Метеостанция Сокол-М читается 1 раз из 200. Какой-то системы и зависимости не установлено кроме того, что первое чтение проходит корректно, а затем - как буд то устройство потерялось.
Замена на другой Сокол-М не помогла.
Существует предположение, что всё работало корректно на прошивке WB 2022 года. После обновления до 2024 началась указанная проблема.
Добрый день.
Вот тут не совсем понятно. Что называете “прошивкой”?
Судя по обилию
WARNING: </dev/ttyRS485-2 19200 8 N 1>: closed due to repetitive errors
устройство не отвечает.
Рекомендую проверить связь, используя modbus_client.
В общем достатчно сотню-другую чтений в цикле чтобы получить статистику.

Отлично. Ну, если wb-mqtt-serial точно был остановлен то видно что устройство не отвечает.
Таймаут ответа по умолчанию - 500мс, можно, конечно добавить -o 700 и проверить гипотезу что отвечает позже. Но судя по тому что ответы то есть то нет - больше похоже на неконтакт, например неконтакт Gnd проводника шины.
Саму шину проверить просто - отключить от контроллера и измерить совпротивление терминатора на дальнем конце.
GND контроллера и метеостанции соединены, -o 700 и даже -o 800 не помог

Ну отлично.
Для того чтобы исключить аппаратные проблемы с портом, например - переключите устройство на другой порт. Ну или опросите его с компьютера.
Другой порт ситуацию не меняет.
С компьютера опросить нет возможности.
В таком случае проверьте саму шину, подключив вместо самого устройства какое-то заведомо работоспособное (проверенное) устройство.
Если с ним будет работать без ошибок - тогда подключите это устройство вместе с метеостанцией.
То есть если одно устройство стоящее на той же шине будет опрашиваться без ошибок а другое - с ошибками то дело в устройстве.
Немного вызывает подозрение, что изменение поведения устройства чётко совпало с обновлением ПО контроллера. Не было ли как-то изменений в управлении ModBus-портами в 2022-2023 годах в ПО контроллера?
Обновление проводилось apt update && apt upgrade
Версий wb-mqtt-serial сменилось довольно много, носам протокол modbus никак не менялся. Но совершенно точно ничего не менялось в modbus_client. Он использует порт напрямую и никак не зависит от остального ПО.
Для уверенности что порт именно свободен, не занят ничем посторонним можно использовать fuser.
Добрый день. Получилось ли проверить?
