Mam podłączone i skonfigurowane BMS Daly do esphome i drugi zestaw pzem-004T podłączone do innego esphome.  
Chcę podłączyć BMS i Pzem do jednego wt32-ETH01  
Wiem że dostępne 3linie Uart.  
Ma ktoś przykładowy kod aby sensory wykorzystywały odpowiednie Uart1/Uart2

Jeśli już masz coś skonfigurowane i działające, to należy podać wszystkie dostępne informacje zakładając nowy temat, bo chcący ewentualnie pomóc nie będą musieli szukać informacji w internecie, a Ty je masz przed nosem i liczysz przecież na pomoc. [Podasz kody YAML](https://forum.arturhome.pl/t/jak-prawidlowo-zamieszczac-yaml-inny-kod-lub-logi-w-postach-na-forum/11455) swoich konfiguracji ESPHome i może otrzymasz gotowca łączącego wszystko w całość. Minimum wysiłku, to wrzucenie linków do dokumentacji ESPHome dla komponentów, o które pytasz.

Widziałem ten artykuł i od tygodnia próbowałem różne warianty łącznia i za każdym razem nie miałem połączenia z żadnym z urządzeń.

Jedyna różnica między konfiguracjami jest wykorzystanie innych płytek esp z lanem i bez.

Żeby nie leżało koło siebie kilka esp32 mam zamiar przejść na jeden wt32-eth01

Na początek zmienił bym `boards` na `wt32-eth01` podążając za listą:

> **[Boards · platformio/espressif32](https://registry.platformio.org/platforms/platformio/espressif32/boards?p=15)**

> ESP32 is a series of low-cost, low-power system on a chip microcontrollers with integrated Wi-Fi and Bluetooth. ESP32 integrates an antenna switch, RF balun, power amplifier, low-noise receive amplifier, filters, and power management modules.

[https://docs.platformio.org/en/latest/boards/espressif32/wt32-eth01.html](https://docs.platformio.org/en/latest/boards/espressif32/wt32-eth01.html)

Proszę jeszcze o próbkę Twojego kodu z użyciem dwóch UART.  
Właśnie dziś wpadła do mnie płytka z WT32-ETH01 więc może znajdę czas na testowanie.

Zebrałeś logi podczas kompilacji, wskazują na jakiś błąd? Jak przebiega walidacja YAML?

EDIT:  
Może być potrzebne określenie adresów i ID dla sekcji `modbus`.
