Door Sensor, 1/4 Mile World's Longest Range Smart Home Wireless Window Door Sensor, Smart Sensor with Remote Monitor App Notifications Open Reminder - YoLink Hub Required

Door Sensor, 1/4 Mile World's Longest Range Smart Home Wireless Window Door Sensor, Smart Sensor with Remote Monitor App Notifications Open Reminder - YoLink Hub Required

Q: will these work with the zigbee hub built in to Amazon Echo Dot V4 ?

No, YoLink device uses the longest range wireless technology LoRa, not zigbee and other short range wireless technologies. Thanks!

Q: How can i link this to a simple "wall" led. Like a red light notification?

You would need to be a little creative. You can use the YoLink Relay (https://www.amazon.com/YoLink-Relay-Super-Compatible-Google/dp/B08RBSPP4F?ref_=ast_sto_dp&th=1) to turn on a low voltage LED light. If the LED is AC powered there are several YoLink smart plugs/outlets that could be used.

Q: Does it work when mounted on metal door?

Yes, it works when it is mounted on metal door.

Q: Has anyone install this on a window that would be for example broken and opened during a robbery I’ve seen a lot of videos with this on peoples doors?

It is a window/door sensor, or you can consider our YS7201-UC Vibration Sensor to get a notification in case the window was broken, and you can use the sensor to trigger YS7103-UC/YS7104-UC Indoor/Outdoor Siren to scare somebody away. Thanks!
