  • Add CLI option to pass a data unit when reading in time series data from CSV, so data can automatically be converted to the sensor unit [see PR #341]

  • Add CLI option to specify custom strings that should be interpreted as NaN values when reading in time series data from CSV [see PR #357]

  • Add CLI commands flexmeasures add sensor, flexmeasures add asset-type, flexmeasures add beliefs (which were experimental features before) [see PR #337]

  • Add CLI commands for showing organisational structure [see PR #339]

  • Add a CLI command for showing time series data [see PR #379]

  • Beginning API v3.0 - more REST-like, supporting assets, users and sensor data [see PR #390 and PR #392]

v0.8.0 | January 24, 2022

Warning

Upgrading to this version requires running flexmeasures db upgrade (you can create a backup first with flexmeasures db-ops dump).

Warning

In case you use FlexMeasures for simulations using FLEXMEASURES_MODE = "play", allowing to overwrite data is now set separately using FLEXMEASURES_ALLOW_DATA_OVERWRITE. Add FLEXMEASURES_ALLOW_DATA_OVERWRITE = True to your config settings to keep the old behaviour.

Note

v0.8.0 is doing much of the work we need to do to move to the new data model (see A note on the ongoing data model transition). We hope to keep the migration steps for users very limited. One thing you’ll notice is that we are copying over existing data to the new model (which will be kept in sync) with the db upgrade command (see warning above), which can take a few minutes.

New features

  • Bar charts of sensor data for individual sensors, that can be navigated using a calendar [see PR #99 and PR #290]

  • Charts with sensor data can be requested in one of the supported [vega-lite themes] (incl. a dark theme) [see PR #221]

  • Mobile friendly (responsive) charts of sensor data, and such charts can be requested with a custom width and height [see PR #313]

  • Schedulers take into account round-trip efficiency if set [see PR #291]

  • Schedulers take into account min/max state of charge if set [see PR #325]

  • Fallback policies for charging schedules of batteries and Charge Points, in cases where the solver is presented with an infeasible problem [see PR #267 and PR #270]

Note

Read more on these features on the FlexMeasures blog.

Deprecations

  • The Portfolio and Analytics views are deprecated [see PR #321]

Bugfixes

  • Fix recording time of schedules triggered by UDI events [see PR #300]

  • Set bar width of bar charts based on sensor resolution [see PR #310]

  • Fix bug in sensor data charts where data from multiple sources would be stacked, which incorrectly suggested that the data should be summed, whereas the data represents alternative beliefs [see PR #228]

Infrastructure / Support

  • Account-based authorization, incl. new decorators for endpoints [see PR #210]

  • Central authorization policy which lets database models codify who can do what (permission-based) and relieve API endpoints from this [see PR #234]

  • Improve data specification for forecasting models using timely-beliefs data [see PR #154]

  • Properly attribute Mapbox and OpenStreetMap [see PR #292]

  • Allow plugins to register their custom config settings, so that FlexMeasures can check whether they are set up correctly [see PR #230 and PR #237]

  • Add sensor method to obtain just its latest state (excl. forecasts) [see PR #235]

  • Migrate attributes of assets, markets and weather sensors to our new sensor model [see PR #254 and project 9]

  • Migrate all time series data to our new sensor data model based on the timely beliefs lib [see PR #286 and project 9]

  • Support the new asset model (which describes the organisational structure, rather than sensors and data) in UI and API. Until the transition to our new data model is completed, the new API for assets is at /api/dev/generic_assets. [see PR #251 and PR #290]

  • Internal search methods return most recent beliefs by default, also for charts, which can make them load a lot faster [see PR #307 and PR #312]

  • Support unit conversion for posting sensor data [see PR #283 and PR #293]

  • Improve the core device scheduler to support dealing with asymmetric efficiency losses of individual devices, and with asymmetric up and down prices for deviating from previous commitments (such as a different feed-in tariff) [see PR #291]

  • Stop automatically triggering forecasting jobs when API calls save nothing new to the database, thereby saving redundant computation [see PR #303]

v0.7.1 | November 08, 2021

Bugfixes

  • Fix device messages, which were mixing up older and more recent schedules [see PR #231]

v0.7.0 | October 26, 2021

Warning

Upgrading to this version requires running flexmeasures db upgrade (you can create a backup first with flexmeasures db-ops dump).

Warning

The config setting FLEXMEASURES_PLUGIN_PATHS has been renamed to FLEXMEASURES_PLUGINS. The old name still works but is deprecated.

New features

  • Set a logo for the top left corner with the new FLEXMEASURES_MENU_LOGO_PATH setting [see PR #184]

  • Add an extra style-sheet which applies to all pages with the new FLEXMEASURES_EXTRA_CSS_PATH setting [see PR #185]

  • Set default timezone for new users using the FLEXMEASURES_TIMEZONE config setting [see PR #190]

  • To avoid databases from filling up with irrelevant information, only beliefs data representing changed beliefs are saved, and unchanged beliefs are dropped [see PR #194]

  • Monitored CLI tasks can get better names for identification [see PR #193]

  • Less custom logfile location, document logging for devs [see PR #196]

  • Keep forecasting and scheduling jobs in the queues for only up to one day [see PR #198]

  • Fix GetDeviceMessage to ensure chronological ordering of values [see PR #216]

Infrastructure / Support

v0.6.0 | September 3, 2021

Warning

Upgrading to this version requires running flexmeasures db upgrade (you can create a backup first with flexmeasures db-ops dump). In case you are using experimental developer features and have previously set up sensors, be sure to check out the upgrade instructions in PR #157. Furthermore, if you want to create custom user/account relationships while upgrading (otherwise the upgrade script creates accounts based on email domains), check out the upgrade instructions in PR #159. If you want to use both of these custom upgrade features, do the upgrade in two steps. First, as described in PR 157 and upgrading up to revision b6d49ed7cceb, then as described in PR 159 for the rest.

Warning

The config setting FLEXMEASURES_LISTED_VIEWS has been renamed to FLEXMEASURES_MENU_LISTED_VIEWS.

Warning

Plugins now need to set their version on their module rather than on their blueprint. See the documentation for writing plugins.

New features

  • Multi-tenancy: Supporting multiple customers per FlexMeasures server, by introducing the Account concept. Accounts have users and assets associated. [see PR #159 and PR #163]

  • In the UI, the root view (“/”), the platform name and the visible menu items can now be more tightly controlled (per account roles of the current user) [see also PR #163]

  • Analytics view offers grouping of all assets by location [see PR #148]

  • Add (experimental) endpoint to post sensor data for any sensor. Also supports our ongoing integration with data internally represented using the timely beliefs lib [see PR #147]

Note
