SOTI Connect System Requirements

To install and operate SOTI Connect, your system must meet the following minimum hardware, software, and network requirements.

On-Premise Installation (Complete System)

This section outlines the essential requirements for deploying SOTI Connect in an on-premises environment.


Component	Requirements
Operating Systems	Windows 10 (Anniversary Update or later) Windows 11 Windows Server 2016 Windows Server 2019 Windows Server 2022 Note: SOTI recommends using Windows 10 for testing and non-production environments.
Hardware Requirements	Minimum dual-core processor Minimum 8 GB RAM
User Privileges	Administrator privileges are required for installation.
Required Software	.NET 8 Runtime ASP.NET Core Runtime 8
Installer Dependencies	UI Installer: .NET 8 Desktop Runtime (includes .NET 8 Runtime) and ASP.NET Core Runtime 8 Silent Installer: .NET 8 Runtime and ASP.NET Core Runtime 8 Troubleshooting: If installing SOTI Connect using `SilentInstaller.exe` and .NET 8 is not detected, the installation will stop without an error message. To resolve this issue, install .NET 8 manually and re-run the installer.
SQL Server	SQL Server 2022 Note: Starting with SOTI Connect version 2025.0.2, SOTI fully supports SQL Server 2022. For SOTI Connect versions 2025.0 and 2025.0.1, SOTI recommends continuing with SQL Server 2019. Tests indicate minimal performance benefits for often used queries when using SQL Server 2022, and significant drawbacks for some queries. SQL Server 2019 and SQL Server 2019 Express SQL Server 2017 and SQL Server 2017 Express Note: Set data truncation to 6 GB maximum for environments using SQL Express. Database mirroring is not supported.
SQL Permissions	A SQL Server user must have permissions to create, modify, and drop databases. Required permissions vary by installation type: Standard operations: Requires `db_owner` privilege. New installation or upgrade: Requires `Sysadmin` privilege. The SA account is a super admin account with all the needed permissions for any scenario. Service running as Local System (DB on same server): The computer runs the service under the Local System > NT AUTHORITY\System account. This needs `Sysadmin` permissions during an upgrade. Service running as Local System (DB on remote server): The service runs under the account `MachineName$`, defined as `domainname\computername`. Using Microsoft SQL Server, add the user or the group containing the user to the `db_owner` role. Service running under service account: Make sure the user account (for example, `samplecompany/ConnectMDM`) has the required permissions in the DB to run the service. Tip: Install databases on a separate machine (server or VM) for optimal performance.
SOTI Connect Installer	Download the SOTI Connect Installer.
Firewall and Port Requirements	Your IT policies should allow a local administrator to open required ports. If using the MQTT protocol, use a commercial-grade MQTT broker such as HiveMQ. SOTI recommends installing HiveMQ on a separate machine for optimal performance.
Required Network Ports	A full installation of SOTI Connect uses many communication ports. The installer automatically adds Windows Firewall rules for required ports. You may need to manually open the following ports: 443: Web Access Note: SOTI Connect and SOTI MobiControl both require the use of port 443. Due to this, you cannot install both products on the same machine. 1234: Logging Service 1433: SQL Server Engine 1883: MQTT Server 4610: Simulator—Homecomfort 4611: Simulator—Hue 4646: File Store 4649: Management Server 4650: File Store Service 4651: Management Server Cluster 5551: WebHook Receiver 8883: MQTT Broker For more information on SOTI Connect network port requirements, see Network Ports.
SOTI Services	SOTI Services includes the Activation Service, Notification Service, and Location Service. These services provide your SOTI Connect deployment with: License updates Device type definition updates Device location capabilities Access all SOTI Services using HTTPS on port 443. Whitelist the following fully qualified domain names and IP addresses with your firewall to enable unrestricted communication between your SOTI Connect installation and the SOTI data center. Note: To download or update device type definitions, the SOTI Connect management service requires access to the following URL endpoints: notificationservice.soti.net and downloads.soti.net.
IP Addresses to Whitelist	SOTI Services are load-balanced across the following IP addresses: 13.248.157.19 54.208.149.103 54.208.194.169 54.209.62.205 54.209.186.178 54.209.186.251 54.209.207.237 75.2.25.8 76.223.23.230 99.83.149.241
Browser Support	SOTI recommends using the latest version of the browser. Use one of the following supported browsers to access the SOTI Connect Console: Google Chrome Microsoft Edge Note: SOTI Connect supports resolutions up to 960 x 720. Although the supported browsers support the use of tablets and smart phones, The SOTI Connect UI is not optimized for these devices.
Certified Device List	To view supported devices, see the Certified Device List for SOTI Connect. If your device is not listed, contact your SOTI Account Manager or SOTI Support.

Optimizing Your SOTI Connect Environment

SOTI recommends the following practices to make sure your SOTI Connect environment is optimally configured:

Schedule antivirus and malware scans on the virtual machine (VM) during periods of low system load to minimize performance impact.

For deployments managing over 10,000 devices, SOTI recommends upgrading to an environment equivalent to an Azure B4MS instance.

All-in-One Configuration Reference

Use the table below as a reference to configure your All-in-One SOTI Connect 2025.0 deployment:


Devices	Azure Instance Type	SQL Edition	Data Truncation	HiveMQ Heap Size	Queue Size

10K—50K	B4MS	SQL Server 2019 Enterprise or Developer	2x default	8 GB	200K max

Note: When device check-in and file download occur simultaneously, the system must handle no more than 10,000 devices and perform no more than 2,500 downloads concurrently. The file size is not relevant.
