Export and Import

Export and Import

Back up a device, move it to another Home Assistant install, or copy a single program. Everything is under Advanced > Diagnostics > Export / Import and needs a Home Assistant administrator. One file holds one device.

Exports are compact: about 2 MB for a large install.

Back up a device

Press Quick export everything. The file holds all of the device's data: programs, every cycle with its power trace, phase maps, groups, settings, ML models and lifetime totals. Take one before an experiment.

Export only some data

Press Export (choose data) and tick what to include:

Category	Pick
Profiles (programs)	per program
Cycles (run history)	per cycle, grouped by program
Reference cycles (imported) (from the store)	per cycle
Cycles found in imported power history	per cycle
Custom phases, Profile groups	on / off
Detection & matching settings, ML models	on / off
Feedback & review labels, Suggestions	on / off
Maintenance log, History & change logs, Lifetime totals	on / off

A program exported without its cycles still matches. Phase ranges travel with their program. Detection & matching settings here means the thresholds only, without Off Delay, Minimum Off Gap or other plug timing; Quick export carries every setting.

Import

1. Press Import from JSON, load the file (or paste its JSON) and press Analyze file. Nothing changes yet.
2. Tick what to import.
3. Choose:
   • How to combine: Merge (keep mine) adds items and loses nothing, or Replace selected wipes and refills only the ticked categories.
   • Where should imported cycles go?: Reference (shape only) (default) helps matching but never counts in your statistics. Real history (counts in stats) is for moving an appliance to a new install.
   • Name clashes (Merge only), per program: Import as copy (default, "Cotton 40" arrives as "Cotton 40 (imported)"), Keep mine or Overwrite.
4. Press Import selected.

Good to know:

• An import never changes this device's power sensor, door sensor, switch or other linked entities. Set those on the target device yourself.
• A file from a different appliance type imports programs and cycles as reference data only. Settings, ML models, power-history cycles and real history are greyed out.
• HA diagnostics files work too (Settings > Devices & services > WashData > your device > Download diagnostics), so the file you attach to a bug report doubles as a transfer file.

Undo an import

Before a Replace selected import, an Overwrite of a program, or an import_config service call, WashData saves a restore point. Undo last import (administrators) then puts the device's programs, cycles and settings back as they were. Only the last import can be undone, and cycles recorded since then are lost.

Services

Both are administrator-only.

Service	Does
ha_washdata.export_config	Writes the device's full export to path, or to /config/ha_washdata_export_<entry_id>.json if you give none.
ha_washdata.import_config	Replaces the device's data with the file at path, like a full restore. Can be undone in the panel.

A path must be in a folder Home Assistant allows (allowlist_external_dirs). Avoid /config/www: files there are public.
