Note:
This post is aimed at users who own Cherubini roller shutters and want to integrate them with Home Assistant. I found little useful info online, so maybe this thread helps you all. Feel free to add your tips or experiences—whether you use Cherubini or just Home Assistant!
Starting Point: New build, standard shutters, no smart home planning
Like many others, we didn’t really think about smart features when building our home. We chose Cherubini shutters mostly because we liked their radio-based controls:
-
Individual adhesive radio wall switches
-
Remote controls, either:
- simple (up to 7 devices)
- „Large“, with scenarios (time‑or week‑based)
-
Optional weather station/wind sensor (mostly useful for awnings, less so for shutters)
First Smart Home Steps: Shelly, Ikea Tradfri & Home Assistant
Our first smart project was automated porch lighting. Berker’s solution was expensive, so we went low‑cost with a Shelly switch—my first real smart‑home setup. Then we added:
- Shellys for lights and switches
- Ikea Tradfri
- Home Assistant
But the roller shutters remained unsolved…
Problem: Rollers not natively smart-home controllable
We wanted solar shading, e.g. halfway down at midday to reduce heat.
But:
- You can’t create enough custom groups via Cherubini remotes for multiple scenarios
- Shellys don’t work, because Cherubini uses one‑wire sequence control: Up → Stop → Down → …
Cherubini released a hub, but it’s:
- Expensive
- Closed‑source
- Not compatible with Home Assistant
Solution: RFXcom + Home Assistant = 
I discovered a great alternative:
RFX-433 with Extended Motor Control
- Supports rolling‑code Cherubini
- Wi‑Fi—place it anywhere
- Integrates with Home Assistant
- Low cost
Installation:
- Problemlos, nur durch eigene Fehler musste ich einmal die Firmware neu flashen.
- Beim Anlernen habe ich versehentlich zwei Rolläden auf denselben Kanal gelegt – war aber leicht zu korrigieren.
Installation was easy (I only reflashed firmware once by mistake). During pairing I accidentally assigned two shutters to the same channel—but that was easy to fix.
Setup steps:
- Install the RFXcom integration in Home Assistant
- Pair each shutter individually using the RFXcom tool
- They were immediately recognized in HA
- Naming and assignment was straightforward
Result: I can now control my Cherubini shutters in a “semi‑smart” way through Home Assistant!
Current Capabilities
Standard Features:
- Control via mobile app
- Automatic down‑slit when sun is high
- Up/down based on sunrise/sunset
- Better signal range than remotes
- Central control of all shutters
Limitation:
- No position feedback—must use time‑based control (e.g., “drive down for 10 seconds”)
Example Automations
1. Grouped control (e.g. south side, upstairs, downstairs)
- Handled via scripts
- Includes repetition and delays so shutters open one by one, triggering around 5 times each
2. Sun‑angle shading
- Triggered by azimuth (sun angle)
- A toggle on the dashboard enables “summer mode”
- Adjustable thresholds per facade
- Shutters move to “slit” position at certain sun angles, and go up again when angle changes
3. Automatic ventilation
- At sunset the night mode triggers and shutters go down
- If a window opens (tilt/full), the associated shutter moves to “slit”
- After a set time, it fully closes again
4. Scenarios
- “Wake Kids”: shutters open slowly over 10 minutes in steps
- “TV Mode”: shutters move to “slit” to reduce glare
- “Fire Safety”: all shutters go up automatically if smoke is detected
- Dashboard: manual control of all shutters; long‑press sets them to “slit”
- More scenes possible: Vacation, Sleep, Energy Saving…
Issue: Shutters occasionally didn’t respond
This was due to the number of radio commands sent.
Tip: Cherubini remotes let you configure repeat count (e.g. 5 signals) — I matched that in RFXcom, and it’s now rock‑solid.

Conclusion
With an RFXcom module you get a cost‑effective, semi‑smart solution for Cherubini shutters integrated into Home Assistant. No position feedback, but a wide range of functions and high flexibility.
