Outcome
This companion comparison post compares Fireplace Control to the top live alternatives found on April 10, 2026, including current Amazon and Alibaba checks.
Source Device
The source device is a DIY fireplace control switch, built using an ESP-01S with Tasmota firmware and a relay board, costing less than $10. It replaced an $80 Z-Wave switch that had reliability issues and has been operating successfully for over three years. This switch is described as a highly used device, especially during winter, indicating a need for reliable and potentially locally controlled alternatives for fireplace operation.
Top Alternatives
- Shelly 1 Gen4 Smart Relay: The Shelly 1 Gen4 is a compact, Wi-Fi, Zigbee, Bluetooth, and Matter-compatible smart relay with dry contacts, making it ideal for controlling devices like a fireplace. It offers robust local control capabilities and strong integration with Home Assistant, providing a more polished and reliable alternative to a DIY ESP-01S solution while retaining flexibility and advanced features. It supports a wide voltage range (110-240V AC or 24-48V DC) and handles loads up to 16A.
- Sonoff Basic R3 Smart WiFi Switch: The Sonoff Basic R3 is a low-cost, Wi-Fi smart switch that offers a 'DIY Mode' with a REST API, allowing for local control and integration with home automation systems like Home Assistant without requiring firmware flashing. This makes it a direct competitor to the DIY ESP-01S solution, providing similar hackability and affordability but in a more consumer-ready package.
- Zooz ZEN16 MultiRelay: The Zooz ZEN16 MultiRelay is a Z-Wave device specifically designed for dry contact applications, making it highly suitable for controlling a gas fireplace. It offers three individually controlled relays and physical inputs, addressing the Z-Wave category where the source device had reliability issues with a more robust and purpose-built solution. It features the new 800 series Z-Wave chip for improved range and signal.
