In the scene editor, building a long scene means rebuilding the same block over and over: the same "If Then Else" block six times in a row, or the same "control a device" action for each room/heater/light. This PR adds a duplicate button in the header of an action block, which inserts a copy of the block right after the source block (not at the end of the scene), so the user only has to change the device instead of recreating everything.
What was implemented:
A Duplicate this block button (fe fe-copy, same icon as the existing "duplicate scene" button) in the header of an action block, next to the existing delete button.
It is available on root-level blocks and on the blocks nested in a then / else branch of an If Then Else / While action — so an If Then Else action with many actions inside is duplicated along with its block.
It is not displayed on blocks where it makes no sense, as discussed on the forum:
the empty block at the end of a list (nothing to duplicate, it is the "add" drop zone),
the conditions section of an If Then Else action, which can only exist once.
The scene variables follow the duplication: variables of the blocks located after the copy are shifted by one index, the variables of the duplicated block are copied for the new block, and references to those variables (in texts like {{1.0.last_value}} and in only continue if conditions) are rewritten accordingly — the same way the existing "insert an action group" feature does it.
The path-rewriting logic that was inlined in addActionGroupAfter has been extracted into a shared replaceVariablePathInActions helper, now used by both the insert and the duplicate code paths (no behaviour change for the existing feature).
Files touched (front only, no server change):
front/src/routes/scene/edit-scene/index.js — new duplicateActionGroup(path) state handler + extracted helper
front/src/routes/scene/edit-scene/ActionGroup.jsx — the duplicate button
front/src/routes/scene/edit-scene/EditScenePage.jsx, ActionCard.jsx, actions/ConditionIfElseThen.jsx, actions/ConditionWhile.jsx — prop plumbing so nested blocks get the handler
front/src/config/i18n/{en,fr,de}.json — new editScene.duplicateActionGroupButton key in all three languages
Linter and prettier pass on both front and server (npm run eslint, npm run prettier) — front only was modified: npm run prettier, npm run prettier-check, npm run eslint (0 errors), npm run compare-translations (no errors), npm run build (OK)
No undocumented breaking change
Tests pass: cd server && npm run coverage — not run, no server file is modified by this PR. Cypress was not run locally (no browser available in the environment); the existing scene spec targets buttons by their i18n text and the new button is icon-only, so it should not be impacted.
Note: this pull request was opened by an automated Claude Code run. The duplication logic was exercised with a small local harness (root-level block, block nested in a then branch, block containing an If Then Else), but it still needs a human review and a real click-through in the scene editor before merging.
In the scene editor, users building long scenes have to rebuild the same
block of actions over and over (same "If Then Else" block, same "control
a device" action per room).
This adds a duplicate button in the header of every action block that
contains at least one action, at the root level of the scene as well as
in the blocks nested in a "then"/"else" branch. The copy is inserted
right after the source block, so the user only has to tweak the device.
The button is not displayed on the empty block at the end of a list (there
is nothing to duplicate) nor on the conditions section of an "If Then
Else" action, which can only exist once.
The variables of the scene follow the duplication: the variables of the
blocks located after the copy are shifted by one, the variables of the
duplicated block are copied, and the references to those variables
(in texts and in conditions) are updated accordingly. The code doing that
rewriting was extracted from addActionGroupAfter into a shared helper.

Duplicating nested scene blocks may use stale scene state and overwrite the newly inserted copy, potentially leaving actions or variable references incorrect. This bounded editor-correctness risk should be fixed or explicitly accepted before merging.

A rabbit duplicates a block with care,
Paths and variables follow it there.
Three languages label the button bright,
Nested groups copy just right.
Hop, click, and the new block takes flight.

