Internet gateway hub Termojet EGW100WF

Termojet EGW-100 — a hub-gateway that connects wireless devices operating at 868 MHz to the home Wi-Fi network and the Smart Life/Tuya cloud. The internal 868 MHz radio protocol ensures stable communication with devices inside the building; the external 2.4 GHz Wi-Fi transmits data to the internet for remote access. Powered from the AC 230 V mains.

Technical Specifications

Operating Principle

The EGW-100 acts as a translator between two protocols: devices operating at 868 MHz (primarily the thermostatic head TRH-10) send signals to the hub via radio channel — the hub forwards them to the Smart Life cloud via Wi-Fi and vice versa. Once the EGW-100 is connected to the network and Smart Life, all devices paired with it become available in the app: schedules, scenarios, remote temperature monitoring, and setpoint adjustments. Voice commands for Google Assistant and Amazon Alexa arrive through the same Tuya ecosystem.

Which Devices Require the EGW-100

• Thermostatic head TRH-10 — mandatory. The TRH-10 controls the radiator valve independently, but it requires the EGW-100 hub to connect to Smart Life and enable remote control. Without the hub, the thermostatic head operates in manual mode only.
• Thermostat WT-150 — optional. The WT-150 connects to the receiver R06 or the control centre TJ-03-RF, which provide the Smart Life connection themselves.

Applications

• Smart radiator control. EGW-100 + several TRH-10 heads on radiators — independent temperature regulation in each room without running cables or installing a switching centre.
• Centralised Smart Life hub. If you have several Termojet devices operating at 868 MHz, a single EGW-100 unites them all in one application.
• Voice control for heating. Once the EGW-100 is connected to Alexa or Google Home, commands such as "set the temperature to 22 degrees in the bedroom" are executed without a smartphone.
• Remote monitoring. View the temperature and status of every connected device from anywhere in the world via Smart Life.

Advantages of the EGW-100

• Single connection point to Smart Life for all 868 MHz devices.
• 100 m range — covers the entire building from one connection point.
• Mains-powered at 230 V — always ready, no batteries required.
• Compatible with Google Assistant and Amazon Alexa via Tuya with no additional configuration.
• Centralised scenarios and schedules — programme the entire system in one application.

EGW-100 and Heat Pump

In systems combining a heat pump with radiator heating, the EGW-100 hub paired with TRH-10 thermostatic heads allows different temperatures to be maintained in each room without installing a switching centre. The heat pump receives a precise heat demand signal from the zones where heat is genuinely needed. For more information about heat pump solutions, visit tjheatpump.com.ua.

Frequently Asked Questions

How many TRH-10 thermostatic heads can be connected to one EGW-100?
The manual does not specify an exact limit — in practice the hub supports the standard number of Tuya sub-devices within a single Smart Life account. For a typical private home (6–10 radiators), one EGW-100 is sufficient.

Does the EGW-100 replace the TJ-03-C or TJ-03-RF switching centre?
No. The EGW-100 is exclusively a gateway for connecting to the internet and Smart Life. It does not control underfloor heating actuators and has no boiler output. For zone control of underfloor heating, the TJ-03-C (wired) or TJ-03-RF (wireless) is required.
