巴哈马采购需求：ZigBee WiFi 设备 ODM、智能家居、智能建筑、物联网解决方案、楼宇管理系统、智能恒温器温度控制器

We are looking to procure several smart devices for our building automation needs. Specifically, we need around 20 units of Zigbee thermostats, 20-25 PIR sensors with temperature and humidity features, and some clamp-on energy meters. Additionally, we're interested in optional DIN-Rail relays, leak sensors, door/window contacts, and a Zigbee gateway or compatible mini-BMS platform. Could you provide us with pricing, availability, and lead times for these items? We'd also like to get details on setup documentation, customization options, licensing fees, and compatibility (e.g., Zigbee 3.0). Please include compliance certificates like CE, FCC, and RoHS, as well as warranty info and installation support if available. Any other product recommendations that fit our smart building goals are welcome!
