Lilygo T-ETH conflict on cs_pin 27?

[TheStapler]

I installed my Lilygo T-ETH board today finally, so I copied the config from here for the board, and then copied in my old sensor: config I was using previously (side note, the config example here doesn't have any of the substitutions listed). After i saved it in EspHome, I tried to validate it and it came back with these errors:

INFO ESPHome 2024.12.4
INFO Reading configuration /config/esphome/homeenergy.yaml...
WARNING GPIO0 is a strapping PIN and should only be used for I/O with care.

Is this something to do with the T-ETH board, or my config somewhere? I just want to make sure before I just move the jumper on that board, that's all!

Yeah, and I can't use cs_pin: 25 or 26 either... the validation fails with the same errors, so am I doing something wrong, and this is unusable for main + 4 addon boards?

Sorry this isn't more clear. Many of the CS pins previously used have to be mapped to the pins on the ESP32-S3. They are listed on the back of the Lilygo adapter. I'll add them to the example configs....

Main board:

• 5 -> 8
• 4 -> 4 (stays the same)

Add-on boards:
CS (CT1-3):

• 0 -> 0
• 27 -> 18
• 2 -> 2
• 13 -> 3
• 14 -> 41
• 15 -> 15

CS2 (CT3-6):

• 16 -> 16
• 17 -> 17
• 21 -> 21
• 22 -> 20
• 25 -> 39
• 26 -> 38

AH... hahah... I never even looked at the bottom of the board... wow, I feel so dumb. LOL!
thanks for clearing it up, and I will take a look at it tonight.
