Do Warmup Thermostats Need Wi-Fi? Smart Home and Matter Compatibility

3 min read · Updated Nov 2026

No. Warmup thermostats don’t need Wi-Fi to heat your floor. The 7iE, Terra, 6iE, and 4iE thermostats have built-in Wi-Fi but can heat your floor without it. To use the MyHeating app, remote control, SmartGeo, and energy monitoring features, the thermostat must be connected to Wi-Fi. The 7iE is the only Warmup thermostat that is fully compatible with Matter, so it works with Apple Home, Google Home, Amazon Alexa, and other smart home ecosystems. If you want floor heating that integrates seamlessly with your smart home, choose the 7iE. The EZPT and 3iE do not have Wi-Fi.