Verdict: request changes
Front-only scene-editor UX that matches the forum request: duplicate button on action blocks (root and nested then/else), not on the trailing empty group and not on the If/While conditions list; copy is inserted immediately after the source. i18n is in EN/FR/DE. Prop plumbing through ActionCard → If-Then-Else / While is complete. CI is green (Front test/build, Cypress, Server, Docker).
Not ready to merge: the new duplicateActionGroup path can silently rewrite the wrong variable references when saving the scene.
Blockers
Unanchored path replace in replaceVariablePathInActions (now shared with insert). conditions[].variable values like 11.0.last_value match substring 1.0 and become 12.0.last_value. That is the realistic outcome of this feature (many duplicated If-Then-Else blocks). A global split(prevPath).join(newPath) would make it worse — use a real path-prefix match for variable, and the existing {{path. form (globally) for templates/evaluate_value.
First occurrence only on the cloned block. A duplicated message/formula with two {{0.0.last_value}} tokens keeps one pointing at the original group. Process duplicate keys longest-first as well, so nested If/While paths cannot be corrupted by a later parent replace.
Residuals (non-blocking)
In-place mutation of prevState.scene.actions is the same pattern as addActionGroupAfter; still an anti-pattern, but not new.
Copied variables[newPath] shares the array reference until the cloned cards remount and call setVariables; $set/spread replacement makes this OK in practice.
No Cypress coverage of the new icon-only button (existing spec targets editScene.duplicateButton text for scene duplicate, so it should not break — and did not, Cypress is green).
German string is fine; no DEVICE_FEATURE_* changes.
Classification
Not risk:high: editor-only, no server/runtime/auth/DB.
needs:human-review: scene-editor variable paths are easy to get subtly wrong; author is Pierre-Gilles → requesting atrovato. A real click-through (root block, nested then, If-Then-Else with inner get-value + only-continue-if, 10+ groups) is still needed before merge, as the PR description notes.
Replace every reference to a variable path instead of only the first one, and
anchor the match on the path so a group index is never matched inside a longer
one ("1.0" no longer matches "11.0.last_value" nor the number "10.05").
The "conditions[].variable" attribute holds a raw path, the other attributes
hold texts or formulas where the variables are wrapped in double curly braces:
they are now rewritten by two dedicated helpers instead of a single unanchored
replace. Anchoring also makes the rewriting independent of the order in which
the variable paths are processed, so a nested path rewritten before its parent
no longer rewrites the parent twice.
Autofix-Pass: 1
Wait for the Preact state commit before repairing empty groups.
preact is locked to 10.25.4. Its setState method schedules rendering and does not return a promise. If a duplicated then or else branch needs a trailing empty group, addEmptyActionGroupIfNeeded() reads the old state and can overwrite the queued duplication. Await a setState completion callback, or combine both updates in one transaction.

Follow-up 0dcbdb9 addresses both previous blockers. Front-only scene-editor UX that matches the forum request: duplicate on action blocks (root and nested then/else), hidden on the trailing empty group and on the If/While conditions list, copy inserted immediately after the source. i18n is in EN/FR/DE. Prop plumbing through ActionCard → If-Then-Else / While is complete. CI is green on this SHA (Front test/build, Cypress, Server, Docker, codecov).
Previous blockers — fixed
Unanchored conditions[].variable replace. Split into replaceVariablePathInRawPath (exact or prevPath. prefix) vs replaceVariablePathInText (global {{prevPath.). 11.0.last_value is no longer rewritten when shifting 1.0, and {{1.0.last_value}} + 10.05 keeps the literal. CodeRabbit's split(prevPath).join(newPath) on the raw path was correctly declined.
First-only String#replace + rewrite order. Templates are rewritten globally. Prefix-safe matching makes nested 0.0.then.0.0 vs parent 0.0 independent of Object.keys order — both orders converge.
Verified against the previous cases (11.0 vs 1.0, 10.0 vs 1.0, double {{…}}, formula 10.05, nested If path both rewrite orders).
The same helper is now used by addActionGroupAfter, so insert also gains the safer rewrite.
Residuals (non-blocking)
In-place mutation of prevState.scene.actions is the same pattern as insert.
Copied variables[newPath] shares the array reference until the cloned cards remount and call setVariables.
No Cypress coverage of the new icon-only button (existing spec targets editScene.duplicateButton text for scene duplicate; Cypress is green). A click on button[title=…duplicateActionGroupButton] remains a good follow-up.
Merge with #2907: both PRs extract path-rewrite helpers in edit-scene/index.js and touch ActionGroup.jsx. Keep this PR's RAW vs text split; reuse it from delete rather than re-inlining the old unanchored replace.

