Loxone has released a critical security update for the Miniserver, version 17.3.11.10, and asks every owner to install it straight away. 1Install offers a Loxone Miniserver update service across Ireland: we back up your system, install the update, check your remote access and passwords, and leave everything working.
If your home or building runs on Loxone, now is the time to act. This page explains what has happened, what the update fixes and what changes on 1 December 2026, and how we can do it for you. To book, fill in the contact form at the bottom of this page.
Why a Loxone Miniserver update is urgent
On 10 November 2026 Loxone published a critical security update for the Miniserver. Loxone says it found a vulnerability that allows repeated restarts of the Miniserver to be triggered over the network, which can affect how the Miniserver runs. Version 17.3.11.10 protects against it. The update is free and Loxone recommends updating all Miniservers immediately.
As a precaution, Loxone has also made the Miniserver web interface unavailable through Remote Connect until further notice. The Loxone App and Loxone Config still work remotely as usual, and everything keeps working on the local network.
The Loxone cyberattack in October 2026
The update follows a cyberattack on Loxone itself. Loxone detected an attack on its internal company systems on 18 October 2026. It says the Miniserver, Remote Connect and Exosphere were not affected, because a Miniserver runs locally with its own user accounts. Loxone's management did tell the Austrian broadcaster ORF that customer data was taken, and Loxone has said the data mainly covers partner contact details, support requests and job applicants.
For owners, the practical risks are convincing phishing emails and old passwords. If your Miniserver password was ever sent to Loxone or to an installer in an email or a support request, it should be changed. Loxone will never ask for your password by email, phone or text message.
Remote Connect needs an up to date Miniserver from 1 December 2026
Loxone has also announced that its free Remote Connect service will require Miniserver version 17.2.10.21 or later from 1 December 2026. After that, each new Miniserver release gives four weeks to update before Remote Connect requires it. A Miniserver left on an older version will lose Remote Connect, and with it Loxone Cloud DNS, so the app would only reach it from outside the house through port forwarding or a VPN. Keeping the Miniserver updated is now the only way to keep the simple remote access of Remote Connect.
What our Loxone Miniserver update service includes
- A full backup first. Loxone notes that its automatic update does not create a backup, so we save your configuration before anything changes.
- The update to 17.3.11.10, or the current release, using Loxone Config, with a check that every Extension and device comes back online.
- Remote access checked. We confirm Remote Connect works and close any port forwarding that is no longer needed.
- Passwords and users tidied. New administrator password, old accounts removed, and a separate time limited user for service visits instead of sharing the admin login.
- Two factor authentication set up where your version supports it.
- A short report of the version installed and what we changed, kept in your client portal.
Remote or on site
Where we can reach your Miniserver safely we can often do the update remotely, charged as remote support at €110 an hour plus VAT. Where a visit is needed, for example an older Miniserver, a failed update or a house with no working remote access, a visit is €440 plus VAT for up to 4 hours, as set out in our smart home cost guide. We tell you which applies before we start.

Questions we are often asked
Is my Loxone house at risk right now?
Loxone says the Miniservers in homes were not affected by the attack on its own systems. The vulnerability fixed in 17.3.11.10 is separate and can cause repeated restarts over the network, which is why Loxone asks everyone to update now.
Can I update the Miniserver myself?
Yes, with Loxone Config or the Loxone App if you have the administrator login. Back up first. If you do not have the login, or the update fails, we can help.
Our original installer has gone out of business. Can you help?
Yes. We take over systems installed by others. If nobody has the login details, we identify the Miniserver on site and restore access, then update it.
Do you look after Loxone after the update?
Yes. Remote Connect now allows four weeks for each new release, so we can keep your Miniserver current under 1Install Care.
