MOES Zigbee Thermostat for Gas Boilers

Product detailed description

MOES Star Ring smart thermostat for gas boilers with Zigbee 3.0 🔥

MOES ZHT-SR-GC from the Star Ring series is a smart room thermostat for boilers that combines precise temperature control, modern design and convenient remote control. The GC version is designed to control gas and water boilers: it switches the boiler on and off according to the room temperature, so your home is exactly as warm as you want.

Thanks to the Zigbee 3.0 protocol, the thermostat fits into your smart home. Control it from your phone via the MOES, Tuya Smart and Smart Life apps, by voice via Amazon Alexa and Google Assistant, or the classic way on the wall with the rotary knob and touch buttons.

Precise room temperature control

This gas boiler thermostat measures the air temperature with an NTC3950 (10K) sensor with an accuracy of ±1 °C. You can set the target temperature from 5 to 35 °C, and the display shows values from 5 to 99 °C. The boiler only switches on when it is really needed and doesn't overheat your home. Timer accuracy better than 1 % ensures your schedule starts exactly when it should.

The device's own consumption is below 1.5 W, so the Zigbee boiler controller itself will hardly show on your electricity bill. Power-failure memory keeps your settings and resumes where it left off once power returns.

Control from the app, by voice or on the wall

Once paired with a Zigbee gateway, you can see the current temperature in the Tuya Smart, Smart Life or MOES app and change it from anywhere, for example on your way home from work or from holiday. In the app you can create automations and scenes (for example lowering the temperature when everyone leaves the house), and device sharing gives other household members access too.

If you don't want to reach for your phone, just say “Alexa, set the living room to 22 degrees” or use Google Assistant. The rotary knob with touch buttons is always available on the wall. The backlit ring changes colour according to the operating mode, so you can see at a glance whether the boiler is heating. The display supports 9 languages.

A weekly schedule that saves on heating

Every extra degree shows on your gas bill. The programmable boiler thermostat from MOES offers a 5+1+1 mode directly on the device (weekdays, Saturday, Sunday) with 6 time periods per day. According to the manufacturer, the app lets you set up to 48 temperature changes per day. Your home is warm in the morning and evening, while during the day and at night the boiler keeps a lower temperature.

Child lock and safe design

The child lock function locks the wall controls, so children or visitors can't change the temperature by accident. The housing is made of flame-retardant PC + ABS, and the IP20 rating is suitable for normal use in living spaces.

Installation in a standard wall box

The thermostat fits a standard European round wall box with a diameter of 60 mm or a square 86 × 86 mm box. It is powered directly from the 230 V mains (range 95 to 245 V AC), so there are no batteries to change. It controls the boiler via a potential-free contact (dry contact, max. 5 A), which is the standard room thermostat input on most gas boilers. Connection to the boiler should be done by an electrician or boiler service technician according to the wiring diagram in the MOES manual.

The model is also listed as ZHTSRGC or by its full code ZHT-SR-GC-WH-MS (white). This is the GC version for gas and water boilers with a 5 A load. If you have electric underfloor heating, choose the MOES Zigbee Thermostat for Electric Heating 16 A (GB).

Technical specifications

Protocols and compatibility

• Zigbee 3.0 (IEEE 802.15.4): the thermostat has no Wi-Fi and needs a Zigbee gateway (not included) to connect to your network. For the Tuya ecosystem, a good choice is the Nous E15 Zigbee and WiFi Gateway; you'll find more in the Zigbee gateways category.
• Tuya Smart, Smart Life, MOES: full support (remote control, schedule, scenes, device sharing).
• Amazon Alexa and Google Assistant: voice control by linking your Tuya / Smart Life account.
• Apple Home: the thermostat does not support Matter or HomeKit and will not appear directly in Apple Home.
• Home Assistant (Zigbee2MQTT / ZHA) and other hubs: as a Tuya Zigbee device it can usually be paired with your own coordinator, but the range of supported functions depends on the current version of the integration. Before buying, check whether the ZHT-SR model is supported in your version.

You'll find more devices for your network in the Tuya Zigbee products category.
