ac/blob/master/README.CZTACG1.md), maybe this is causing an issue? I saw others have both working.
If your connector looks identical to the CN-CNT connector on that page you're on the correct guide.
It's possible to connect both of them at the same time, yes.
It works now... very odd, maybe something wasn't connected up right.
My next issue is making the test wire I have into a connector so will now go away and find the connectors I need to connect it 'securely' :)
I am going to be running 4 of these in the same house, will they clash with the same local alias (panasonic-ac.local) or should I set them up manually to be their own host name.
The hostname does not matter, it will simply be harder to identify them when doing network scans. You can always flash them with the same hostname manually and give them a hostname later on via OTA.
