Changelog#

1.1.0 - September 12, 2023#

🚀 New#

  • Allow to set the connection timeout when initialising Drift.

⚙️ Engineering#

  • Lint with ruff.

  • Update codebase to work with pymodbus 3.5+.

1.0.2 - March 10, 2023#

🔧 Fixed#

  • Pin pymodbus<3.2.0. This versions removes the protocol attribute in AsyncioModbusTcpClient and breaks drift. It will be fixed in a future version.

1.0.1 - December 24, 2022#

🔧 Fixed#

  • Fixed reconnection. pymodbus now set the host to None after the transport closes, so it needs to be rested before reconnecting.

1.0.0 - December 24, 2022#

🚀 New#

  • Dropped Python 3.7 and add support for 3.11 with pymodbus>=3.0.0.

0.4.5 - November 9, 2022#

🔧 Fixed#

  • Release lock if connection fail in Drift.__aenter__.

0.4.4 - May 25, 2022#

🚀 New#

  • Drift() can now be initialised with lock=False which will disable the locking of the client while the context manager is used. In this mode, multiple concurrent connections to the client are allowed.

  • Added Drift.read_devices() which allows reading multiple devices concurrently with only one connection to the client.

  • Drift.devices returns a list of all connected devices.

✨ Improved#

  • Module does not require to pass a number of channels anymore. In fact the number of channels is never used so it may be deprecated in the future.

  • Add poetry dependency groups.

0.4.3 - May 13, 2022#

🎨 Engineering#

  • Use latest pre-release version of poetry core, do not require setuptools, and test for 3.10.

0.4.2 - May 11, 2022#

✨ Improved#

  • Drift.from_config() now accepts keyword arguments that are passed to __init__().

0.4.1 - February 4, 2022#

🚀 New#

  • #9 Device now accepts a data_type argument that follows the same format as the struct module and allows to cast the read raw value from unsigned 16-bit integer to a different type, before passing it to an adaptor.

0.4.0 - December 14, 2021#

💥 Breaking changes#

  • Device addresses now must include the offset (i.e., 40001 is not subtracted).

🚀 New#

  • Add proportional adaptor.

0.3.0 - October 12, 2021#

🚀 New#

  • Add the option to add an offset to the read value after applying the adaptor.

✨ Improved#

  • Updated documentation theme to furo.

🔧 Fixed#

  • Fix case when linear adaptor range does not start at zero.

0.2.5 - August 1, 2021#

✨ Improved#

  • Added gain parameter to voltage adaptor.

0.2.4 - July 27, 2021#

🔧 Fixed#

  • #7 If the connection to the client fails, release the lock immediately.

0.2.3 - July 15, 2021#

🔧 Fixed#

  • #5 Fixed an error that would happen when switching the first (channel 0) bit in a holding register. In that case the code would just set the entire register, ignoring the other set bits.

0.2.2 - May 18, 2021#

🔧 Fixed#

  • Fix a nasty bug that would force all relays to be of mode coil even if its module has been defined as a holding_register. Also, fix the writing of bits when channel is set in a holding register.

0.2.1 - February 23, 2021#

🔧 Fixed#

  • Add a lock to the connection context manager to prevent multiple simultaneous connections disconnecting the client.

0.2.0 - February 22, 2021#

🚀 New#

  • Major rewrite of how addresses, channels, and modes work.

  • Rename E+E adaptors and add rtd10 adaptor.

  • Add voltage, pwd, flow, and linear adaptors.

🔧 Cleanup#

  • #4 Add typing and use Black formatting.

0.1.5 - October 10, 2020#

🔧 Fixed#

  • #3 Fix import of AsyncioModbusTcpClient when using pymodbus>=2.4.0.

0.1.4 - August 19, 2020#

🔧 Cleanup#

  • Do not require extra dev for sdsstools.

0.1.3 July 30, 2020#

🚀 New#

  • Add Drift.read alias to Drift.read_device.

🔧 Fixed#

  • Fix Drift.get_device not working for case-insensitive devices.

0.1.2 - July 29, 20202#

🔧 Cleanup#

  • Relax sdsstools version to allow jaeger to bump the minimum version.

0.1.1 - July 19, 2020#
