ES/S-A HOTA "Heart of the Appliance" is a open, modular Virtualized Automation System developed on base of the Extensible Services / Server for Automation Platform.
This Automation system was the first member of the newly created ES/S-A Platform, and was subjected to replace the outdated Predecessor TAC "Terminal Automation Controller", that was both technically and schematically inferior.
The ES/S-A Core has been planned extensively in regards to stability, persistency, viability and security. To also serve the technically sensitive subject of public facility automation, the software has been required to pass certain aspects on conventions, reliability and safety. The application is also subjected to certain requirements in engineering that point to it's origins in public applications, the follow-strict escalation sequence is one of these requiements.

Overview
The first version was published early 2017. The predecessor has been phased out completely mid 2017. The first version had poor support for additional abstraction layers and experienced major issues with persistency (state consistency).
The need for constant impovements to usability and interopability led the team of engineers to permanently install the current stable version in a one-of-a-kind research building, to monitor, analyze and improve the system under exceptionally real conditions. By 1.2.08-SN (03/2019) most teething has been eradicated, and the platform maintains scalar performance on all supported platforms, including Windows Server
Technical

- Public Announcements and SIP Calling
- E-Mail Signaling
- Primitive Abstraction Layers (PAL)
- Facility Services
- Primive Data Points
- Complex Objects
- Script Engines (Extensible Object Script)
- Building Model Providers
- Network Cell Presency
- HVAC and Climatization
- Energy Monitoring
- Electric Planning and Lookup
- Fire and Threat Protection
Integrated Modules

- INEGL Protocol, via IP
- KNX Bus IEC 14543-3 via IP, USB, Serial
- ARTNET, via IP, USB
- Modbus RTU/IP, via IP, USB, Serial
- ASHRAE BACnet, via IP
User Interfaces
ES/S-A HOTA runs as command-line output only application. Most of the User interfaces are delivered via HTTP and renderen in a Browser Window. User interface can be serve interactive resources that are either directly accessible or require a middleware.
| User Interface | Type | Audience |
|---|---|---|
| sv_ata | HTML5 (HTTP/S) | Residential focused user interface with support for mobile devices and touch screens, rich animated using extesively graphics elements, fun to use and interact with. Low technical knowledge required. Has many features like Screensavers, News, Weather forecast, Graphs, Visual control, Virtual Tours and more. |
| sv_gna | HTML5 (HTTP/S) | Professional focused user interface with support for multi-screen setups. Technical knowledge required to address all functions. |
| mta | JSON (HTTP/S) | Used for the MicroTaskInvoker application (Native Windows Application). Provides minimal acces to preconfigured functions. |
| cisco | XML (HTTP/S) | Used for Cisco SCCP Telephones to access the system via various Cisco IP Phones. Provides secured access to number and call registers, system shortcuts and control of devices. |
| telnet | TCP/IP | Provides remote control of the system using minimal bandwidth. Has access to many features of the system. Please notice that remote access must be provided by using an encrypted tunnel like IKEv2, because Telnet does not support TLS encryption. |
| esterm | TCP/IP | Provides partial graphical control of the system using text-only transmission utilizing the ESTERM Protocol, can be used with Netroda Technologies NETerm. |
Globalization
ES/S-A HOTA uses English only, the various user interfaces that can be installed have variying international support. sv_ata currently supports 4 languages

Support
Live, Phone and email support for ES/S-A HOTA is available in English, Russian, Spanish, German, Portuguese, and Japanese. SignMatic licenses purchased directly from Netroda Technologies include full free support.
Security
ES/S-A HOTA Supports TLS for the Secure HTTP Service (HTTPS) version 1.3. The web interfaces can be protected from bogon requests, internet access in WAN Networks. Network services feature automatic blacklisting and source-network abuse query. By utilizing FoundationShield or any other Firewall or Network monitor, ES/S-A HOTA can be securely exposed to the internet, following a positive risk assessment concering stability agains Distributed DOS (DDoS) attacks.
The default configuration does neither allow anonymous users, nor default credentials or insecure WAN access to recude the probability of security issues by misconfiguration or negligence.
A zero-day vulnerability involving remote code execution in Log4j 2, (a Logging utility for Java) , given the descriptor CVE-2021-44228, was found and reported to Apache by Alibaba on November 24, 2021, and published in a tweet on December 9, 2021. Investigations proceeded and it was reported to customers, that ES/S-A HOTA is not affected, as Log4j (used by various components) is replaced by the distributed debugging service in release versions.
It is recommended to protect facility systems with at least two firewalls from different vendors or with different software.
