Wireless doorbell with LED temperature indicator, waterproof, with 2 plug-in receivers, 150m range and 38 melodies. [Battery not included]

Battery-free: Our wireless doorbell uses PUSH-RF technology. A simple press of the button converts kinetic energy into an electrical signal, triggering your doorbell. No more worrying about batteries. More convenient, more energy-efficient, and more powerful than previous models. IP44 weatherproof and temperature display: Thanks to its IP44 weatherproof design, the transmitter is made of non-toxic, safe, and recyclable ABS. It operates in temperatures ranging from -20°C to 65°C and is weatherproof. Its LED display shows the temperature in Celsius or Fahrenheit when the receiver is not ringing and can be used as an indoor thermometer. 38 pleasant ringtones and melodies: Enjoy 38 classic melodic ringtones with adjustable volume and a diverse selection to suit all your needs. Four volume levels are available, from 0 dB to 100 dB, allowing even the elderly to hear a gentle melody every time someone rings your doorbell. The LED indicator provides a visual alert (a very practical feature for the hearing impaired). Long wireless range: With a wireless range of 150 m, and thanks to the 2 included receivers, you won't risk any interference with other wireless devices in your home or your neighbors' homes. You'll never miss a visitor again, even if you're in several rooms or on another floor. Ideal for homes, offices, hotels, villas, hospitals, apartments, schools, and other compatible locations. Easy to use: Its practical and intuitive design offers an optimal user experience. Simply remove the protective film from the transmitter and stick it near your door, then plug in the receivers. All URESMAT wireless doorbells can be paired and controlled together. Feel free to contact us for any assistance.
