Review on Smart Door Sensor 2 Pack, TESSAN WiFi Window Contact Sensor Work With Amazon Alexa, Google Assistant, No Hub Required, Trigger Phone Notification, Phone Alarm, Programmable With Smart Life Devices by Carl Mayes
Waste of money: my feedback
They don’t work. I get messages between 5 minutes up to several hours AFTER the door has been opened. It’s not worth buying this. And the set up is a PITA!
- I purchased it to mount in my mailbox and lid to announce when mail has arrived, it works great!
- The system only works for about an hour and then I need to reset them by taking the battery out.
