Telkonet’s patented powerline communications (PLC) systems – the Telkonet iWire System and next generation 200 Mbps Telkonet Series 5 – use a building’s existing internal electrical wiring to enable Internet connectivity throughout an entire building, converting electrical outlets into high-speed data ports. This is an ideal solution for properties that are not wired with CAT-5 or where CAT-5 is cost-prohibitive.

The EthoStream Gateway Server (EGS) product line of gateway devices, which are developed in-house, deliver wired or wireless high-speed Internet access, integrating easily with any combination of WAN connections. The EGS products range from a cost-effective gateway for limited use applications to a feature-rich, dual-WAN, scalable gateway for full-service properties.

Telkonet’s energy management systems, Telkonet SmartEnergy (TSE) and Networked Telkonet SmartEnergy (NTSE), reduce in-room energy consumption by controlling heating, ventilation and air conditioning (HVAC) usage based on occupancy. By eliminating unnecessary heating and cooling of vacant rooms, TSE typically reduces energy consumption by 30% or greater.

Telkonet’s proactive support center brings quality of service to a new level with its dedicated, in-house employees, 24/7/365 support, and integrated proactive monitoring and management tools that put property management in control. By integrating the EthoStream Gateway Server and the web-based Telkonet CENTRAL, our in-house support team has real-time visibility into a property’s HSIA usage and data, as well as ISP status.

Energy Management

Hospitality Savings

Telkonet SmartEnergy™ (TSE) controls HVAC usage and improves energy efficiency by adjusting and maintaining a room’s temperature based on occupancy, using a combination of occupancy sensors, intelligent programmable thermostats or packaged terminal air conditioner (PTAC) controllers. TSE eliminates wasteful heating and cooling of vacant rooms without compromising an occupant’s comfort based on our patented Recovery Time™ technology.


Building on the proven capabilities of the TSE system and incorporating Telkonet's unique Recovery Time™ technology, our new Networked Telkonet SmartEnergy (NTSE) advances intelligent HVAC building control with a flexible, resilient and low-cost energy management platform. NTSE utilizes a ZigBee wireless IEE802.15.4 “mesh” network, where each device functions as a wireless repeater and enables energy management thermostats to communicate with each other and aggregate communications up to a single master NTSE Gateway Server on site. NTSE enables central control without needing expensive back-haul wiring. Its key monitoring and analysis features ensure optimum energy savings, giving property owners the tools to identify and implement energy savings, providing total visibility and detailed data about a property's HVAC system and its energy consumption, together with real-time, instant remote management capabilities.

Key features and benefits of NTSE


  • Room occupancy detection – Detects when rooms are unsold, resulting in deeper energy savings
  • Proactive issue response – Detects changes in efficiency and operational effectiveness of HVAC equipment to resolve issues quickly and effectively
  • Remote management – Enables real-time monitoring and management of all NTSE devices via the web-based portal, Telkonet CENTRAL, where management can dynamically control, monitor status, and define rules and events for HVAC system operability, en mass and individually
  • Thermostat Operation Profiles – Enables easy adjustments of profiles via Telkonet CENTRAL, including Default, Maintenance, Unsold, Deep Setback, and Demand Profiles
  • Detailed energy management reports – Measurement and verification (M&V) analysis, including reports for System Efficiency, Occupancy, Savings, System Status, and System Diagnostics
  • Quick, easy access to management energy savings reports, analysis, payback information and ROI
  • Simple integration with Property Management Systems (PMS)
  • Peak demand load shedding
  • Network outage and maintenance alerts

PLC Networking

Telkonet’s proprietary, patented powerline communications (PLC) products harness a building’s internal electrical wiring to form an IP network, turning power outlets into data ports, while leaving the electrical functionality unaffected. Telkonet’s PLC systems – the Telkonet iWire System and the 200 Mbps Telkonet Series 5 – represent a quick, economical, and non-disruptive way to achieve high-speed Internet connectivity throughout a building. Telkonet’s PLC systems offer the hard-wired security and reliability of a CAT-5 cabled network, but without the cost, physical disturbance and business disruption of wiring CAT-5. For properties looking to provide wireless coverage, Telkonet’s systems can be used to feed WiFi access points, which can be connected quickly and simply to any power outlet.


Series 5 Comparison “With 209 sites and limited numbers of IT technicians, we needed a reliable, plug-and-play system that was easy to install, maintain and operate. With Telkonet’s solution, we demonstrated that our own IT staff and contract electricians could install the system…”
Steve Custer, Supervisor CCTV/LAN Networking and A.V. Repair, Hillsborough County School District (SDHC)
