Durablow TR1003 On/Off Gas Fireplace Remote Kit
The Durablow TR1003 provides wireless remote control to a gas fireplace with an integrated thermostat and timer. Best for buyers who want a straightforward RF solution without a full WiFi setup. It operates within a 20-foot RF range and uses the fireplace’s thermopile for safety signaling, not a separate power supply. The 45°F to 99°F temperature range supports modest temperature adjustments. It includes a wall plate receiver and a 18-inch wiring harness, making installation feasible in standard wall boxes. Suitable for those who prefer a battery-powered remote with LCD readout and a simple timer. Caution: Not a standalone power or ignitor unit; ensure proper wiring or series connection when used as a switch.
Who this is best for: Homeowners seeking a simple, non-WiFi remote control with thermostat capability for Millivolt valves.
Durablow SH3002 Gas Fireplace WiFi Smart Control
Durablow SH3002 is a WiFi-enabled controller designed for Millivolt valves, allowing control via the Smart-Life app and voice assistants. It does not provide power to the valve; it passes voltage from the fireplace thermopile to the valve for safety. This model is ideal for buyers who want remote access from anywhere and schedule-based operation, without purchasing a separate hub. It includes a detachable thermostat and a paired controller box, plus a USB power supply adapter. Use this if you want on-demand adjustment and routine scheduling through a familiar app ecosystem. Caution: Works only with gas fireplaces; ensure compatibility with your specific valve and ignition module.
Who this is best for: Users seeking WiFi-enabled control, simple automation, and app-based scheduling for a gas fireplace.
Durablow SH3002D-RH Dual WiFi Smart Control
This model adds dual-band WiFi (2.4G and 5G) for more robust network compatibility and advanced automation via the Smart-Life app. It supports on/off, timer, thermostat, programmable schedules, and a remote transmitter handset. It’s best for tech-forward buyers who want reliable connectivity, multi-device scenes, and remote control across home networks. Note that it requires pairing with the fireplace’s Millivolt valve and ignition module; it does not supply power to the valve itself. Caution: Some firebox configurations may require careful pairing; verify compatibility before purchase.
Who this is best for: Tech-savvy households needing robust WiFi control, schedules, and voice assistant integration for gas fireplaces.

Honeywell’s RTH9600WF offers ENERGY STAR certification and cloud-based control via WiFi. It supports remote access, flexible programming, and compatibility with major smart-home ecosystems. It’s a strong general thermostat that can integrate with a connected home while managing your heating and cooling system, though the device is a thermostat for the overall system rather than a dedicated gas-fireplace valve controller. Best for buyers seeking energy-tracking capabilities, rebates, and broad app support. Caution: Requires C-wire for full features; not a stand-alone gas-valve controller—verify compatibility with your gas fireplace setup.

It requires careful installation, including checking for power outlets near the fireplace. Best for homeowners who want to combine gas fireplace control with blower management and cross-device automation. Caution: Ensure compatibility with your blower and IPI module before purchase.
Buying Guide: Key Considerations For Smart Gas Fireplace Thermostats
What should I consider before buying a smart thermostat for a gas fireplace?
- Valves and ignition: Confirm your fireplace uses a Millivolt valve or an electronic ignition module, and ensure the controller supports it. Some units pass voltage from a thermopile rather than powering the valve directly.
- Connectivity: Decide between RF (remote) versus WiFi-enabled controllers. RF is simple and install-friendly; WiFi-enabled models allow remote access and app-based automations but require network compatibility.
- Power and wiring: Some options rely on the fireplace’s existing power or thermopile signals. Check if you need an external power supply or if the kit wires in series with the existing line.
- Smart-home compatibility: If you use Alexa, Google Assistant, or other ecosystems, choose a model with these integrations or a neutral app that supports routines and scenes.
- Thermostat features: Consider programmable schedules, remote handsets, and timer options. Detachable thermostats can simplify placement for room-temperature sensing.
- Safety and installation: Verify wall-box fit, mounting hardware, and the device’s ability to operate within safe temperature ranges. Ensure the included wiring and receiver connections align with your valve type.
Practical questions
- Is a hub required for WiFi fireplace controllers? Most models listed do not require a hub, but verify compatibility with your router and network.
- Will these controllers power my gas fireplace? Most units pass voltage from the thermopile to the valve rather than supplying power, for safety reasons.
- Can I control these devices with voice assistants? Several models offer Alexa, Google Home, or Siri support.
- Do I need a C-wire? Some thermostats need a C-wire for full functionality; check your current wiring and whether the thermostat supports battery operation.
- Are these compatible with all gas-valve brands? Compatibility varies by model and valve type; always verify with your fireplace’s model and installation guide.
