I am trying to write a python script to read an OSM file and modify its thermostat setpoints schedules during some peak perids. does anyone know how can I modify thermostat schedules in OpenStudio (OSM) file using python?
pip install openstudio. Make sure you use python 3.7 to 3.10, see the OpenStudio SDK Python Binding Version Compatibility Matrix
Then it's a matter of using the SDK to modify the schedule. Depends which schedule type is used (eg: ScheduleRuleset).
A short example:
In [1]: import openstudio
In [2]: openstudio.openStudioLongVersion()
Out[2]: '3.6.1+bb9481519e'
In [3]: m = openstudio.model.exampleModel()
In [4]: sch_ruleset = m.getScheduleRulesets()[0]
...: print(sch_ruleset)
OS:Schedule:Ruleset,
{759b60e6-ce95-4ff3-8400-2162e0d007be}, !- Handle
Medium Office Cooling Setpoint Schedule, !- Name
{1f748523-f5e7-4388-8c2d-3aed545795c2}, !- Schedule Type Limits Name
{91357986-488a-469e-8dca-cd87a7647e4b}, !- Default Day Schedule Name
{d651ceae-2f44-465b-9617-554befb57e9b}; !- Summer Design Day Schedule Name
In [5]: sch_day = sch_ruleset.defaultDaySchedule()
...: print(sch_day)
OS:Schedule:Day,
{91357986-488a-469e-8dca-cd87a7647e4b}, !- Handle
Medium Office Cooling Setpoint All Other Days Schedule, !- Name
{1f748523-f5e7-4388-8c2d-3aed545795c2}, !- Schedule Type Limits Name
, !- Interpolate to Timestep
24, !- Hour 1
0, !- Minute 1
26.7; !- Value Until Time 1
In [6]: sch_day.clearExtensibleGroups()
...: sch_day.addValue(openstudio.Time(0, 12, 0), 18)
...: sch_day.addValue(openstudio.Time(0, 16, 0), 20)
...: sch_day.addValue(openstudio.Time(0, 24, 0), 18)
In [7]: print(sch_day)
OS:Schedule:Day,
{91357986-488a-469e-8dca-cd87a7647e4b}, !- Handle
Medium Office Cooling Setpoint All Other Days Schedule, !- Name
{1f748523-f5e7-4388-8c2d-3aed545795c2}, !- Schedule Type Limits Name
, !- Interpolate to Timestep

A long time ago i was trying to develop a OSM handler, may be you can try it and modify it to your goals https://github.com/AltamarMx/osm_handler
