C6/C6M ventilation unit
The power changed
Komfovent C6M
Fresh air, without the fuss.
Warning! This app might not work properly.
This app version is currently being tested, and has not yet been reviewed. It might not work as expected.
Be extra careful when installing this app.
Bring your Komfovent DOMEKT ventilation into Homey. Change modes, build everyday routines with Flow, and keep an eye on power use, air quality and room temperature. See the wall-panel reading alongside the active temperature target, or change a saved profile's target with Flow. Choose Mini, Compact or Advanced for your Dashboard. Everything runs over your local network, without a Komfovent cloud account.
You need Homey Pro and a compatible C6M controller with Modbus TCP enabled. Readings depend on your unit and sensors. Advanced controls and optional room-sensor automation need separate setup. Temperature targets do not force heating on; CAV control is experimental and needs checking on your unit. This is an independent community app, not an official Komfovent app.

C6/C6M ventilation unit
The power meter changed
C6/C6M ventilation unit
The generic alarm turned on
C6/C6M ventilation unit
The generic alarm turned off
C6/C6M ventilation unit
Active airflow target changed
Observed supply/extract targets of the active standard profile, not actual fan speed. Includes %, m³/h or l/s. No initial or reconnect event.
C6/C6M ventilation unit
Control failed
C6/C6M ventilation unit
Actual fan level changed
Measured rounded average of supply and extract fans, not a mode command. No initial, restart or reconnect events.
C6/C6M ventilation unit
Filter remaining reached or fell below Remaining threshold % %
Fires on a downward crossing, including skipped exact values. Replacement rearms it. No initial/reconnect events.
C6/C6M ventilation unit
Operating mode changed
Fires once for a confirmed observed change, including panel/external changes and special modes. Not on initial polling, reconnect or restart. Tokens use stable mode IDs such as normal and intensive.
C6/C6M ventilation unit
Active temperature target changed
Observed temperature target of the active standard profile in °C, not room temperature or heater output. Initial samples and control-source changes do not trigger.
C6/C6M ventilation unit
Ventilation unit turned off
Confirmed observed power state. A lost connection never counts as off.
C6/C6M ventilation unit
Ventilation unit turned on
Confirmed observed on/off state, not a mode command. This trigger only observes; on/off control is a separate action with its own setting.

Control is ready
C6/C6M ventilation unit
Fresh measurements are available
Also available for CAV/read-only monitoring. Does not grant control permission.
C6/C6M ventilation unit
Measured fan level Measurement is above Threshold % %
Actual fan percentages, not profile targets. Invalid/stale data returns false.
C6/C6M ventilation unit
Measured fan level Measurement is below Threshold % %
Actual fan percentages, not profile targets. Invalid/stale data returns false.
C6/C6M ventilation unit
Measured air volume Measurement is above Threshold m³/h m³/h
Confirmed CAV only. l/s normalized to m³/h; percent values never treated as volume.
C6/C6M ventilation unit
Measured air volume Measurement is below Threshold m³/h m³/h
Confirmed CAV only. l/s normalized to m³/h; percent values never treated as volume.

C6/C6M ventilation unit
End the holiday period
Beta. Ends an active or planned holiday by replacing its dates with an expired period, using the unit's own clock. Requires holiday scheduling in settings. Profiles, AUTO and microventilation settings are kept. Follow the actual return in the status.
C6/C6M ventilation unit
Report Requested mode because Reason (room and threshold)
Display only: does not change mode. Place before mode conditions/actions on each decision branch. Include room and sensor/threshold. Reports expire after 15 minutes; refresh at least every 5 minutes. Manual selections remain separately identified.
C6/C6M ventilation unit
Set Profile CAV targets to Supply target/Extract target Unit
Stores the target pair together, including intentional imbalance. Requires enabled CAV beta and matching observed units. No automatic return or confirmation of pressure/fireplace safety.
C6/C6M ventilation unit
Schedule holiday from Start date to End date
Beta. Use dates such as 2026-12-20, without a time of day. Maximum 90 days. The end date is the period boundary; confirm the controller's day change. Requires holiday scheduling in settings. Saves native dates without changing AUTO, microventilation frequency or heating. Confirm actual Holiday operation on your unit.
C6/C6M ventilation unit
Set Intensive profile to Supply target/Extract target percent
Writes both Intensive targets atomically with FC16, verifies exact readback and permits a maximum difference of 50 percentage points.
C6/C6M ventilation unit
Set Profile to Target capacity (%)% target capacity and preserve the ratio
Scales both stored targets together, within whole-unit rounding. Not measured fan speed or pressure. Rejected if the ratio cannot be kept within limits.
C6/C6M ventilation unit
Set ventilation to Mode
Changes only to Away, Normal, Intensive or Boost and verifies the exact Modbus readback.
C6/C6M ventilation unit
Set ventilation unit State
Requires on/off control in device settings. Uses and verifies the unit's on/off command. Fans may run on; this is not a mains isolator. Takes over from built-in room demand control.
C6/C6M ventilation unit
Set Profile airflow targets to Supply target/Extract target percent
Stores both targets atomically in the selected profile, verifies exact readback and permits a maximum difference of 50 percentage points.
C6/C6M ventilation unit
Set reheating permission for Profile: Permission
Allowed means the ventilation unit may use electric reheating when heat is needed; it does not force the heater on.
C6/C6M ventilation unit
Set Profile temperature target to Temperature °C
Stores the selected profile's temperature target and checks it on the controller. Requires profile-temperature control in device settings. Does not change ventilation mode, permit heating or set the heater-element temperature. The target applies to supply, extract or room temperature according to the controller's setup.

What’s new
Version 1.9.1 — Adds active-target Flow triggers, on/off control and optional native holiday scheduling with an early-end card. Removes the duplicate fan-slider page while keeping saved profiles and all three widgets. Corrects an old power-trigger hint and CAV control notes; the control code is unchanged from 1.9.0. Holiday remains beta on other firmware and CAV units.
Komfovent C6M
Komfovent C6M is not compatible with the selected Homey.
Komfovent C6M will install on Homey shortly.
