A 1Home server India project usually comes down to three devices: Server KNX Pro, Server CH and Voice & Visu. Server KNX Pro is the full KNX server, Server CH connects KNX to Crestron Home, and Voice & Visu adds voice control and the app to a KNX project. This post sets out what each does, who it suits and what the v5.0 software added, and it replaces our September post on the same question.
This post updates our 19 September post on the same subject. Where the two disagree, this one follows 1Home's own documentation and the Morion 1Home page.
What does a 1Home server do?
1Home is a Slovenian company. Its servers connect an existing KNX system to the apps and platforms people already use, and they run locally on the home network. The 1Home page on morion.in describes them as connecting KNX, Matter and Crestron automation to Apple Home, Google Home, Amazon Alexa, Samsung SmartThings, Home Assistant and Crestron Home, without changing the system underneath.
Which device does what?
The comparison below is taken from the 1Home compare table on our 1Home page. It covers the devices that matter most for a home project.
| Feature | Server KNX Pro | Server CH | Voice & Visu |
|---|---|---|---|
| Main job | Full KNX server for homes of all shapes and sizes | Imports and syncs KNX devices in Crestron Home | Voice control and the app for a KNX project |
| Voice assistants and Matter bridge | Yes, 250 devices | No | Yes, 250 devices |
| 1Home mobile app | Yes | Yes | Yes |
| Scenes | Yes | No | Yes |
| Graphs and charts | Yes | No | Yes |
| Remote ETS programming | Yes | Yes | No |
| KNX to Crestron Home | Yes | Yes | No |
| Matter devices into KNX (Matter controller) | Yes, 100 devices | No | No |
The page also lists the System Manager, a device for integrators who maintain many projects. This post leaves it aside.
What do all of them share?
According to the compare table, the four devices all connect directly to the KNX twisted-pair bus and include a built-in KNX IP interface. They also detect KNX devices automatically from the ETS project, act as a KNX time server, and run fully local. Each has remote dashboard access, remote management of several projects, configuration backup and a history of events. So the choice is not about whether KNX works. It is about which platforms you want KNX to reach and which tools your integrator needs.
Two limits are worth knowing before you plan. Voice control and the Matter bridge list a limit of 250 devices, and Matter devices brought into KNX list a limit of 100. A very large house should check its device count against these figures.
Who is each one for?
- Server KNX Pro suits a home that wants one box for voice, the app, scenes, graphs and remote support, including Matter devices that sit alongside KNX.
- Server CH suits a home whose control system is Crestron Home and that wants its KNX devices to appear there. It is not a Matter bridge, so it does not bring voice control from Apple, Google or Alexa.
- Voice & Visu suits a KNX home that wants voice control and the app, and does not need remote ETS programming or the Matter controller.
If you cannot decide, the useful question is what the household already uses. If it already has Crestron Home, CH is the natural fit. If people ask for Siri, Google or Alexa, you need a Matter bridge, which means Server KNX Pro or Voice & Visu.
What did the v5.0 software add?
1Home released version 5.0.0 on 19 November 2025. Its release notes list, among other things:
- Graphs. Plot a thermostat setpoint against the actual temperature over time, or build graphs for KNX group addresses.
- Traffic Monitor. A history of group events on the KNX bus and on the 1Home device, and the ability to send a group event from the dashboard.
- A Lua scripting block in Automations, for custom scripts that work with 1Home devices, the KNX bus and HTTP or HTTPS endpoints.
- KNX Remote Access v2. Redesigned for security, reliability and speed, with dedicated cloud infrastructure for the Asia-Pacific region.
The notes do not say which feature belongs to which device. The compare table above shows what each device includes, and Graphs, for example, is not on Server CH. Ask us to confirm the features you need on the model you choose.
What is coming next?
The 1Home page marks three features as coming soon: advanced email alerting, KNX Data Secure support and automatic health checks of the installation. 1Home lists automatic health checks and advanced email alerting for late 2026. We will update this post when a date is confirmed. Until then, treat these as later this year and not as something to plan a project around.
What is not in the box?
1Home's DIN-rail devices share one housing, four modules or 72 mm wide, with Gigabit Ethernet. The power supply and the network cable are not included, so put both on the quote. Pricing is quoted per project, based on the device list.
Questions people ask
Does Server CH work with Apple Home, Google Home and Alexa?
No. Server CH is for KNX in Crestron Home and is not a Matter bridge. For voice control from those platforms, look at Server KNX Pro or Voice & Visu.
Do the servers need the internet?
No. 1Home says its servers run locally. Remote access and voice assistants use a secure connection or cloud service, so those parts need internet.
Why does this post differ from your September post?
We checked the earlier post against 1Home's documentation and the Morion 1Home page and found it described Server CH incorrectly. This post follows the documentation.
