This product is advertised for sale in the UK but it is not compatible with the UK hub due to different frequency set up This should be removed from the UK Amazon store

Great product!

Excellent product!

From 1 to 10 the sound is loud about 7. Enough to alert neighbours and may be worry an intruder. Needs to hide it, because it is battery operated, if the intruder spot it, will be easy to switch it off. Require a hub, expensive as well. It does the job.

It’s loud! It’s easy to connect and mount it anywhere. YoLink products work really well with great range.

PRO Features Diversity of product line Integration capabilities as a smart home device Low cost Battery Life CON 1/4 Mile range advertised likely clear line of site In wooded area reliable range was more like 300 feet Antennas, range extenders not available Unsupported range extender works but limits features Some limitations For house monitoring of crawl space temp/humidity, water leak detection, motion in attic etc., the product line works extremely well and has excellent smart home integration. The goal was to simplify install, minimize/eliminate wiring for sensors, and to gain smart device capabilities. When working for external device monitoring such as driveway gates, package delivery box notification at a range of 450 feet through wooded areas challenges were uncovered. For the package delivery box, the original concept was to mount a garage door sensor flush (horizontal) on the bottom of the lid that would toggle when the lid was opened. From what I could glean the device is designed to be installed on the inside of a garage door (vertical) with door closed. There was not a software option on this sensor to alert on normally open vs normally closed. Therefore a bracket needed to be assembled to mount the sensor in a vertical position for the device to operate. Would be nice if the device offered this option. During the process the range was learned to be a challenge. Moved hub outside, tried different orientations to try to optimize internal antenna (vertical / horizontal) different sides facing device and was not able to mitigate signal limitation. Yo-link does not offer an antenna, and/or range extender. Found a helpful "non-supported" solution to create a signal relay solution. This uses a yo-link Security Siren & Alarm controller and yo-link Outdoor contact sensor. Between these two devices a relay is required. I found and electronic relay with NO normally open and NC normally closed output contacts; "OONO DPST 1NO 1NC 8Amp Power Relay Module, AC/DC 12V Control Voltage" which worked perfectly. Configure the remote device to trigger the Alarm controller. Replace with siren with the input to the relay module. Attach the contact sensor to either the NO/NC contacts as appropriate for your project. This solved the range issue in this case. However, the ability to monitor if the device remains open and is not closed is lost. A goal was to add this solution to the driveway gate and obtain a notification if the gate was not closed. At this time I do not know a solution to the range challenge combined with some of the additional features yo-link offers. I am using these devices outside of their intended design, so I will still rate them highly. However, it would be nice for yo-link to have an extended range solution that supports all of the device capability as well as a tilt sensor (garage door sensor), that allowed the NO/NC configuration to be modified. Overall I have been impressed.
