* Rollback modbus to version 0.107.7
Update manifest to not use async.
Rollback entities to sync version.
Keep newer modifications apart from async.
Rollback __init__ to sync version but keep the new functionality.
add async sub directory
Adding the current (not working) version in a sub directory,
to allow easy sharing with a few alfa testers.
The async version are to be updated to use the serial/tcp already
available instead of the flaky pymodbus version. pymodbus is still
needed to encode/decode the messagess.
Update test cases to reflect sync implementation, but
keep the new functionality like e.g. conftest.py.
* do not publish async version
The async version will be made available in a forked repo, until
it is ready to replace the production code.
* update common test for modbus integration
* remove log messages from modbus setup function.
* Make global method local
* Change parameter name to snake_case
Since all entity test functions are going to use
the modbus class, isolate the common parts in
conftest.py, and thereby make it simpler to write
additional test cases.
cleaned up test_modbus_sensor.py while splitting the code.
