{"product_id":"diyani-ms1-zigbee-regensensor","title":"DIYANI MS1 Zigbee Rain Sensor for Irrigation and Awning Automation","description":"\u003ch2\u003eDIYANI MS1 Zigbee Rain Sensor with IP65 for Outdoor Use\u003c\/h2\u003e\u003cp\u003eAutomatically retracting your awnings when it starts to rain, stopping garden irrigation, or receiving a notification when it rains: this requires a reliable rain sensor. The DIYANI MS1 is a compact binary sensor that does one thing: detect if it's raining. Via Zigbee 3.0, it sends a signal directly to Home Assistant as soon as water touches the snake pattern on the detection plate. No Wi-Fi, no cloud, no adapter: just two AAA batteries and a Zigbee coordinator.\u003c\/p\u003e\u003ch3\u003ePower and Connectivity\u003c\/h3\u003e\u003cp\u003eThe DIYANI MS1 runs on two 1.5V AAA batteries (not included). Power consumption is less than 1mA, allowing the batteries to last up to a year under normal use. Communication is via Zigbee 3.0; the device is a Zigbee EndDevice and requires a Zigbee coordinator. The sensor features IP65 protection: dust-tight and resistant to water jets from all directions.\u003c\/p\u003e\u003ch3\u003eDetection and Operation\u003c\/h3\u003e\u003cp\u003eThe detection plate has a snake pattern of conductive traces. As soon as raindrops bridge two traces, the circuit closes, and the sensor registers rain. The MS1 reports two states: rain (1) or no rain (0). It is not a pluviometer; the amount of precipitation is not measured. The response time is almost instantaneous: the sensor reacts as soon as water touches its surface.\u003c\/p\u003e\u003ch3\u003eMounting and Enclosure\u003c\/h3\u003e\u003cp\u003eYou can attach the sensor with the included screws and plugs, or using the enclosed sticker. Two screw holes on the back provide secure outdoor mounting. The back cover closes with a rubber seal to keep the inside dry. Mount the MS1 in an open, unsheltered location so that rain falls directly onto the detection plate.
