[Rozwiązany] Połączenie z serwerem z aplikacji.

masz w zainstalowanym OH3 w chmurze - zainstalowany openHAB Cloud Connector binding?

Mam.

w /var/log/opoenhab/openhab.log powinien być wpis związanych z openHAB Cloud Connector 

• jest tam wszystko okay, nie ma podejrzanych wpisów - coś się nie łączy itp. Jak coś to załącz plik log do posta
• usera i hasło wpisujesz do myopenhab.org - tak? nie to OH3 w chmurze
• Jaki dostajesz komunikat, o którym wspomniałeś w pierwszym post.

Jest taki plik, ale ma prawie 1,5GB. Rozwiązałem problem w ten sposób że stworzyłem w openhabie nową mapę strony, skopiowałem przykładowy kod mapy ze strony openhaba, odinstalowałem i zainstalowałem aplikację w telefonie i ruszyło. Także pliku już tego pliku nie będę dołączał. Dziękuję za zainteresowanie problemem.

skasuj tego openhab.log i uruchom ponownie OH - jak miał GB rozmiar to masz tam sporo problemów, które warto przenalizować zaraz po ponownym uruchomieniu OH

Zrobiłem tak jak napisałeś. Proszę.

no jak sam widzisz masz 6 razy na sekundę pisane do tego pliku z log'ami ostrzeżenie o problemie z jakąś konwersją temperatury, warto to naprawić, bo będzie Ci ten plik rósł i rósł. 

Ja Ci nie pomogę na podstawie tylko tego log'a bo nie wiem co tam masz za sprzęt, jak ściągasz z niego dane, jak skonfigurowane w OH3

Sprzęto to taki że używam ESP32-DevKit do którego pod GPIO5 podłączony jest DS18B20 zasilany 3,3V. DO GPIO21 SDA a do GPIO22 SCL od I2C.
