WiFi Door Sensor: Smart Door Open/Closed Detectors, Wireless Window Sensor with App Notification Alert, Contact Sensor for Home Security, Compatible with Alexa Google Assistant (4pack)

Excellent

Alarm is way too loud. Like the do not disturb feature but won't work for me.Wifi door window sensor smaller better, just short ding for alert.

Pros:1. Good price with the 15% coupon.2. They actually work well.3. I recommend trying these.Cons:1. It has a couple of seconds delay. Probably due to going thru its server before reaching alexa server.2. WiFi reception is a bit weak. Make sure you have direct light of sight between you wifi router and this sensor. Walls will weaken the reception.Battery life:1. Don't know yet, I have these running for a couple of weeks now. So far so good.

I want the independent garage lights to turn on when i open the back door of the garage or I open either of the garage doors. I have a motion sensor light switch that turns on the independent garage lights but it's in a corner next to the door entrance to the house and by then i dont need the lights to be on so i got these and connected them to the Tuya App, then connected that to Alexa, then the motion sensor light switch through it's app to also connect to Alexa and i created the routine in Alexa to turn on the motion sensor light switch if any of these go into an 'open' state. it works like a charm
