Once it's on, you can set temperatures and schedules from your smart home system, or adjust it using the dial.\u003c\/p\u003e\n\u003cp\u003eThe screen shows the target and current room temperature at a glance, and you can rotate it so it's the right way up however your valve is mounted. It's compact enough to fit around awkward pipework, quiet enough that you won't hear it at night, and runs for up to six months on two AA batteries.\u003c\/p\u003e\n\n\u003cp style=\"padding: 0.5em; border: 2px solid orange;\"\u003eThis is a Zigbee device, so you'll need a compatible hub to use it with your smart home system - it won't connect directly to your Wi-Fi.

Zigbee2MQTT supports everything from version 2.12.1. External temperature sensors are set up with an automation.\u003c\/li\u003e\n\u003cli\u003eUse alkaline AA batteries - rechargeable NiMH ones only provide 1.2V, which won't keep it going for long.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eWhat is Zigbee?\u003c\/h3\u003e\n\u003cp\u003eZigbee is a low-power wireless standard made specifically for smart home gadgets like sensors, switches and lights. It sips power so it's perfect for battery-powered devices that need to keep going for months (or years) between battery swaps.\u003c\/p\u003e\n\u003cp\u003eZigbee devices form a mesh network, with mains-powered devices like smart plugs and bulbs passing messages along for their neighbours. The more devices you add, the stronger and further-reaching your network gets.\u003c\/p\u003e\n\u003cp\u003eIt also works locally, so your devices keep chatting to your hub even if your internet decides to take the day off. That means snappier responses, better reliability and improved privacy. It's supported by loads of manufacturers too, so mixing and matching brands is no problem.\u003c\/p\u003e\n\u003cp\u003eWant to learn more?
