The sensors are especially suitable for those who already have a ZigBee hub or plan to integrate smart devices more widely. Since they operate via the ZigBee standard, they are not a suitable choice for users who would like a direct connection via a WiFi network or operation without additional components. It is especially worth noting that for proper use, an appropriate central unit is required, so potential users should first check compatibility with their existing ecosystem.\u003c\/p\u003e\u003cp\u003e \u003cem\u003eRecommendation source: Enaa guides and team experiences.\u003c\/em\u003e\u003c\/p\u003e\u003ch2\u003e User view\u003c\/h2\u003e\u003cp\u003e These smart sensors are most often used in living and working spaces where users want to have better control over temperature and humidity - for example in living rooms, bedrooms, basements or children's rooms.