Resolve the conflicts with the variable-path rewriting refactor and the
action group delete button that landed on master:
- ActionGroup.jsx: keep the new duplicate button, and take master's delete
button condition (`firstActionGroup` was removed from the prop plumbing
on master, only `lastActionGroup` is used now).
- index.js: master extracted its own `replaceVariablePathsInActions` helper,
which applies a batch of replacements and already handles both the texts
containing `{{...}}` variables and the raw variable selectors. It
supersedes the single-replacement `replaceVariablePathInActions` helper
this branch had added, so that one is dropped and `duplicateActionGroup`
now calls the master helper, keeping the ordering it documents (the
variables shifted by the insertion are still rewritten from the highest
index to the lowest).

Merge conflicts with master are resolved and pushed (b41be27).
Two files conflicted:
ActionGroup.jsx — kept the new duplicate button, and took master's delete button condition. Master dropped the firstActionGroup prop, so the condition is now just !props.lastActionGroup.
index.js — master extracted its own replaceVariablePathsInActions helper, which takes a batch of replacements and already handles both texts containing {{...}} variables and raw variable selectors. It supersedes the single-replacement replaceVariablePathInActions helper this branch had added, so I dropped this branch's helper (along with replaceVariablePathInRawPath and RAW_VARIABLE_PATH_ATTRIBUTES, now unused) and pointed duplicateActionGroup at master's helper. The rewrite ordering master documents is preserved: the variables shifted by the insertion are still applied from the highest index to the lowest, so a path is never rewritten twice.
Note for reviewers: the PR description still mentions extracting a replaceVariablePathInActions helper — that part of the diff is gone now, the branch just reuses master's equivalent.

Re-review after b41be27 (merge of master to resolve conflicts). Front-only scene-editor UX that still matches the forum request: duplicate on action blocks (root and nested then/else), hidden on the trailing empty group and on the If/While conditions list, copy inserted immediately after the source. i18n is in EN/FR/DE.

Merge with master — looks correct
Two files conflicted; both resolutions are the ones I would have picked:
ActionGroup.jsx keeps the new duplicate button and takes master's delete condition (!lastActionGroup after #2907 dropped firstActionGroup).
index.js drops this branch's single-replacement helper and calls master's replaceVariablePathsInActions (batch, prefix-safe selector + global {{path. text). Shift replacements are still applied highest-index-first so a path is not rewritten twice. Previous blockers stay fixed: 11.0.last_value is not rewritten when shifting 1.0, {{1.0.last_value}} + 10.05 keeps the literal, and a duplicated text with two {{…}} tokens remaps both.
Verified the merged duplicateActionGroup against the earlier cases (root copy with double refs, 12-group 1.0 vs 11.0 shift, nested then/else, If-Then-Else with inner get-value + only-continue-if, nested rewrite order both ways).
CodeRabbit's "stale this.state / addEmptyActionGroupIfNeeded overwrites the copy" note is the same pattern as addAction. await this.setState(...) yields a microtask; Preact's render is queued first, so the duplication is flushed before empty groups are repaired. Not a blocker.
Residuals (non-blocking)
In-place mutation of prevState.scene.actions is the same pattern as insert/delete.

In the scene editor, building a long scene means rebuilding the same block over and over: the same "If Then Else" block six times in a row, or the same "control a device" action for each room/heater/light. This PR adds a duplicate button in the header of an action block, which inserts a copy of the block right after the source block (not at the end of the scene), so the user only has to change the device instead of recreating everything.
