01 — Bus monitor & diagnostics · every platform
Everything you need on the bus.
Every telegram live, your ETS project as plain words, and the whole workshop in expert mode.
Your installation as you have never seen it.
Without expert mode the app stays lean: the values, the telegrams and a check of your installation.
- Overview
- Overview & favourites. Every group address as a card with its current value and a mini history, sorted by the rooms and functions of your project. Charts are saved per installation and get their own section on the overview.
- Telegrams
- Live telegrams. Every telegram with sender, destination, value and anomalies. Search in the title bar, one filter button with counts, read and write values. Writing is an intervention in the installation and is your responsibility.
- Objects
- Rooms & objects. Commands and feedbacks grouped automatically, actuators drawn as DIN-rail devices with channel LEDs.
- Health
- Health. Reads status addresses, reports devices that went silent and checks cycles, values, datapoint types and bus quality. With a PDF report.
- Recordings
- Recordings & history. Record with a name and note; a long press keeps the last 10 seconds. Before a replay, change values, remove telegrams, save as a copy; replay with a timeline per group address, 1–60×. Also long-term history and statistics with an activity heatmap.
- Secure
- KNX Secure & routing. Tunnel over UDP or TCP, routing via multicast, KNX IP Secure and Data Secure with the keyring from ETS.
- Comments
- On telegrams, charts and recordings, with up to three screenshots
- Exports
- One page for everything: telegrams as PDF, CSV and for ETS, reports and a ZIP with everything
- Bug report
- Report a problem: reproduce the fault, tap each time it happens, and the diagnostic package goes to your electrician; opened, it shows findings and hints. For support optionally without names
- Getting started
- Teach in without an ETS project: press a button, name it, done. Without expert mode the live list shows every telegram as a sentence; plus connection help, a status light with weekly report and “Learn KNX”
- Backup
- Everything in one file with its own password, in the apps from version 1.9.1
- Demo
- Demo house to try it without a KNX system
- Languages
- German and English
One switch, and the whole workshop is there.
For commissioning, troubleshooting and handover. Turn expert mode on on the connect screen or at the bottom of the menu; in the Home Assistant add-on it is on from the start. Without it nothing is lost, the tools just stay out of the way. Try every tool in the demo house.
- Bus monitor
- Raw frames with ACK/NAK, repeats and bus load
- Checklist
- Commissioning: a checklist of all status addresses, answers are checked off, PDF report with a signature field
- Diagnostics
- Read status, find programming mode, check addresses, scan lines
- Topology
- Map and topology: who talks to whom, lines, couplers and coupler traffic, tunnels
- Compare
- Bus traffic against the ETS project: what is missing, what is unknown, what never sends; plus the object flags (T, R, C) even without bus traffic
- Charts
- Up to eight addresses, one axis per unit, saved per installation
- Trigger
- Trigger recording for sporadic faults: starts on a value, a fault, a repeat or an unanswered read, with pre-roll
- Send
- Like the ETS group monitor: delayed and cyclic, more datapoint types (text, time, date, colour …), set a datapoint type per address
- Replay
- Play a recording onto the bus: choose addresses, change values, shorten pauses, then confirm explicitly
- Hop count
- Its own column in the live list, a hint on unusual routing counters, installation location next to the sender
- Connection
- Port, tunnel address, connection options and keyring right on the connect screen
- Alarms
- Alarm notifications as soon as an alarm or fault object fires
- Acceptance
- Ring-through with sound acknowledgement and an acceptance report signed on the device
- Fault hunt
- Catch sporadic faults over days, with the KNX box
- Photo docs
- Photos of the distribution board and labels with QR codes, per installation
Soon without Home Assistant too, right at the gateway.
For the building site, the distribution board and the office next to ETS: the same tools as an app on whatever device is in your hand.
- Mobile
- iPhone, iPad and Android
- Desktop
- Mac and Windows, Linux today
- Connection
- Directly to your IP interface or IP router
- On site
- ETS project and recordings live on the device, no internet needed
Your project makes telegrams readable.
Import your ETS project (.knxproj, password-protected too) or the group address CSV export. Busclear picks up names, datapoint types, devices, rooms and links. 1/2/3 becomes “Living room ceiling light – On”.
- 1/2/3
- Living room ceiling light – On On
- 1/2/4
- Living room ceiling light – Status On
- 3/1/10
- Kitchen temperature actual 21.4 °C
- 2/0/7
- Bathroom blind position 35 %
- 4/0/1
- Meter active power 1.82 kW
Straight to your IP interface.
Connects via KNXnet/IP to your IP interface or IP router, KNX Secure included. You need no account, and your installation data only leaves your network if you share it yourself.
- KNXnet/IP
- Tunnelling, routing and KNX Secure
- .knxproj
- ETS projects incl. password-protected ETS6
- 0
- Trackers; no account, project and telegrams stay with you
Your data stays yours.
Busclear works on your network and stores on your devices. We have hardened the systems considerably, and the control stays with you: you need no account, and the app does not send your project, telegrams or keys to anyone on its own. Read the privacy policy
- Local
- Project, telegrams, recordings and keys are on your device, your box or your Home Assistant, not with us. Your ETS project password is not stored
- Tracking
- No analytics or advertising libraries, no tracking
- Encrypted
- From version 1.9.1 the apps encrypt their files with AES-256-GCM, with the key in the system keychain. Without a usable keychain (Linux without libsecret), and for settings such as the gateway, data stays unencrypted; the add-on and the box do not encrypt their files themselves
- App lock
- Optional, with Face ID, fingerprint, Windows Hello, device code or an app password plus recovery key as PDF. It helps if the device falls into the wrong hands, not against malware under your user account
- Backup
- In the apps: everything in one file with its own password, in a format that is openly described. Nobody can reset the password, not even us
- No internet
- The add-on and the box need no internet. Data only goes to destinations you set up yourself
- Network
- The app talks to your gateway and your KNX box. Exception: on Android the QR scanner sends technical data to Google ML Kit, never the camera image
