Device Integrations
Device Integrations in Home Assistant is designed around Open-source home automation platform for controlling smart devices and tied to measurable business objectives.
Automations
Home Assistant brings Automations into a controlled workflow with roles, approvals and traceable data paths.
Local Control
Local Control can connect to operations, reporting and adjacent systems instead of remaining an isolated function.
Home Assistant Hosting in Germany
WZ-IT designs, deploys and operates Home Assistant for Open-source home automation platform for controlling smart devices - close to the site, securely connected and covered by central monitoring, updates and recovery.
About the technology
What is Home Assistant?
Home Assistant addresses Open-source home automation platform for controlling smart devices. A running application alone is not enough for production: data, identities, integrations, updates and recovery have to be designed as one system.
Scoping focuses on Device Integrations, Automations, Local Control, roles, data paths and recovery. WZ-IT turns these requirements into a documented target architecture and can take responsibility for migration, integration and ongoing managed operations.

As an alternative to managed hosting in the data centre, WZ-IT provides the hardware, configures Home Assistant, and handles hardening, monitoring, updates, backup and technical support. Access can be limited to the internal network or enabled through VPN and existing identities.
View WZ-IT App Node →Sizing and deployment location
Sizing Home Assistant for real usage
User count alone does not determine sizing. Concurrency, data volume, background jobs, integrations and recovery objectives define the required environment.
| Usage profile | Starting point | Decisive factors |
|---|---|---|
| Small production entry | Technical discovery | Users, data, integrations and protection requirements are classified. |
| Several teams or departments | Load and role profile | Concurrency, permissions and background processes are assessed separately. |
| High data or transaction load | Capacity assessment | Growth, I/O, caches and bottlenecks are measured or modelled. |
| Business-critical operations | HA and recovery design | Outage objectives, maintenance windows and restart targets shape the architecture. |
- The calculator is technical guidance. Data volume, high availability, integrations, migration, edition and service level are assessed before a binding proposal.

Licence and edition review
Offering Home Assistant with the appropriate usage rights
The licence has undergone a technical review. Before the proposal, we align edition, functionality, operating model and vendor terms with the concrete use case.
| Licence model | Reviewed on |
|---|---|

- The entry level is a dedicated size XS instance with 2 vCPU, 2 GB RAM, 40 GB NVMe SSD for €99.90; it suits lightweight applications as well as test and development environments. Size S with 2 vCPU, 4 GB RAM, 80 GB NVMe SSD costs €129.90. We check which size Home Assistant needs in production before provisioning. Size M (4 vCPU, 8 GB RAM, 80 GB NVMe SSD) costs an extra €29.90 excl. VAT, L (8 vCPU, 16 GB RAM, 80 GB NVMe SSD) an extra €89.90 excl. VAT and XL (16 vCPU, 32 GB RAM, 80 GB NVMe SSD) an extra €199.90 excl. VAT, each per month. Additional storage costs €4.99 excl. VAT per 50 GB and month.
- No. WZ-IT does not limit the number of users. How many users can work smoothly at the same time depends on usage and the chosen instance size XS to XL.
- Home Assistant Hosting can be cancelled monthly, with no minimum term and 30 days' notice to the end of the month.
- Germany and Switzerland are available at the same prices, in both cases without US clouds. The data centres are ISO 27001 certified; in Germany we additionally operate with a German provider whose data centres are BSI C5 attested. The Section 203 Managed Cloud for professional-secrecy holders is available in Germany only.
- We typically provide a production instance within a few business days after signing. For a trial, we set up a test instance, usually on the next business day; it runs free of charge for 7 days and without payment details.
- Yes. One .de domain is included with every hosting plan. Alternatively, connect your own domain or subdomain with a CNAME record.
- Depending on scope, we cover target architecture, deployment, secure baseline configuration, monitoring, backups, updates, recovery, documentation and technical incident handling. Integrations and further development can be added.
- Yes. Before takeover we assess version, edition, data, extensions, identities, integrations, backup status and known legacy issues, then define a controlled takeover or migration plan.
- At the review date of this page, Apache-2.0 was identified. Before deployment we verify the concrete version and edition again and document the applicable licence source.
- Depending on protection requirements and data paths, it can run on dedicated WZ-IT infrastructure, in your cloud, on premises or as a hybrid setup. The target architecture is agreed in advance.
- Typical integrations include MQTT, OPC UA, Modbus, LoRaWAN, REST, time-series databases, Grafana and ERP or MES. Protocols and device lifecycle are assessed per location.
Reviews & projects
Client feedback and projects worldwide
WZ-IT moved our studio infrastructure from decentralised individual devices to a central platform: every site is securely connected via VPN, new devices are onboarded automatically and an entire site is provisioned from a template, without manual steps on location. What impressed me most is the breadth and depth of their knowledge: Timo and Robin are not a typical IT provider who sets up a server and leaves. The two of them think their way into highly complex infrastructure and software topics, work through every requirement we put in front of them, and build networking, provisioning and operations so that everything fits together in the end. WZ-IT is an excellent partner for complex software, network and architecture projects.
