From 28fa862defd62dd89804fc57a2ed5d2714a1d20a Mon Sep 17 00:00:00 2001 From: "copilot-swe-agent[bot]" <198982749+Copilot@users.noreply.github.com> Date: Fri, 15 May 2026 11:59:33 +0000 Subject: [PATCH 01/24] cli/data_add: add --timezone to add_holidays; add holidays-by-package command; add future-annotation-regressors to pipeline schema Context: - add_holidays stored UTC midnight timestamps, causing holidays to appear at wrong local time (e.g. 1AM in Amsterdam) in the UI - No support for the 'holidays' Python package which covers more countries and school holidays not in workalendar - No way to pass annotation-based binary regressors to the forecasting pipeline Change: - Add --timezone option to 'flexmeasures add holidays'; holidays are now localized to the given timezone (UTC when omitted, with a warning) - Add new 'flexmeasures add holidays-by-package' command backed by the 'holidays' package; supports --country, --subdiv, --category, --timezone - Add 'holidays>=0.57' to pyproject.toml direct dependencies - Add future_annotation_regressors field (data_key: future-annotation-regressors) to TrainPredictPipelineConfigSchema for annotation-based binary regressors Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com> Co-authored-by: Flix6x <30658763+Flix6x@users.noreply.github.com> --- documentation/changelog.rst | 3 + flexmeasures/cli/data_add.py | 181 ++++++++++++++++++ .../data/schemas/forecasting/pipeline.py | 16 ++ pyproject.toml | 1 + uv.lock | 2 + 5 files changed, 203 insertions(+) diff --git a/documentation/changelog.rst b/documentation/changelog.rst index 14a4139ecf..830d3fc035 100644 --- a/documentation/changelog.rst +++ b/documentation/changelog.rst @@ -18,6 +18,9 @@ New features * New ``GET /api/v3_0/sources`` endpoint to list accessible data sources and defined types, with ``only_latest=true`` by default to return only the most recent version per source [see `PR #2126 `_] * Add support for filtering sensor data GET requests by ``source-type`` on ``/api/v3_0/sensors//data`` [see `PR #2127 `_] * Making monitoring alerts more flexible: allow ``flexmeasures monitor`` alerts to target one or more user IDs or email addresses with ``--recipient``; ``flexmeasures monitor last-seen`` can now narrow monitored users to one or more accounts with ``--account`` or to client accounts with ``--consultancy`` [see `PR #2158 `_] +* Add ``--timezone`` option to ``flexmeasures add holidays`` to store holiday annotations at local midnight instead of UTC midnight [see `PR #2176 `_] +* Add new ``flexmeasures add holidays-by-package`` command backed by the ``holidays`` Python package, supporting more countries and school holidays [see `PR #2176 `_] +* Add ``future-annotation-regressors`` field to the forecasting pipeline config schema, allowing annotation sources (e.g. holidays) to be used as binary future regressors [see `PR #2176 `_] Infrastructure / Support ---------------------- diff --git a/flexmeasures/cli/data_add.py b/flexmeasures/cli/data_add.py index 112b21dd4c..fff3d4bd70 100755 --- a/flexmeasures/cli/data_add.py +++ b/flexmeasures/cli/data_add.py @@ -29,6 +29,7 @@ from timely_beliefs.sensors.func_store.knowledge_horizons import x_days_ago_at_y_oclock import timely_beliefs as tb from workalendar.registry import registry as workalendar_registry +import holidays as hpkg from flexmeasures import Forecaster, Reporter from flexmeasures.cli.utils import ( @@ -953,16 +954,39 @@ def add_annotation( preferred="--account", help="Add annotations to this account.
