Hey Guys
I am trying to get my ESP32-P4-NANO + WAVESHARE_10.1"_800x1280_DSI running in ESPHOME
so i got the firmware on it and also ESPHOME in HA recognize it as online, but it doesnt work smoothly as my esp32-s3 display
1.) i get this errors in the log
2.) i also doesnt see anything on the display
maybe i configed something wrong with the backlight or so, but i searched the whole internet for this combo but it looks to be to new, so i guess not many people have got this running
3.) i also constant pinged my esp-p4 and it looks like it reboots every few minutes because its not pingable now and then
4.) here is my current code i tried with
api:
encryption:
key: "xxxxxxxxxxxxxxxxxxxxxxxxxxxx"
ota:
- platform: esphome
password: "xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx"

maybe we have a person here who has allready solved this, i guess this combo from waveshare will be bought many times, so this would help many people
thanks up front for your helps guys

use_address: does not do what you think it does. It is specifically for changing IP address of a known device during OTA flashing and should be used only for the flashing process.
Use manual_ip: - eg:
manual_ip:
static_ip: 192.168.1.136
gateway: 192.168.1.1
subnet: 255.255.255.0
I haven’t look at anything else yet. Try that and see what happens first.

Really? The screen shot shows connection errors and you haven’t posted any logs, so apart from your description it’s a bit hard to diagnose any other issues…
How are you flashing the device? Can you get logs in text format?

Since your backlight component is in PR and still in testing, maybe jump on Discord and see if Clyde is around to answer your issue.
You will need a stable network connection and some text logs first though.

bye the way i just found out that there are more then
one WAVESHARE_10.1”_800x1280_DSI display
i have bought the kit from waveshare
Waveshare ESP32-P4-NANO-KIT-D
the display in this kit should be the modelnumber: 10.1-DSI-TOUCH-A
Anyone gotten POE to work with the somewhat newer small form factor Waveshare POE versions with the POE hat ? Also has a single mic using a supported codec (es8311), at least on the S3, may not be a working component yet on the P4. Still, 25 US for the board with POE hat is a heck of a deal, their S3 variant is the same price with no POE hat. Need to join Discord but finally the form factor I’ve been waiting for with a smaller pico version with no Ethernet available.
